Pan crop problem

One of the very first things I tried to do in Movie Studio 6 doesn't seem to work right? Something that takes 3 seconds to do in Pinnacle Studio 9.3 or Adobe Premiere Elements 1 appears impossible to do.

I just want to be tightly zoomed into the right third of a still picture and pull back to reveal the entire photo. In MS6 the pullback strangely shows past the right edge of the photo??? Thus during the initial part of the reveal, a black bar appears on the right side of the screen. And instead of everything smoothly "moving" to the right, things move to the right then move back left? Neither of the other products I have tested showed this strange behavior.

The problem would appear to be that MS6 is just blindly interpolating image center & size, rather than upper left corner and lower right corner positions? Since in my case the position of the right edge of the image doesn't change from the start keyframe to the end keyframe, the "correct" result should be to leave it alone during the pullback.

Am I doing something wrong (quite possible). Or is there a way to work around the problem? Is there a way to show the curves for the interpolated parameters and modify them directly?

Hi, at the Event Pan/Crop window properties, go to Keyframe interpolation - bring down the Smoothness to 0.
HTH.

Aha! Thanks.

Seems a bit of a kludge. I did lots of these kinds of move while playing with Pinnacle & Elements without running into this issue. And those also let me change the "style"/linearity of move with impunity.

O well. I guess for a single-ended move like the one I happen to be using this doesn't matter (but i still say that MS6 is calculating the move in a "non-intuitive" way :) ).

I was having a similar problem. With pan and crop, it seemed to follow an "S-curve" (thus revealing past the edge of the photo on some pans). I stumbled onto changing the "X Center" and "Y Center" under "Rotation" for every keyframe. This makes it follow a straight path rather than an S-curve. Oddly, for me, the smoothness didn't solve this problem.

I had the same "S-curve" problem, but I found that changing smoothness to 0 gave me the result I was looking for. I think you need to be sure to change smoothness to 0 on both beginning and ending keyframes (or all relevant keyframes). Note you can also right-click on the keyframe symbol to select between linear, fast, slow, smooth, etc. I just wish it defaulted to smoothness 0 instead of 1. Maybe there's a preference setting somewhere for that?
