Corrupt P2 files

Sorry to be long winded, but I thought it would be best to just explain the problem i am having in detail.

We shot with the Panasonic HVX cameras on P2 cards. When we were downloading the cards one time there was a power interruption during the download. We did not realize it at the time, but the footage files got corrupted. We tried to open the files thru Final Cut, but were unable to.

Using Vegas Video we were able to salvage the picture/video footage, but not the audio. No worries about the audio though. We can watch the footage using Vegas Video.

Now that we have the footage, we have been unable to get it into a format that Final Cut will recognize to use it and edit it. We tried making avi and quicktime files, but when trying to import into Final Cut nothing happens.

Here are questions that I have been asked before and my responses.


1. Do you still have the original P2 cards with the footage? If you copied them to a hard drive, did you copy the full card structure including the contents file?

We do not have the original P2 cards with the footage on them. All the footage was downloaded onto hard drives and the P2 cards were reformatted. The full card structure was copied with all the contents. However, at least with us trying to repair the files, it appears that the sound files were damaged.

2. When you were "downloading" the cards, where were you "downloading" them to? Straight into FCP from the cards or from the cards to a hard drive? Or from a hard drive into FCP?

All the footage was downloaded onto hard drives. The cards were inserted into a dedicated lap top just for downloading and the files were downloaded onto a hard drive (thru the lap top).

3. There is a program called Raylight that I heard can be very useful for problems with P2/mxf media.

We tried using Raylight and so far have not had any luck with it. It could be that we are just not experienced enough in using it.

4. Did you try starting a new project and reimporting all the clips?

I did not try starting a new file and reimporting all the new clips. I didn't want to go thru that effort at this moment. As of right now, we have found that Vegas Video is the only program that was able to salvage the clips. When we tried to get them using Final Cut Pro, it would not work. I have the hard drives with all the footage on them, as well as the files that were made with Vegas Video. When playing the footage thru Vegas Video - you can see the footage.

5. Panasonic also has some P2 browser software.

I believe we have tried that and it hasn’t worked with the corrupted files. Prior to salvaging the clips thru Vegas Video, we were unable to view the clips once they were off the P2 cards.

If you have the footage in Vegas you can export to DVCPROHD quicktime format using Raylight Encoder Pro. It will be recompressed but the loss in quality will probably not be noticable. The file will be editable real time in FCP but you will lose the timecode.

Raylight for Windows has an application called Raymaker, which in some circumstances can extract BOTH audio and video from the video MXF file.
This works only with some formats like 720p60 (not 720/24PN) and 1080i60. It outputs AVI format but this can be converted with P2 Maker to MXF. You will lose the timecode most likely.
 
I really want the footage to stay uncompressed. I was told a solution is to:

[FONT=Times New Roman, Times, serif]Thru the Vegas Video program, I need to take footage and lay it off onto tape thru a SDI format (not using a firewire or compressing any footage). This footage can then be recaptured and reloaded back into the hard drive in a format that Final Cut will recognize.[/FONT]

[FONT=Times New Roman, Times, serif]Does this make sense?

This is the response I got from a friend of mine - Does it make sense?

A friend of I've had a similar problem and the way I got the file into FCP was by opening the .mxf file in the Video folder using Quicktime Player then Exporting it out as a .mov file. Quicktime player will open DVCPro .mxf files directly... FCP won't. QT player will only open the.mxf files on a machine that has FCP 5 or higher installed.
