The output will show jerk, then wonderful person since echo parses the \b character.

echo "You can have a bit more realistic typing with some shell magic." | pv -qL $[10+(-2 + RANDOM%5)]
echo "pretty realistic virtual typing" | randtype -m 4

Convert those .mov files that your digital camera makes to .avi

Adjust the bitrate (-b) to get the appropriate file size. A larger bitrate produces a larger (higher quality) .avi file and smaller bitrate produces a smaller (lower quality) .avi file.

Requires ffmpeg (see man page for details)

(tested with canon camera MOV files)

Other examples:

ffmpeg -i input.mov -sameq -vcodec msmpeg4v2 -acodec pcm_u8 output.avi ffmpeg -i input.mov -b 1024k -vcodec msmpeg4v2 -acodec pcm_u8 output.avi
