HDV:What You NEED to Know
Vegas Movie Studio (VMS) might be an inexpensive video editing tool, but
don't let that fool you. This is a powerhouse application. In this
tutorial, we're going to look at masks, and how you can use them in VMS
to create very professional-style effects and looks. Compositing tools
are generally found only in higher-cost, or more professional
applications, but you'll find several compositing tools inside Sony
Vegas Movie Studio.
To complete this tutorial, you'll need to download the MaskPak from the VASST website. (if you have the professional version of Vegas, you don't need these masks, you can create them with Bezier masking tools very easily. These masks were made inside Sony Vegas+DVD, and exported as .png files for use in VMS)
Open a new project, and put video on the lowest track. (track three by default)
You'll want to click/drag the right
edge of the mask to drag it out to the length of your video clip (known
as "events" in Sony Vegas Movie Studio).
This will make the top track be the
Parent, and the next track down the child track. Notice that the top
track has its "arm" around the child, signifying that the top track is
This will cause the white section of
your video preview to disappear. That's OK, it's what we want to have
Your Preview window should look like the one below.
The area that was white now displays the Black and White filtered media. We could stop here, but the contrast between the greyscaled media and the colored media isn't intense enough to suit the eye in this image.
Drag the Color Curves filter from the Video FX tab to the lower image. Make your curve so it looks like this:
This should intensify the chroma/colors in the lower track areas seen outside the mask, or greyscaled area. You may need to adjust the curves to suit your specific image, but the curve seen above is usually a very good starting point.
The resulting image is seen above. Again, we could stop here, but in this particular instance, I don't like how harsh the line is between the two resulting images, so we're going to drop a Gaussian Blur from the Video FX tab, onto the Mask found on Track one. Use the Extreme Blur preset to achieve a blend like the one seen in the image below.
Since the blur is applied only to the mask, it blends the two images together without affecting the sharpness of the images themselves. Remember that blurring the mask will soften the area that divides the images. Another tip is to lower the opacity of the black/white image, blending with the lower image so that hints of color show through.
Vegas Movie Studio has a lot of little secrets under the hood; this brief tutorial should help you discover some of them. Learning to use masks is a basic starting point for learning the tricks of compositing. Once you get comfortable with compositing, you might find it worth your while to step up to the more powerful professional version of Vegas. Vegas Movie Studio offers one blending option, while the professional version of Vegas offers 11 blending modes.
