  Premiere Pro CS5 – Color of Exported Clip changes when exported on another computer…

  Posted by Alex Reyes on March 15, 2011 at 9:24 pm

  Hi,

  I have a bizarre issue that I’m experiencing —

  I have a windows7 laptop with Premiere Pro CS5, using Color Finesse.

  – I color corrected a clip on one laptop and then exported it, with good results on my reference monitor. So I wanted to use another computer to continue exporting this clip, so I can use my reference monitor for other work.

  – I moved the external hard drive with the data to another laptop and exported the same clip with the same color correction settings, but I got a clip which has completely different color than the first one when looking at it on my reference monitor!

  – I tried moving this same hard drive to another computer, exporting the clip, and the color correction results were good — identical to the first clip when looking at them on my reference monitor.

  So my question is, what can possibly be happening on the laptop computer where the color is coming out differently? I do notice on that LCD, that the clips do look completely different in premiere pro, even without color correction, but I thought it could just be the LCD screen of that laptop — but the actual clips come out with different color when viewing them back on the reference monitor.

  Is there something I’m not aware of?

  Any help is greatly appreciated,
  Thanks.

  Too much ambiguity in your color management.

  1. What is your color reference monitor?
  -How is it connected to your desktop?
  -How is it connected to your laptop?
  -Are you calibrating with color bars or something like a Spyder 2 (if it’s an additional computer monitor) on both the laptop and desktop?

  Depending on how it’s connected, it sounds like the graphics system on the “messed up” laptop is probably pumping it through a different LUT… could be a few things going on.

  Thanks so much for your response Angelo, to answer your questions:

  1. Panasonic G25 plasma in THX mode (adheres somewhat closely to REC709)
  2. laptop connects to it with Matrox MXO2 thru hdmi
  3. a desktop connects to it via Aja Xena card (now known as Kona)

  The “messed up” laptop is not connected to the reference monitor at all, it’s just being used to render a sequence with the color profile that was created.

  The other desktop computer is also not connected to the reference monitor, it was just used to render the clip as well — and the color came out properly!

  From what I understand, Adobe Premiere Pro doesn’t work with LUTS, why would this laptop be pumping out a different color given the same clip, color profile and program? I tried a fresh install on this laptop, same results…

  Any ideas would be greatly appreciated,
  Thanks

  Premiere Pro itself doesn’t use LUTs in-system but is also doesn’t render through the videocard’s LUT. Lets say if you have a calibrated monitor and an uncalibrated one on the same system, the preview window would look different on each.

  ‘The “messed up” laptop is not connected to the reference monitor at all, it’s just being used to render a sequence with the color profile that was created. ‘

  I Think I may misunderstand the issue, so let me rephrase it: You color corrected a clip looks amazing, brought it on your laptop to render, brought it back to your color monitoring environment and it looked weird?

  Yes, that’s the issue – I created a “color profile” on the reference monitor, when I exported and created an mpeg-2 dvd clip using the computer – it looked fine. I also created a test dvd disc, it looked fine.

  I took this exact sequence with this color profile, and I brought it to another laptop, to finish rendering the whole clip to mpeg-2. I rendered the mpeg-2 clip and created a dvd disc, and noticed that the color is not good!

  So I took this exact sequence with this color profile to another computer – rendered the whole clip to mpeg-2, the color was fine..

  Any thoughts? It’s so strange…
