      Hi

       

      I saw a tutorial where the guy talking about color correction said that the luma value should never go over 100 (he used the Waveform monitor in FCP X)

       

      I shot this video and applied some color correction. After this process, the luma value is way over 100%. I think it still looks ok, what do you think?

      I also applied the broadcast safe plugin but it didn't do much at all..

       

      Thanks

      Basically the only time you truly have to worry about luma / IRA values over 100% is for broadcast television. I know you have seen infinate white backgrounds and I am sure they most are over 100%. Plus, if you think about it the white background on VM is probably over 100%.

       

      Hope that helps,

      Staying at 100% or lower is good practice and will insure that your signal looks consistant across all platforms.  Go over 100% luma and 75% chroma and TV station proc amps will force your signal into legal color space.
