i'm comfortable using ffmpeg, i just wish people would share their secret formulas that can:

    - take a video of varying format (mov, mp4, webm, mkv)
    - give it the desired output resolution
    - give it the desired output quality preset (simple will do - hi, med, low)
    - output resulting file(s)
    - do it fast

i have a giant shell script of ffmpeg commands i've used in the past, but i have to stop myself from getting sucked in to trying to understand the whole process and losing a whole day at work
