Start replacing peopleWhat to upload
To create a Video Recast, prepare a 5–15 second MP4 video and 1–4 character images, one for each role. No continuous shot can exceed 15 seconds. For several people or changing shots, describe who should replace whom. Your video keeps the original frame shape, with 768p or 1080p quality. Sign in to use account credits; the cost depends on video length and quality, with partial seconds rounded up.
Use JPG, PNG or WebP character images, up to 8 MiB each. Your library can store MP4 files up to 50 MiB, but images and video for one recast must total no more than 32 MiB. The video width-to-height ratio must be 0.4–2.5, with no continuous shot longer than 15 seconds. Choose clear people with uncovered faces and fewer cuts. File size and total video length are checked automatically.
Try the Hotel Lobby two-person template
- Open the Hotel Lobby two-person template and watch its sample. To use your own video, choose Video Recast on the homepage and add an MP4. Selecting a video or template does not charge you or start creation.
- Prepare two clear character images, one per role. If using real people, obtain each adult’s consent to the AI processing and intended scene. In Hotel Lobby, image 1 is assigned to the left role and image 2 to the right; use Swap photos to switch them.
- Choose Normal to keep the sample video sound. Select 10 or 15 seconds and 768p or 1080p quality. Other music styles create new sound. For your own video, choose Video Recast to keep its original sound.
- Check the cost beside the creation button. Sign in to use account credits, or choose a one-time template video pack. Homepage Video Recast uses account credits. Confirm your rights and permissions, then select Create video. Signing in or paying alone does not start creation.
- Watch the progress on the page. When finished, check the faces, left and right positions, movement and sound, then download your video. If the result is unclear, check the current task first. Retry as directed after a confirmed failure to avoid paying twice.
This sample video shows the Hotel Lobby template’s scene, movement and original sound. AI creates a new video with your character images, so faces, movement and details may vary. Check your own finished video.
Check your video and get help if needed
Faces, outfits, left and right positions or lip sync may differ from what you expected. Check that your photos and video are clear, the right people are selected and no shot exceeds 15 seconds before trying different uploads. Creating another version costs credits again. Confirmed failures return the charged credits with their original expiry. A task with an unclear result is not automatically submitted again.
