Color / luminance correct set up?

[Jim Wiseman]

If it is for broadcast, you will definitely want to keep it in SMPTE specs. 16-235 YUV. 0-255 is an RGB computer space. You can work in it, but it must be tweaked for broadcast. Trust the YC scope if you do not have good monitoring. Don’t let any of the whites go above 100 IRE units, or any of the blacks go below zero. I would keep the blacks just above that. Then you should be alright. You can use Curves or Proc Amp or several other effects in Premiere to control luminance. Fast Color Corrector is a good effect to control saturation and quick color balance problems. There are several good color correction tutorials on this forum and adobe.com

As far as what you are bringing in from Vegas, I don’t know that program. In fact, I am just beginning on Premiere Pro from Final Cut/Media 100 Suite/Avid. I’ve been doing color correction every day on Premiere Pro 5.5.2, and exporting ProResHQ clips. But color space and luminance issues remain the same on output.

It still sounds as if you are having a conversion problem between these programs/codecs spaces. Someone here or on the Vegas Forum may be able to help you further. Good luck.

You need to check with the quality control engineers of your distributor. You can use Curves or Proc Amp or several other effects in Premiere to control luminance.

Sorry for the double post, thought I was editing. The bottom post has additional information.

Thank you very much Jim.
By the way, I couldn`t find PRORES as an export option in quicktime inside Premiere Pro 5.5

–if you are on Windows, you cannot export to ProRes. Only import. (thanks a lot, Apple)

Thank you Jeff. Yes, I`m on Windows.

I am editing footage from Sony EX1 cameras in Premiere Pro CS5, and using the YC Waveform scope. The levels look broadcast safe while previewing, but when I render the work area, they exceed past 100 and below 0.

Any idea why?

I also posted on the Adobe forums with more information.
