What is a synthetic AI video?

A video generated by an AI model from text, photos or audio instead of being filmed. Nothing in it was recorded by a camera.

Do I have to label synthetic video?

When it looks realistic, yes on YouTube and TikTok, and the EU AI Act adds a disclosure duty for deep fakes. Clearly unrealistic content, such as cartoons, needs no YouTube disclosure.

Is synthetic AI video the same as a deepfake?

No. A deepfake imitates a real person or event; most synthetic video shows made-up people, products or places. Using a real person's face needs their permission.

Synthetic AI Video: What It Is and the Rules

Synthetic AI video is footage generated by an AI model from text, photos or audio instead of being filmed with a camera. YouTube and TikTok require a label when such video looks realistic, and in Reviral's Cinema studio a 5-second synthetic clip with Seedance 2.5 costs 115 credits (~$1.43).

The labelling rules

YouTube requires creators to disclose AI-generated or altered content that seems realistic, such as making a real person appear to say something they did not, or a realistic scene that did not happen; non-realistic content and minor edits need no disclosure. TikTok requires a label on AI-generated or significantly edited content that shows realistic-looking scenes or people.

In the EU, Article 50 of the AI Act requires providers of systems that generate synthetic video to mark the output as artificially generated in a machine-readable way, and people who publish deep fakes to disclose it; the AI Act site gives 2 August 2026 as the date it applies.

How to make a synthetic video

Scenes and products: the Cinema studio runs video models such as Seedance 2.5 (115 credits (~$1.43) for 5 seconds), Veo 3.1 Fast with sound (106 credits (~$1.32) for 8 seconds) and Wan 3.0 (99 credits (~$1.24) for 5 seconds), from a written prompt and optional reference photos.

Synthetic presenters: the UGC studio puts a generated or uploaded face on camera holding your product and saying your lines, 15 seconds for 278 credits (~$3.47).

You must have the rights to any face or voice you upload; your own face is fine. Reviral's terms say you own the videos you generate.

Synthetic, deepfake and edited video

Synthetic video is made from nothing filmed. A deepfake is synthetic or altered video that makes a real person appear to do or say something they did not, which is why the rules above focus on realistic people and events. Editing filmed footage, such as colour or cuts, is not synthetic video.
