Commands and notes on my use of ffmpeg (and ImageMagick, as it pertains)

ffmpeg commands

Some of these DO NOT WORK and I'm not sure why they are here ugh

ffmpeg -r 15 -f image2 -s 500x500 -pattern_type glob -i '*.png' -vcodec libx264 -crf 17 -pix_fmt yuv420p 'combined.mp4'

ffmpeg -r 3 -f image2 -pattern_type glob -i '*.png' -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -vcodec libx264 -crf 17 -pix_fmt yuv420p 'combined.mp4'

ffmpeg -r 3 -f image2 -pattern_type glob -i '*.png' -vf scale=-2:2048 -vcodec libx264 -crf 17 -pix_fmt yuv420p 'combined.mp4'
In recent days (the last 12-24 hours), there have been a couple of posts on a one
'Marak Squires', who goes by the tag JimBastard. He stands accused of stealing code,
and being a general douchebag. Stealing code isn't good. Being a douchebag isn't
acutally illegal. However, the way that the campaign against him has been carried
out worries me.
The post to reddit that brought this issue to attention was entitled 'Code Thief at
Large: Marak Squires / JimBastard'. It can be found here:
It was a link to a github gist that can be found here:

Imperfect Circles

Pleasantly imperfect spots drawn on the canvas. Imperfection created by fractal subdivision. [Updated: I forgot to close the curves with context.closePath();]

Did you ever hear about the Princess who made friends with a real live sign? The sign's name was Ice Skate and the Princess's name was Diamonds.
They decided to play a game.
The game was hide-and-seek.
Diamonds said "First you hide, then I'll find you!" "Okay!" said Ice Skate.
