Need Transparency around event (screenshot linked!)

Using VV4 -

Here's a screenshot to help describe the problem:

I'm doing a photo montage with 3D flyin/flyout transisitons - all events are on a single video track.

I'm using the pan/crop on each photo event - cropping "out" the photo so it appears to be floating in the middle of the screen (as a result - showing a black border around the floating picture).

I'm trying to make this black border "transparent" - so that it is not shown at all during transistions.

Anybody got an idea?

Thanks

Make sure all the images are the same size (resolution) in a program in Photoship, then in Vegas put a black picture on the bottom video layer, then rotate/pan/crop/etc. your pictures on the layers above that, and you should get what you want.

Make the stills full screen and use the track motion tool to reduce the size of the whole track.

Not all pictures will be the same resolution or aspect ratio - some photos will be landscape, others portrait. this is precisely why I want the area outside of the photo itself transparent - so during a transistion - if I "fly in" a "portrait" orientated photo on top of a "landscape" oriented photo - you won't see the black filling in the sides around the portrait photo.

some stills can't be fullscreen - they "portrait" orientated and I don't want to crop them down to "landscape oriented" to make them fill the frame.

using track motion instead of "pan/crop" on each object won't get me the affect I want - because I am going to use pan/crop feature to rotate images in differnt ways. I'd like to have this control on each object. I guess I could fiddle with track motion and use keyframing - but that would be a lot more work - and would get screwy if/when I change order/delete images from the track.

If I could just get rid of the black and make it transparent - my problems would go away. I've been offered workarounds - but does this mean that it is just not possible to do what I want to do in VV4? I'm okay with that too - I just want to know if it is possible or not. Or maybe there is yet another workaround?

Just right-click on event on the timeline, choose Properties, then Media tab, then in Alpha Channel (at the bottom) choose Premultiplied.

Use, then, *Track Motion* to make your movements, *not* Pan/Crop tool.

Is that what you want?
