I don't create art, but sometimes I piece things together to make a desktop background.
Death Note Minimal, L and Misa
One of my few ships. The characters hover above the baseline to provide room for for the taskbar on screen computer it's targeted at.
It's a little-known fact that GIFs are older than even the transistor. Sequential art frames with poor color depth and bad aspect ratios have been found etched on the walls of tombs in Egyptian Pyramids. Not surprisingly, they were usually about cats.
I generally extract video segments and turn them into an image sequence with ffmpeg, then combine them with ImageMagick. For example:
$ ffmpeg -i input.mp4 -ss HH:MM:SS -t HH:MM:SS -acodec copy -vcodec copy clip.mp4 # Extract clip using timestamp. $ ffmpeg -i clip.mp4 -vf scale=512:-1 -r 10 frames/ffout%03d.png # 512px wide, scaled height. 10 frame/sec $ convert -delay 10 -loop 0 frames/ffout*.png output.gif # .1s between frames, infinite loop
