Use gifsicle to assemble frames instead of ImageMagick?

[ku1ik]

Right now we assemble initial GIF file with ImageMagicks's convert and the pass it through gifsicle. convert is doing palette reduction and dithering separately for each frame. Assembling GIF directly in gifsicle may give use better quality (and maybe even smaller file size).

Unfortunately gifsicle can't directly read PNG files so we probably still need to use convert to convert PNG files into single-image GIF files before invoking gifsicle.

There may be some good tips on quality/speed in this gist: https://gist.github.com/dergachev/4627207
