Video Upscaler API by Atlas Cloud
Upscale an existing video to 1080p or 2K while preserving motion, timing, and source composition. 4K support is planned for a later release.
Video Upscaler
Video Upscaler improves an existing video to a higher output resolution. Upload or provide a video URL, then choose 1080p or 2K output.
Highlights
- Video-to-video upscaling: Improve an existing clip without changing the source content.
- Two output tiers: Choose
1080pfor standard high definition or2kfor the 2560x1440 pixel tier. 4K is planned for a later release. - Source timing preserved: The workflow does not request a new target frame rate.
- Input caps: Maximum input duration is 53s for 1080p and 23s for 2K. Input fps must be 30 or lower.
- Workflow-backed output: Results are returned as playable video URLs.
Parameters
| Parameter | Required | Description |
|---|---|---|
model | Yes | Use atlascloud/video-upscaler. |
video | Yes | Input video URL. |
target_resolution | No | Output resolution: 1080p or 2k (2560x1440 pixel tier). Default: 1080p. |
Limits
The input video metadata is probed server-side before billing and processing. Requests over the duration, fps, or frame-count limit are rejected for the selected target resolution.
| Target resolution | Pixel tier | Maximum input duration | Maximum input frames |
|---|---|---|---|
| 1080p | 1920x1080 | 53 seconds | 1590 |
| 2K | 2560x1440 | 23 seconds | 690 |
Input fps must be 30 or lower. The workflow preserves source timing and does not request a new target fps.
Example Request
{ "model": "atlascloud/video-upscaler", "video": "https://static.atlascloud.ai/media/videos/af3ce4416487e61f8b299c5dc42642e3.mp4", "target_resolution": "1080p" }
Pricing
Billing matches the WaveSpeed FlashVSR public pricing model: billable seconds are the input video duration rounded up to whole seconds, with a 5 second minimum. Frame count and fps are validation limits only; they do not change the price.
| Target resolution | Unit price | 5s minimum |
|---|---|---|
| 1080p | $0.0180 / second | $0.09 |
| 2K | $0.0240 / second | $0.12 |
