I believe Simon hit the nail on the head here. Of course everything is relative, but check out Aharon’s Video to Cartoon Podcast. The last step he takes creates that kinda stop motion jumpy effect I think you’ve described. Toward the end of part 3 (which I’ve linked to) he does exactly what Simon says.

Hey Chris,
What you are looking for is called a “Lower Third”, I haven’t found a specific tutorial for you yet, but here are some good tips you might want to take to heart…(taken from a previous post found here)
1. They don’t always have to be “Lower” consider putting them upper.
2. Based on your output consider color requirements (nothing full white or full black for broadcast)
3. Try to keep it simple and short, but leave it up on the screen long enough for folks to read, I like the 7 second rule.
4. AVOID ALL CAPS, it’s just as annoying in a lower third as it is here.
5. Avoid fonts that are thin and tall with thin serifs, they end up not displaying well.
6. Turn On your “Title Safe” and “Action Safe” Guides in your editor (AE has them as a single option in a button at the bottom of the composition window called “Choose Grid and Guide Options” ) and make sure your Lower Third is in the appropriate area.

These are just my interpretations of what is found in the original thread. Hopefully they help. Good Luck.

After doing a bit more reading, In essence we are both right, I just got my labels off.
The essence is:
-When you import as RGB it will push the Whites and Blacks together to fit into the 16-235 range for video use.
-When you import as 601 it will leave your colors alone.

Chaz is correct in that RBG = Video Colorspace and 601 = Computer Graphic Colorspace. The matte comment is one worth paying attention to, as well. Always import your mattes with 601.

I am writing this response for the original poster as much as for myself to help get this straight in my head, so please bear with me.
I consider myself a very novice user, but a quick search on google brought up a nice FAQ about this… https://xdvfaq.tripod.com/#4.12. I found it to be very descriptive. For the click impaired here is my take:
There are 2 types of color
You have Video color and Computer color:
Video color White to Black is 16-235 (601)
Computer color White to Black is 0-255 (RGB)
When you import with Avid you tell it what your source is by selecting 601 or RBG.
If you specify the source as RGB it will push the Whites and Blacks together to fit into the 16-235 range for video use
If you specify the source as 601 it will leave your colors alone (because it expects them to be already in the 16-235 range).

That’s my take, but read the linked material and compare.
If I understand it correctly,
Bars already in the 601 colorspace should be imported 601 to avoid Avid “Crushing” the colors
Bars in the RGB (standard graphics editing output) colorspace should be imported RGB so Avid can put the 0 whites and 255 blacks into the 16-235 range.
Does that sound right?
