Supported resolutions
| Tier | Shorter side of the frame | Per minute |
|---|---|---|
| SD | up to 480 px | $0.05 |
| 720p | 481 to 720 px | $0.08 |
| 1080p | 721 to 2159 px | $0.15 |
| 4K | 2160 px (up to 3840×2160) | $0.40 |
The tier is set by the shorter side of the frame, so a vertical video is billed like its landscape equivalent. Videos larger than 3840×2160 are not accepted.
4K prices by duration
| Duration | Price |
|---|---|
| 10 minutes | $4.00 |
| 30 minutes | $12.00 |
| 60 minutes | $24.00 |
| 120 minutes | $44.40 |
A 4K frame has far more pixels to reconstruct than an SD frame, so it takes more GPU processing time.
Before you upload
- Formats: MP4, MOV, AVI, MKV or WebM.
- Keep the original file: re-encoding it to save space removes detail the AI relies on.
- 4K files are large: keep the page open until the upload is complete.
Frequently Asked Questions
Is the output really 4K?
Yes. The processed video is delivered at the resolution of your source file, in MP4 (H.264).
What is the maximum resolution?
4K UHD: 3840×2160, in landscape or portrait. Larger videos are not accepted; downscale them to 4K before uploading.
Is my video kept private?
Source files are deleted once processing completes, processed videos 7 days later, and uploads are never used to train AI models.
