Change the speed of the GIF

[sindresorhus]

A few people have requested this over email and some other GIF tools have this too.

This issue requires you to have advanced Swift knowledge. It's not an easy beginner issue.

Would be super useful for me

I can imagine a very lengthy screen recording that would benefit from speeding up, or the opposite… making the interaction/animation slower to better make a point. So it's not a bad idea at all!

I usually need to speed up gifs I make for Twitter/GitHub (example). Currently I use ffmpeg as an intermediate step, but it would be super nice to have the option directly in Gifski.

I recently also had the case I wanted to share a relatively lengthy screen recording. To speed things up and save frames (hence file size), I wanted to speed the GIF up by 2×. Speeding the video up was better in this case compared to lower the frame rate to something like 5-10 fps. I ended up converting the video with Compressor and then created the GIF with Gifski.

This is now "PR welcome".

The feature should be fully in SwiftUI and be embedded in the Storyboard using a NSHostingView.
