Moving Text
I know I’m missing something basic here but can’t figure it out. I’ve created a Composition that is a wallpaper of text, olive green text over a 90% white background. I am moving that Composition right to left while keying an actor over the moving Composition. The text was created in After Effects. When I preview the scene or when I render the scene I am getting a double image on the text. For example, the word “CAT”…there are two “Cs”, two “As” and two “Ts”. Each letter trails slightly behind its companion letter. There also appears to be an interlacing issue. Each letter has the characteristic “venetian blind” effect. As I said, I see this effect on my computer monitor during previews and on my NTSC monitor after rendering. Is this enough info that someone might be able to point me in the right direction for correcting this problem?

Are the layers 3d and is there a light ??? Sounds like a shadow.
Also. for the interlacing, are you rendering out fields and innterpreting these fields in your NLE ????? For the previews, computer monitors don’t handle interlacing very well.

Mark thanks for the input. Pretty straight forward stuff I’m doing. No 3D, no light. I am rendering out for FCP, lower field first. Although I’ve experimented with all 3 options; off-upper and lower.
I’ve been struggling for some time now with traveling type/text horizontally and have been getting pretty poor results. I’ve done a lot of reading and much research on the subject with no positive results. One area I haven’t fully explored is the way I’m outputting to my NTSC monitor from the Blackmagic card I’m using. Perhaps there’s something in my hardware set-up that I’m missing. Again, thanks for the response.

Do you have motionblur for this layer checked on?
As for the interlacing issue, check your settings in the Decklink driver. You probably have the option ‘Single field out on pause’ checked on. Switch it off and see if this is what’s troubling you.

Thanks. Currently Motion Blur is off. I tried it with MB on but even at a 180 degree shutter angle the text was too fuzy to read, although it did camouflage the double-letter issue I’m having.
As soon as I get back in the edit suite I’ll check the “Decklink Settings”. In all honesty, that is something I’ve never done and am not sure how to go about it but it’s probably time I learned. Thanks again.
