Activity Forums Adobe Premiere Pro Third party transitions incorrectly scaling footage

  • Third party transitions incorrectly scaling footage

    Posted by Keith Goldstein on February 20, 2013 at 1:26 am

    I am working on a PSA that is largely made up of still images. I am experiencing issues with multiple third party plugins (Boris and Coremelt, mostly) when setting up transitions. Here is the problem:

    Track 2 has an image that fills the frame. Track 1 has an image that does not fill the whole frame (pillarboxed). I want to set up a transition from V2 to V1, but during the transition, the image on V1 is stretched to fill the frame. After the transition, the image is fine.

    I seem to have fixed it in certain circumstances by nesting the image, then selecting that video track as the incoming track. (In one instance, the nest on V2 was read by the plugin as being V5, and if I tried to change the selection to V2, it kept V5 selected. If I selected V1, it switched to V4. What?)

    It also occurred with a video clip on V1. The video filled the frame, but during the transition, the video was scaled up. After the transition, it was back to 100%.

    It only seems to be a problem with plugins in which I need to select the track to transition to. The plugins that only affect the top track don’t seem to be a problem.

    Has anyone experience a problem like this before? Any advice?

    I did find a work-around, in case anyone else finds this thread with the same problem.

    Since the transitions I am using act like filters and affect the entire clip (not like the built-in Adobe transitions), the piece of the first clip that has the transition needs to be cut off the main clip and placed over the second clip, like this:

    V2: ——————–[Clip 1b]———–
    V1: –[[[[[[[[[[Clip 1a]]]]]]]]]]-[[[[[[[[[[Clip 2]]]]]]]]]]–

    That’s what was causing the issue. The second clip on V2 (Clip 2) was scaling incorrectly. In order to fix this, I removed the effect from Clip 1b, nested both Clip 1b and Clip 2, and then added the transition effect to the Clip 1b nest. This seemed to trick Premiere, and it now displays the clips properly during the transition.
