New GH1 firmware... June 22nd.

so im worried about updating the firmware as it is ONLY listed on this japanese site. is there a reason its not yet on the american panasonic site?
 
Just updated both body and lens firmwares on my PAL model (UK), and seemed to go fine.

Shot a quick test video in each mode just to see if there was any change to the AVCHD data rate, but after running it through a demo of Elecard StreamEye it looks like there's no change. Oh well, at least Panasonic seem to be willing to release firmware for it fairly swiftly...

Out of interest, what is the 1080 GOP settings for the US model? I was surprised to see that the PAL model is an I frame every 13 frames. The 720 mode is an I frame every 25 frames

Anyway, here's the results from Elecard:

ble for me, so I wait and hope that Panasonic can fix the 1080 video mode.

BANDING: I do see banding in a handful of shots, mostly underexposed shots that have been "pushed" or long exposure shots. Hopefully Panasonic can improve or eliminate the banding but to be honest, every dSLR I've ever owned has had that problem to some degree. I don't see it as a showstopper.

I remember the G1 had banding issues as well.

It could be a RFI issues that's why the fluctuations as well.

Or simply the Cmos needs to be broken in with heat up and cool down over a short time; kinda like tempering. Maybe not, that sounds wacky. Ignore that!


I did however find this blurb from DPreview.com:

<<<<DPreview found in the L1 (?) review that two shots taken in succession of the same subject were different in that one of them had banding. They identified the source to be the mobile phone the reviewer carried.>>

Doesn't seem to affect anyone. Don't take this to the bank but I don't think firmware updates normally affect language... just the underlying code.

It would look exactly like 25p. And no, you're not limited to 1/50, you could use faster shutter speeds, or slower (down to 1/25). No slower than 1/25 though.

For a filmlike look, 720/50p @ 1/50 and throwing away every other frame will look absolutely identical to 720/25p @ 1/50.

Presumably the only downside of this is that you're wasting some of your bandwidth on information that gets thrown away. If you could shoot true 25p at the same bitrate it should look better shouldn't it?

Personally I like the option of being able to do slowmo so shooting 50p is great.
 
what speed for shooting at 720P with GH1 ?

what speed for shooting at 720P with GH1 ?

Hello
What is the best speed for shooting at 720P with GH1 ? 1/50 or 1/100 ?
Thank you
 
Can someone shed any light on how to enable the slower shutter speeds in movie mode post firmware update, because I ain't a clue!!

I thought, okay let's stick the camera in creative movie mode, put it in S mode, change to MJPEG format, change shutter to below 1/30...and...oh.

Still the same as before, won't go below.

Am I missing something here? By the way, I have the Japanese model.
 
works only when exposure mode is set to M, focus set to MF.
does not work when Rec Mode is set to AVCHD and Quality FHD.
So it works only with SH and MJpeg.
 
I should like to update my GH1's firmware.
Is the firmware for the PAL (50 Hz) model the same that for the 60 Hz or are they different?
I need a secure link to download the 50 Hz firmware and I don't find
Can anyone help me?

Thanks

Gary
 
The 1/2 shutter speed is manna from heaven where night timelapse footage is concerned. Low light performance at that speed should be incredible.

Speed it all up in Final Cut Pro and there you have it.
 
hmmm

hmmm

works only when exposure mode is set to M, focus set to MF.
does not work when Rec Mode is set to AVCHD and Quality FHD.
So it works only with SH and MJpeg.

ohh another hidden "feature" so to sum it up:

OIS improved ?
slow shutter only in low res mode?
batteries stop working?

why should I do this firmware update?
and the biggest question for me: can I roll back to the previous FW ?????

where is that FW hacker from Canon :Drogar-Love(DBG):
 
Can i use the gh1 as a sd card reader to copy the new firmware or do i need a separate sd card reader? i'm on a mac, and i don't have a sd card reader.
it's not clear on the panasonic website
