Panning Question

IndyGuy wrote on 1/29/2006, 5:45 PM
Was setting up a pan over a still photo. Just wanted to start at the bottom, go up, move right and go down. I used the the arrows to restrict the x and y movement when I sent up my pan stops. But when I play the results, it appears to pan in an arc rather than just straight up and over. This is especially annoying at the top of the still because it the photo moves down in the frame and then back up.

Anyone know why it seems to move in this manner? Is there a setting I'm missing somewhere?

Hi,

Which version of VMS are you using? If it's 6.0, could it be that you created several key frames instead of just a beginning and ending key frame?

Open up your pan crop window.

In the settings at the left, about half-way down, is a setting under "Keyframe interpolation" called "Smoothness". It defaults to 1.000. Manually set it to 0.000. Do this for all of your keyframes.

This setting, as I understand it (but I'm no expert), smooths out motion when you have more than two keyframes -- to make the motion an arc rather than strictly point-to-point motion. I was thinking that I sometimes had trouble with it even when I only had two keyframes, however. (But maybe I accidentally had three keyframes and didn't realize it.) Sometimes the pan & zoom would arc over so far as to go off the edge of the photo, even when the start and end keyframes were completely on the photo.

I really think a default value of 0.000 would be better for most people, but I don't think you can change the default setting anywhere.

another thing to try is to simply drop another transition key point just a fraction of a second to the right (or left for that matter) of the first key point with no changes. I have used this to make virtually "instantaneous" changes in transitions when I needed it. I believe it will "iron out" that arc since the points are so close together.

Thank you Tim L. That did the trick.
