Mmm I can't really tell any difference in image quality, but I don't use filters alot so I wouldn't know. Just so you know, I only had 1 frame for the first one and you can read it fine, no? You just have to edit the frame times. (3 seconds for that one)
Also if you're using a lot of frames (over 50) than it causes distortion on slower PCs (Like mine.. 1.2ghz and I see chunks in the GIF)
