GH3 Corrupt MTS Files

I've been shooting weddings with GH3's for the past few months, and something I'm noticing is that I'm getting 1 or 2 corrupt clips on each card. The problem always happens when I try to bring the clips into Premiere -- it will either import the clips without audio and with horrible green blocky artifacts all over; or I'll simply get a message from Premiere saying that the file has a header error.

Is anyone else running into this problem? Is there a way to restore these files? The strange thing is that they play fine in Windows Media Player.

I'm also using good Lexar/Panasonic/Sandisk SDHC cards.

Re: GH3 Corrupt MTS Files

Just to clarify the solutions I've tried to repair the clips:

1. No Adobe program will open the clips, as I thought I'd just take them into After Effects and render them out again.
2. Panasonic offers a few recovery apps, none of which benefited me at all.

I finally found a program that will open and export to a new working file -- a video conversion program called Handbrake. It's not ideal (as I would just like to simply repair the original clips), but it works.

Drop Lexar from that list, not quite a "junk" brand but not one of the better ones either. Panasonic might be OK but the only ones I really trust are SanDisk.

Also check your card reader, the only time I had a couple of corrupted files was when the multi format media reader on my computer was going out. I replaced it with an external that plugged into a USB port and that worked fine.

Thanks Bruce, you may have nailed the problem for me. Up until a couple days ago, I was convinced that I was just buying crappy card readers, because they always performed intermittently -- they would randomly lose the connection with the computer, often in the middle of transferring. But I just tried swapping the ports I connected them to (from the USB 3.0 ports to USB 2.0 ports) and now the card reader is performing perfectly. Leads me to conclude that I have faulty USB 3.0 ports. And that totally makes sense that an intermittent drive could corrupt some files during transfer.

Funny thing in my experience is that the only brand of card that has caused a corrupt card -- as in, the computer can't read the data and you have to run recovery software on it to recreate file/folder structure -- is Sandisk.

Re: GH3 Corrupt MTS Files

I wonder if changing the card reader will help. Please keep us posted. I've never had a corrupt file, thank goodness. It will happen, eventually, I'm sure, but I will know at least to try changing the reader to see what happens. Luck Corey.

I've been through 3 card readers already, each more expensive than the last, haha. Thanks Jeff!
