Ah, you mean to use "level" with hyphen, so "-level". This is poorly described. But how to determine, if such option is meant for audio, video or both? > I think its name is the only practical explanation of its meaning, as I > mentioned, it can be completely different for each codec. Well, saying "Set the level option of the codec." IMHO would not be superfluous. Also "codec-specific" would be better than "unknown". In another option set of K9copy there is: -b $VIDBRk -s $WIDTHx$HEIGHT -vf crop=$WIDTH-$CROPRIGHT-$CROPLEFT:$HEIGHT-$CROPTOP-$CROPBOTTOM:$CROPLEFT:$CROPTOP -aspect $ASPECT -codec:v libx264 -level 30 -flags +loop+mv4 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 -me_method hex -subq 7 -trellis 1 -refs 5 -bf 3 -b-pyramid normal -weightb 1 -mixed-refs 1 -8x8dct 1 -coder 1 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -pass $PASS -passlogfile $PASSLOGFILE Shouldn't it be "-flags pass1" instead "-pass 1"? Are there other elements in that option set, which are bad syntax? E.g. for -cmp I only see values like 'sad' in the ffmpeg docs, but not '256'. -Ulf _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
