I have an h265 mp4 HDR Main10 movie file. I am editing in Premiere Pro 2020 version. When I export with Voukoder, regardless levels (0-255 vs 16-235) or constant luminance or NCL, and I am exporting with 10-bit turned on in the Bt2020 color space, when playing back these files on an HDR TV the whites are WAY blown out. It's rather horrible. If I export with Premiere's builtin h265 exporter using Main10 settings, the video comes out looking pristine. I can provide you with the source mp4 file if necessary but it is ~50GB so will take some coordination.
My question is, have you edited true 10bit HDR BT2020 files and exported with Voukoder AND played back on an HDR TV? Vouk is passing HDR metadata to the TV (ie the TV "knows" it's getting an HDR stream e.g.).
Hope this makes sense. In short, I do not think Voukoder is exporting and handling HDR source files correctly. I am aware HDR is a work in progress in premiere, but premiere on its own handles these exports in a predictable and proper manner.
Also on another note--do you think Vouk is "over amping" or "over normalizing" Ac3 and EAC3 audio on export? It sounds very very loud when bitstreaming to receivers/TVs.
thanks in advance
