Export HDR video (HDR10 and HLG)

HDR10 and HLG, encoded from float frames

HDR delivery needs more than a tag on an SDR file. Premation draws HDR exports into a half-float surface without clipping at white, converts to BT.2020, and encodes 10-bit HEVC with the PQ or HLG transfer.

How to do it

  1. 01

    Decide between HDR10 and HLG

    HDR10 uses the PQ curve with static metadata and suits streaming and HDR displays. HLG is the broadcast choice and degrades gracefully on SDR screens.

  2. 02

    Check your ffmpeg

    Both formats need an ffmpeg with the libx265 encoder. Without it the export falls back to H.264 High 10 and says so.

  3. 03

    Pick the format in Export

    File ▸ Export, then HDR10 or HLG. An HDR export overrides the project's viewer transform, so a preview transform is never applied twice.

  4. 04

    Queue it and check on an HDR display

    The result is an MP4. Working-space white is placed at 203 nits and the picture is clipped at a 1000-nit mastering display, so judge the highlights on a real HDR screen.

Questions

Can an HDR export have a transparent background?
No. An HDR delivery is opaque. For alpha with high precision use ProRes 4444 or an EXR sequence.
Does it support Dolby Vision?
No. The two HDR formats are HDR10 and HLG.
Can I render HDR from the command line?
Yes. premation render with --format hdr10 or --format hlg writes the same 10-bit HEVC file.
