I think the wiggle scales down so adding it to a comp is a good idea. I also did a logo zoom the other day (I originally used the TFA logo) and I noticed how the speed is hard to get right since it’s not linear, I ended up having to do a lot of keyframes. Perhaps it would be a good idea to make the logo recede in 3D instead of just scaling it down since I assume that was originally done with a camera move as well. It was also tricky to make the logo look right as it scales down, it’s supposed to blur in a certain way, similar to the crawl.
At the moment I don’t actually remember if I scaled or did it in 3D, but honestly I’m not sure if it’d make that big a difference (probably more so for the lens effects I suppose). That does make me wonder what technique they used for the logo back in the day. Anyway, the trick, with the timing, is to use the ease functions and then mess with the curve on the graph until it’s just right (or in my case, close enough).
