Wait, isn't that more of a criticism of the "shooting in" part, not the "bouncy" part? You would have more time to read the text if it wasn't flying across the screen. Or does the wobbliness itself make it less legible?
Letting the text be static for more than a split of a second before the gif starts over would no doubt help with legibility
I do try to do that as much as possible. Like with this one:
But the problem with making GIFs out of 30 Rock is that the dialog is so quick. The camera often cuts to the next character immediately as a character finishes their line, so I can't really keep the text onscreen for as long as I'd like. That Bucky Bright scene is an exception, because the slow pacing is really part of the joke.
So that probably just makes it that much more important to not waste precious screentime on transitions.
