Help! AVCIntra locks up in log and transfer

[David Coleman] ” I use a PCD20 card reader daisychained to the FW800 drive.”

Okay, so let me get this straight. You have a PCD20, a fw800 drive, and an IOHD on the same bus? how did you have enough ports for that? 😀

I don’t usually import to the database, I simply select all and export of out P2CMS with verify. It keeps the card structure of the P2 as it was shot in tact.

What happens if you try and take the video MXF file that is getting stuck and play it in quicktime? Navigate to the offending video MXF file, right (or option) click on it and choose Open With > Quicktime.

How big is the offending file? If you have ingested via P2CMS, it’s probably it’s own MXF file now, correct? Any chance you can upload a problem file? I’d like to check it out.

We mock what we do not understand 😀

There’s a port on the front and on the back. I may not have explained that the IOHD is new as is the computer, so it explains why I haven’t run into this before.

QuickTime has the same problem. I have one I can send you that is about 34MB. How do I get it to you?

I was thinking this was on a laptop, not a desktop, hence my cornfusion. Do you still have access to the original P2 cards?

[David Coleman] “I have one I can send you that is about 34MB. How do I get it to you?”

yousendit.com is good (and free) if you don’t have a website you can upload it to. Once you upload, just send the link back here.

34MB? That seems very small.

Yeah, it is a short clip. Here’s a link to the mxf file. I can’t upload the contents folder because dropbox and yousendit only allow files to be sent. No access to the original cards.

Simply take the encompassing folder that holds the contents and lastclip.txt and then archive it by right clicking ont he folder and choose ‘Compress’. I need to see metadata and everything. Sorry to make you do it again.

Cool, learned something else now.

Thanks. First off, this appears to be AVC-I 50, correct?

Also, you say you shot 720p59.94, and not 720p30 over 60?

You are right, this is crashing everything once it gets up to that freeze point.

It appears that part of your file is in tact, but the rest is corrupt. It must be the way it was transferred or offloaded, but I don’t know enough yet. Let me look further.

Yes to all your questions: AVC-I 50, 720p 59.94

yeah, it appears that there’s some major corruption on this clip. There is information contained within it, but it goes bad along the way.

Unfortunately, I don’t know what you can do to fix it, but that doesn’t mean there isn’t a fix. I am just not aware of it. Your method might be the only way to do it.

The audio is in tact it appears, if that helps at all.

For next time, get yourself a PCIe fw800 card, and separate the ioHD from the rest of your system. Better yet, turn off the ioHD and put the fw800 drive on the PCIe card and the PCD20 on the internal Mac bus (plug it in the front or back, but not both). Then once the transfer is done, you can use the ioHD again. FWIW, someone else just had a similar problem with daisy chaining a PCD20 without an ioHD. I’d say leave the daisy chaining out of it. It doesn’t seem to be working, and make sure to have the drivers installed for the PCD20. This is just my guess.

I would also suggest in investing in ShotPut Pro. Very easy transfer software that also verifies the transfer process. It’s inexpensive.

Thanks, Jeremy for all your help. I’ve concluded that it isn’t the AVCIntra codec that caused the problems, but copying the files to the FW800 drive while the AJA IoHD was connected to the rear FW800 port.

I’ve salvaged a lot of the footage and interviews and I’ll be doing things differently. Specifically, I’ll be getting a PCIe FW card, though I’d like to get the PCD35 card reader while I’m at it.

Thanks again.
