^ An amv by RenaSun. I've PM'ed her but I'm not sure if she'll reply as I checked her last login and she apparently hasn't been on since 2012. I've watched a few amvs with amazing masking, and I've been wondering - do amvs such as the above, involve drawing? I've been working on an amv myself that requires replacing the hair, but I can't find any footage for that, and so I was wondering - how do editors do it?
Thank you to anyone that can help me out/provide an answer!
