### FlashVSR

Upscale an existing video to 720p, 1080p, 2K, or 4K with FlashVSR's fast video super-resolution, which restores detail while keeping motion stable.

#### Fields

| Field | Type | Default | Notes |

You pay per second of output video: $0.014 at 720p, $0.031 at 1080p, $0.055 at 2K, and $0.124 at 4K. The quote before submission assumes 5 seconds; the final charge uses the measured length.

Failed runs are not charged.

#### Limits

- Upscaling restores detail but cannot fix heavy blur or compression artifacts completely.
