So I have Flash now! And I decided to remake my channel intro with it. Now it's much cleaner.
The old one was made with Gimp, and the frames were transported into Anim8or in order to zoom in on the animation. Since the frames were rasterized, it got blurry and pixelated as it zoomed in, and the fade to black on the flag transition looked awful. Now it's fixed.
The music is an edited clip of the song "Celtic Dawn" by Barry Fasman and Eric Rigler. The sound clip used is less than 6 seconds long, has been edited, is not the "heart of the song", is not going to harm sales of the actual song, and is not the main focus of the video, which should qualify under fair use.
