Keyframes are quite possibly the most useful tool in the Vegas program. What is a keyframe, you ask? A keyframe is simply a marker where you can set an editing feature such as Zoom, Crop, Black and White, pretty much any effect out there.
I'll demonstrate using keyframes to zoom, but the principle is the same no matter what effect you use.
For the clip you want to zoom on, select the "Video event pan/crop" option. The image below has necessary options circled.
For zooming in, place the cursor on the timeline where you want to begin the zoom. Note that the timeline is reflective of the clip time, not the timeline for the whole project. If the clip has been shortened, the timeline reflects only the amount of the clip used in the project. Once you have the cursor where you wish to begin the zoom, select the "Add keyframe" button, which is a plus sign. If you have placed a keyframe in the wrong place, you can click and drag it. Since this is the starting keyframe, you don't have to change any of the options.
Next, move the cursor to where you wish to finish the zoom and insert another keyframe. Since this is where you wish to end the zoom, you will need to resize the zoom window. Ensure the maintain aspect ratio button is depressed. As you can see above, I changed the center of the zoom so that it zooms in on the person. The preview window in the lower right will show you what the effect looks like. Note that everything after the last keyframe will be at the same zoom ratio. In between the two keyframes, it is a linear progression between the two options. On Vegas 4 and 5 the window may look slightly different, but the operation of the keyframes is the same.
If you are adding an effect, it works the same way. This is useful for fading into an effect such as black and white. |
