Topic: HDR SVP Code MPV64

Hi SVP Team,
Transcoding (4k) HDR .265 to .264-60FPS video results in the HDR > SDR filter not working or breaking in mpv64. Can this be fixed some point soon or is this just a limitation of the HDR>SDR conversion protocol?
Thank you

Re: HDR SVP Code MPV64

Every 4k video I have now comes in HDR this makes a big difference / disadvantage (to 60FPS > SDR HDR.264 playback conversion Breaking using SVP).

It is a bummer. Thank you
Otherwise happy with SVP Code
Thank you
