Gif would be fairly short. Longest Gif ive seen was like a minute. What would be a good idea would be to take a bunch of Gif’s and stitch them together in a video format and people script that. Then they could use @Lucifie’s HandyControl’s Chapters system, which i think is currently under used. Alot of Hentai Gif’s i see both come in .GIF and as a mp4 in another link. Just my 2 vents.
