Video in iMovie is too dark. Movie's produced from iMovie have correct brightness.
I'm having a problem where movies in iMovie theater (and iMovie projects) are being displayed much too dark. If I watch the same video in the Quicktime player application the brightness is correct. If I produce a movie from iMovie the brightness of the output movie is correct.
I must have a bad 'setting' somewhere. Any ideas how to fix this?
I included a good screenshot below. It shows the exact same content in both iMovie and Quicktime player.
Computer: 27" iMac (2012), 16GB RAM, 8TB external hard drive
Mac OS: v10.13.2 (high Sierra)
iMovie: v10.13.2
Color Profile on iMac: System Preferences->Displays->Color->Display Profile->iMac.
iMac Display Brightness is set to 'the brightest' setting possible.
I created a new 'calibrated' color profile and got the same results. I've switched back to the iMac color profile.
I have closed and opened iMovie a bunch of times.
I have restarted the Mac twice.
This problem occurred when I switched between Macs. My iMac went into Apple for service, I temporary used a Mac Mini, when the iMac came back from service this is when the "dark iMovie" behavior began. (in all cases I have been booting off the external 8TB hard drive.)
Note: I've been a Mac user for about 10 years.
Thanks in advance for any help anyone can offer.
