Gamma problem – ProRes 422 vs. LT / Proxy / JPEG
Can anyone else confirm this?
In this example, ProRes 422 HQ and non-HQ have darker gamma. ProRes 422 LT, Proxy, Animation and PhotoJPEG all have the same gamma. (I didn’t compare ProRes 4444)
Here’s a screen shot.

There is no way you can properly judge gamma by that picture, and definitely not through Quicktime on your computer monitor.

I agree JG.
Navarro note that you will need to also trash your QT prefs after installing FCS3 to access the new gamma rendering intent feature for the previous versions, The original ProRes versions will retain the previous gamma settings until the prefs are purged.
See the new PR versions have the gamma settings correct on install, the existing PR versions will need to have the prefs re-set to allow the new gamma settings to stick.

Thanks for the heads up. I’m assuming the file is user/library/preferences/Quicktime Preferences?
I rendered all those with ProRes’s auto gamma on.
