Keyframe Frustrations
I’m trying to loop a pan/crop animation of a still for a looping background, but Vegas’ keyframe interpolation is destroying the effect by slowly starting into the animation then speeding up — the result is that at the end when it loops back to the beginning there’s a large jump in the apparent animation speed. Not pretty.
Both keyframes at beginning and end are “linear”, and the “smoothness” is set to 0 for both. It should run through at only one speed, right?
Any ideas?

you SURE they’re both set to 0 and linear? You’re describing a non-linear action

Positive. I checked that a billion times. I also checked to make sure there wasn’t another keyframe hidden nearby.

Your not by chance viewing a previously rendered version on a new track above, are you?

No, there’s only the one video (a single picture, really) on one track.
Thinking it’s a bug in Vegas (which I surely would have run into before), I tried to put some video in front of it and behind it, then tracks above and below, but the behaviour is restricted to the single clip.
I spent a couple hours yesterday trying different things to sort it out, but nothing… Argh!
Could it be that I’m doing two different things within a keyframe — a rotate, and a zoom at once?

Not likely. If you can control the attribute, the keyframe can recall it.
Maybe you have a track muted/solo’d?
Maybe you have FX turned off in the preview window? -
Try making a totaly new project with just this event.

Tried that. The project I’m working with now is just the one single frame and two keyframes.

Try 30 frames. 1 second of video.
