Pixelated Lines

[nanoreactor]

Hi everyone. long time reader, first time poster ( haha i always wanted to say that)

I animate. and can burn my cartoons directly from my comp to DVD. But i have a quality issue, i read for a while and didnt see this question answered, I use DVD workshop by Ulead. and it says its encoding at 8000 kbs. I think thats as high as youd want to go with your DVD's but when i watch the animation on TV.. the lines are crystal clear when theyre still. but when a line is moving it looks all pixelated. I dont see this problem on professional DVD's nearly as badly. what am i doing wrong?

Is the effect more visible when a scene pan's or moves?

In that case it could be the resize/rescale filter.
If the original animation frames/pictures aren't similar to the DVD resolutions (720*576 for PAL, 720*480 for NTSC) the program needs to resize them. If you resize without a proper filter you'll get blocky/pixalated lines, most visible in movement and not so much in stills.

EDIT: Red your post again... sounds more like a problem with the MPEG-encoder/limitation in the MPEG2-specification.
The "IBBPBBPBBP"-order that MPEG2 uses, gives only 1 fully encoded frame every 12 frame, giving you less detail in the frames inbetween, especially in sharp areas of the picture. (Cartoons are all sharp all the time)

horizontal lines that are slightly off perfectly horizontal look the worst. but lines that are almost vertical and vertical look good. someone somewhere else mentioned frame rate of the source .avi vs. the mpeg, i think my source .avi are exactly 30 fps.. not the 29.97 they're supposed to be. could this be the problem?
