Media Generators

I am looking at the documentation for Vegas and came across media generators. It says that media generators are a special type of plug in that creates virtual media files. You can add text, backgrounds, etc....

Can someone explain in English why you would use this and what a background would do? I am looking at the backgrounds, and they have fences, ridges, etc....

HELP!

Say you need solid black, the media generator will do this for you
Why would you need solid black?
Pretty common to use this at the start of a tape before the progam starts.
Color bars are another gnerated media, again, pretty common to have them at the start of a tape.
Static text is another generated media.
Now say you want your text over a graduated fill, well the media generator will also do that as well. Just have the text with a transparent background on one track and the generated grad fill on a lower. Or use text to cutout the grad fill and you have text with a grad fill.

But there's more to this. Compositing a B&W grad fill with the right compositing mode can be used to make selective exposure adjustments or even color adjustments. In some cases adding a color works better than using the traditional CC tools as it doesn't increase noise.

There's a list way too long to list of uses for generated media and that's without even getting into the ones that use fractals.

Think about it in this way:

- FX - takes an input frame, modify it, and output a frame
- Transition - takes 2 input frames, modify/combine, output a single frame
- Media Gen - Takes NO input frame, create a single output frame

It is used to create an image from the information you provide without any base image - like text, gradient, solid color or random pattern generator.
The image it creeates is placed before your image (e.g. text) or behind the image (solid colors, clouds etc.)
