An AI video extender uses the final frames of an existing clip as context, then generates new footage from your continuation prompt. Unlike looping or slowing a clip, it creates the next part of the scene.
Sign in, upload one MP4 or MOV file, and describe the next action, camera movement, and scene ending. Choose a model, extension length, and quality, then generate and download the continuation.
You need to sign in before generating. New users receive trial credits, and each generation uses credits based on the selected model, duration, and quality. Video Extension does not include a separate free or unlimited allowance.
You can upload one MP4 or MOV file up to 50 MB. ChatArt exports the generated video as an MP4, with available quality from 360p to 4K depending on the selected model.
You can add 1 to 15 seconds per generation. Available duration options depend on the selected model.
Current options include Seedance 2.0, Seedance 2.0 Fast, Seedance 2.0 VIP, Seedance 2.0 Fast VIP, Kling 3.0, and PixVerse V6.
ChatArt uses the final frames of the source clip and your continuation prompt to carry the subject, motion, camera direction, and visual style into the new footage. Results vary with source quality, model choice, and prompt clarity.
Clips with a clear subject, visible motion, stable lighting, and an ending that naturally continues give the AI more useful context. Abrupt cuts, crowded scenes, or text-heavy frames can be harder to continue smoothly.
Yes. Upload an MP4 or MOV created with an AI video generator, then describe the next action or camera movement to continue the clip in ChatArt.
AI video extension generates new frames that continue the scene. Looping repeats existing footage, slow motion retimes the same frames, and frame interpolation only creates frames between existing moments.
