Color artifacts !?
I am using some white graphic (that I created in Illustrator CS) on red animated background (it is ramp render from bright to darker red whit some bubbles moving around) and when I render out movie i get some bad results beacuse some graphic is not clean (it looks like it needs some anti-alising) and it comes out whit some pink artifacts on the edges of white graphic.
I render it as DV footage (MS DV codec for full PAL) … how to avoide that how to solve this problem?

It sounds like a low sampling/filtering quality on color channels.
It is surely because of the DV codec, as all DV codec are YUV, and 4:1:1 sampled, meaning you have only 1/4 of the data used to code color infos.
DV is well suited for real life shooting, where nothing is deeply saturated, and where you have no uniform color BG.
About filtering, it really depends of your codec. Some always filter color channels, some never do, and some others allow you to activate filtering or not.Try an uncompressed, or a RGB compressed (jpg for ex) codec to see if problem is resolved.
I guess there is no turnaround to get a clean CG picture with colored BG with a DV codec…
