View Full Version : P2 Footage Corrupt - need some help

I have been using the workflow suggested here.

Shoot on location, place P2 Card in Mac Laptop, use disk utility to make a disk image (read only, no compression). Back-up DMG file to external hard drive.

After two days of shooting and 7 P2 transfers one reel will not import into FCP.

This is the first time this has happened and I am going crazy. I have tried everything.

I have tried to import direct (first clip is fine then get nothing but static in the preview window and the rest of the files will not import)

Tried moving the files back to the P2 card and using the Camera function "fix clip" but it is "unable to fix clip".

Ran disk utility on the disk image - found several errors. Converted the DMG file to read/write and ran disk utility (after fixing the errors, was still not able to bring in footage).

Can pull some of the MFX files off of the Disk image. Is there a way to convert the MFX to Quicktime?

I don't know what to do as I need this footage (will be almost impossible to recreate).

Also, makes me very nervous going forward. What caused this and how do I avoid this in the future?

I have two laptops - a new macbook pro (last model before intel switch) and an older powerbook (550 mhz) with a brand new fast (7200 RPM) HD. The corrupt disk image is from the older powerbook...could this be an issue? I saved the disk image to the internal HD before backing up to external HD. Also, is there an issue with the PCIMCA slot?

Just trying to figure it all out.

There was another post somewhere with a similar issue and if I remember correctly the person found out his laptop hard drive was bad even though it seemed to working fine. i also have a macbook pro. Never had this issue. I never go to my internal to save the dmg's, I go to a 2 bay firewire 800 drive enclosure for media dumping, so I have 2 drives with the same material. They are formated as mac os extended not journaled. Nothing else is on these drives but media. Maybe when we hear from others we can pinpoint it because now it seems as if the dmg method isn't foolproof. Maybe it will come down to not using the internal laptop drive where bad sectors, fragmentation , or the drive just going bad may corrupt the files. Another method to pinpoint the issue maybe to put the corrupted files on a pc and see if can be opened on that with the p2 viewer.

One thing that is very wierd is that there seems to be some cross contamination. By that I mean the first clip on the card is viewable, but the last frame of the first clip is from footage we shot eairler in the day. In other words, the first clip is new footage, but the last frame of the new clip is an old clip we shot. Then, every clip from that point on is nothing but static.

What is the error message you receive? Because i dealt with some issues this week as well. My laptop was totally screwy, its in the shop now getting a new hardrive. One file of P2 footage was corrupt. I couldnt copy or transfer it anywhere. What i was able to do was open it with final cut pro. I discovered it was just one clip that was corrupt. After trashing that file everything turned out fine.
