Luminance
Soliciting solutions to an ongoing problem that I have been trying to address for some time. I have spoken with several of my colleagues as they also seem to encounter the same problem as well, with no probable solution.
It would seem that everytime I create a project out of FCP, when I ultimately go to output it, whether it be run through COMPRESSOR for an ultimate burn to DVD, or run it through a standard codec ideal for internet like H.264, etc., the final output always seems to show up maybe 10% brighter on playback then what my canvas was reading. Even when I keep my display color calibration the same and playback any uploaded material to the internet, or playback a burned DVD on the same computer, it still shows up brighter.
Any probable solutions? Is it something that I may or may not be doing in the output process? Has anyone experienced this before in such a way that they have a probable solution? Right now I am merely slightly adjusting things in my canvas to compensate, BUT ULTIMATELY I WOULD LIKE THE FINAL OUTPUT TO BE THE SAME AS WHAT IS BEING READ IN MY CANVAS.

Hi David,
In QT Player Preffs, had you set “Color compatibilty with FC”?

No thats not want you want, you want the video to match your external monitor.
Look David, you are trying to match Video on a Computer screen to material that is being viewed as Video on a video monitor / TV.
It’s about working to that goal in mind and using tools that accomplish your vision.

Hi,
I think your monitor is not calibrated for H.264 codec, Sometimes we calibrate our monitor for HD or something the luminance value must change. I think you want to calibrate your monitor for H.264-dhanil

As the orginal post states, REGARDLESS, of where and what the monitor is calibrated at (whether 1.8 gamma, 2.2 gamma, native white point, etc. etc.) the final output always shows up brighter; whether it be output to a DVD, or output to Internet, the playback always has a brighter look. Something “seems” to occur in OUTPUT process.

And as the original post requested, “Do you have any solutions” in which to acoomplish that goal?

Yes

Yes, the QT prefs are set to Final Cut compatiblity. In fact I compressed a file with the H.264 codec and played it back with QT on the computer and it looks great; precisely the way I like it; compatible with what was shown in FCP as it should. However, if I burn this H.264 file to a sample DVD for playback on the computer or TV, it seems to show up slightly brighter. I do mean slightly. Be nice to find some level of relative compromise; or maybe I am being more of a perfectionist on this matter then need be.

Long story short part 1, Apple has huge problems properly and consistently handling gamma.
Long story short part 2, FCP always applies a gamma ‘correction’ in the Viewer and Canvas windows regardless of how you have your monitor calibrated. That is one of a few reasons why you never trust what you see inside FCP and have to use an external monitor.Check out this post about ways around the gamma problem (read the post as well as the comments).

Hi David,
I gave up about the Gamma long ago.
I use an external calibrated monitor that is my reference.
I’ve been having the same issue with H264 for the web, I don’t know why but they end up clearer that they should.
Now when I make the H264 in Compressor, I set the gamma to “1.02”.
Done.

Thanks Andrew!! Thus far it would appear that the “collective” answer is to refer to an “external monitor” to use as a reference point. I currently am using a G5 to edit all of my material and use one 19″ Apple Display Monitor to edit all of the material (on limited budget right now). So short of sounding like an idiot, am I to hear everyone suggest that I should set up a second calibrated “external monitor” to preview the material before output, to use as that reference point.
And thanks for link; I will check it out.
