即使QT7本身,也是个烂摊子,苹果在color shift和gamma shift方面的屁股从来都没擦干净过。

以上链接是一篇关于QT色偏的讨论
It's really chapping my ass.
Update: Thanks for the responses everyone. Here are a few updates. Keep in mind, I am on a mac, cut proxies in premiere, online in resolve, grade, output prores, back to premiere, output h.264 for youtube/vimeo. I noticed the gamma shift when viewing the h.264 output in quicktime and on youtube in safari.
Today I took a look at the h.264 in VLC and in Quicktime. In VLC, the gamma matches what I see in premiere. I also took a look at the prores masters that came from resolve. The prores masters compared with the h.264 (in quicktime) match eachother. So, since i was never viewing the prores in quicktime, just bringing it straight to premiere, I thought premiere/media encoder were shifting the gamma, when in reality I think that premiere shows the footage differently than quicktime. the prores and h.264 final match each other when they are both in VLC as well. Does this make sense? If not I will clarify.
What I am assuming now is just what I have always known... different methods of playback show video in different ways. I was frustrated that after grading exactly to how I wanted it, that the final product looked different. This is something that has bothered me for years.
还有苹果自己的官方论坛上一篇无人响应的求助
