When using the text tracking tools in Motion 4, the expansion is not smooth. Often I interpolate between 1 and 4 over the course of 10 seconds. It's smooth in livetype but not so in Motion. It also doesn't matter if I'm working with a text behavior or doing the keyframing manually.
I'm working in DVCProHD most often at best resolution, but the problem also occurs in animation codec and others.

Yes, this drives me insane -- has for years. What I think I've discovered is that this bejigeddiness is linked to "centered" arrangement. That is, if you switch to Flush Left arrangement, the animated text tracking becomes smooth. My theory is that Motion is having a tough time animating text tracking WHILE also constantly re-centering the text.
I wish I had a solution for this. But maybe this extra clue will put us one step closer to a cure!
