    Premiere Pro CS6 and Media Encoder CS6 Color shift on export

    Benjamin Peterson Level 1

      Hello,

       

      I am working on an early 2008 Mac Pro with 2 X 3.2 GHz Quad Core Intel Xeon Processors 32 GB of RAM a NVIDIA GeForce 8800 GT 512 MB Graphics Card and I am running OS X 10.8.2.

       

      I have the updated Version of Adobe Premiere Pro CS6 and Media Encoder CS6 through the awesome Subscription program that Adobe has started.

       

      My footage is shot with the Canon 1D Mark IV shot 1920X1080 at 24 FPS

       

      I am importing the camera files and then exporting them after I cut them up in to Quicktime Pro Res 422 HQ files

       

      With the technical explination out of the way here is my problem. I have color right from the camera files that I like. and with out doing any thing to change the color I export the footage and get a dramatic color shift. The exported file looks desaturated and slightly green.

       

      I have tried using Media Encoder CS6 to export my footage and that has the same result.

       

      I started my career as a photographic retoucher and use photoshop and light room constantly so I am pretty confident that i know color. I also calibrate my Lacie 526 and Lacie 324i montiors monthly as well as have a sensor that will slightly shift the profile depending on the time of day.

       

      I have attached three screen shots that show the color shift exactly. Now what I need is a solution. What I am not seeing is color settings for Premiere. I am totally open to any suggestions on what I might be doing incorrectly.

          Looks like the famous Quicktime Gamma Shift Issue

           

           

          Google it for info.

            I looked that up and it did look like the problem a little but all the articles were about an H264 Codec and when I tried the fixes they did not work on my files. Do you have a solution?

             

            Best

              Calibrating your computer monitors might not be enough.  The OS, display driver and even playback software can and do alter the signal.  You need to get the signal off the computer and full screen (no GUI, no desltop) onto a calibrated display.

               

              So...how are yours hooked up?

                I've been doing this for a few years now, and have come to some conclusions. Basically, the difference between still photography and video is like the difference between playing the trumpet and the sax. What you bring to the sax from playing trumpet is your ability to read music, what you know about composition, blending while playint with others, ect. But playing trumpet tells you nothing about how to physically play a sax. So it is with still photography and video.

                 

                For starters, your carefully calibrated computer monitor is just that, a computer monitor. It doesn't display the correct working space for video. What you need for WYSIWYG in video is a monitor that can show you the Rec.709 working space. Rec.709 has a different gamut, a different gamma, probably a different white point (D65), different phosphor colors, etc., etc., etc. Enought differences that it's difficult to make a computer monitor that can successfully display Rec.709. Yet there are a couple of computer monitors that can do this (a few Eizos, one HP). The vast majority of people doing serious color correction work in video use a production monitor for just this reason.

                 

                But a production monitor isn't enough. You also have to make sure that the signals you're sending the production monitor are correct. There's a sub-industry making signal converters for signals from NLE video cards (usually RGB based) -> signals for production monitors (usually YUV based).

                 

                That said, it is certainly possible to get a very good match between your NLE suite and a DVD / BD as displayed on an HDTV. But it's not as simple or easy as a calibrtated computer monitor for still photography use.

                 

                This is probably part of your problem. But Quicktime is probably the root of it. Quicktime is, well, I guess the polite way of saying it is that Quicktime is problematic. It gives all kinds of problems. Most people have abandoned it. You should too.

                  Thank you for that great info on monitors and color. I totally understand what your saying. However if I am looking at something on the same monitor and seeing a color shift its not the monitor.

                   

                  If quicktime Pro Res 422 is not a good Codec and give so many issues then what do you suggest I export out into that will not give issues?

                   

                  Finally I will say that I have been looking at the export preview and then the source window and seeing that the color shift is there in both of them. This tells me that my Program monitor with in Adobe Premiere must be some how off. Any Ideas about that?

                    I am following you. I am hooked up through a DVI port directly to my computer. Here is my thought though. If I am looking at the Program monitor in Premiere and seeing one color then I click export and both the source tab and the output tab shows me the same altered color. This is all on the same monitor. Would you say that the file is some how being processed through my graphics card when i hit export and has it's color altered before I even render it out.

                     

                    The other wierd thing was last night since everyone seems to think this is a Quicktime issue I tried every other export codec with in the menue and did not get any change in the look of either the source or the output. This is leading me to belive that I mist have a setting wrong with in the program window in Premiere and that it is not showing me the correct color output. What are your thoughts on this?
