Momentum / cinemaOS
Legal

Terms / 24 September 2026 v2

Terms and Licence Agreement.

Version terms-2026-09-24-v2, published 24 September 2026. It applies to accounts created with this version. Accounts created earlier keep the trial length they were given at sign-up.

A material later change will be notified and presented for acceptance where the law requires it; it will not operate retroactively.

1. Seller and contract

cinemaOS is supplied by Julien Kerknawi, trading as Momentum Studios, a Belgian sole trader, enterprise number 0648.946.826, VAT BE0648946826 (“Momentum”, “we”, “us”). Registered establishment: Jules Van Biesbroeckstraat 156, 9050 Gent, Belgium. Contact: support@mntm-studios.com.

These terms govern the cinemaOS application, Momentum account, updates, support, trial and paid subscriptions. You must be at least 18 and legally able to contract. The order summary, plan and price shown at checkout form part of the contract.

2. Service and disclosed Beta 2 limits

cinemaOS is professional macOS post-production software for Apple Silicon Macs running macOS 15 or later. Its bundled AI and media analysis run locally. Momentum does not receive your projects, footage, frames, transcripts, prompts or model output for those features and does not train models on them. Optional restoration packs are downloaded only when requested.

Beta 2 is pre-release software. Functions may change and defects may remain. Voice cloning is not supplied in this build. Automated lip sync, DCP and IMF authoring, Dolby E-AC-3 JOC and AC-4 encoding, and vendor RAW SDKs for R3D, BRAW, ARRIRAW and X-OCN are not included. Interchange import is conform-grade, not parity-complete. Local dubbing and translation depend on macOS resources installed on the Mac. Analysis and AI suggestions require professional review and are not certified measurement or creative truth.

These disclosed limits define the Beta 2 offering but do not exclude statutory conformity rights for paid software.

3. Accounts and trial

You must provide accurate information, protect your credentials and promptly report suspected compromise. You may not sell or share an account, evade device or trial controls, automate referrals, attack the service, or use it unlawfully.

  • The Complete trial lasts 30 days from verified signup, or longer where the sign-up screen or creator campaign you used offered a longer trial. The length is recorded on your account when you sign up and shown on your account page. The trial needs no card, never auto-converts and never causes a charge.
  • Valid independent referrals may extend a trial by 14 days for the new account. The person who shared the code may receive the same 14 days at most twice (28 extra days). Duplicate, self, automated, shared-device or fraudulent rewards may be refused or reversed.

4. Plans, tax and payment

Complete, which includes J.A.R.E.D., costs €9.99 / $9.99 per month excluding VAT. Teams is billed per seat at €8.99 / $8.99 excluding VAT, with a minimum of two seats and a maximum of fifty. Applicable VAT is calculated from the required billing address and added at checkout. The total is displayed before payment. Eligible businesses may provide a valid VAT number for reverse charge or exemption treatment.

Stripe processes payment details; Momentum does not store full card numbers. A subscription begins only when you choose a plan and complete checkout. It renews monthly at the then-current price plus tax until cancelled. We will give advance notice of a price increase before it affects a renewal.

5. Cancellation, failed payment and access

You can cancel at any time without a fee through the Stripe-hosted billing portal or by emailing support. Unless a statutory withdrawal or remedy applies, cancellation stops the next renewal and access continues to the end of the paid period. Confirmed payment failure, fraud, material breach or a security risk may result in proportionate suspension. You may appeal to support.

One account may activate two Macs. Offline entitlement lasts at most seven days and never beyond the underlying access period. Expiry or suspension does not permit Momentum to encrypt, delete or hold your projects hostage: opening, saving, backup, relink, recovery, local diagnostics and cancellation remain available.

6. EU consumer withdrawal

An EU consumer may withdraw from a paid subscription within 14 days of completing checkout without giving a reason. Send an unequivocal statement to support@mntm-studios.com before the period expires. We will refund amounts due, including corresponding VAT, through the original payment method without undue delay and no later than 14 days after notice.

Paid access starts immediately. If checkout separately records your express request for performance during the withdrawal period, a lawful proportionate amount may be payable for service supplied before withdrawal. Momentum will rely on a loss of the withdrawal right for digital content or services only where checkout separately captures the prior express consent and acknowledgement required by applicable law; use or download alone is not treated as a waiver.

7. Refund policy

Refunds are provided where required by withdrawal, conformity, billing-error or other mandatory law. Outside those cases, Momentum offers no contractual or automatic refund after a paid period has begun. Momentum may grant a discretionary goodwill credit or refund; doing so creates no continuing policy, precedent, admission or obligation to do so again.

8. Software licence, ownership and acceptable use

This section is the cinemaOS licence agreement. It sets out what you may do with cinemaOS, what you may not do, and the rights the law gives you whatever this section says. Each numbered paragraph of this section, and each lettered item in it, is a separate term: if one is found invalid or unfair, the others still apply.

8.1 Your licence. While you have an active trial, paid plan or Teams seat (your “entitlement”), Momentum grants you a limited, personal, non-exclusive and non-transferable licence to install and use the version of cinemaOS we supply, in executable form, for any lawful personal or commercial purpose, including work for clients. You may not sublicense it. The device limits in section 5 apply.

  • A Complete plan or trial is for one person.
  • Each paid Teams seat is for one named member at a time, on one Mac at a time. The team owner may move a seat to another person when its holder leaves or no longer needs it, but may not rotate seats so that more people use cinemaOS than the team pays for.
  • A team owner that is a business customer is responsible for its members keeping to these terms. A team owner that is a consumer must take reasonable steps to make sure its members keep to them, and must tell us about misuse it becomes aware of.
  • When your entitlement ends, the licence continues only for what section 5 keeps available: opening, saving, backing up, relinking and recovering your projects, local diagnostics and cancellation.

8.2 Ownership and reserved rights. cinemaOS is licensed, not sold. Momentum and its licensors own, or hold the rights to license, cinemaOS, its updates, the Momentum assets described in 8.9 and its documentation. Subject to 8.3 and 8.4, you receive only the rights these terms grant expressly. All other rights are reserved, and nothing in these terms grants a licence by implication. The cinemaOS, Momentum Studios and J.A.R.E.D. names and logos identify our products. You may use them to refer truthfully to cinemaOS, but not as or in your own brand, product or domain name, and not in a way that suggests we endorse you.

8.3 Open-source and third-party parts. cinemaOS includes open-source software, open model weights, fonts, LUTs and other material that others license under their own open terms (“open-licensed parts”). Their licence texts ship inside the application. They are also published, with the notices and source code those licences require, on our open-source notices page, and from Build 8 cinemaOS lists them under About cinemaOS. For open-licensed parts, their own licence decides what you may copy, modify and share, and nothing in these terms limits the rights it gives you. Those licences do not reduce Momentum’s own responsibilities to you: sections 10 and 11 and your statutory conformity rights cover cinemaOS as a whole, including those parts. In particular:

  • You may copy, modify, replace, redistribute and reverse-engineer a component that contains code under the GNU LGPL or GPL, such as the FFmpeg-based media helper, as those licences allow, including reverse engineering to debug your own changes where they require it. The complete corresponding source code of such a component, with the scripts used to build it, is published on our open-source notices page for as long as we distribute that component, and support can also send it to you. Replacing such a component with your own build, including the changes to the application’s code signature strictly needed to install and run it, does not breach 8.5 or 8.6. An update may replace your version, and we are not responsible for problems your version causes.
  • Material under a Creative Commons licence, such as the film-emulation LUTs by Pat David and the open speech models, remains under that licence, including any share-alike terms.
  • Fonts remain under the SIL Open Font License or the Apache licence.
  • Models and libraries under the Apache, MIT, BSD or similar licences, including the language and speech models J.A.R.E.D. runs on, remain under those licences.

The restrictions in this section apply only to Momentum’s own parts of cinemaOS, not to open-licensed parts. The one exception is the model use restrictions in 8.13, which the model licences require us to pass on to you.

8.4 Rights the law gives you anyway. Nothing in these terms takes away the following rights, which EU law, Belgian law and the law of the country where you live give anyone entitled to use cinemaOS. Every restriction in this section applies subject to them.

  • Back-up copies. You may make the back-up copies you need to keep using cinemaOS, for example in your usual Mac backups.
  • Observing, studying and testing. While doing anything you are entitled to do with cinemaOS, such as loading, displaying, running, transmitting or storing it, you may observe, study and test how it works to find out the ideas and principles behind any part of it.
  • Your files. You may read, convert and write the files you create with cinemaOS, including .mntm project files, for example to move your work to other software.
  • Interoperability. If you need interface information to make an independently created program work with cinemaOS, including information about cinemaOS project and interchange files, you can ask us at support@mntm-studios.com. We will provide it free of charge within 30 days. Information we have published, or have given you on request, is readily available, and decompiling to obtain it is then not permitted. Otherwise, you may decompile the parts of cinemaOS whose decompilation is indispensable for that interoperability, and only those parts. You may not use information obtained this way for any other purpose, give it to others unless that is necessary for the interoperability of the independently created program, or use it to develop, produce or market software substantially similar in its expression to cinemaOS, or for any other act that infringes copyright.
  • Error correction. Report defects to support. We correct defects that affect how cinemaOS operates for its intended purpose. If we have not corrected such a defect within 60 days of your report, you may do what is necessary to correct that defect yourself, including decompiling the parts concerned, and nothing more. This does not limit your conformity rights under section 10.
  • Any other right that mandatory law gives you, including your rights as a consumer.

8.5 No reverse engineering or modification. Except as 8.3, 8.4 and 8.16 allow, you may not:

  1. decompile, disassemble or decrypt cinemaOS, or otherwise reverse-engineer its code to obtain its source code, shaders, prompts, grammar or capability catalog;
  2. modify, adapt, translate or patch cinemaOS, or make derivative works of it;
  3. inject code or libraries into cinemaOS or its helpers, or alter the licensing, entitlement or update responses they receive, in order to change how they behave;
  4. copy cinemaOS, except to install and use it under 8.1 and to make the back-up copies 8.4 allows.

This paragraph does not stop you from:

  • observing cinemaOS while it runs, for example by watching its network connections with a firewall or network monitor;
  • blocking its connections on your own Mac (some features then stop working, and the offline limit in section 5 still applies);
  • choosing not to install an update;
  • changing settings, or adding your own presets, looks, templates and plug-ins through the features cinemaOS provides;
  • using macOS automation, accessibility and assistive tools, any automation or agent interface cinemaOS provides, and supported Audio Unit, VST3 and OFX plug-ins installed in the normal way, as long as they do not alter cinemaOS’s licensing, entitlement or security behaviour.

Non-public information about cinemaOS, such as its source code, server-side systems, signing and licensing keys, unreleased builds and documentation we mark confidential, is Momentum’s confidential information and may be protected as a trade secret. This paragraph is a contractual duty not to obtain it by reverse engineering beyond what 8.3, 8.4 and 8.16 allow.

8.6 No bypassing licensing, trial or security controls. You may not do any of the following, or help anyone else to do them:

  1. crack, patch, emulate, disable or circumvent cinemaOS’s licence, activation, entitlement, offline-access, device, seat or trial controls;
  2. use a cracked, patched or key-generated copy of cinemaOS, or an unofficial licence or activation server;
  3. tamper with how cinemaOS’s code or updates are signed or verified, or with cinemaOS’s own security controls, except as 8.3 allows for open-source components;
  4. extract the keys, tokens or licence leases that cinemaOS stores on your Mac, or share or misuse them;
  5. copy licence data, or change your Mac’s clock, to extend offline access or to use cinemaOS on more Macs than allowed;
  6. spoof or change hardware identifiers, or use virtual machines, extra user accounts or other devices, to appear as a different Mac in order to get another trial or exceed the device or seat limits;
  7. make, share, sell or publish tools, patches, keys or instructions for doing any of these things.

Choosing not to install an update, postponing it or turning off automatic updates is not a breach; a feature or service that needs a newer build may then stop working until you update. Normal backups, restores and Migration Assistant transfers are allowed; a restored or migrated Mac may need to be signed in again.

8.7 One free trial per person and per Mac. Each person, and each Mac, can have one free cinemaOS trial, including a trial started under an earlier version of these terms. A referral extension lengthens that trial; it never starts a new one. You may not:

  1. open more than one account, or an account in a false name or in someone else’s name, to get more trial time;
  2. start a trial with an email address that expires or at which you cannot keep receiving email, or with a variant of your own address that reaches the same mailbox, for example with a “+” tag, or with added dots at providers such as Gmail that ignore them. A relay address, such as Apple’s Hide My Email, is fine if it keeps working;
  3. share, sell, trade or farm trial accounts or referral codes.

If someone else already used a trial on your Mac, such as a previous owner, a family member or a colleague, write to support and a person will review it. We check trial eligibility only in the ways our privacy notice describes and on the legal basis it states, not on the basis of your acceptance of these terms, and we keep the information used for those checks no longer than it says. We may hold a new trial for review by a person when unusually many trials start from the same network or Mac. If a trial breaks this rule, we may end it under 8.17. Nothing is charged, and you can still buy a plan.

8.8 No sharing, resale or hosting. You may not:

  1. sell, rent, lend, lease, sublicense or transfer cinemaOS, your licence or a Teams seat;
  2. share your account, or let anyone else use cinemaOS under your licence, except a team member using a Teams seat;
  3. offer cinemaOS as a hosted, remote-access, time-sharing or rental service in which other people operate it.

Using cinemaOS to make work for your clients, letting clients watch and review that work, and showing cinemaOS to others while you operate it, for example when teaching, presenting or screen sharing, are allowed.

8.9 Bundled assets and your work. “Momentum assets” means the creative material supplied with cinemaOS that Momentum made or licenses from others, whether or not it is protected by intellectual-property rights, other than the open-licensed parts in 8.3. It includes the Filmgrade pack (looks, LUTs, texture maps and datasets); the Glass & Alloy interface sounds, the Momentum Dial sounds and other bundled sounds; Atelier scene plates, catalog stills, templates, titles and motion presets; Spatial Theatrics rooms and scenes; Design Library presets and layouts; colour, effect and audio presets; J.A.R.E.D.’s capability catalog, grammar, prompts and indexes; and the documentation, interface artwork, icons and key art. Fonts are not Momentum assets.

As between you and Momentum, you own your projects and everything you create and export with cinemaOS (“your work”). Momentum claims no ownership of your work and no licence to use it, except the limited permission needed to handle files you choose to send us, such as support attachments, only to give you the help you asked for and for as long as our privacy notice states. Your work can still be subject to other people’s rights in your source material, to the licences of open-licensed parts you use (for example the share-alike terms of a CC BY-SA LUT you export) and to 8.13 for images and footage produced with the models it covers.

Where your work includes a Momentum asset, for example a Filmgrade look in a graded film or a bundled sound in a mix, Momentum, or whoever licensed the asset to us, keeps whatever rights it has in the asset, and you receive a worldwide, royalty-free and permanent licence to use, copy, publish, broadcast, distribute and sell your work with that asset in it. Your clients, distributors and audiences may use your work on the same basis. This licence continues after your plan ends. It has one limit: you may not distribute sounds generated from Momentum’s sound presets on their own, as a sound library, sample pack or similar collection. Using them in your productions is always allowed.

Your work includes project files; interchange and delivery exports such as FCPXML, AAF, OTIO and EDL; caches; and grades, looks, LUTs and DCTLs that you export with cinemaOS’s export features to finish or deliver your work in other software, for example for your colourist or finishing house, even when they contain a Momentum asset. You may give such exports to the people working on that work, but you may not distribute them on their own, or as a pack or collection, to anyone else.

Outside your work, you may not extract, copy or redistribute Momentum assets for use outside cinemaOS, or sell, share or publish them on their own or as a pack, library, preset, template or LUT collection. Looks, presets, templates and LUTs you build yourself are yours to export and share, unless they reproduce a Momentum asset with no more than minor changes, such as re-saving, renaming or re-encoding it. These restrictions apply to Momentum assets whether or not they are protected by copyright or other intellectual-property rights.

You may show cinemaOS and Momentum assets in screenshots, screen recordings and quotations in tutorials, reviews, comparisons, teaching, support requests and your portfolio. Nothing in this paragraph limits an exception to copyright or database rights that the law makes mandatory, such as quotation, parody or extracting insubstantial parts of a database.

You are responsible for having the rights you need in your source material, for keeping independent backups, and for checking automated and AI-assisted results before delivery. This does not limit your conformity rights under section 10. You may not use cinemaOS to infringe other people’s rights, to break the law or to cause harm.

8.10 Our online services. Use our account, licensing, update, support and portal services only through cinemaOS, the account portal and the links we publish. You may not:

  1. access them with bots, scrapers, crawlers or scripts, or create accounts or sign in with bots or scripts or in bulk (password managers, passkeys and “keep me signed in” are fine);
  2. probe, scan or load-test them, or interfere with how they work;
  3. reverse-engineer their interfaces to build another client.

Testing our servers is not covered by 8.16 unless we agree to it in writing first.

8.11 Competing products. A “competing product” is software or a service for video editing, colour grading, audio post-production, motion graphics or AI-assisted editing that is offered to others. You may not use cinemaOS, Momentum assets, our documentation, pre-release builds or non-public information about cinemaOS to:

  1. copy code, interface artwork, sounds, presets, text or other protected expression from them into a competing product;
  2. record, scrape or systematically capture the interface, assets, catalogs or documentation of cinemaOS in order to reproduce them in a competing product;
  3. use information obtained by decompiling cinemaOS under 8.4 for any purpose other than interoperability, or to develop, produce or market software substantially similar in its expression to cinemaOS;
  4. develop or improve a competing product with confidential information we gave you, such as non-public documentation, roadmaps or information we disclosed about pre-release builds.

None of this affects the rights in 8.4, honest reviews and comparisons, or anyone’s freedom to develop their own software independently, including software with similar functions.

8.12 AI training and text and data mining. You may not use cinemaOS, Momentum assets or our documentation:

  1. to train or fine-tune an AI model;
  2. to build a dataset, or to carry out text and data mining on them.

Momentum expressly reserves its rights in cinemaOS, Momentum assets and its documentation against text and data mining, as Article 4(3) of Directive (EU) 2019/790 allows. This paragraph does not apply where the law allows mining whatever a contract says, such as text and data mining for scientific research, and it does not affect your work, the rights in 8.4 or the open-licensed parts in 8.3.

8.13 AI model use restrictions. The Real-ESRGAN ×4, BSRGAN ×4 and MPRNet Denoise restoration models bundled with cinemaOS are licensed to us under the CreativeML OpenRAIL-M licence, which requires us to pass its use restrictions on to you. Those restrictions are set out in full, in the licensor’s own words, in Appendix A, which forms part of these terms. They apply to the models, to anything derived from them and to how you use images and footage produced with them. In short, you may not use them:

  • in a way that breaks any applicable law or regulation, in any country;
  • to exploit or harm children, or to try to;
  • to create or spread verifiably false information meant to harm others, or personal information that can be used to harm someone;
  • to defame, disparage or harass anyone;
  • for fully automated decisions that adversely affect a person’s legal rights or that create or change a binding obligation;
  • to discriminate against or harm people or groups because of their social behaviour, their known or predicted personal or personality characteristics, or legally protected characteristics;
  • to exploit the vulnerabilities of a group defined by age or by social, physical or mental characteristics so as to distort the behaviour of a person in that group in a way likely to cause that person or someone else physical or psychological harm;
  • to give medical advice or interpret medical results;
  • to produce information for use in justice, law enforcement, immigration or asylum processes, such as predicting that someone will commit fraud or a crime.

The Sortformer speaker-diarisation model carries this notice: “Licensed by NVIDIA Corporation under the NVIDIA Open Model License.” Its Core ML conversion is also offered under CC BY 4.0. NVIDIA’s licence, including its Trustworthy AI terms and its rule against bypassing, disabling or weakening the model’s safety guardrails, applies between you and NVIDIA. It ships with the app and, with the Trustworthy AI terms as they stood on 24 September 2026, is published on our open-source notices page. We do not add those terms to this contract, and a later change by NVIDIA does not change these terms.

8.14 Pre-release and test builds. A beta, pre-release, test or Local QA build that we give you outside our public release channel is not an entitlement. We license it to you alone, only for the testing we asked for and only until its test period ends, and the rest of this section applies to it. Until we release that build publicly, you must keep it and any non-public information about it confidential, must not share, upload or redistribute it, and must not publish screenshots, recordings or benchmarks of it without our written permission. It may stop working on a set date. Stop using it and delete it when its test period ends or when we ask. If you signed a tester or confidentiality agreement with us, it also applies; if it conflicts with this paragraph, the signed agreement prevails for that build. Builds we release publicly, even if labelled beta, are not covered by this paragraph.

8.15 Notices and branding. You may not remove, hide or alter copyright, licence, attribution or trade mark notices in cinemaOS, its acknowledgements or its licence files, or labels it shows, such as a pre-release or Local QA label. You may not rebrand cinemaOS, or present it or a modified copy of it as your own product. You do not have to credit cinemaOS in your own work.

8.16 Security research. Good-faith research into the security of your own licensed copy of cinemaOS, on your own Mac, is allowed even where 8.5 or 8.6 would otherwise forbid it, as long as you:

  • report what you find privately and promptly to security@mntm-studios.com;
  • do not access other people’s data, accounts or devices, and do not test our servers without our written agreement;
  • do not use a finding to bypass licensing or unlock paid features, and do not share tools or methods that do;
  • do not disclose the issue publicly until we release a fix or 90 days have passed since your report, whichever comes first, and then describe the vulnerability and how to protect against it without publishing our source code, keys or tokens, or working instructions for bypassing licensing; and
  • keep to the law.

We will not treat research that follows these rules as a breach of these terms, and we will not bring a claim under copyright or trade-secret law, or file a complaint, against you for it. You may also report the issue to the Centre for Cybersecurity Belgium (CCB).

8.17 If these rules are broken. We respond in proportion to how serious a breach is and whether it is repeated:

  1. Except in the cases in (d), we first tell you by email what we believe is wrong and give you at least 14 days to stop, put it right or explain.
  2. If the breach continues after that period, we may suspend the affected trial, licence, device or seat.
  3. If a serious or repeated breach is not remedied after notice, we may end your licence and account under section 13.
  4. Only for cracking or patching cinemaOS, using a cracked copy or an unofficial activation server, misusing keys or leases, redistributing cinemaOS itself or licence keys, trial fraud under 8.7, or an urgent security risk, may we suspend the affected trial, device, seat or licence at once. We then tell you why within 2 working days. Suspending a trial obtained by fraud does not affect a separate paid plan unless that plan is itself involved.

A person at Momentum reviews the evidence before we suspend or end access for a breach or, for a suspension under (d), within 2 working days after it. Automated checks may refuse a new trial or a device activation; you can ask for a person to review that. We do not add hidden monitoring to detect breaches: the app and our services collect only what our privacy notice describes. You can contest any decision by replying to our notice or writing to support. We answer within 7 days; if we do not, we restore access until we do. Your rights under section 14 remain.

If a suspension turns out to be unjustified, we restore access at once and add the lost time to your plan or trial, without affecting your other rights, including a price reduction or damages. A paid plan does not renew, and you are not charged, while it is suspended. You may cancel at any time.

Suspension or termination never takes away your work: section 5 keeps your projects available, and your licence to Momentum assets in your work continues. If we end a paid plan under this section, you are not charged again. Refunds follow section 7 and mandatory law, and are never reduced to cover a loss we claim from a consumer. We may ask a court to stop a breach and to award compensation for the loss it actually caused. We do not charge consumers fixed penalties. Before we close an account, we give you at least 14 days to download your invoices and export your account data, or we send them to you.

8.18 Additional terms for business customers. If you are a business customer:

  1. you are responsible for everyone who uses cinemaOS through your account or seats, and for their compliance with this section;
  2. on our written request, at most once a year or when we have a concrete reason to suspect a breach, you will confirm in writing within 30 days how many people and Macs use cinemaOS under your plan. We will not inspect your premises or computers;
  3. if cinemaOS was used without the plans or seats needed, you will pay for them at our list price for the whole period of that use, as agreed minimum compensation, without limiting our right to prove and claim a greater loss;
  4. you will keep non-public information about cinemaOS, including pre-release builds, confidential;
  5. if you publish a performance comparison that includes cinemaOS, you will state the cinemaOS version, Mac model and settings used;
  6. we may set off against a refund any amount you owe us that is due and undisputed, or that a court has fixed;
  7. the indemnity in section 11 covers breaches of this section 8 by you, your staff and your team members.

This paragraph continues to apply for 12 months after the contract ends.

9. Updates and availability

Updates are cryptographically signed. Beta features may be added, changed or removed, and compatibility can require a minimum build for new entitlements. We will provide updates required by mandatory conformity law. Account, email, billing and update infrastructure may be unavailable for maintenance, security incidents, provider outages or events beyond reasonable control.

10. Warranty and remedies

Consumers retain every mandatory Belgian and EU conformity remedy, potentially including repair or update, proportionate price reduction, or termination and refund. These rights are free and are not reduced by Beta status.

To the maximum extent lawful, Beta 2 and its non-mandatory services are otherwise supplied “as available”. Momentum does not promise uninterrupted or error-free operation, compatibility with every media file or third-party system, preservation of unsaved work, or that automated output is suitable for broadcast, delivery, legal, medical, safety-critical or other regulated use.

11. Liability allocation

Nothing excludes liability that cannot lawfully be excluded, including liability for fraud, wilful misconduct, death or personal injury caused by negligence, or mandatory consumer remedies.

For a consumer, Momentum is responsible only to the extent and within the limits permitted by mandatory law. Momentum is not responsible for loss that was not reasonably foreseeable when the contract was made, or for business loss arising from a consumer’s non-business use.

For a professional or business customer, to the maximum extent permitted by law: Momentum is not liable for indirect or consequential loss, lost profit, revenue, opportunity, goodwill, contracts, anticipated savings, production delay, client claims, or loss or corruption of data that an appropriate backup would have prevented; and Momentum’s aggregate liability arising from Beta 2 during any rolling 12-month period is capped at the fees that customer actually paid to Momentum for cinemaOS during that period.

A professional customer will defend and indemnify Momentum against a third-party claim arising from that customer’s unlawful content, infringement of third-party rights, or material breach of section 8, except to the extent caused by Momentum. This indemnity does not apply to consumers acting outside a trade or profession.

12. Force majeure

Neither party is liable for delay or failure caused by circumstances beyond reasonable control, including widespread network or cloud failure, government action, labour disruption, natural disaster, war, epidemic or failure of essential third-party infrastructure. This does not excuse payment already due or prevent a consumer exercising mandatory termination rights.

13. Termination and survival

We may terminate for an uncured material breach after reasonable notice, or immediately for fraud, unlawful conduct or an urgent security threat. Provisions concerning ownership, payment already due, liability, indemnity, governing law and dispute resolution survive. Account deletion does not itself cancel a Stripe subscription; ask support to perform both or cancel first in the billing portal.

14. Governing law and disputes

Belgian law applies, without depriving a consumer of mandatory protection or venue in the consumer’s country of residence. Courts in Ghent, Belgium have jurisdiction for professional customers, subject to mandatory law.

Please first send a written complaint to support so we can try to resolve it. A Belgian consumer may then contact the independent Consumer Mediation Service, North Gate II, Boulevard du Roi Albert II 8 bte 1, 1000 Brussels, Belgium, contact@consumerombudsman.be, consumerombudsman.be. The former EU Online Dispute Resolution platform was discontinued on 20 July 2025.

Appendix A. CreativeML OpenRAIL-M use restrictions

This appendix reproduces, without change, Attachment A of the CreativeML Open RAIL-M licence dated 22 August 2022, under which the Real-ESRGAN ×4, BSRGAN ×4 and MPRNet Denoise models are licensed.
