    I got a short animation from the “graphics guys” today that had some very saturated colors in it. My reds were actually off the scope in my room. I think they were actually bleeding over to the scope in the adjacent suite. They were that hot. Anyway, after reading the posts below regarding the broadcast safe filter, and not having the time to have the graphic rerendered, I decided to try the filter and see if it would work in this case. The luma levels on my graphic were within specs only the chroma was hot. After applying the filter and fiddling with the settings, it seemed to have little effect (if any) on the saturation of the clip. It was still off the scope chroma-wise. Does this filter address the chromanance values of a clip or just the overall white/black levels? Since time was of the essence, I just corrected the clip using the 3-way color corrector. It worked OK for the moment. I asked that the graphic be rerendered for future use.
    So…
    How can Apple allow their “Broadcast Safe” filter to pass such excessive chroma levels? Or am I just missing something important in the filter settings. And…after applying the filter, I was required to render the clip even though the Broadcast Filter is in BOLD in the filter window which I always thought ment no rendering required.
    Just a little confused this morning. Must have more coffee…

    I find that the Broadcast Safe filter applies really to the Luma, not the Chroma of a clip. Chroma is best corrected via the 3-Way as you used.

    As for the RT, that’s a dynamic RT effect on many machines and must be rendered for final output. It displays just fine in realtime on my machine, but I render all CC before mastering.
