AI MP4 Video Extender – Make Your MP4 Videos Longer with AI
Yes, you can extend MP4 videos with AI! Upload your MP4 file and our AI will generate new frames to continue your footage seamlessly. The format doesn't matter to AI – what matters is creating smooth, natural extensions.
Can You Extend an MP4 Video with AI?
Absolutely! MP4 is just a container format for video and audio – AI video extension tools work with the actual video content inside. Most AI video extenders support MP4 since it's the most common format. Upload your MP4, and the AI processes the frames, generates new content, and outputs an extended MP4.
Upload MP4 → AI processes frames → AI generates extension → Download new MP4. It's that simple.

- Use high-quality source files – AI can't fix heavy compression artifacts
- Keep input clips short (under 60 seconds) for best results
- Extend natural scenes like water, sky, or crowds for most realistic output
- Check the output format – most tools output MP4 by default
- Save your original file – always keep a backup before processing
