Over exposure indicator

Hey guys,

I'm migrating a final cut pro user to AVID and they asked me an interesting question about checking for over exposure.

I know that when we color correct, we can use waveforms to check for over/under exposure.. but is there a "Zebra" mode like final cut, that shows lines over the over exposed video instead of having to use waveforms??

Thanks!

Nope. Teach them waveforms. More universal anyway.

If they are AMA linking source media (and that's the best way rather than using import) then the set source settings on each clip will show a histogram of the values. You can shuttle the source clip with the slider above the histogram to check specific sections of content.
This also ensures they have the correct level mapping selected and they can change it if need be.
However make sure they don't change the mapping to bring down peak whites if the blacks aren't sub black.
We see more errors with incorrect level mappings than anything else.
