Upscale your videos to 4K.
AI-based upscaling and frame interpolation on dedicated high-end GPU servers. Up to 4× resolution and 4× frame interpolation. Web dashboard and full REST API included — transparent credit pricing, 500 free credits on signup.
Cinema-quality video — without the cinema-grade compute bill.
Generate at low resolution, let FastVSR carry the rest. Restore historical footage. Smooth out frame rates. Same engine, three workflows — through a web dashboard or a REST API.
4× upscaling, up to 4K
Lift low-res footage to cinema-quality 4K. Tested on A100/H100/H200 GPUs for the highest resolutions.
4× frame interpolation
Double or quadruple your frame rate. Smooth 24/30 fps source into 60/120 fps output, alongside or independent of upscaling.
Dedicated high-end GPUs
Every job spins up its own server. No shared queues, no throttling — predictable processing time on real hardware.
Web dashboard + REST API
Drag a file into the browser, or submit jobs over a full REST API with API-key auth. The same engine powers both.
Pairs with generative video
Modern video models are expensive at native HR. Generate at lower resolution, let FastVSR carry the rest — faster, cheaper, more reliable.
Transparent credit pricing
See the exact credit cost before you submit. Full refund on our errors. Pay only for the GPU time you actually use.
Three simple steps to cinema-quality video.
Whether you use the dashboard or integrate via API, FastVSR handles the heavy lifting.
Drop your video in the dashboard or push it via the REST API. See the exact credit cost before you confirm — up to 1 GB / 60 min.
A dedicated high-end GPU server spins up for your job. Upscale up to 4×, interpolate frames up to 4×, track progress in real time.
Download your upscaled video from secure cloud storage. Full refund credited if the job fails before GPU processing begins.
"Me at the zoo" — 240p to 4K.
We upscaled the first ever YouTube video, uploaded over 20 years ago, applying FastVSR twice. The result shows what's possible for any 540p+ input.
