Sony Vegas Broadcast Colors
Hello, I am playing around with demo versions of Sony Vegas Pro and also Edius to get a feel for them. I really like Vegas Pro, but the Broadcast Colors filter when ticked to 16-235 does not seem to be quite accurate.
When I put the same footage into Edius (which is supposed to be a broadcasters favourite), it shows blinking error dots that a few pixel portions of the color black are 15 instead of 16. Can anyone comment ? Many thanks.

When you say “the same footage”, do you mean that the same source file is going into both Vegas and another piece of software? If so, the result you are seeing is expected. Vegas would apply the broadcast filter only during preview or when rendering an output file. It does not apply a filter to the source file because it is not a destructive editor. It does NOT change the source file.

The Broadcast Color’s filter has several presets: Regular, Lenient, and Conservative. Which did you use? Each one will allow different levels. If you used the Conservative setting, there shouldn’t be anything illegal getting through.

Thanks for your response John (and Bob). I used screen capture software called Camtasia which captured 1280×1024 at 30p. The active video was 1280×720 so there are black bars on the top and bottom. In Vegas I rendered a small chunk to a 1280×720 without cropping (now additionally giving black bars on the sides).
I opened the result in Edius with zebras enabled. Some pixels in the image and top/bottom black bars came up out of range and the black bars on the sides were completely stripy.
Now using the Conservative setting as you suggested has cleaned up all of the active video image, but parts of the black bars are still showing out of range. I can solve this by processing just the image to 720p, but I found it an odd result (in case of broadcast work in the future), which made me wonder.
Vegas strikes me as a great editor that could deal with a feature film by just one guy. I admit I need to delve further, but I was interested if anyone had any further views.

Sounds like you need a black solid color media on a track under your video.
In Vegas, “nothing”, is always 0, as far as I know. When you have an aspect difference and therefore have black bars, then those bars are “nothing”. Nothing meaning that no video exists in that location. The effect filters like Broadcast color only work in actual video pixels from your source or generated media.
This can be solved by putting a solid media generator event on a track under all other video tracks. This event being the full length of the video. Use a legal black for the solid media color.

That makes perfect sense to me, and I hadn’t thought of that. Thanks.
