How long can my videos be?
You can generate AI videos up to 20 minutes long. That is the limit for faceless videos, the longest format. Other video types have shorter limits.
What is the limit for each video type?
Video type | Maximum length |
|---|---|
Faceless video (AI images, AI video, or stock) | 20 minutes |
Skeleton video | 7 minutes |
3D Talking Characters | 7 minutes |
Avatar video | 5 minutes |
AI Music Video | follows your song; uploaded songs up to 10 minutes |
AI video clips (clip generator) | 1 to 15 seconds per clip |
Script limits apply too: up to 30,000 characters and 400 scenes per video. The voice speaks about 3 words per second, so a 20-minute video needs about 3,600 words. Write your own script or let AI write it.
Why do some video types have shorter limits?
Two reasons:
- Quality. Short formats like Skeleton and 3D Characters are built for short-form platforms. Long runs of AI video clips lose consistency, so we cap them where the result stays good.
- Cost control. AI video costs credits per second. The caps stop one video from using far more credits than you expect. You always see the estimated credit cost before you generate.
Can I make a 20-minute AI video?
Yes. Use the faceless video type on the video creation page. Write or generate a script of about 3,600 words, or pick a long duration in Idea to Video mode. AI images and stock footage keep long videos affordable; AI video clips cost more per second. Check the credit estimate in the form before you start.
