_{^{a quick conversion trick to optimise gif filesize using temp transparency
# convert 8 bit rgba .tiff's to 256 colorspace gifs (alpha to rgb black)
ffmpeg -framerate 50 -i %04d.tif -loop 0 output.gif
# we now replace the exact black and introduce a new background color — this is much more efficient than preserving a flat color from the original output
gifsicle -U --disposal=previous --change-color="#000000" "#FCD137" -O2 output.gif > output_gifsicle.gif}}
