Activity Forums DSLR Video Shoot 12 hours straight on a GH2… and no AC

    Jeff, that means the Ninja is essentially– or factually– a real-time back-up device that provides duplicate clips in intraframe (ProRes).

    And as per John, who has discovered with trial and tribulation there is no happy outboard record solution for the GH2, it’s back to the technical issue of: is there a limit on the capacity of the SD card usable in the GH2?

    I may have to buy one to find out– the 128GB unit, such as:

    A little off topic but FYI I tried to use a A/C power supply for the GH2 at a shoot that went over 3 hours and found that the A/C unit threw out so much interference that it completely wiped out the audio. I was using a direct audio feed from the audio mixer board at the event but with the A/C adapter the audio was unusable. Once I switched back to batteries the audio was fine. I was using multiple cameras which allowed me to cover the battery change with video from the alternate camera(s).

    That’s a helpful bit of info! We do want ambient audio.

    The GH2 has a convoluted AC rig from Panasonic that gets bought as an option, as 2 separate items. Were you using an off-brand unit?
    I bought an off-brand battery extra charger for my GH1 and had to literally throw it away; not only did it not charge correctly but smelled smokey in the process.

    It was not a Panasonic brand, rather an off-brand I found on Amazon. It’s fine for still shots and video where the audio won’t be used but useless otherwise. You might try posting your question on the GH thread at dvxuser forum, there are lots of GH users on that site, here is the link.

    Hey Jim was right– there’s good info here towards the end of a thread on the subject of maximum clip length for the GH2:

    Interference from poorly designed, inexpensive AC power supplies is not unusual. It is possible to buy higher quality power supplies that supply clean, well regulated power that don’t produce interference.
