Compositing Question

Hello. Long time Vegas user here (since Sonic Foundry) - mostly audio, occasional video. Currently using Vegas Pro 9.0c.

I have an opening logo with a couple of layers (background + overlay). I want to use the "page peel" FX on the logo as a transition to the main video. I'm currently doing this by rendering the logo to a single video clip and use that for the transition.

I'm thinking there really isn't any way to do this as a single step (without the intermediate render or a nested project.) So I'm asking for a reality check. Is there possibly some clever use of track compositing/parent/child features that I'm missing?

I think you could just apply the "page peel" transition to all the video tracks. The tracks don't have to all overlap anything. Just create fades on each of the video tracks that do not overlap. Make sure they match the overlap in length and apply the same "page peel" to all the fades as well as the overlap. I think this will work.

If I understand the original quesion .. yes, this will work ... you must, of course, put all those tracks above your main track .. and, of course, overlap them for the duration of the page peel only.

NOTE: I had not realized this technique would work. In the past, for similar reasons, I had used blank (empty) text boxes to overlap and give me a place to put the transition I wanted to use.

I have done this many times and it works fine. If it is the same transition and time duration you won't notice the layers.... or you could deliberately offset them for a different effect.


peace,

Thanks for the feedback. I learned a couple of things.

First is that I could put a transition on a single-sided fade. That's good to know because I've been using a zero-alpha "solid-color" media for the B-side in such situations (similar to the empty text media mentioned earlier.)

Second, using the same effect this way on multiple tracks does produce a similar result. However, in the case of a page peel the result is not identical to applying the effect to a single composited clip. This is because the page (semi-transparently) overlaps back on itself. That is additive with more than one layer compared to a single layer. (The difference is subtle and not artistically important to me.)

However, I would guess that most transition FX would work just fine in a multi-layer situation.

It would be nice if a parent track could act as a sub-mix of its children tracks (similar to a nested project.)
