Video Upscaler
FlashVSR video super-resolution: upscale an existing clip to 720p, 1080p, 2K or 4K.
Pricing: billed per second of the source video, by target resolution — 720p 0.5 / 1080p 1 / 2K 2 / 4K 4 tokens per second.
⚠️ There is no duration parameter. The source video is measured server-side and the whole clip is upscaled; the measured length (rounded up to whole seconds) is what you are charged for. Clips longer than 60 seconds are rejected rather than silently truncated.
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the result.
Headers
Body
Model name. Must be video-upscaler.
video-upscaler Source video URL. Max 60 seconds and 100MB; av1 is not supported. The whole clip is upscaled — its measured duration is the billing basis.
Target resolution. Defaults to 1080p.
720p, 1080p, 2k, 4k Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.
