The quality of the output video. Allowed values: low, medium, high, maximum.
01
The noise scale to use for the generation process. Range: 0 to 1.
The target resolution to upscale to when `upscale_mode` is `target`. Allowed values: 720p, 1080p, 1440p, 2160p.
110
Upscaling factor to be used. Will multiply the dimensions with this factor when `upscale_mode` is `factor`. Range: 1 to 10.
The write mode of the output video. Allowed values: fast, balanced, small.
The mode to use for the upscale. If 'target', the upscale factor will be calculated based on the target resolution. If 'factor', the upscale factor will be used directly. Allowed values: target, factor.

API README

SeedVR2 Video Upscale

SeedVR2 video upscale restores and enlarges a video by a factor (default 2×) or to a target resolution, with temporal consistency across frames.

Billing

Billed on output video data at $0.001 per megapixel (width × height × frames). For 30fps output that is about $0.028 per second at 720p, $0.062 at 1080p, and $0.25 at 4K. The quote before submission assumes 5 seconds of 1080p at 30fps.

Failed runs are not charged.

Limits

  • Higher factors on long clips can be expensive; check the output size first.
