Why does certain colored text look so rough and jagged?
I’ve almost been tearing my hair out over this one: I tried look around for answers elsewhere but I haven’t a solution to this yet.
When I create a new video track and Insert Text Media, the initial white text looks very smooth in my output. So does yellow — this includes if I use the Draw Outline special effect. But, if I change the color to something like hot pink (RGB of 255, 0, 128), then the antialiasing appears noticeably rough in the final rendered output.
Any idea why this is? It’s pretty weird and doesn’t make a lot of sense because all I did was change the colors. Here’s what it looks like to me

I don’t have an answer for you, but I have noticed the same thing with projects I used to do in Adobe Premiere 6.5 — white looked fine, red looked jagged.
I’d be as interested as you are in finding out why — or better yet, how to fix that.

Welcome to the wonderful world of Video, DV, color spaces and all of that, I think. My understanding is that his is a result of the limited color space of DV etc, and it gets particularly problematic when you go from DV to DVD.
This article describes some of this: https://xyhd.tv/2006/11/technical/shooting-for-hd-why-color-space-matters/
Not sure how you can get around this.

Thanks Terle that does help some but doesn’t quite explain why I run into these problems when I’m outputting my video to be viewed on computers. I’m not burning it to DVD or anything, and haven’t done any color conversions (that I know of) so if it’s Vegas doing something funny in the process, I’d like to disable that.

you’re always going to run into this problem with highly compressed formats. DV is bad, more highly compressed is worse.
If you want the mathematical reasons, i suggest Charle’s Poynter’s excellent book on HD. Read the chapters on compressions and color space.Douglas Spotted Eagle

The article is equally valid for video output on computer and TV. This is a problem with compressed video no matter what output. DV is compressed, and I assume you are working with DV.
There are options, but you will probably have to chose colors when titling carefully.
