@david-tu -- Appreciate reply. I vaguely remember someone mentioning this to me here a few years ago. I purposely default preferences for Pan/Crop at 100%. Maybe I'm incorrectly assuming that means what it implies (the smoothest). So let me ask you this:

---- What do lower numbers (incl. to 0) settings do to a keyframe's behavior in comparison to higher ones (inc. to 100)?

---- And for this particular simple 3-keyframe example, what numbers would you use?

Keyframe 1 @ ?% - Type of keyframe = ?
Keyframe 1 @ ?% - Type of keyframe = ?
Keyframe 1 @ ?% - Type of keyframe = ?

---- I tend to use Linear mostly. Should there be some mix-and-match here that would also help?

Thanks.

Those numbers affect all modes of linear and smooth. Generally they adjust the speed up and slow down at the beginning and ending of moves. Honestly, you have to play with them to see the effect since it varies based on the other settings. Linear attempts to give you a hard stop and start where smooth tries to ramp up and down.

The first is all linear at 100, the second is all smooth at 100 and the third is all linear at 0. I think the first works best, but I don't know if this is the movement you are going for.

Thanks for what seems to be the time you took to do this. And I agree - the first one is the smoothest. The nit-picky part of me wants to have a kind of "beauty pass" no stop affect. Probably only possible in Adobe AE. Which I have (CS3) but have essentially never really used since I'm Vegas-addicted. :) Anyway, I can fiddle around with the smoothness numbers, see what happens. NRN.

Thanks for suggestion - I checked it out and definitely has some cool features I saw in the demo video. But as some of the Vegas veterans here know, I live on a fixed Soc. Sec. disability income only, am a "serious amateur/semi-pro" - not a pro - and so out of my wallet zipcode. One has to get the entire Vegasaur to get this fx. Been aware of Vegasaur for a long time - but wallet outweighs need for cool stuff (like this fx) - lol.

It seems to me that there used to be a PATH line in pan/crop (maybe version 4) that you could use bezier curves on. It just disappeared one version and I am not sure why.

I started with v.6, so if there was... I missed it. :)
I know one veteran here who seems to have connection with Magix, maybe we could hustle them to put it back in. Or as a downloadable script or such. Retro-adaptable to, oh, say version 10. (Yeah, dream on, dude.)

The PATH feature was extremely useful. I never could understand why it was dropped. This has been an interesting discussion. Thanks.

The path feature just showed the path, never modifiable. I miss it & remember being told years ago it was unintentionally removed in Vegas 5 (along with some other features!) and would come back (other features removed, like the track motion presets, came back).

In the Vegas help file, search for "keyframe", click the "keyframe animation" listing, scroll down to the "Change the interpolation curve between keyframes" and expand it. It will show the curve each keyframe uses.

The speed is changed by spacing the keyframes closer (faster) or farther (slower) apart. The curve type you use on the keyframe also changes between that keyframe & the next keyframe. That's important to remember. The curves affect the speed somewhat, but not as much as the distance between the keyframes (also remember, the higher the FPS the more frames you need between them to make it slower)

Using more keyframes may be what you want.

I was thinking you could modify the path, but memory might be flawed. I did think it was a useful visual indication making it easier to adjust your positioning.
