ZOOMING IN VEGAS
I suggest you take a look at the Keyframes tutorial before you look at this on. Zooming in Vegas is great for showing a shot that is hard to see or needs to be showed slowly and more closely. Zooming is pretty easy in Vegas. With Vegas, you can do things like Zoom in, then out, or quickly in and out as in to sync with a beat of the music or a shot in the clip. Zooming is done in the 'Event Pan/Crop' properties box. In this box, you can do many things such as Picture in Picture, Shaking, Zooming in on a part of the screen and have the zoom move around the screen, etc. Much like an effect using keyframes, zooming relies on keyframes as well. So if you have a keyframe that starts as normal, and another keyframe 10 frames later than has it zoomed in 2x, then over those 10 frames, it will zoom in more and more untill its reached the end of those 10 frames and is 2x zoomed in.
1. Open your clip on the timeline of Vegas
2. Click the 'Event Pan/Crop' button on the right side of the clip on the timeline (it's right above the FX button)
3. A window will open for 'Event Pan/Crop', make sure the 'Lock aspect ratio' and 'Size about center' buttons are clicked (on the left hand toolbar of the window, its the 2nd from the bottom and 3rd from the bottom). This will keep your clip correctly orientated
4. Once you have those correct buttons pressed (I beleive they default as pressed) then you can resize the picture. Just like you would with any photo editting software, just click and hold the corner of the picture and drag it. This is where it may get confusing. Notice how when you try to size the picture down or up, you can see the grey outline of where the originally sized picture was move instead of the picture, this is the screen. So if your screen is shrunk to see only a small part of the picture, only whats in the screen will be viewable in the screen of the viewer. So if you shrink it in so that only the middle of the picture is in the grey borders of the screen, then only the middle, whats inside the grey borders, will be viewable. So shrink the screen as much as you want as the inside of the screen with be the zoomed image
5. From here, you just play with the keyframes how you want, for first time experiment, you can have a normal sized keyframe in beginning, a zoomed in one in the middle, and another normal one in the end.
Tip: to get back to normal size or for more precise zooming, you can type in the resolution on the left where it says 'Height' and 'Width'. To get back to normal, you can type '800' and '600' (or whatever your resolution is) and to get 2x, you can type in '400' and '300' (that would for .5x 800x600, you can do the math yourself for a different resolution)
6. You're done, exit out of the 'Event Pan/Crop' box and preview or render
