I recently shot some footage onto Class 6 Transcend 16GB SDHC cards through a Kensington adapter on my EX3 at an academic seminar. During the shoot, when the cards were full, I would eject them from the camera and transfer them to a Macbook through Sony's Clip Browser software (CRC was on). At the time, all the clips appeared to transfer correctly and the clips showed up and played back in Clip Browser.
I believe one of the cards I used is faulty or has bad sectors on it. Footage from a couple of sessions I shot will not import into Quicktime format. Footage shot on different cards worked perfectly. When I try to convert these raw files from the bad card into editable Quicktime movies I have gotten a number of errors which prevent me from using the footage (this happens when accessing the SDHC card itself and from the backup BPAV folders transferred to hard drive immediately after capture).
Accessing the SDHC card in XDCAM Transfer 2.11, the clip fails to build a preview image and I get the following error message: Failed to import movie from file at Volumes/SDHC CARD 5/BPAV/CLPR 672_1417_02/672_1417_02.MP4(-50)
Upon trying to import the clip using XDCAM Transfer 2.11 I get the following error message: Exception opening XDCAM EX file (Condition Failure - moov existence).
This happened at least two times during the shoot. Once when I transferred and then erased the card after backup (before having any suspicion of the bad card), and then later, where the original footage is still on the card. In both cases, the clips consist of long continuous takes where the camera shifted to the second card slot when the first was full. Footage shot on the continuation cards after the transfer is fine if played independently, though no segment of the entire clip with convert through XCCAM Transfer if Clip Browser has stitched it together including the corrupted sections.
I have attempted to copy the troubled clips in the camera to a blank SDHC card and then import the copied footage and get the same errors. I have also failed to import the same clips through the Log and Transfer plugin in Final Cut Pro 7. Clip Browser also will not convert any of these files to MXF or any other format.
Is there any way to recover the problem clips.
Have you tried using XDCAM Transfer to recombine the problem clips instead of Clip Browser? Have you tried selecting in and out points of your problem clip sections within XDCAM Transfer and import most of the clip?
Clip Browser sees all the files and plays the uncorrupted portions of them, as well as combining all segments together, but obviously will not convert to any Quicktime friendly format, nor will it convert to MXF or DV through the export command.
XDCAM transfer will not allow me to select and import any section of the problem clips, even if most of the video in them is fine. Constant preview errors and a constantly greyed out import button.
