ALRIGHTY. So I made this by request from one of my followers on my Roosterteeth blog.
A couple of quick notes to add to this:
-Typically gifs made this way should be 50 frames or less. You can make them with more than 50, but the more frames there are, the larger the file will be and you’ll have to sacrifice size and quality for length.
-I usually make my gifs with a width of 400 pixels or less. Again, you can make yours larger than that but it will significantly increase the file size.
-Tumblr is very picky about gif size. I’m not actually sure what the size limit is, but I’ve never been able to get a gif over 2mb to upload. So if you seem to be having issues uploading something, either shorten the gif, decrease the size, or lower the quality through the “colors” option while saving. Sometimes a combination of the three will be necessary.
So there ya go!
