Anybody help!

We just got ARRI Alexa, and these days try to understand how it works. For the time being, main quiestion is correct monitoring of the image. When we look at viewfinder, image is much better, than when we trough the recorded video file into computer, (format ProRes4444), .mov
Both in PC and Mac the picture has less color and looks kind of pale.
Give me please at lease direction, where to search.

thanks in advance,
Shahri

You are looking at the Alexa LogC as output on the ProRes files, a simple search for Arri LogC will bring a vast amount of info.

That flat image is designed so that when graded it offers post the most amount of info possible.

The real answer (which you've probably figured out by now) is that you're looking at the 709 conversion in the viewfinder and the Log C version from the recording. This is all under menu control by Color/Gamma.

If you record on Log C, which allows the most control in post poroduction color correction, you must "process" your dailies and apply a 709 or one light color correction to have a more proper color through the editing process.

Once your picture is locked, you can conform to the original Log C master and then color correct the finished project shot by shot using software like Resolve, Baselight, etc.
