I wonder how hard it would be to introduce a cut detector, so that the (to me) annoying cinematic cuts that are sometimes at the beginning or end of a quote can be trimmed off. I think a simple heuristic of something like "If the frame cuts in the last half-second of the gif, trim off the extra frames" would work well, although I don't know how well a simple detector would work, nor how many quotes have a reaction shot that would get cut off unnecessarily.
