Maybe because DV NTSC is 720x480. Not 486.
I've never had such a problem with lower thirds. Not sure why you are.
> DV NTSC 720x486 4:3 interlaced
That explains it.
Yes, we are using the Matrox card and codec. Is this a problem? Are you saying the footage wouldn't have a problem if I used a different codec other than the Matrox DVCPRO one? I'll gladly switch if that will fix it, although my current project (with over 12 hours of footage) would be a huge time-sink to recapture.
Are you working in a project that is specifically set up as 720x 486 ? A normal NTSC DV project is 720x 480 and squeezing your 486 high footage into 480 could somehow be causing a field reversal issue.
The project settings are:
Editing Mode: Matrox NTSC
Timebase: 29.97 frames/second
Frame Size: 720 x 486 4:3
Pixel Aspect Ratio: D1/DV NTSC (0.9)
Fields: Lower Field First
Display Format: 30fps Drop-Frame Timecode
The video rendering is:
File Format: Matrox DVCPRO NTSC
Compressor: [NTSC] Matrox DVCPRO
Color Depth: Millions of Colors
Are there different settings I should use? Except for the lower-third problem, our videos have been fine when exported and burned to DVD.
AFAIK Matrox uses UFF and the rest of the world and neighboring planets all use LFF.
AFAIK the Matrox field order oddity is for PAL footage only. NTSC should still be Lower Field First.
Ruud is correct, as concerns DV. Also: Matrox uses 720x486 for their DV presets (D1 compatible). It does not reverse field order, as 4 lines are added to the top and 2 to the bottom.

How so "animated"? Is this a Matrox I-frame MPEG-2 + Alpha clip? If so, you should render the animation using TFF. It's really odd (and rather undocumented) but that's the way it is.

They are coming from a product called "Digital Juice" (www.digitaljuice.com). There are various ways to render them out and I've tried pretty much all of them. Image sequences with alpah, mov files with alpha, lower field first, upper field first, progressive, on and on. I've tried about every combination of ways that the Digital Juice software allows you to render them and none seem to work.
I'm going to try using just a standard Adobe DV project instead of the Matrox SD project and I'll report back if that makes any difference.
I tried creating a brand new project and using the Adobe DV 720x480 project settings. I wasn't able to use my external monitor since the Matrox break-out-box wouldn't work, so I burned a DVD and it appears that it fixed the problem.
So now I feel like I'm between a rock and a hard place in that we paid this extra money for the Matrox card and I'd like to be able to use its break-out-box features along with the real-time effects features, but if I do that I can't use the lower-thirds.
Does anyone know of anything else I could try to be able to get the Matrox project to accept the lower thirds properly?
b Problem Solved
I went to the Matrox forums and was directed to a thread there that was similar to the problem I was having. Here is an answer for anyone who is interested. It did have everything to do with the lower-third not being compatible with the Matrox project settings.
I exported a Targa Image sequence out of Digital Juice. I then right-clicked on the first image in the sequence and went to Matrox AVI + Alpha which will create a Matrox Mpeg2 I-frame + Alpha compatible AVI file (I didn't even know this utility existed, but apparently it's installed with the Matrox drivers). When I created an AVI file from the image sequence, it imported right in to my Matrox Premiere project and didn't need to be rendered. It played back perfectly and didn't cause any problems with the footage underneath.
I wish the guy I called at Matrox would have told me this solution instead of just telling me he couldn't help because Digital Juice was a third-party product.
