I see what you mean about the quality/variety of GIFs really not being up to the same standard as traditional clipping would provide, but I also agree that this particular vidder did an amazing job with what she had!

I don't have the first clue how to make GIFs so I don't know how time-consuming of a process it is...If it's pretty intensive, I could see how some GIF makers would be really offended by someone snagging their GIFs to make vids without their permission. Although it seems the tumblr community is a lot more lax about that sort of thing. I see vids/fanart reblogged all the time without any credit being given to the original creators.
