track motion clip

I really dig the 3D source alpha in Vegas!
For such a long time I wondered how this stuff worked, and I'm finally getting the hang of it.

here's something i made today with it.

That looks great.

Nice use of track motion and parent/child relationships! And that's just the tip of what Vegas can do . . .

That looks killer. Any chance you could screenshot your timeline and show me what's going on there?

I would have assumed that was done in something like AE.

thanks guys!

here's a short explanation for you uhrgl

here's the whole project window. You can see how everything is laid out, but it doesn't really tell you what's going on so much. First I went with the background. Make sure to make it quite large, as it's going to be panning around a lot within itself. 1440 x 960 is probably big enough. I made the background in photoshop by dragging lines around with the line tool ( took about 1 minute). looks crappy, but it gets the job done for now.

in this picture you see me about to click on the pan/crop button.

here we are inside the pan/crop window. on the timeline below you can see that i have markers set up. These allow me to move around within the background. I have it set up on the first marker and notice where the dotted box is above.

now notice where the box is as I go to the next marker on the timeline. This will give it the effect of panning across.

now that the background is ready, the next step is putting the flying objects on top. I did this by clicking on the "track motion" button.

make sure you select 3D source alpha, as you see above.

This uses the same principal I used for the background. I make markers and then manipulate the object how I wish. In the box you can see the object is slightly off center and zoomed in a bit.

when i click on the next marker you can see how the object has moved and is now flat and centered. This gives the effect of an object flying in from the right and landing in the center of the screen.

hope this helps you out, just by playing around with it you will get the hang of it.

another tip is remember to set your preview to "draft" when you're playing back the media, because it moves a lot more smooth. I switch to "best" when I want to check quality. I'm sure you probably already knew this, but just in case...:thumbsup:
