EDIT2: FIXED.

EDIT: It appears Vegas just shits hard when you reverse a clip, and then mask it.  This is a sad discovery since I can't seem to fix it, as it means some animation segments won't be usable as a masked animation.  I know a way to get around it, but it'll be a bit time consuming.  Luckly, Twilight and whatever the hell the spinning pony's name is are usable and will be appearing in a later project.  Rarity's already in my current project, so expect to see her again soon.

So yeah, I was randomly masking stuff for practice instead of working on the PMV I should be doing.  Notice what happens?  The masking lags out and goes to shit, despite being nothing but a copy/paste of the original, perfectly masked clip.  Vegas?  BIG FAT FUCK YOU.

If someone actually knows how to fix this, pony up (hurr) and tell me.  I've tried just about everything, and the damn rage level with me and vegas right now is epic.

I was going to keep screwing with this and fix it, but mumble insisted I upload it completely fucked up...and who am I to bitch?
