Gif creation performance improvements possible? #333

Open lionleaf opened 6 years ago

The processing of gifs takes a while. I'm curious to know exactly where that time goes and if there are ways we could speed it up a bit.

Looks like the GIF is rendered in Full HD. That's pretty large for a GIF. My gut feeling is that the processing would be a lot faster if the captured frames are resized to something smaller early in the processing pipeline.

@iver56 Some dweets use 1 pixel wide lines, when you resize those, they become a mess

iver56 commented 6 years ago

I guess that depends on the image scaling algorithm. Do you have examples of such problematic dweets?

Using MediaRecorder to make .webm movies instead of gifs is probably quite a bit faster (and produces smaller files with better quality :D )

It has a bad support across browsers, mainly for Edge and Safari

BalintCsala commented 6 years ago

It would work with the GIF recorder as a fallback
