Ubuntu Multimedia Bash Tricks

Below is a listing of the common commands I use to perform certain MultiMedia based encodings, conversions, whatever.  I plan on adding to this post from time to time, make alterations and other updates.  It's pretty much a living document.  All of these commands give (me) great results for what I'm looking to do.  There are probably "better" ways, and probably even GUI-based applications that will do these.  However, using scripts or reptivitive actions, these could come in hand.
