AI Video Extender: Continue Your Scene with AI

Yes, you need to sign in before generating. New users receive trial credits to try Video Extension. Credit use varies by model, extension length, and output quality.

Upload one MP4 or MOV file up to 50 MB. ChatArt exports your result as an MP4 and automatically matches the output quality to your source clip and selected model. Supported output options currently range from 360p to 4K.

Depending on the model, you can extend a video by 1 to 30 seconds in one generation. Choose a shorter continuation for a quick beat or a longer extension when the scene needs more time to develop.

Choose from Seedance 2.5, the Seedance 2.0 family, Kling 3.0, and PixVerse V6. Each model offers different duration and output options, so you can pick the one that best fits your clip.
