Redo the map at 29.97, rather than stretching it out, which interpolates new frames and causes blurriness.
Thanks Jim for your suggestion but I would be going from 219 images to thousands of images and the animation of the key map doesn't need to be so detailed.
Since my key map rendered out fine by itself, I re-did my #1 trial from above but this time exporting it as an uncompressed AVI. The results once placed over the main clip aren't perfect, its still a little blurry from rendering twice and still getting interpolation lines but its much better then before/acceptable for its use.
Thank you again Jim for your response I did some searching around on Interpolation and am just a little bit more aware then I was before

Yep. That's the way it's done.
