Will it ever go back to its previous 350mb size again??

Why are you asking them it's up to crunchy.

I hate the way the size keeps going up... it is almost at the point where I'll see if I can re-encode it and get a more desirable size without mangling the quality too much(too much being the keywords). 10 shows are fine in this size, but when you have upwards of 100 shows on your drive it begins to get ridiculous. Have 7 terabytes of anime already.

Managed to get the size to around 300MB per episode without a noticeable change. Anime has wide areas in the same color, compressing that without a loss in quality is fairly easy. I also burned the subs into the file instead of having them in a container. This makes it easier for some players to display the *.ass subs. Basically.. Think of Crunchyroll going more towards what a BMP is like, while I'm hoping to get closer to a PNG. An exaggeration, but both are lossless, BMP is just uncompressed.
