  Drift during straight position motion

  Posted by John Brookhouse on April 9, 2010 at 4:52 pm

  Hey all!

  I am at a complete loss on this one.

  I have a graphic (PSD) in PP CS4 which I want to move around the screen. It’s actually a background and larger than the program monitor so it should be able to shift around without any black showing through. HOWEVER, when I drag the image around on the program monitor in a (more or less) straight line, it doesn’t actual move in the line that I created. Specifically, it drifts anywhere from 130 pixels to 300 pixels, depending on the side. It hits the full drift right at the middle between the two keyframes (but there is no keyframe there).

  I thought this may be a glitch of moving the graphic on the program monitor so I manually programmed all of the moves into the position keyframes under video effects. It still drifts.

  As mentioned, the drifts actually happen on all sides. I can’t stress enough that there are NO keyframes at the height of the drift. There are only the keyframes that I programmed and, when the CTI hits those keyframes, the graphic is exactly where it is supposed to be.

  I’ve watched all of the motion settings while the CTI moves and the only thing changing is the “position” setting. Everything else stays the same (and has no keyframes so nothing should be changing anyway).

  Any suggestions that you could make would be greatly appreciated.

  Thanks.

  John

  Hi John,

  I don’t have access to Premiere at the moment to look up the exact terminology, but if you right-click the keyframe in the Effect Control window, in the drop down, make sure it is set to LINEAR (I think that’s what they call it). BEZIER adds curves between the points (keyframes)for a smoother path of travel and this is likely what you are experiencing.
