When posting an answer it's common to want to illustrate an idea using an animated diagram or screen capture. I have some screen capture software (iShowU) but it doesn't have and export to GIF option built in. I also know of a website for quickly creating animated GIFs from an image sequence (gifmaker.me), but I have to crop in an image editor and export the frames first, so it's not very efficient.
Are there any apps or web apps you guys recommend for preparing an animated GIF quickly from what's on the screen?
Attention: This post is not specific to one software title or website!
I'm looking for something that will work on a Mac, but this conversation is intended to invite discussion of options for all OSes that Blender can run on (Mac/Linux/Windows).
Thanks!
