Encoding Discussion Megathread (ffmpeg, Handbrake, AV1, etc...)

[TheDreadPirate]

How do I use ffmpeg to encode with HEVC Main10/10-bit? This parameter is supposed to work, but I know that placement within the command is important and I don't know where that is.

Code:

-profile:v main10

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg \
                -init_hw_device vaapi=va:,driver=iHD,kernel_driver=i915 \
                -init_hw_device qsv=qs@va \
                -filter_hw_device qs \
                -hwaccel qsv \
                -hwaccel_output_format qsv \
                -i "$inputFile" \
                -map 0:v \
                -map 0:a \
                -map 0:s \
                -map_chapters 0 \
                -c:v hevc_qsv \
                -preset slower \
                $hdrProfile \   <------ profile:v main10 goes here if I run my script and specify it is HDR.
                -pix_fmt nv12 \
                -c:a copy \
                -c:s copy \
                -ss $startTime \
                -to $endTime \
                -global_quality:v $quality \
                -vf "$filters" \
                "$outputFile"
