Hi Product Hunt 👋 We built FastVSR because a lot of good footage is stuck at low resolution and low frame rate, and fixing it usually means a powerful local GPU, hours of setup, and guessing what the job will cost. We wanted it to be one upload, or one API call. **How it works** 1. **Upload** your video (MP4, MOV, AVI, MKV or WebM). You see the exact credit cost before you confirm. 2. **Process:** a dedicated GPU server spins up just for your job, with no shared queue. Watch progress live. 3. **Download** the result, with your original audio intact. **What you get** - 🔍 Up to 4x resolution upscaling (up to 4K resolution) - 🎞️ 2x or 4x frame interpolation for smoother motion - 🎧 Your original audio track, preserved - 📐 Transparent pricing from a published formula, so you know the cost before you commit - 🛡️ Fair billing: full refund if a job fails on our side, and if you cancel mid-job you pay only for the GPU time already used **Built for developers too** 🧑‍💻 Everything you can do in the app, you can do over our REST API. Create an API key in your dashboard, then: - Estimate the credit cost of a job before you submit it - Upload large files straight to storage with a presigned URL - Submit jobs with the upscale and interpolation settings you want - Follow progress live over Server-Sent Events, or poll the job status - Download results, list and cancel jobs, and check your credit balance The docs have copy-paste examples in cURL, Python and Go, so batch processing, CI/CD pipelines, or your own video tool built on FastVSR are a few lines of code away. Under the hood, upscaling runs on a diffusion-based video super-resolution model, and cutting-edge AI-based interpolation. Sign up to get free credits, no credit card required. We'd love to hear what you upscale first, and what you think of the quality and the API!
