Convert video files to MP4 through FFMPEG

ffmpeg.md

This is my personal list of functions that I wrote for converting mov files to mp4!

Explanations

-codec:a (audio codec) : libfaac, libfdk_aac, libvorbis

-quality : best, good, realtime

-b:a (audio bitrate) : 128k, 192k, 256k, 320k

-codec:v (video codec) : mpeg4, libx264, libvpx-vp9

-b:v (video bitrate) : 1000, 2500, 5000, 8000

-vf scale (resize video) : -1:X (where X is height)

-qmin 10 -qmax 42 : I don't really know what is this for, help related to this is welcome...
