GH2/FCP not playing nicely
on Apr 5, 2011 at 11:22:23 pm

Something silly is happening when I dump data to a disk.

Using MBP Unibody 17", FCP 7.0.3, and a 6TB eSATA RAID for scratch n capture.

I can Log n Transfer without issues directly from the GH2's card via a cheapo card reader.
I back the footage up by copying the entire "PRIVATE" directory into a named dated folder. L&T will mount this directory, even let me preview all the footage, and will correctly transcode ~2/3rds of the clips.

The remainder of the clips stop transcoding with an exclamatory stop sign, complaining "error: no data." Clearly, this is not the case. I can play the clips through in VLC with no glitches.

A client has also stated they're having this same problem with GH2 data I sent on via data DVD. I don't know their setup.

In each case, the data structure 'seems' intact once copied, at least as per size, number, names, and locations of files.

Where's the stupidity cropping up?

I don't have ClipWrap to use as a workaround, and want to figure out where the trouble is so I can relay a fix to my client, as well.

So you can L&T fine directly from the card but not from a hard drive copy? I haven't had any trouble with L&T from a hard drive copy, but I have always just grabbed the AVCHD folder and copied that. Maybe try that...

Exactly.

This is essentially how I've worked with P2 for years now. Have worked with clients' HMC150 footage without problems on this setup as well.

Apple's site had this suggestion:

It's FCE, but thought there might be some carry-over... suggesting to transcode to AIC/Plain Stereo. That failed exactly the same way.

Have you tried trashing preferences, fixing permissions, and running Disk Warrior on all your drives. These are the standard maintenance procedures to try when FCP begins to act as though it's possessed and before throwing your hands up in desperation.

BTW, forget about AIC for the rest of your time on this planet. It's old news, it's an inferior codec, and it's essentially a completely dead format except for FCE, because Apple didn't want to put ProRes encoding in their cheap editing app so they could encourage more sales of FCP.

I didn't have illusions of reverting to AIC in daily workflow, but figured, "hey, if it'll let my client access the footage..." No go anyway, so it remains dead to me.

Also no go on the disk repairs/permissions/pref trash. The issue appears on the same files, as though the files are being corrupted somewhere in the transfer, but where? Flaky card reader? If so, why can I preview files faultlessly with everything BUT FCP (or MPEG streamclip, or Cinema Tools, or anything I have that could rewrite a file if only it could read AVCHD in the first place)?

Any other ideas for workarounds until I iron out the root cause?

After exhaustive testing, the problem is with my RAID, not FCP or the GH2 footage. When I copy the PRIVATE directory to the laptop hard drive, it L&T's without issue. When copied to the RAID, files sometimes become corrupt and won't L&T properly.

Serious problem, but little to do with the camera or the software.
