10-bit 4:2:2 Video GREEN in DV Sequence ???
I am assembling a video from multiple sources, which will eventually be exported as a 1024×768 QT Movie.
One of my sources was digitized 720×486 Uncompressed 10-bit, and whenever I drop it into a sequence that is EITHER DV or a frame size OTHER than 720×486 (CCIR 601 NTSC 40:27), the video changes a vivid greenish hue — almost what it would look like if the Chroma was reversed on a component signal (Pb/Pr).
I thought FCP6 could work with multiple formats in a given sequence…
FYI I’m running FCP 6.0.3 on a Macbook Pro with eSATA card running to an external RAID. All footage was digitized by someone else in other locations.
Help!

First, quit FCP and trash you prefs.
If that doesn’t work. come back.

Sorry, I should have noted that I’ve used FCP Rescue and trashed, tested, restored, tested, etc.

Trash QT prefs as well?

😀 Excellent.
Have you trashed the Constant frames?
QUit FCP before trashing anything.
Also, have you tried a new project with just that movie in a dv sequence? Just trying to eliminate stuff here.

Isn’t that what FCP Rescue does? I haven’t manually trashed prefs in a long time — ever since I started using FCP Rescue. I save the prefs with it, trash them with it, re-open FCP and check the problem. Then if the problem persists, I restore the prefs with it.

What’s weird is this:
I exported one of the 10-bit clips to DVCPRO DV, re-imported it, and it worked fine in any sequence.
When I Media Managed all of the footage, re-compressing it to DVCPRO DV, all the Master clips in the resulting new Project File were green to start with.
I’ll try trashing Constant Frames.

FCP Rescue does not trash QT prefs to my knowledge.

Constant frames do not get trashed with FCP Rescue.
The constant frames are located in your FCP documents > Render Files folder or wherever your render files for your scratch disk are set up.

Okay I’ve figured it out.
For some reason, even though the preview render would play back in real-time with the green hue, when I forced a full Render ALL (with everything checked in the Render All menu), the clips play back in the correct color.
I’ve never seen that before, but it seemed to be a preview render issue.
Thanks to everyone for their help!

[Travis Marshall] “all the Master clips in the resulting new Project File were green to start with. “
Is that only in FCP, or is it in Quicktime as well?
