H.265/HEVC 8 bit encoding error

[chlowden]

Hello I am trying to reencode PRORES 422 HQ 2336x1080 files to H.265 8bit. I have tried all the presets in High Quality H265 8 bit and I get the same error below:

Preset pass 1: -hide_banner -i <input file> -map 0:v:0? -map 0:a:0? -map_metadata -1 -map_metadata:s:v:0 -1 -metadata:s:a:0 language= -metadata:s:a:0 title= -pix_fmt yuv420p -c:v libx265 -profile:v main -preset slow -b:v 0 -cq 19 -qmin 19 -qmax 19 -x265-params pass=1 -an -sn -f null /dev/null

Codec AVOption cq (Set target quality level (0 to 51, 0 means automatic) for constant quality mode in VBR rate control) specified for output file #0 (/dev/null) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Conversion failed!

The main menu is greyed out. When I try the High Quality H265 HDR 10 bit presets, I don't get the main error but the export crashes in the last second. What I am looking for is the highest quality to smallest file ratio so I figure the H.265 8bit best for me. Do you have an idea how I can troubleshoot this? Thanks

Hello! Probably because of the 2-pass coding, try changing it to 1 pass.

Hello

Sadly, it is doing the same thing in 1 or 2 passes on the libx265

libx264 works fine. Thanks
