Hi Jim, thanks for bringing attention to this. I have plenty of memories of exporting h264 quicktime files out to the network for rough cut approval, only to have them blast the “dull colors” (we were working in animation, so color shifts were 100x more noticeable than on live action).
If I might ask a further question: If a computer without FCPX watches your h264 outputs, is the color still properly calibrated for them? I ask this because I found that many quicktime movies actually did contain the proper color information — it was quicktime that seemingly didn’t interpret it properly.
For example, we could watch a 1080p quicktime movie in VLC player and get a more accurate view than if we viewed it in Quicktime 7. This indicated to me that the problem wasn’t necessary the exported file, but the “player.”
My question is ‘how did they fix it’ I suppose: since it seems like the weak link is equally the quicktime playback engine… which would still inherit these issues on the client machine? Hopefully I’m asking this clearly enough…
