Looks Good on Computer But Looks Bad on TV

I'm trying to get some titling that I created in Boris Graffiti onto a DVD. The titling looks fine in Boris, and also looks good in the Vegas preview and the DVDA preview, but on the TV, I'm getting strange anomilies at the corners of a custom drawn shape that's part of the titling.

The shape in question is a medium sized bold "V" shape; created in Illustrator and then exported into Boris as a PNG. It's red on a black background. The anomilies occur at the sharp corners of the "V", and consist of very small white points a few pixels big.

I even tried to draw a V shape directly in Boris, and got the same anomalies.

I've spent the better part of two days trying everything I can think of, but nothing thus far has worked.

It's a standard NTSC DV (720 x 480) file; rendered as MPEG2 (the DVDA default/no audio template)

Any suggestions?

As it so often goes, I found the solution to the problem shortly after creating this topic. And since people come here for answers, I figured the least I could do was post the solution...

The problem was due to the fact that red does not translate well on a black background. I found this out by adding some text in Vegas; using the same color red as the "V" shape. My Vegas text usually looks very good on the TV, but not this time. I had those same white anomalies all throughout the text.

I did a web search on this, and to my surprise, I found a great deal of information that more or less states that red is the worst color to use with video. It looks like it's time to redesign my titling.

Hopefully this post will save someone else from the frustration that I went thru.

DV video uses 4:1:1 "chroma subsampling." That is very bad for solid colors. Rendering to 4:2:0 MPEG-2 does it no additional good. Do a search on the Vegas Pro forum for a wealth of information.

Here is a post with an example picture of what you are talking about:
