We have researched various platforms to determine which outputs are compatible with Frame.io's HDR support. While we researched common workflows, this list is not exhaustive.

For a file to playback in HDR on Frame.io, it needs to:

  • Be Rec.2020 or P3D65
  • Have an ST.2084 (PQ) transfer function (or EOTF)
  • Have its color primaries defined; these need to be carried in metadata flags in the uploaded asset

What HDR support means here is that the files are flagged as BT.2020 PQ, and so the uploaded files can be recognized by Frame.io as HDR and thus be correctly encoded for HDR playback. If you have files from other platforms not on this list, a good idea is to read the metadata using the fantastic free software Mediainfo from MediaArea and check these values:

  • Color primaries = BT.2020 or P3-D65
  • Transfer characteristics = PQ or ST.2084

💡 Pro Tip:
While H264 is an 8bit format, there are cases where having a lo-fi proxy (which renders faster) is useful. Because H264 does carry the metadata flags and encoding properly, it can be a useful tool to quickly share HDR content for review when color accuracy is not the primary concern.

Please note: HDR assets uploaded previous to the release of HDR support will not playback in HDR. Please upload these assets again to see them playback in HDR.
