What should I watch out for with AI in video & film production?

Arrange consent from the people depicted and, for voice cloning or lip-sync, from the actor or speaker. Check per tool what happens to uploads. CapCut may use your input and output for training under its standard terms (not on Enterprise), VEED does so on the free plan, and Descript does so unless you opt out. Runway (Bytedance, Singapore) stores data in Malaysia, Singapore and the US and receives a worldwide, perpetual licence to your content. Adobe, Kapwing, Flawless, Moments Lab and Dubformer state that they do not train on your content, Happy Scribe only with your permission. For unreleased client material, choose a tool with a data processing agreement and, where possible, EU storage or local processing.

Ask the provider explicitly where data is stored and processed.
Keep a professional in the loop: raw footage almost always contains personal data: faces and voices of people on screen, and with voice cloning or face manipulation you work with biometric data.

Latest developments

26 October 2026Cloudflare Workers AI: GLM-5.3 leaked 155 answers between customers

Cloudflare reported that GLM-5.3 on Workers AI (@cf/zai-org/glm-5.3) returned data from other customers' requests in 27 answers between 9 August and 2026 September 155. Only prompts above 681,280 tokens were affected; the cause was a KV cache that was too small in the hosting configuration, not the model itself. Cloudflare found no evidence of misuse and fixed it on 9 September. If you used very long prompts containing personal data via Workers AI in that period, assess whether a data breach has occurred. source
