Diagnose: HDR footage looks washed out or has clipped highlights

Direct answer
HDR footage is rendered correctly only on HDR-capable screens and players. When uploaded to a non-HDR destination or rendered on a non-HDR screen, highlights clip and colors look washed out. Convert HDR to SDR (BT.709) in your editor before uploading to non-HDR destinations.
