Hacking the GH1 to record RAW???

Does anyone know if any groups or individuals are planning to hack the GH1 to output RAW directly from the sensor (kind of like the Andromeda project for the DVX100)? I heard a rumour that a group in Ireland are planning to hack the GH1; any details?

And/or does anyone know who makes the GH1's sensor? Is it a Sony sensor? Or did Panasonic design and fabricate it? (I have no idea if Panasonic have fabrication facilities).

It seems to me that a GH1 recording compressed RAW (like Cineform RAW) would absolutely rock!
 
Jack - you keep popping up everywhere - we aren't the only ones thinking this surely - so how hard can it be to gain some momentum on this.This rumour you heard.................any idea who it is referrring to?The GH1 is a perfect candidate - less rolling shutter,24p,interchangeable lenses,large sensor - I mean,RAW out of this thing would be amazing.The guy who is hacking the 5D,
Hudson I think, really ought to have a look at the GH1 and see if he can output live HDMI.That would do for me and I would gladly pay for the privilige.Anyone who can do this will be classed a legend in my eyes..Live sensor readout would be a ton of data but if that can be done then count me in again - this would turn this sucker into a mini RED.

Here is my contribution to this dilemma.I believe that the power of observation is our friend.I will use information From Panasonic themselves.

Check this video of the little non-video G1 cam out guys.....the little brother of the GH1..

http://www.panasonic.co.uk/html/en_...l?trackInfo=true&mmView=video&number=1&size=l


1 minute 24 seconds.Did you see that????It is connected to an HDTV and I believe it may be via HDMI ( 3 minutes 21 seconds ).It may be composite but I don't know.Either way - I went to my local Jessops ( a camera shop here in the UK ) to see if I could get it to output a live signal and guess what - nothing.Twice I have tried to do so but failed.This means that the camera is capable of doing this as shown in this video but we know not how.There is no hiding it now is there?The G1 outputs live video.....but Pana have disabled it for the rest of us.


Perhaps a service manual from a disgruntled,laid off former Pana employee .(Tongue in cheek so no offence intended).Perhaps it is a simple button combination at start up.This would be amazing.Any other ideas....think i am on track here or imagining things.

I'd be happy with the unprocessed 4:2:2 HD signal from the HDMI port. Hook it up to a Nano Flash recorder, and you're set.

'Fraid not! To be honest, I could have dreamt it! I'm 90% certain I read a very brief post here on DVXuser about a group in Ireland who were thinking of hacking the GH1. I've done a number of searches for "Ireland" and "Belfast" here on the board but no joy.

I agree - HDMI out would be a big step up (as long as it was possible to output a "flat" image from the camera with the sensor's full dynamic range represented in the signal). Compressed RAW would just make me jump for joy.

I'm day-dreaming about a little box the size of a Beechbox which you bolt onto the bottom of the camera after hacking the camera to output the sensor's RAW data to a little port on the side of the cam. The box records compressed RAW to SD or SSD and also has an S/PDIF input and dual XLR inputs. (That's a Scarlet competitor right there). Heck, even if a backpack full of hardware were required to record compressed RAW I'd still go for it.

I remember watching this a while back and thinking, great the GH1's going to have a live output. Somebody has got to figure this out sooner or later. If it's accessible for demo purposes then hopefully there will be a button combo golden key of joy somewhere.
 
There is a video on Vimeo that was captured from a G1 - yes a G1. He explains that he holds down the trash button for a few seconds and it switches from the display on the back to outputting to a TV (not HD) Details here: http://vimeo.com/4206790 Could be that is what is happening in the Panasonic video?
 
Yeah, I've never seen that video before but he could be outputting the SD signal to the LCD which you CAN do until you hit the record button.

However, he's snapping photos as well, and I don't think the video on my GH-1 stays on when you snap photos.

The good news: if that Firmware update that's been spat out by Panasonic already will work, then we already have a place to start with the Hack.

The people at Convergent would be a huge beneficiary of HDMI direct output from the GH1. They would make a ton of extra sales.

Well...I've always complained that the nano flash is way too expensive. But if (or I should say WHEN) there is a hack on this GH-1 then the nano flash will be my good friend. At that point it will probably be....Red who???
 
Is a bit expensive but for what it would do with a full HDMI out in the GH1 it would be awesome. It would surpass cameras costing many many thousands more. If you are making money with filmmaking the quality of the output would give you a big edge. Making the investment back would be no problem. And it would fit perfectly on top of the camera too!
 
Kholi,
you have one of these baby's.How about connecting to an LCD via HDMI and pushing the trashcan for a few seconds.Can only try dude...........obviously if one wished to record using an intensity pro or related product then one would not need to push record.
 
Oh I tried, profusely. LoL. Trust me, it's not workin'.

And my GH-1 is gone now for a week or so. =( So sad.

But it's going to good hands. =D

At least you can say you have one! Seriously can't wait for it. Hoping that it comes in June like the Panasonic site states.
 
I don't understand all of the hype around the nanoFlash. The Ki-Pro, though more expensive is ten times more useful for production.
 
Question regarding the KiPro; do the external harddrives that plug into it have any sort of motion compensation like the Panasonic P2 offloader? Basically I want to know if you can throw it in a backpack while you're filming.

I haven't been following the GH1 forums the past couple of weeks since I picked up a T1i. How is the shutter roll? It's horrid on the T1i at 1080 (I know, 20fps is useless anyways). It's also unfortunately very noticeable on in 720 30p in any closeups with motion; that's either at a narrow FOV with the object filling most of the frame, or with an ultra-wide really close so the object also fills most of the frame.
