What happens when the battery runs out when recording?

Since the GH2 doesn't have a recording time limit (except for the European versions where it's a tax game), it's great for unmanned lock down applications. Has anyone had a problem with the file integrity when the camera is recording when the battery runs out of power? I haven't been in a shooting situation when this was an issue but sooner or later I expect I will. Hopefully the camera is smart enough to detect that it's almost out of power and then do an orderly shut down. Has anyone confirmed this in an actual shooting situation?

Re: What happens when the battery runs out when recording?

Only had it happen once, mistakenly put in an off-brand battery to record a presentation. Stock battery lasts about 2 hours while recording, this one conked out after about 30min - and of course, no lifespan feedback with the generic batts.

Switched batteries as quickly as possible and continued on. The previous clip closed out and was readable afterwards.

Probably not a bad idea to simulate the situation a few times in the safety of home to verify what happens, and see if there's a distinct risk of clip corruption. I know there is on the Canon DSLR's, but these cameras aren't as widely tested.

Re: What happens when the battery runs out when recording?

Happened to me and everything turned out fine. I suspect they designed the camera for with this scanario in mind. I'm running four cams today by myself, and it's going to happen at least three or four time to me tonite. Hopefully it will be fine.

It happened once to me and the file was corrupted. The second time the file was fine.

Re: What happens when the battery runs out when recording?

I've had clip corruption with both battery out & card full - I throw another card & a fresh battery in if I'm expecting to let it roll for any length of time. 3rd party batteries are crap even Pearstone from B&H

Re: What happens when the battery runs out when recording?

It happened to me tonight. Corrupted file. I ran diskcheck on the card and it fixed it! (Thank God). Apparently you can spend $200 on a 32GB card and it will have issues the same as a $60 one.

I turned off the power a couple of times without stopping the recording, which isn't quite the same thing, but both times the camera very kindly wrote to the card without problems before shutting down.

DMW-DCC8 DC coupler has been on back order for months, no sign it will become available. Where can I find one Alex? Do you know?

Re: What happens when the battery runs out when recording?

Jeff, not so long ago I called one of the stores looking for the AC adapter DMW-AC8 for the camera, they had both the coupler and adapter (and also a OEM battery) in stock. As I was placing my phone order, I asked how come they showed none on their website. The sales guy smiled and said they did not want to be sold out instantly - or something like that. So may be spending some time on the phone could be a fruitful investment of your time :-)

Re: What happens when the battery runs out when recording?

Thanks Alex, I'll try calling around. I've had one on backorder at Adorama since February 13.

Re: What happens when the battery runs out when recording?

Good luck finding one Jeff. I've been trying for months. Finally went this route GH2 GH2 Power - specs, tests, DIY
Works pretty well.
There are some on e-bay from China (or somewhere) but I refuse to pay $50 for something I 'could' get for $14.

Mark
if you do manage to find some at a reasonable price shoot me a PM...would ya!! Also there is an ac-dc power supply from amazon that works perfect and is only $12 if you want to go that route....much cheaper than the pany one.

The DIY is interesting, but made of wood! That's hilarious, and shows how desperate we are! I will let you know!

I'd order this in a second if I could A) find a DCC8 and B) see how you're mounting the battery adapter plate to the camera. I have so many otherwise unused Sony NPF batteries I could run my GH2 for weeks.

Is that slide-in bracket threaded for 1/4" or otherwise for affixing undercamera or to a shoe mount? Does the battery bracket have a solid mechanical release to securely hold the battery regardless of position or jarring?

Re: What happens when the battery runs out when recording?

Yes, there are 2 1/4" holes in the bracket. The plate itself holds the battery with a semi permanent lock, for what you have in mind probably not strong enough honestly...
Here is an example http://www.dolgin.net/exv-extra.htm of using the plate/bracket with another camera and nanoFlash. It is not exactly the same as GH2 configuration might be, but will give some ideas
