I'm not sure how excessive that is. From my perspective with a lot of movement in most of the scenes, shifts in scenes, 100% dither, and being a bit on the larger resolution end for a gif (imo), I don't know how much you could actually save in space without having to lower dither (lowering image quality) and/or cut in resolution size. Maybe at best could save around 0.5mb without tampering with the dither and resolution through cutting out stationary/background redundancy amongst some frames.
Dotsu said: I don't remember this scene at all. I tried SauceNAO on a few frames, with no hits. Anyone know what episode it was?
Sorry for not specifying the source, but it's indeed what Moebius Strip said, it's from episode 13 which was released some months after. Around the 5:30 mark.
