Video Upscaler — AI-Powered 4K Enhancement with SeedVR2
Improve resolution and restore detail up to 4K across every frame. Access SeedVR2 and the standard upscaler through a single API with zero cold starts.
AI Video Upscaling Quality
Turn soft, compressed footage into sharper output without building your own enhancement pipeline. WaveSpeed runs inference on your video through a fast API.
Edge Definition
Sharpens text overlays, product outlines, and hard boundaries. AI models detect and enhance edges frame-by-frame for crisp, professional output across the entire clip.
Texture Recovery
Restores fabric, skin, and fine surface detail that compression had degraded. The upscaler rebuilds high-frequency information lost during encoding.
Artifact Reduction
Removes block noise and banding from MPEG and H.264 encoding. SeedVR2 processes frames with temporal awareness for stable, flicker-free results.

FAQ
SeedVR2 processes frames with temporal awareness, so it knows what came before and after each frame. That keeps motion more stable and textures more consistent across the full clip. The standard upscaler runs faster and costs significantly less per second, making it the practical choice for batch work where peak motion quality is not the priority.
720p, 1080p, 2K, and 4K. Set target_resolution in your API request. Both models support all four options.
Yes. Diffusion models typically output at 480p or 720p with slightly unstable motion. SeedVR2's temporal logic is designed to help stabilize that while upscaling, so the result tends to be cleaner than you might expect from synthetic source material.
Set copy_audio: true and the audio track passes through untouched. Timing, sync, and encoding stay exactly as they were in the source file.
10 minutes. For longer content, split into segments, process in parallel, and merge afterward.
No. WaveSpeed hosts both models on optimized infrastructure. Send a request, get a result. Nothing to provision, nothing to maintain.
Match your delivery spec. 1080p at $0.025 per 5 seconds covers most web and social publishing. Go to 4K for large-format display or archival output you will reuse.
