Crawl perfect in FCE4, jittery on export

Question

Hi-
I'm creating crawls over Hi Res photos in FCE4 that are smooth in my Canvas but when I export them to .mov there's a slight jitter.  I've tried just about every export parameter and still no change.  I've also tried viewing the export in Quicktime Player, VLC and even tried burning to a DVD with Toast.  All exhibit the same problem.
Thanks for the help!

Creating crawl in Live Type, then tried Boris plug in

Answer 1

The jitter in the lettering is due to the interlaced nature of the video.  It generally does not appear in the Canvas but does in the finished video.
There's not much you can do about it in FCE other than use a larger font size, and even that is not going to completely eliminate it.
In Boris Title Crawl there is a control called 1:2:1 Deflicker - try checking it and it may help decrease the amount of jitter, but it will not eliminate it.
