ive done it. yes in a 24p timeline. i could post footages of a 1/60. the motion blur of a 1/60 is too much.

Look at it this way. A film camera can't do a 360º shutter. It can go narrower (faster) than 180º, but not slower. So when a film crew overcranks to 60fps for 24 fps playback, they are most likely using a 180º shutter, or 1/120. It's possible they could use a faster shutter (90º would be 1/240), but not a slower one. So for the filmic look, do what film does, 180º shutter when overcranking to 120 for 24p playback.
You are welcome to your opinion, but I am not arguing opinions, I am stating facts—this is how film cameras work, and I have done this myself, both on film and video, so I can say for certain.

I'm not disputing the technical details. I realize that in film, the shutter angle would have to be 180º or less. I was merely musing about the proper amount of motion blur. In my opinion, overcranking with a 360º electronic shutter should yield more "correct" results than using a 180º shutter.
But I'll concede that we've all been conditioned to accept a 180º shutter as more "filmic," just like we've all been conditioned to think that 24 fps is ideal for narrative filmmaking. It's not that it's right, it's just the way that it is.

Huh, I see what you mean now. Thanks! Though, I wonder why that is... Need to think some more on this...
Dude, the math is simple: film-look=24fps@1/48
Shot 60fps@1/120, then divide the speed by 2.5, you have 60/2.5=24fps and exposure time 1/(120/2.5)=1/48.
If you shot 60fps@1/60, then divide the speed by 2.5, you have 24fps@1/24, which is not filmic.
However, footage linked by dcloud is not a fair comparison, as both footage were not slowed down by the same factor...
what factor?
i just conformed 60p to 24p timeline.no time stretching or whatsoever thats it.
(selected footage, interpret footage, conform to 23.97, drag to new composition) I did the same procedure on both footages.

Seems to me that the first footage (1/60 exposure) shows less frame per second, you can feel each frame, while the second one (1/120 exposure) is fluid while it should have look more laggy (since each frame has less exposure). One possible explanation is that your cam only record 1 frame out of 2 when shoting 60fps@1/60

What are the audio controls on the GH1?
Have you tried an external mic?

I have testes the beast in Japan today
I have testes the beast in Japan today
I am now in Japan on holidays and a camera shop is just beside the hotel so I managed to test the GH1.
I wanted to record on a SD card but I couldn't as the slot was taped (to bad). I will try to find one tomorrow in Tokyo with no tape.
I must say, that compared to a movie camera, it is very heavy due to the lense (14-140).
There is no auto zoom in/out. I was very surprised at it is one of most wanted function on a movie camera. But to get from 140 down to 14, it is only 1/4 turn on the lense ... but you need 2 hands or a tripod.
The AF is very accurate and lot of options to choose AF mode
The is not indication on the focus ring of the lense. So, it is a bit to turn the ring with no "hard stop" and phyical indication of where you sit.
When shooting at dark areas, the video seems to be OK with no noise on the screen which is a + for me.
This is what I can say and I forgot to test the manual setting of the mic.. It is rather difficult as the current model is only in japanese with no langage alternative

I think panasonic didn't cripple it, they just never thought that any significant number of people would want a full uncompressed HDMI out while shooting. The target market for this camera, much as we don't want to admit it, is holiday shooters who want to produce more "professional" looking stills and video than they have been previously getting from their point and shoots. These people then want to take the camera to their hotel room and watch the video or look at their pictures (in the convenient slide show program which allows you to add music, etc) on the hotel TV.
I think the important technical challenge for Panasonic when it comes to HDMI was how they were going to give the customer a convenient way to add music to their slideshow!
I think it would be pretty eye opening for everyone to go to the Panasonic Global marketing site for this camera. It will tell you the features, and it will give you a very strong perspective on what features Panasonic believes are important to the target audience. I think you might be surprised:
http://panasonic.net/avc/lumix/systemcamera/gms/gh1/index.html
All the rest of the DSLRs shoot movies because someone in the lab said "Hey, we've got live view, lets just record the datastream and call it a video mode!" and the marketing department, always eager for an extra feature box they can check off approved it. Seriously, dropping half the pixels is fine for live view. Nobody cares about jello in live view because your eyeballs will be vibrating in sync with the camera and you wouldn't notice. This is also why there are lack of manual controls-- anything they didn't get by default (because they didn't need it for stills) is lost in these cameras movie modes.
This is why I say the GH1 camera is a game changer. Its the first DSLR that was designed to shoot video. With that intention, they made a new type of lens that is silently autofocuses, the put in the manual controls and most importantly from a technological viewpoint they designed a dual CPU system and a new quad channel sensor. To be honest I'm a little surprised, and I suspect they're a little embarrassed that there's any sensor skew at all. I suspect this is a design flaw due to them being a bit too aggressive and having to back off and suffer some skew to avoid a secondary effect (possibly overheating, but also possibly draining the battery too fast, or something like that.)
The other guys, if they even care about this market, are a year behind, at least. I don't know whether the D90 or the 5D have been huge successes from their parent companies perspective. We get excited, but we may not make a dent in their overall sales. For panasonic its a lower bar to make a dent in their overall sales, and the G1 has been very popular for many of these reasons (a DSLR without the R).
So, while we aren't really the mainstream target market, we are likely to have more influence over them. I don't think Canon or Nikon will take video mode seriously until camcorders start suffering because people are using these kinds of cameras. I think we'll see our next viable contender from Samsung (assuming "viable" requires a price under $3k, eg, not scarlet.) There would have to be someone pretty radical in the marketing department at Sony, Canon or Nikon for them to make a camera like this-- but they aren't even to the point of giving up their mechanical mirrors, I don't think video is going to be important to them until its a totally non-radical thing to do. But this is reading tea leaves, I hope I'm wrong.
Given the target market, that is a bit of a surprise, and I suspect this is due to the complexity it would add to the lens. Are there any SLR lenses on the market with a power zoom?
But this is a feature for us-- it says "thou shalt not zoom while shooting and hope to use the footage!"

I think Panasonic is very aware of the professional and serious projects the GH1 can be used for. I've seen interviews with Panay reps stating that the video mode is geared toward the advanced user or entry level professional.
They of course want your average consumer to buy one too, but with all of the advanced users raving about the GH1, it will make your average joe want one even more. So I imagine Panasonic thought about people such as us as free advertisement for there pretty awesome new product. I think the GH1 will make the four thirds camera system even sexier. Now if they would only come out with a 6-8 megapixel camera with a focus on high ISO performance, it would be a near perfect camera.
BTW: Is there a world wide release chart for the GH1? I'm in South Korea now...
EDIT: one more question: Kholi, are you planning on getting a nikon adapter for your GH1?

...recommendations for lenses?...Oh and BTW Kholi do you work for Panasonic Marketing Dept. because I don't know why but the part of my brain which is usually rational is screaming "By that #$%#ing camera!"?
