The way the increments are entered? Sounds like a wild-goose chase to me. How much scaling up are you doing? Unless you're working with high-def source footage in a standard-def timeline (oh, joyful 200 per cent blowups), the image tends to fall apart after about 110 per cent or so.
Make sure you're watching on an external monitor, not the Canvas, where effects usually look worse than they are. Also, since you're using the Wireframe, make sure you didn't accidentally make other Motion changes which can further degrade the image (eg. Distort).
