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

I dont know but this looks pretty good to my eyes. The guy won't shoot straight but the footage shows how the camera adjust to different exposures in and out the house. And I like the colors a lot. And the fact is that when you shoot a movie you plan your shots. Your angles, your background, etc., etc. If you know what the camera can and can't do you have to adjust accordingly. Thats just common filming sense. In addition each take shouldn't last more than seconds, so you have to really be careful about those seconds at a time and you have to make sure they are shot under the best conditions your camera would allow. When you are doing documentary work that might be a different story but you can also work within your camera limitations and make it look the best allowed by it.

These ones are interesting too. The guy can't shoot for crap but you can see the camera working pretty fine under the circumstances:

JC, whilst the footage, the HD versions, contain generally impressive resolution and detail, it appears that most of the footage on the tube or vimeo are being recorded with fast shutter speeds, and may not be 180 degrees. The footage tends to look more like video, unless you are shooting a scene from 28 Days Later with a dozen zombies chasing you down the street. GH1 users may need a few ND filters in their pocket for outdoor shooting, especially if using fast glass at say f1.4/wide open for a pronounced DoF shot.

Thanks for the links, JC.

Amen, brotha. It indeed comes down to mastering the device and using it with intention and control.

I've been impressed and depressed by the footage I've seen, but that happens with every camera. I think of this just like all other tools, technologies, and methods I've used - from guitars, effect processors, recording gear, software, computers, web standards, video distribution standards, to microphones, video cameras, and lighting.

The process of achieving any artistic vision and excellence with technology involves knowing nearly as much or more about what makes things horrible.

As much as some may feel this is a lynching of the product under torturous tests, is because that is crucial to learning what you don't want to do with the camera.

That's why when the HVX200 finally arrived in my hands, I had already come to terms with all the "horrible noise, and terrible low light performance, and crappy resolution" - all of those things can be said about the camera. But far more positive things can be said about the camera and the people who have made awesome gorgeous motion pictures with it.

I am continuing to get a solid sense of how I'd use the camera (GH1), and just as importantly, how I would not.

I have to disagree - just search aliasing on the Mark II on Youtube or Google - horrible stuff out there, way worse than anything we've seen on the GH1. I would say it a factor of 3 or 4 times worse than the GH1, if not more. The higher resolution sensor and slower processing sensor on the Mark II are probably factors.

The real factor is the third pixel row issue (instead of resampling full-res picture it takes every third pixel row). But there are workarounds for avoiding it.

Kholi, did you have any chance to test them with the GH1?

By the way, is the aliasing the major GH1 flaw @1080/24p in your opinion?

I've seen the Philip Bloom stuff, it doesn't seem bad at all. No raw though.

I shot video with a 5Dm2 and now having the GH1, I can promise you, the aliasing on the Canon is just about the worst case of aliasing I have seen on any camera ever. It doesn't show up all the time but when it does its horrid and there isn't much you can do about it.

Any aliasing in the GH1 footage is so slight that you have to be actually searching for aliasing to see it, (with the 5Dm2 - it screams out at you) a good comparison would be to shoot the exterior of a building with a lot of fine details (like bricks or siding) and use a wide angle lens, with both the 5Dm2 and the GH1. But I can already tell you that the GH1 has aliasing way more controlled than the 5Dm2.

it's clear to me that 17Mbps is plenty of bandwidth and all the talk about 1080 being bad is way premature.
Click to expand...
If 17 Mbps is enough for long DOF shots from say, Canon HF100, it should be enough for shallow DOF shots from the GH1 simply because blurred image is easier to compress.
LizaWitz said:
If you ramp exposure like that in 720/60p, the compression will break down just as bad, probably worse.

Maybe the exposure issue is due to some bug in the code when the camera is in 1080 mode and that's why you're not seeing it in 720.... that's quite possible. But its not intrinsic to the compressor or to 1080.
Click to expand...
This should not be a compression issue. Older-tech MPEG-2 @ 19 Mbit/s works fine in JVC HDV camcorders, therefore there is no reason to think that potentially two times more efficient AVC would not work @ 17 Mbit/s.

Is this applied in particular to the 720/60p or to the 1080/24p footage as well? Same amount?
 
I am sure that Panasonic, with billions of dollars in the bank, and powerfull R&D departments should know what they are doing in regards to implementation of technology. After all they have to make sure the technology works properly, it is their company's reputation and survival on the line not ours. We have the choice of buying their cameras or not, they have no choice, they have to make sure they sell and work.

Look at it this way, I'm going to buy one for $1500, use it a year and sell it for $750 on eBay then buy the GH2 or better small stealth cam when that happens. It'll cost me $750 for a year to shoot on this little cam, it will pay for itself in half a day maybe 30 min.

And that pretty much sums it up. These cameras are now so cheap that how can you afford not to get one? If you're in the business, any of these cameras (HPX170, HPX300, EX1/EX3, on down to the GH1) should pay for themselves in a month at most.
 
Barry, Ijust shot something on the HVX 200 at 720p60 and dumped it on a Edius 5 24P timeline and the output looked very good and "filmic" on a DVD. I would like to know exactly whats going on here. What would be the difference and the use of having to shoot 24P straight up then. Thank you in advance.
 
Shooting 24p straight up would give you the optimal use of bitrate, and you could use a shutter slower than 1/60, such as 1/50 or 1/48. The motion would also be perfectly conformed to 24fps.

Remember back in the DV days, if you were shooting using an NTSC camera for film transfer, 60i was always recommended over 30p.
 
But I've read here that the 720p60 MJPEG is doing 26Mbits/s or something like that, higher than AVCHD. Would that make any difference? Again, sorry for ignorance on the subject, this is something new for me, but why you can't shoot at say 1/50 again?

Hunter,

I disagree. There are workarounds. Did you test anyone?

E. :-)
 
What are the aliasing workarounds on the 5D MKIi Emmanuel? Mine just arrived this morning, going shooting in the next day or two.

Thanks,

Dan

We're getting really off topic here, but I've identified the biggest offenders for causing moire and aliasing, and my solution? Simply avoid shooting those types of things. Mainly it's fine horizontal lines on anything - I am glad that I can pretty easily see the problem on the 5DMkII and reframe the shot to prevent it.

Back to GH1 topic - I am pretty sure there is some amount of aliasing going on as well, and it will be smart to identify the worst offending type of shots on this camera as well, and then avoid them.
