FCP QT Still export — what’s the color profile?
Hiya
I’m doing some detailed image correction for a broadcast show — we have dropout on the original material, so I’m trying to export stills to repair the image in photoshop.
I have done repairs in FCP when damage is to background, static objects, but have to export to a photo program to repair foreground moving objects like faces.
Unfortunately, the Quicktime Still Image export does not have any option to include/disclose the color profile information that Photoshop wants. By the time I’ve made my round trip, the stills have a different gamma/luma situation than the surrounding footage.
I’ve tried imposing an NTSC color profile, RGB profiles, etc, in Photoshop, as well as applying the broadcast filter or constraining the colorspace to 16-235, and I can’t get the exact match I’m after in FCP.
Anybody have any ideas? Maybe it’s just easier to pull the whole clip into After Effects and make my adjustments that way?
thanks

Photoshop recognizes many color spaces, alas, YUV is not among them. The gama shift you’re seeing is the change from YUV in FCP to RGB in Photoshop, & back to YUV in FCP. If you can’t match it with the CC tools in FCP, then you might be better of working in an RGB app like After Effects.

I believe this has more to do with the formats you are using to round trip the images, rather than color profile settings. What are your settings?
Someone correct me if I’m wrong, but I believe the best practice is to turn off color management in photoshop while you are working with images intended for video output. As Arnie says, YUV to RGB to YUV translation is never transparent. You may want to try the “bitjazz” codecs, (www.bitjazz.com) they seem to promise very accurate YUV to RGB translation. I haven’t tried these myself, but would be inerested to hear what your experience is, if you go this route.
