I've said in an earlier post that I rarely use black video, but rather leave a gap in the timeline to achieve this.

I'm now wondering if there is any difference between black video, the black rendered by premier in any gap in the timeline, or a black colour matte (NEW/colour matte, select black from the pallette).

I know that black video has certain properties (I think something to do with IRE values) and that there is even hardware (black burst generators) which do nothing but output black video.

I'm off to do some research.

In the meantime does anyone know anything about the mysteries of which I speak?
