My Video Encoding Profiles

I use them to encode videos for YouTube and kind of archive. Videos are not that important, so they can be a bit blurry.

Currently I prefer VP9+Opus or Vorbis. Trying to evade patented codecs with crazy politics. AV-1+Opus also make sense. H264+AAC and high profile are classic.

4:4:4 subsampling is important for recordings of text, games can handle 4:2:0.

I'll just throw it there and later maybe add more info.

Kdenlive profile, easy to extract ffmpeg arguments:

<profiles version="1">
 <profile speeds="cpu-used=2;cpu-used=3;cpu-used=4;cpu-used=5;cpu-used=16" category="fhd 30fps" name="fhd30fps" extension="webm" audioqualities="7,3" defaultaudioquality="0" args="f=webm acodec=libvorbis vcodec=libvpx-vp9 vb=0 quality=good aq=%audioquality -b:v 2000k -minrate 1000k -maxrate 4000k -crf 10"/>
</profiles>

To convert extracted Blu-ray (legally bought of course) with makemkv to MKV including subtitles:

ffmpeg -i bluray:"." -analyzeduration 2147483647 -probesize 2147483647 -scodec ass -acodec flac -vcodec copy out.mkv

ffmpeg -i bluray:"." -analyzeduration 2147483647 -probesize 2147483647 -scodec copy -acodec flac -sample_fmt s16 -ar 48000 -ac 2 -compression_level 9 -vcodec av1_nvenc -movflags use_metadata_tags -map_metadata 0 -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a -map 0 out2.mkv

This probably won't work:

for i in *.m2ts; do ffmpeg -i $i -analyzeduration 2147483647 -probesize 2147483647 -scodec copy -acodec flac -vcodec copy $(basename $i .m2ts).mkv; done

for i in *.m2ts; do ffmpeg -i $i -analyzeduration 0 -probesize 5000000 -map 0 -scodec copy -acodec flac -compression_level 9 -sample_fmt s16  -vcodec copy $(basename $i .m2ts).mkv; done




for i in *.m2ts; do ffmpeg -i $i -analyzeduration 0 -probesize 5000000 -map 0 -scodec ass -acodec flac -compression_level 9 -sample_fmt s16  -vcodec av1_nvenc $(basename $i .m2ts).mkv; done

I kind of lost other profiles, will add them later.
