This is quick and dirty, temporary, and by no means definitive. This is just a stop gap until we can put together something more official.

NOTE: THE FOLLOWING IS BASED LARGELY ON SECOND HAND EXPERIENCE, CONJECTURE, AND WILDY HELD OPINION. IT CAN ALL CHANGE TOMORROW AND MAY BE INACCURATE. NO ONE HAS CONDUCTED CONTROLLED TESTS WITH THIS BRAND SPANKIN' NEW CAMERA - YET.


Can you buypass the AVCHD codec by recording out HDMI?
No.
Can you live monitor out via HDMI or any Composite Output?
No.
Can you playback via HDMI or Composite?
Yes.
What are the frame rates / modes the camera shoots in?
1080 24p AVCHD
720 60p AVCHD
720 30p MJPEG
Can I put my old manual lenses on it?
Yes with adapters. See this DVXuser thread:
http://www.dvxuser.com/V6/showthread.php?p=1638227#post1638227
The GH1 is micro 4/3rds camera. Panasonic sells a 4/3rds to micro 4/3rds adapter. Then you have to get another adapter to connect your lens to the 4/3rds adapter. You can get these type of adapters on the panny website or here:
http://cameraquest.com/adp_micro_43.htm
ALTERNATELY you can get adapters that go straight from your old lens to Micro 4/3rds on EBAY. Nikon direct to micro 4/3 (and maybe Canons?) seem to only be available outside the USA right now so expect a bit longer shipping.
What kind of Media / Cards do I need? SDHC Class 4 or 6. Don't buy into the hype and spend twice the money on something you don't need. If you format the card properly / don't have footage from different cameras on it already, it will be plenty fast. If you want faster download times when dumping to your computer then you can spring for the more expensive cards. But you don't need them to record to.
We have reports of working with Class IV no problem. I picked the middle ground and use Class VI though it appears this may not be necessary. You def. don't nee the super expensive extreme cards regardless of what the salesperson says, unless, again, you want lighting fast download times.
Can I record Audio to the Camera?
Yes and no. Yes you can. No you shouldn't. Right now there's no way to disable the audio gain, so when things get quiet the sound will ramp up with a hiss. Most folks are looking at the Zoom H4N ($300 - $350) a small portable recorder whose capabilities blow away any in camera audio recording, DVX to Red. You can get the Zoom H4 for about $100 cheaper it also has phantom power, and may be easier to camera mount with less handling noise (link (http://www.dvxuser.com/V6/showthread.php?t=174994&highlight=Zoom+Mount)) and still has better audio than any video camera - Mino Flip up to the Red. Preamps and other features are better and more numerous with teh H4N

Also there's the Beachtek DXA 5D. It's designed for the Canon 5D MARK II which has the same audio problem, comes with nice XLR inputs and VU meters and solves the problem by emitting an inaudible high pitch toned that tricks the auto gain of the camera into a constant level.
UPDATE:

To connect a BeachTek DXA-5D external audio mixer to the GH1's mic input, a specific plug adapter is required. There's one from Radio Shack which works:

The BeachTek DXA-5D essentially "disables" the GH1's audio auto-gain (AGC):
http://www.beachtek.com/dxa5d.html
What does this camera do that other DSLR's don't?
Cost half as much.
1080 24p
Auto focus in video mode.
It has a quite lens so it won't mess up your audio as it adjusts.
Virtually no jello or skew in 1080 24p less in 720 60p and less in 720 30p.
What's the downside of this camera?
While it's too early to make any definitive conclusions there appears to be a problem of "Mud", macro blocking, during medium speed pans with high detail in the 1080 24p AVCHD mode. The issue seems to be apparant as well in the 720 60p AVCHD mode, though to a lesser degree. In 720 30p MJPEG however, it's non existent One workflow to consider would be as follows:
Shoot 1080 24p for your wow resolution moments
Shoot 720 60p for sequences with more movement
Shoot 720 30p if you're having a problem with mud or macro blocking.
Conform the non 24p stuff to 24p in post, throw on a 24p timeline of either 720 or 1080, mix well, enjoy.*
*Some have suggeste that conforming frame rates in post is not so simple and can be in inconsisent science, especially going from 30p to 24p. 60p to 24p may be more consistent. But Mark II people have been shooting and conforming 30p to 24 for a while.
**UPDATE:60p can be conformed to 24p near perfectly, though painstakingly via compressor. 30p to 24 is another story. Some stutter will likely be visible with 30-24. This will be more noticeable when filmming a smooth moving subject like a car or a hockey puck and varying degrees of less noticeable when filmming a more erratic subject.
How do I remove pulldown in post?
Look for Isaac Brody's stickies in the workflow section.

(http://dlc.panasonic-europe-service.com/EUDocs/)
Does the GH1 have a maximum AVCHD video clip length?
Yes and no. GH1 cameras sold in EU countries are limited to a maximum AVCHD video clip recording length of 30 minutes. GH1 cameras sold everywhere else are limited only by the SDHC memory card capacity; e.g.: can record for hours at a time on AC power or until the battery goes dead.

The Gh1's MJPEG recordings are limited to 2GB (see p.107 in the GH1 user manual).

Caution: According to the GH1 user manual (p.25), a power failure during recording will prevent the current clip from being saved.

No.

^-- Didn't somebody mentioned you can monitor over composite low res but not during recording

What are the frame rates / modes the camera shoots in?
1080 24p AVCHD / 720 60p AVCHD - NTSC model
1080 25p AVCHD / 720 50p AVCHD - PAL model
720 30p MJPEG - NTSC & PAL model


Can I record Audio to the Camera?
it was designed for the MII and it remains to be seen as to whether or not this thing will work with the three ringed audio input of the GH1, could be another good alternative though.

^--- I think Super8 has gotten this to work with the Beachtek DXA 5D

[Not specific to the GH1, but relevant.]:

Q: How can I reduce motion-induced compression artifacts in the video I shoot?

A: Stabilize the camera! If hand-holding the camera, when possible use the viewfinder instead of the LCD: press the cam against your head, press your elbows onto your chest, and breath slowly (or hold your breath). Or: Lean against something inert such as a wall, door frame, lamp post, parked car, etc. Or: Set the camera on a sturdy table or similar surface. Or: Use a tripod, monopod, "steadicam", jib, etc. In general, to reduce motion-induced compression artifacts, keep the camera stationary, or either move the cam very slowly or very fast. Pan less! Tilt less! Zoom less! Sometimes, less is more.

Also: Use a "180 degree" shutter speed: For example, if recording at 24fps, set the shutter to approx. 1/48th-sec. to slightly blur moving details in the scene. Use depth of field control techniques to create a scene with shallow DOF so foreground/background details are out of focus & thus easier to compress. Use lighting & exposure control to force unimportant areas of the frame to easier-to-compress large areas of dark/bright. Motivate camera moves by giving the audience something to "follow" -- such as an actor walking -- so they don't notice compression artifacts elsewhere in the frame. Use diffusion filters, smoke, fog to soften detail and make it easier to compress. Use composition & framing to make the audience look at something in the frame which is relevant to your story instead of a weakness in the medium. Avoid high-detail scenes in which "everything" in the frame moves, such as wind-blown trees & grass, water, and so forth, or use the techniques mentioned here to minimize the fine detail or distract viewers' attention from it.

Efforts to reduce motion-induced compression artifacts recorded in-camera will also reduce compression artifacts introduced further down the production chain. After being compressed in-camera, the video you shoot may be compressed again when captured into a computer editing application or when transcoded to an editing codec. If not edited in an uncompressed editing environment, the video is compressed again when effects, transitions, fades, and color correction are applied. It will be compressed again for DVD, BluRay, web, iPod, and TV broadcast/cable/satellite distribution. Every time your video is re-compressed, your efforts to reduce motion-induced compression artifacts in-camera will noticeably improve the resulting video quality.

Q: Are there recommended camera pan/tilt speeds to reduce motion judder when shooting at 24 fps and other relatively slow frame rates?

Yes, the American Cinematographer Manual covers this in detail.

Ah, the mud has been mentioned in the FAQ despite no actual controlled test of this actually being posted. Let the pointless posting begin
READ
the first sentence of the FAQ regarding mud.
PLEASE.

8. What's the downside of this camera?
While it's too early to make any definitive conclusions ...
I'm perhaps the BIGGEST advocate of NOT declaring the sky falling until real controlled tests by professionals that are maintaining consistency in testing, changing one variable at a time, have been conducted and conclusions drawn there upon.

There does however appear to be SOME kind of issue. How severe, whether it's user caused, defective camera caused, typical of cmos in general, controllable, avoidable, work aroundable, etc, is all up in the air.

Also it DOES say HOWEVER in the MANUAL that if you pan to quickly the image will break up. It also DOES say that AVCHD modes are for HDTV's and MJPEG is for the internet.

In case that sentence is lost, I added an all caps disclaimer at the top of the first post.

I also stated that this was a
TEMP
FAQ
hastily hobbled together at the request of the members because so much information is coming in and getting buried in long off topic threads.

First Sentence as it appeared when you read the post:

This is quick and dirty, temporary, and by no means definitive. This is just a stop gap until we can put together something more official.
Based on your post, I've since added an ALL CAPS disclaimer below the previous sentence about the protean nature of the information in the FAQ.

What is the audio recording format and quality?
According to this post, in AVCHD mode the GH1 records audio as "48Khz, Stereo, 192Kbps AC3":
http://www.dvxuser.com/V6/showpost.php?p=1627988&postcount=64

Panasonic says the GH1 uses "Dolby Digital Stereo Creator" to record AVCHD soundtracks. Refer also to:

AC-3 is the technical denomination for the Dolby Digital format.

In Kholi's Mjpeg samples the sound is uncompressed 16KHz.

Hi Jack, thanks for taking the time to put the TEMP FAQ together, very noble.



Also there's the Beachtek DXA 5D. It's designed for the Canon 5D MARK II which has the same audio problem, comes with nice XLR inputs and VU meters and solves the problem by emitting an inaudible high pitch toned that tricks the auto gain of the camera into a constant level.


Do you know if anyone has posted samples of dialog recorded this way?
And since there is no limiter in the DXA-5D, are there recommended settings so clipping is less likely?


AC-3 is the technical denomination for the Dolby Digital format.
In Kholi's Mjpeg samples the sound is uncompressed 16KHz.

Hi Martti, Have you got a link for Kholi's samples?
Also, do you know if Kholi used the beachtek 5D?

Martti Ekstrand
06-11-2009, 02:26 AM
The only one so far I've seen mentioning actually using the Beachtek is Super8 and I haven't seen any samples from him.

If Kholi's samples are still up the link is buried somewhere in his huge thread, doubt he used a Beachtek, sounds like the built-in mic and it was only a quick test to show the image look of the mjpeg (or rather PhotoJPEG) mode. Only some outdoor ambience sounds in them.

Martti Ekstrand
06-12-2009, 02:33 AM
No, there's a AVCHD 720/60p mode in NTSC and 720/50p mode in PAL. As noted above in this thread.

Does the camera support 5.1 surround sound recording?

Martti Ekstrand
06-16-2009, 04:30 PM
As the onboard mike is only a stereo one I somehow doubt it. Full 5.1 surround tracks are rarely if ever recorded 'naturally' but created in sound post production and mixing.

I know other posts in the forum related the type of SD card you can use with the GH1 (a little bit everywhere in the forum :) but it could be useful to add this information in this temp FAQ

I'm shooting with Sandisk Video HD sdhc cards that have a class 4 rating. Cheaper than the class 6 cards, lowest price currently at B&H is $20. So far no problem.
Here's a link (http://www.bhphotovideo.com/bnh/controller/home?O=sort&A=search&Q=&sortDrop=Price%3A+Low+to+High&bl=&atl=&pn=1&st=search&mnp=0.0&mxp=0.0&sv=sandisk+sdhc+video+hd&bhs=t&shs=sandisk+sdhc+video+hd&ac=&fi=all&pn=1&ci=0&cmpsrch=&cltp=&clsgr=)

Longest clip I have tested these cards was 6 minutes at 1080p AVCHD on a GH1 and 1hr 30m at 1080p AVCHD 17mbps on a HF100.

Later today I will test with a GH1 and leave it till the card runs out of space which I am guessing will be over a 1hr continuous clip. I'll post my results then.

EDIT
Hey Jack. I finished that test with a 1hr shot on a class 4 card. Also tested H4 audio sync at the same time. Class 4 cards seem OK but H4 audio drifts. Results are at this thread LINK (http://www.dvxuser.com/V6/showthread.php?t=175358)

Thank you for the very informative FAQ Jack. I've been trying to read almost every post about the GH-1 since it was first announced, but it's good to see it condensed and summarized. I've also picked up some new information I've missed as well.

It's posts like this that make me feel that dvxuser would greatly benefit from having its own wiki. I wouldn't mind setting one up.

..i looked around for abit and figured it would be faster to ask here after a while, but is the AVCHD inter or intra?

..and dang im going to be disappointed if panny fails to make an inexpensive 4/3" ( or larger sensor) HD prosumer/PRO dedicated camcorder with higher data rates after this.

Barry_Green
06-27-2009, 04:17 PM
AVCHD is interframe long-GOP. It's an extended, higher-level HDV. Still long-GoP, still 8-bit, still 4:2:0, but AVC encoding instead of MPEG-2.

Neil Rowe
06-27-2009, 10:40 PM
;) light bulb is on now, thanks. i was thinking that AVCHD could use intra as well (HPX 170)..BUUUT they call that AVC-intra to distinguish it. i guess i never really realized that two monakers were entirely distinct from each other untill now.

anyway, they really should stick one of these ..or better sensors in a HVX/HPX body though and tie it to a DVCPRO-HD or better format pipeline.

Jack Daniel Stanley
06-27-2009, 11:34 PM
And add a comparable / comparably versatile lens system.

We've got the sensor and the lens in one camera, and the codec in the other. Though AVCHD is supposed to be awesome if implemented well (HMC 150).

I'd be fine with AVCHD if it was implemted as well as the HMC150. With DVCproHD the price will start to climb, beginning with recording media.

Neil Rowe
06-28-2009, 10:28 PM
.. id still rather have intra frame recording though for post purposes. cost would go up with storage for better codec, but it would still be affordable all things considered. ..they should throw in a CF slot and let you use CF or high speed SD to record on though. or external firewire or anything besides only letting you use P2, but really even if it was back to that, id buy it in a heartbeat if it was the same or lesser cost of HVX with cards, and seeing as they can cram it into a little SLR they should drastically shrink the body of the camcorder down to save weight and size as well. id like a little honeywell elmo looking panny with that nice lense on the GH1 and everything nice and compact and light. ..the GH1 is awsome as is, but theres just so much potential for a great cinema camera there if they play the cards right with all this new technology. ..i mean the reds are great, but all the storage issues and such is a little disconcerting. .. not to say im not getting one :), but even the fixed lense scarlet is only 2/3 inch @ 3x the cost (+ other things still needed) of this thing @ 1200, and this is roughly a s35mm format video camera image wise for all practical purposes.. just it would be great to have something professional, small and simple that shoots 1080 or 2k 24p and some 720p at higher FPS in small camcorder package, and does it very very well. thats really all most of us need or want. i think whoever gets it into a small camcoder formfactor first with normal prosumer/pro type control and feel is going to hit a jackpot. do things like copy the input for electronic focus ring off the lense barrel and put it onto a small built in follow focus like wheel that is on both sides of cam with standard crank plug. im perfectly happy with an HVX on a letus EX.. i just want it small and light and low light capeable, and id be good to go. .. and if they can make the GH1 with a street price of apx 1200 i dont know why they couldnt make an awsome little pro cine cam for apx 2000-2500 that boasts better recoding format, XLrs and all that jazz. give us the same ISO selection and features on GH1 so we can use it like a film cam and run and gun and drop and drag into post with.

ive been debating picking one of these GH1s up but i just keep crossing my fingers that they will release some camcorders to follow it up.


..although my wife could use a nice SLR type cam for christamas anyway...so maybe i can just borrow it from time to time untill someone makes an affordable camcorder like it :)

I'm confused about 30p and 60p. Can you record 60p MJPEG? Or is 60p only when you are on avchd?
I thought I recorded a bunch of 60p shots just by having the shutter speed over 1/60th in MJPEG mode...??? But now.. which ones were they? Other than a slate, is there a way to tell which is which when you have the files on the computer? (G5 mac/ voltaic workflow)

Jack Daniel Stanley
07-14-2009, 08:18 AM
Tim, do you have a users manual,lol?
As stated there and in this thread you have three shooting modes:
1080 24p AVCHD
720 60p AVCHD
720 30p MJPEG
Shooting at a shutter of 1/60th in 30p MJPEG mode will not give you 60p MJPEG anymore than shooting 1/120th would give you 120p MJPEG.

If you shoot 60p AVCHD at 1/50th or slower it will force the camera into an undesirable hack where it gives you doubled frames essentially creating 30p in a 60p wrapper just because you can't have a shutter speed lower than your frame rate (that would mean a shutter angle of greater than 360º). But there is no limit as to how fast you can make your shutter speed. Except for what I just mentioned, shutter speed will not change your frame rate.


As for finding them afterwards - MJPEGs are in the DCIM folder. AVCHD is in the private folder.
As for determining whether you have 60p or 30p just bring it into something. QuickTime? FCP? either will note what frame rate you have. If you'd like to know if you accidently got the bad 30p wrapped in 60p hack, then frame by frame your video. If you got the 30p in 60p every frame will be doubled.

Tim Joy
07-14-2009, 09:20 AM
yes I have the manual, but those things are for pansies.. REAL men like me go out and shoot a bunch of high action deathrace footage of guys crawling though mud, rivers, under barbed-wire, chopping wood...etc- thinking I'm shooting some awesome 60p slowmo footage... but not. whoops. Guess that manual could've come in handy there!

Nowhere in the camera menu do I see 60p, so I'm assuming it must be the HD quality setting instead of FHD when in acvhd mode?

Thanks!

Barry_Green
07-14-2009, 09:29 AM
720/60p is available when choosing "SH" mode. FHD = 1080/24p. SH = 720/60p.

Jack Daniel Stanley
07-14-2009, 09:29 AM
Slow mo should be 60p shot with a 1/120 shutter.
60p to be converted to 24p later should be shot with a 1/60.
30p to converted to slow mo should be 1/160.
30p to be converted to 24p should be 1/48 (1/50).

You could put "or above" on any of the above speeds knowing that gives you a high speed shutter look, but to emulate film look most of the time you want your shutter to be double your frame rate. For stuff you are going to attempt to convert to 24p you double for 24p (the exception is don't go below 1/60 in 60p). For stuff you are going to convert to slow mo you double the actual rate you are shooting, because the film camera would also be shooting at this rate if you were overcranking for slow mow and a 180º shutter would be 1/60 on 30fps and 120th on 60fps.

Ahh! ok. Thanks guys. I can't wait to get home and shoot some real slowmo. :) :) The fake stuff was so unsatisfying.

Now, if it weren't for that SLOOOOOOW Voltaic transcode on my old G5 I'd be golden.

Man, if they'd only get uncompressed 4:2:2 1080p24 out the HDMI port I'd buy this camera in an instant. Hook it up to a NanoFlash or Ki Pro and it's golden.

See if you can borrow and HVX or 170 and film your Voltaic transcode at 12fps. When played back at 24ps it should make your Voltaic transcode go twice as fast ;)

That's a really really really really good idea. I'll do one better and use the GH1 and take 1 shot per minute, then it will make the transcode go... ummm Way faster than all you suckers with intel's. Let me try that..... brb





...... oh it WORKS! That's genius! :nads: :Drogar-BigGrin(DBG) Thanks!

At some point somebody talked about which ISO levels are the best to use...and now I am having great difficulty finding that, even with search. Anybody got a lead for me? That seems like info that would be good to have here.

Not sure it pegs "the best" but lots of good ISO discussion.

Thanks alot for putting this FAQ together Jack! Very helpful. Appreciate your machete test as well!

I've got a question. Is it normal that you can slightly turn the stock lens when it properly attached? It moves a little when you turn it clock or anticlock wise.

For example when I zoom in and out and I reach the end points it sometimes rotates just a little. Is that normal?

Or is this just the hvx clunk sound question for the GH1? :D

Don't know about the slight rotation. My GH1 is being borrowed right now. When I get it back I will investimagate.

I know this has been mentioned a few places but should probably be added to the FAQ or some sticky that the camera cuts off the last few seconds of recording...as much as 3 whole seconds, when you cut, so always leave some extra post roll. Out and about shooting montages I can't tell you how much this has messed me up when I maybe got the shot I wanted setup, left it for 6 seconds, and then lost 3 seconds of it. I'm now getting used to it though.

What an excellent thread. The Canon 550D could really benefit from a similar one.

Apologies if this is answered somewhere else, but I have a new GH1 serial # WE0B with firmware 1.2, so it should be hackable. Do I have to upgrade my firmware from 1.2 to 1.32 before hacking? Or can I hack right from 1.2? How do I revert to 1.2 if I want? What is the recommendations here?

Thanks!

Oh and if anyone is interested, if you act fast HENRY'S in Dartmouth, Nova Scotia, Canada has a brand spanking new GH1K (14-140mm kit), Serial # WE0B in stock. ONE ONLY. $999 Canadian. If you hurry you might get it. (http://maps.google.ca/maps/place?um=1&ie=UTF-8&q=henry's+dartmouth+ns&fb=1&gl=ca&hq=henry's&hnear=Dartmouth,+NS&cid=13111700980310243745)
