Can't get a fluid pan/crop in Vegas w/key frames

[Norm Sanders]

I've tried linear, fast, slow, sharp, etc ... nothing gives a SAME speed/tempo the whole way through. In looking at the help, I understand that each one effects the pan in how it may curve around a corner or make it's path to the next point, etc.

BUT, I'm doing a LONG credit roll with a Photoshop file, and it starts out DOG slow, then picks up pace to where it's clipping along at a pretty fast rate in the middle then begins to slow down to that same dog's pace at the very end as it reaches the next/last keyframe.

I've only got two key frames ... one at the end, the other at the beginning. Both are set to linear with the other options (fast, sharp, smooth, etc.) just making it worse.

Suggestions? The only fix I can think of is to introduce a velocity envelope to it, but I'd think there's a better way to get key frames to behave the way you want them to.

On the left hand side you have the option for "Keyframe interpolation". The default is set to 1.000, just set that to 0 and you will be good to go.

Thanks, scharky, I'll give that a go!

I posted the same problem recently. Got a great tip from DSE:

You can also download a free script from the VASST site that will reset all keyframe smoothness to 0.000
Get it from: http://www.vasst.com/resource.aspx?i...f-e39c09d397d3

Hey, this is good to know... I had this same problem a while back and ended up making the "scrolled image" longer than I really wanted and letting the blank ends take up the slower part of the pan, while the middle (actual content) was in the correct speed of the pan/scroll.

You know, for many applications that smoothness works out well (i.e. panning photos in a video, etc.), but that setting to ZERO is a great tool. Not sure I'll use the script, but it's good to have around. I'll have to download it for later, thanks again!
