Within the white part of each letter there are lines, wavey lines giving the look that the font is not solid... specifically as it moves across the screen.
I set up the comp with simple defaults for NTSC DV
Font is century schoolbook
Please understand I am not intentionally holding information to make it difficult to help me...

Just out of curiosity, before beginning to work with AE did you read any tutorial manuals, such as the excellent Creating Motion Graphics with After Effects by Chris and Trish Meyer - or did you sort of just jump in, figuring "how hard can it be?"

[Reggie Spires]"Within the white part of each letter there are lines, wavey lines giving the look that the font is not solid... specifically as it moves across the screen."
A few things come to mind:
• Your white text is 100% white, and the excessive video level of the text is causing the problem.
• Your text is moving at just the right speed to make it easy to see the interlacing (if any). The proper combination of speed and frame rate can also create stuttery-looking motion.
• The text is moving slowly enough so that you're seeing AE's subpixel rendering create shades of gray at the edges of the text.
• You're looking at white text over black, which emphasizes just about any condition that's slightly off.

Thanks Dave
Always appreciate your help .. and others.. but you seem to be consistant without to insulting concerning the elementary nature of the problem.
I have been working with AE for over a year but I don't know that I have ever had this situation. Or I just ignored it.
Could you explain the first line a little more.. should my text NOT be 100% white. Also what are the excess video levels. You are welcome to point me to a source for me to learn and read rather than take your time.
As for your recomendation Joey I will look at that tutorial.. Thanks for all the help.

[Reggie Spires]"should my text NOT be 100% white. Also what are the excess video levels."
rgb has a greater range of values than television can display. if you look at 8bpc rgb it has a each color has a range between 0-255, if you converted tv's range to rgb it would be 16-235.
to correct for this, add an adjustment layer over the top of your text (and any other layers). add levels to the adjustment layer. set the output black value to 16 and the and output white to 235 (you can also use the preset 'levels - computer to video'). see if that corrects the problem.
many nle's will convert a file at import, so often you won't need to set the adjustment level, just make sure the import setting are set to correctly scale the color space from rgb to yuv (sometimes called 601).
now this would most likely only help if you are seeing a problem on a broadcast monitor or tv. if you are seeing this on a computer display, there may be another problem. there was a post the other day describing some of what you have mentioned....

This really sounds like interlacing.
Are you previewing on an NTSC monitor or your computer monitor? If your computer monitor, and you used the DV NTSC preset, that means you are looking at interlaced footage on a progressive screen - so you will see "black lines" in things that move - these are "scanlines" and will not be visible on an interlaced monitor. They are even MORE visible on computer screens with hi-contrast (white on black).
If you will be outputting to an interlaced format (NTSC DV or DVD) then try to preview on an NTSC monitor and see if there's still an issue. If you are NOT outputting to an interlaced format, I'd suggest working in a progressive comp (Ie NOT using DV preset unless you NEED it).
Any chance you could post a movie, so we can see exactly what it is you are seeing?

If you're encoding for DVD make sure that you are using an acceptable method of encoding and an acceptable bitrate. If you can encode 2-pass (or more) that would be preferable, and try a target bitrate of around 6Mbps, don't peak at more than 7.5Mbps.
Another issue you may be facing may be due to interlacing. Make sure you are not using any thin (1 pixel or less) lines as these can flicker in and out as they pass through different fields.

One last question... What are you viewing the final output with? If you're viewing a burned DVD in your computer at full screen then that's definitely the problem. If you're viewing on an LCD screen at all that can contribute as well.
How are you viewing your final output?

I am doing both. I am viewing on my computer Monitor, A NTSC monitor by way of a AJA zena card, and then burning to a DVD via ENCORE with high transcoding settings. Why would that be the problem?
