After posting videos to Youtube I find that viewing them in different browsers yeilds vastly different color saturation and color cast. Is there some secret to getting more consistent color from browser to browser? I am already using the recommended compression settings (as close as I can get in FCPX). Any help appreciated.
Any discrepancies will be due to the color management of the individual browser or lack thereof. It's not FCP's fault. My guess would be that you e.g. see no difference in Safari compared to FCP X. That's what you'll want to go by. There is no "consistent colors for non-existent color management" setting.
