Is there a tool or technique to control the linearity of zooms, tilts and pans in Vegas when using event pan & crop? There is a "soft landing" look that I would like to use. For example, when doing a down tilt on a photo, I would like the final part of the tilt to be slower than the first part. The result of this looks very nice. It would be nice to do this without a bunch of keyframes.

Jim, this may not be as soft a landing as you're looking for, but try using smooth keyframes rather than the linear ones (right click the keyframe to bring up parameters). They start slow and accelerate into the animation, rather than being linear, and I believe the reverse happens as the timeline approaches the next keyframe, ie you would need a smooth keyframe at the beginning and any other keyframe at the end of your sequence. (Someone might want to confirm the last part as I'm not 100%)

The first thing I do when installing Vegas is go
-Options
- Preferences
- External control and automation
- track motion default smoothness (change to ) 100
and
-Pan crop default smoothness ( change to ) 100

This is way better than the jerky movement you get with the defaults.
I leave them on linear with 100 percent smoothness which will give you as close to Bezier ease in /out as you can get in Vegas.
The smooth keyframe setting gives some pretty wacky results IMO.
hope this helps.

D. Eric Franks (from Digital Juice) does a great explanation of what the various options (smooth, slow, etc.) in the following video.
The portion I'm referring to is around the 5 min. mark but it's a great tutorial to watch and learn.

Thanks everyone for the great input. This is exactly what I was looking for. I was able to accomplish exactly what I wanted.
