About SDR to HDR

SDR to HDR is an independent, AI-powered tool that converts standard-dynamic-range video into a true 10-bit HDR10 master. Upload a clip, and the engine remaps luminance and color frame by frame, returning a 10-bit H.265 HDR10 MP4 at the same resolution and frame rate you uploaded, with no watermark.

It exists for one specific job: taking footage that already exists in SDR and giving it the brightness headroom and 10-bit gradients an HDR screen can actually show. That covers filmmakers and editors bringing archival or client footage up to HDR10 without a re-grade, creators who want phone footage to hold up on YouTube HDR and modern TVs, and anyone with an HDR display and a library of flat-looking clips.

The service is billed per second of video with a dollar-denominated balance: top up any amount from $50, or subscribe to a plan that lowers your rate. There is no free tier and no public API; conversion happens through the web app after signing in. Payments are processed by Polar.sh as the merchant of record, which handles VAT and sales tax.

Uploads and converted outputs live in a private storage bucket and are deleted automatically after 7 days. Full detail is in the Privacy Policy. For anything else, see Contact.
