I’m glad that you like the pack! I get that it might seem a little strange. The original idea was to create a package for game devs, and another for video editors. The png sequences are rendered at a higher resolution 1024x1024 and the frames for the spritesheets are 512x512 (to help with optimization). The png sequence version also contains transparent mov files. The process to create the png version of the pack was lengthy enough that it felt right to separate them.
Thanks for bringing this back to my attention, if this isn’t a format that is helpful to most developers I might have to rethink my approach.
