I have been trying to use VTCompressionSession to compress an HDR video recorded on iPhone - but it comes out as very "washed out". I tried using HEVC codec as well, but that still gives me the same result.
Any ideas on how to do this?

Use this as the codec in VTCompressionSessionCreate? – user3500462 Mar 01 '22 at 23:29
