What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Video enhancer for AI-generated footage
Pipe text-to-video output through the video enhancer API with scene=aigc to lift 480p / 720p clips to 1080p, 2K, or 4K. The pipeline repaints fine detail without altering motion or length.
Run an enhancementVideo enhancer for compressed UGC
Send UGC clips with scene=ugc to remove blocking, color banding, and re-encode artifacts. The video enhancer API applies smart sharpening tuned for short-form social footage.
Video enhancer for old-footage restoration
Set scene=old_film and tool_version=professional and the video enhancer API runs temporal denoise, scratch removal, deflicker, and color-cast correction in one pass — no frame-by-frame retouching pipeline.

Why reAPI
Video enhancer with 30+ algorithms
The video enhancer API analyzes each shot and dynamically composes super-resolution, denoise, deblock, sharpen, and color-enhance operators. You pick the scene preset; the system picks the algorithm chain.
Transparent video enhancer pricing
Pricing is output_seconds × tool_version × resolution_bucket × fps_tier. The video enhancer API probes your source video for the exact billable seconds before charging — no surprise bills, failed jobs refund.
Async, idempotent, callback-ready
POST returns a task ID instantly; poll /api/v1/tasks/:id or supply an event callback. client_token gives you idempotency for retries; callback_args round-trips opaque correlation data.
