whites shift when rendering with broadcast safe filter
Hi there,
I haven’t encountered this problem before. I’ve applied the broadcast safe filter to every clip in a wedding video shot on DV with a superwhite Canon GL2. Most set to ‘normal’, some ‘conservative’, etc. Everything looks good in the scopes and with the range check on. Then when I render — set to 8 bit YUV rendering, white, best — the whites shift and I am back with the same problem. If I open the clip and deselect the filter, then select it once again, the now unrendered footage again appears perfect. When I re-render, it throws the whites past 100. What’s going on?

In your sequence settings, do you have filters unchecked in the render control tab? That would sure be the problem.

Nope. It’s checked and files are indeed being rendered.

Is video processing for the sequence set to super white?
All the best,
Tom

That would have no effect. Super-White only controls what is CREATED in FCP. If you have the broadcast safe filter applied, then it should still do it’s job.
I still think it could be sequence settings. Did you check the sequence settings for your current sequence, or did you check the overall sequence settings. It could have been turned off for this particular sequence.
Does it render any OTHER filters?

u mm, if your whites are too hot, won’t broadcast safe bring them down to a “safe” level, thus introducing some grey??

Thanks for all your efforts, I really need to solve this mystery – and fast! I normally use the 3 way corrector and bring down the highlights, adjusting each clip individually. I was trying to save time on this project. So much for that.
To answer your questions, Bret, the filter checkbox IS selected in the current sequence, not just overall. And other filters, such as sepia, are rendering fine. Additionally, I’m processing whites as whites.
To reiterate the problem, the raw footage registers whites to the max, 107 on the histogram. When I bring this down with either the broadcast safe filter, or the color corrector 3 way – or using both together – such that the histogram and other scope readings read under 100 and the range check gives me a green checkmark, THEN RENDER, my whites shift back into the hot zone, now peaking at about 103-105.
I’ve trashed the prefs to no avail. I wish I could attach screenshots but seems the cow won’t allow that. PLEASE HELP, SOMEONE!
Thanks, SC
