Checking an entire movie for excess Luma and Chroma Quickly
I am mastering a 50 minute animated project for my company to digital beta. I have found from spot checking that there are clips that exceed the legal limit for luma and chroma. Unfortunately. it takes forever to go through frame by frame or playing the film using the “Option+P” option to find each frame. I was wondering if there is a fast way to mark those excesses on the timeline similar to the way audio peaks can be marked so I can quickly go in and fix those clips. Anyone know a way to go about doing that?

You can just apply the Broadcast Safe filter and knock everything down to legal.
I generally spend about 5 hours on each 22 minute show here going clip by clip setting the 3 Way CC, Levels and Broadcast safe filter on each clip. The only way to do it right is to go clip by clip and check all the shots and CC accordingly.

Walter – if you’re doing 3-way CC, is applying the Broadcast Safe filter really necessary? Or is it just to insure you didn’t miss something?

Broacast Safe is the cheap, fast way out. It knocks everything down and unless you don’t have the patience
you should go clip by clip.

I follow this method as well, and though it is time consuming, it’s the safest way to make sure you’re “legal.” I rarely ever use just the broadcast safe filter, though I have from time to time, i have used just the 3wayCC filter. I think, if you just drop the broadcast safe filter on it, your image can get a little “flat.” Maybe I’m wrong……

absolutely and depending on how out of legal you are, you can get some serious clipping where whites and reds can drop in shades to grey and very dark red.
Best to use the 3 Way CC and Levels filters for most everything.

[walter biscardi] “I generally spend about 5 hours on each 22 minute show here going clip by clip setting the 3 Way CC, Levels and Broadcast safe “
more than a half year ago I sent you my 1z1_mastering plugin for testing.
it seems that it could save you hours if you would use it.
or did’nt it meet your expectations?kurt

Well, it knocks everything down above a certain point, on a curve. For example 110 might be brought down to 100, but 98 might only go to 95 and 95 might go to 94 and so on whereas nothing above say 93 would be affected at all. Which is alot better than just adding a proc amp type adjustment where everything goes down in much more of a linear fashion.

You are a lucky man Walter…I often have to squabble to get at least one hour to color correct a 1 hour show for network broadcast. No joke.
