I am running into an issue when coverting files and making them match color and contrast-wise from Quicktime .mov files to Windows Media Player .wmv files.
I am currently using Autodesk Cleaner XL to convert the files on OSX. I know their is roughly a difference in gamma of 30% between Windows and OSX, so I adjust accordingly. I was curious if anyone has had any breakthrough methods or settings in making the closest match so the files look native on both platforms.
Another thing a lot of people do is shoot for a gamma value that's in between the older Mac default and the Windows default. I believe Macs (prior to OS X 10.6 Snow Leopard) were 1.8 and Windows PCs are 2.2.
So changing the gamma to 2.0 is a good compromise...or if your encoding app doesn't use those values, adjust the video and black levels of your project about 10-12%.
I believe there is also a difference in how older CRT monitors display gamma (the number 2.5 sticks out in my mind)...but the majority of people today will have LCD...and 2.2 is still a good compromise.
