Track Matte problems
Hi all. I’m having trouble adapting to Premiere Pro 7.0.
Three tracks. Composition is 640×480.
Track 3: Black & white animated AVI 640×480 which is my mask, scale=100%
Track 2: image 1, 800×600 still image, inverted, shifted vertical a few pixels, track matte keyed to luminance of track 3, scale is to fit (72%)
Track 1: image 1, 800×600 still image, scale is to fit (72%)Here is a screenshot of the result:
https://www.pbase.com/eric_s/image/41879038/original.jpgIf you can’t tell, the track matte appears to be scalled smaller and also not centered vertically. (The moire effect is my track matte, not the problem or compression.) I’ve tried this on other stills of stranger aspects (such as 1:1) and the track matte shrinks itself to something like 20% width and height of the composition, offset by 100 pixels in both axes (not centered). Now, if I use a 640×480 clip for both track 1 and track 2, the track matte behaves correctly.
As far as I can tell, this is a bug in Premiere Pro (7.0). A very _LARGE_ bug. A show-stopper for me, in fact. I NEED this effect. Premiere 6 handles this job just fine (without the need for a hidden extra track too), however there’s a strange bug with Premiere 6 that cropped up recently on my system that renders everything black no matter what I do. I’m considering moving over to Sony’s Vegas 5 because of this. Pre-rendering this effect in AfterEffects is not an option, because I have to use this effect often and I need to be flexible as to which pictures I apply this effect to.
Pleading for help!

I can’t seem to make your link work…
In PPro, your track matte will take on the scaling and position attributes of your key source (whatever you do to track 2 gets done to the matte on v3). It sounds like this may be a part of the issue.
Can you describe what settings you’re using in the track matte keyer please?

Tim, I think you’re spot on. My track matte is 640×480, but the source is larger. Is there any way to UNLINK this relationship? It’s not intuitive why it’s linked in the first place. The alternative is to scale down my source imagery to the project dimensions in Photoshop, which is prohibitively complicated, especially if I want to zoom in on a region (at which point I’m back to Premiere 6 and it’s motion). The majority of my sources are still photos.
The link… should work but the host is being flaky. Try this: https://www.pbase.com/eric_s/image/41879038

Is this not an issue of different PAR’s between Photoshop and PremPro projects.

It’s sort of a matter of philosophy. Before if you wanted the matte and the key source to move in unison, you had to copy/paste the motion settings…which is extra steps if that’s the task at hand. You want to move the track matte separate of the key source, so the current system seems like extra steps. I think it’s all in what you’re used to…
The track matte needs to move on another sequence, then use the sequence as the matte. That’s the workflow model now. If your matte is moving differently on every shot, I suppose this seems like extra work, but the person who needs several repeating moves would love it as you just keep dropping the sequence in…
On the disabled track thing…what I DO like is that now the matte can be on any track so I can move my mattes to a very high track and simply work with footage below. With the track disabled, if the video track below it doesn’t have the track matte key applied, I can leave the matte up there and it doesn’t bother anything.
…as I said, it’s sort of a matter of what you’re doing at the moment as to whether the programmers were geniuses or goats…I have days when I have both viewpoints…

wow. 10 years later and they still haven’t added a simple checkbox to unlink it? definitively goats. it’s just a nuisance.
