    88Re-encode the video and copy the audio. The output should be a similar quality as the input and will hopefully be a more manageable size.
    99{{{
    10 ffmpeg -i input -c:v libx264 -preset slow -crf 18 -c:a copy output.mkv
     10ffmpeg -i input -c:v libx264 -preset slow -crf 18 -c:a copy -pix_fmt yuv420p output.mkv

    1313Same as above, but also re-encode the audio instead of copying it:
    1414{{{
    15 ffmpeg -i input -c:v libx264 -preset slow -crf 18 -c:a libvorbis -q:a 5 output.mkv
     15ffmpeg -i input -c:v libx264 -preset slow -crf 18 -c:a libvorbis -q:a 5 -pix_fmt yuv420p output.mkv
    1616}}}
    1717
    1818Create a video with a still image (`input.png`) and an audio file (`audio.ogg`):
    1919{{{
    20 ffmpeg -loop 1 -r 2 -i input.png -i audio.ogg -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a copy -shortest output.mkv
