sudo pip install fonttools

convert to xml and back:
ttx /path/to/font.otf
ttx /path/to/font.ttx

linux:
ffmpeg -safe 0 -f concat -i <(find . -type f -name '*' -printf "file '$PWD/%p'\n" | sort) -c copy output.mkv

Merge multiple files (with same properties)

Make a text file. Contents of an example text file to repeat 4 times.

file 'input.mp4'
file 'input.mp4'
file 'input.mp4'
file 'input.mp4'

Then run ffmpeg:
ffmpeg -f concat -i list.txt -c copy output.mp4

copy dvds to mkv, without recompression

ffmpeg -i input.wav -c:a libfaac output.mp4
ffmpeg -i input.avi -c:v libx264 -c:a libfaac output.mkv

without re-encoding:
ffmpeg -i input.mp4 -c:v copy -c:a copy output.mkv

setting bitrate:
ffmpeg -i input.wav -b:a 192K out.mp3
ffmpeg -i input.avi -c:v libx264 -b:v 500K -c:a copy out.mp4

quality settings (better than with bitrate)
ffmpeg -i source.mp4 -c:v libx264 -crf 23 out.mp4

cutting video:
ffmpeg -i input.mov -ss 00:01:30 -c:v copy -c:a copy -t 00:01:30.500 output.mov

resizing:
ffmpeg -i hd-movie.mkv -c:v libx264 -s:v 854x480 -c:a copy out.mp4

marging files

generate list command prompt
(for %i in (*.mp4) do @echo file '%i') > mylist.txt

concatenate files
ffmpeg -f concat -safe 0 -i mylist.txt -c copy output
