The Panasonic G1HD | GH-1 Video Mode : A Real Video Mode

On the microphone subject... You all might want to be aware that panasonic uses a 4-pole 2.5mm plug for the shutter/mic input...

I'm going to guess that the 1 and 2 position are the audio channels since I've tested it for the external trigger and it uses the 3 and 4 pole for that... 4 is probably the ground.

I'm with you on that, but remember these 3 lucky fellows have only had their cams for a few hours. There's a remote possibility a yet unknown button press or menu item combination might yet yield live video even during recording. At least we can hope! :happy:
 
Philip should be able to tell us once he fires his camera up. if he's willing to go that far into explaining menus and all that. If not, it's all good!

RIght now i'm trying to figure out this bitrate thing.
 
At least you can view pre-record to set up a shot. Kholi how good is the viewfinder? Do you think a hoodloupe/eyepiece over the LCD would be a big improvement?

Does it come with a microphone, or is that something you have to order separately?

The mic in that picture is an accessory that Panasonic is introducing with this camera, that you buy separately. The look of the mic on the flash shoe is growing on me a little.

If one were to hack an external trigger together, what is the signalling? as I understand it on the G1 there's both a "partial button press" and "full button press" so that you can cause it to focus and then take a picture. How are these two states communicated over the third pole, if the fourth is ground? Do you know?

I was just looking at the flower/forest footage and there's no jello with the leica lens. Lots of operator induced camera shake but the tree trunks are rock solid.

This is getting addictive, just like the D90 days all over again. Recently I've been ignoring the rest of the site in favour of the new GH1 section, and now I'm ignoring the section in favour of this particular thread, refreshing the page to see the very next comment! God, I must get a life, but what would I do with that life if I wasn't reading this stuff...!

It looks for different resistance through the same circuit (poles 3/4):
--2k ohm is trigger (or "full button press")
--5k ohm is focus (or "partial button press")

Again I'm guessing this is why panasonic used the 4 pole... reserving the 1 and 2 pole for the microphone

This is different than most trigger releases that use three poles and completely close the circuit (no resistance) on each pole to trigger 'half' and 'full'.

Well, we are now discussing this at the speed of chating... :furious3:
I haven't seen any such speedy forum before.
 
Somewhere in this thread someone asked about time-lapse on the GH1. I believe the answer was that you needed a timer remote controller, or something like that?

I was looking at the G1 accessories on B&H. I don't see a timer controller.

Anyone know where I can find one for the GH1?

Brilliant! That's a really useful piece of information. Since this is the same remote that the G1 uses (well, the model number on the GH1 accessories page is the same as the model on the G1 accessories page), it looks like you can't trigger video recording with the remote. Though its possible that the GH1 looks at other resistance values and 7k or 10k ohms might be equivalent to the video button being pressed -- if they intend to release an updated remote at some point.

ebay. search: "g1 timer"

I've been shooting timelapse with the G1 since January :happy:

The news that it will shoot 1080p till the card is full is like music to my ears!! Great for short term and the trigger works for long term.

I'm ruminating on a project idea that involves time laps and my plan is to create a computer controlled intervalometer using the remote shutter info that upshot just gave. I need variable timing for my project, so something off the shelf likely won't work.

The camera supports a timer but its not clear yet whether this will allow it to take a constant series of shots-- every 2 seconds or 10 seconds or not. Looking at the specs it implies that it will only take three shots max on the timer.

Quite possibly the 2k resistance value it looks for is actually ("anything less than 2k") and thus an off the shelf intervalometer that closes a circuit at a given rate can be made to work... or if not, just put a 2k resistor in line with the intervalometer.

No this is not true. It's looking for the 2k signal. I tried to use an 'off the shelf' timer and simply connect the correct poles and it didn't work. I had to put a resistor inline. It was easy enough after a trip to 'da shack' and some soldering.

It's definitely a cheaper route though if you already have a tc-80 clone with a 3 pole 2.5mm... female 3-pole 2.5mm + 2k resistor + male 4-pole = done for under $10
