It appears that only the BPAV folder is altered by Mountain Lion. If you drill down to the next folders you can verify the number of bytes the the clip folder (with XDCAM this is the CLPR folder) in the same way as before, by using “get info.” It’s not as elegant, but it works if you happen to miss the number before it changes.

Hmm. I haven’t tried wav files. But I haven’t seen it in any other than XDCAM files. I too drilled down and saw that the individual files were still identical sizes and that only the top, “BPAV” folder changed size. Have you seen this with other kinds of file/folders as well?

It’s especially worrisome to us because we use this same protocol when duplicating and backing up our media to drives, LTO tape, etc. It’s the only quick, bombproof way that I know to check that one folder is identical to another across a whole spectrum of situations.

[Scott Billingsley]

I agree, Louis. The added byte size is not that large (in the kilobyte range) and roughly correlates to the size of the folder.

I’ve been busy and haven’t had time to wade through the forms to make an Apple bug report yet.

QUESTION: Do you have Cinemon onboard your computer?

It does seem that only xdcam files trigger this weird, invisible response from Mountain Lion. I’m thinking that it might be a glitch where an xdcam specific program interfaces with the operating system.

This is what I am coming to conclude as well, Don.

I started the process of filling out a bug report with Apple.

[Scott Billingsley]

Thanks Don.

Do you need to make the transfer within the program in order to take advantage of CRC?

[Scott Billingsley]

Thanks for your response, Craig

I do not know what CRC is.

I have used the copy and “Get Info” verify system I described for years to transfer many terrabytes of P2, XDCAM, R3D, AVCHD and H.264 camera media. That way I am assured of saving all metadata and further, it allows us to treat our original card information exactly how we would treat an original tape. Further, should we have an issue with the camera files in the edit, we can copy the files back, remount the card and “restore” it in the camera. This has saved us in post several times. It’s simple and — until this issue came up in Mountain Lion — bombproof.

If I can’t resolve this issue however, I’m not sure what to do…

With P2 Log Pro you to just click on a P2 folder. The clips pop open in a scalable window. Nearly instantaneous.

Shane,
We just loaded the new, Xpress Pro 5.7 which massively improves the P2 support! It reads MXF files from folders on a drive (without needing virtual P2 cards). In fact, the program’s entire workflow is now MXF-based rather than OMF. If your workflow is 720P I think you’ll be fine.
