Use of Broadcast Colors

I need to use Broadcast Colors on many projects. Almost all projects require several smaller segments to be rendered then assembled into the final project for rendering. Is it necessary to use Broadcast Colors on all renders or just the final?

You should use this filter on only the final render.

You should probably not use it at all. It is truly a useless filter. Use the color corrector along with the vectorscope, etc. You'll get the results you are seeking.

It's actually not what I would call a useless filter.

If you open up the scopes view and set it to a histogram you can see what the different settings in Broadcast Colors do to your image range.

I think what Craftech is saying is you can accomplish the same thing using color corrector. The Broadcast Colors filter is a hold over from earlier Vegas versions and only "clamps" a narrow range. You can use Color Corrector to do the same thing and so much more.

The best way is have scopes open while adjusting using Color Corrector viewing your output on an external monitor.

Try this:

Drag and drop the Broadcast Color filter on some event. Switch on the scopes showing Vectorscope, the lumiance waveform and the luminace Histogram. Now click the filter off and on several times and see how the scopes respond to the change. Now leave the Broadcast filter off and drop on the Color Corrector. Adjust both Gamma and Gain and observe.

I would agree with that.

Mainly what I use the Broadcast Colors filter for is to catch anything I might have missed. It seems to affect only images that go over the line. So generally it doesn't hurt if it is the last in the chain.
