I wouldn't worry so much about fringing... TV and VHS recording will screw it up anyway and YouTube compression/encoding format won't see it. Secondly, we are talking a blink of an eye. A single frame of NTSC video is full of artifacts, bleed, ect. anyway so it will not be seen or much to notice anyway. Any Amiga still frame quality image is more then sufficient for TV animation. Not even the original drawings of a cartoon is perfect and crisp. They have subtle smudges/ect.
In the end, it don't mater. The artifacts /fringes are small and not much to worry.
I love to see a HAM8 video - true A1200/4000 power. Show me, boys and girls.
