The .7z extension indicates it is compressed using the 7-Zip LZMA algorithm, which is preferred in technical communities for its high compression ratio, making large video datasets easier to share and store.
In communities like those found on Doom9 or various encoding Discords, this dataset helps establish the "best" settings for public releases. Technical Context anime_comp.7z

Anime often features large areas of uniform color. Standard compression can create "banding" artifacts here, where smooth gradients turn into blocky steps. anime_comp.7z
