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

Why Barry haven't got this camera?

Well, Barry actually was the one to lit the fire! After he showed deep interest and gave some early approval everybody really paid attention. Now Kholi is doing some more./ Fingers crossed for positive results from the camera.

but I like to punish myself.

an HDMI output wouldve blown a lot of cameras to smitherins. think about recording on a external recorder in prores or a high bitrate codec.... mindblower!

which is exactly why panasonic crippled it. They would have hurt their pro video division.

Thats a scary thought. With maybe AVC Intra 50 at least. And the price shouldn't even go up. Plus all the lenses in the world? Boy oh boy!

Thing is, if anyone is going to give us a prosumer HD cam with a big sensor and removable lens mount, I'd bet it will be Panasonic. Since the days of the first DVX's they've been the most indie filmmaker friendly out of all the others (Sony, JVC, and Canon). Nikon doesn't have any video cameras to protect, so I'm not gonna hold my breath waiting for them to be the one to answer our prayers. The D90 was a neat little start to this, but the D400 will be a good indicator of how Nikon really feels about video.

As for Panasonic... now with P2 cards being half the cost, why the hell not?

But for now the GH-1 sounds so darn good that it should keep us busy for awhile.

Yup! All shutter speeds are accessible. I was giving low shutter figures for those worried about 1/48

So slow motion is possible in post? I'd love to see a sample of 60p to 24p slow motion, Kholi is that possible this week?

Slow motion is so ridiculously easy with this camera. All that you have to do is use something like Cinema Tools in Final Cut Studio to conform 60p footage to 24p (just changing the playback frame rate in the file header, basically), and then drop the conformed footage into a 24p timeline in FCP. Is the slo-mo too slow for you? Simple fix, just speed up the footage. See how easy getting faux-overcranked 30-60 fps is? You can even slow down the 60 fps stuff a little bit without it looking too fake.
 
Good to hear about the slow motion.

You guys think May is a safe time to sell my D90? Photographers wouldnt care about the GH1, so I figure D90 could still sell for near brand new price, whaddya think?
 
Kholi,

I'm confused by your statement on the first page after number 12. You got the menu working in English? If so, I'm importing immediately.

This is my concern as well... 60p with 1/60 is less than ideal when converting that to 24p slow motion.

Actually, if your plan is to shoot at 60p for an overcranked effect, then the shutter speed that you should be using still would be 1/50. Why? The visual effect of shutter speed, other than on image brightness, is the amount of motion blur. When you shoot at a given shutter speed, that means that each individual frame is exposed for that amount of time; the frame rate of the motion picture is irrelevant.

If you're "overcranking," then the motion blur in each frame should match the motion blur of each frame of regular-speed footage. If you shot 60p footage at 1/120 and slowed it down to 24p, then the footage would look overly juddery and just wouldn't look right when blended with regular-speed footage.

High shutter speeds in cinematography are mostly just useful for action scenes and to get that "Saving Private Ryan" effect.

Just my two cents, anyway.

Am I right to assume shooting at higher shutter speeds (1/120th) IS important if using 60i not 60p, since deinterlacing 1/60th video would look "bad"?

Oh mama I wants a GH1! (No more deinterlacing)

Although, I'd also like to know more about what issues people face with 24p embedded in 60i stream? Is this only a problem for render times in a NLE? Or does it effect the image?

Hard to know how many D90 users bought it to shoot video. Mb Isaac can shed some light on how many dvxusers view the D90 forum

Mine's going on ebay as soon as I see something decent from kholi, hunter, and that other geezer

Sorry to keep asking, but ... :shocked:

Since it's looking like the GH1 probably doesn't have full-time live HDMI output, can you please check ASAP if it has full-time live SD composite video out? :)

It might not be a deal killer for some, but it's a fairly important question for many potential users of this cam.

Thanks!

Funny thing is that I haven't been close to an SD/Composite output yet. LoL.

You guys might find out before I get close to one. This cable seems familiar, though. I think it comes in Component also? That might be a good thing.

You can't shoot at 60fps with a 1/50 shutter. The slowest shutter you could use would be 1/60.

For the filmic look, you want a 180º shutter. At 60 fps, that's 1/120.

ive shot 60p at 1/120 and 60p at 1/60...
1/60 looks horrendous at high speed subjects.
1/120 looked exactly like 24p 1/48

its all in the dv rebels guide

So Kholi, I know you can't give the GH-1 a final grade just yet. Am I close in guessing that so far the only real knocks against the GH-1 are that there is no HDMI out for monitoring and uncompressed capture and the 24p-in-a-60i stream that can hassle us during post?

Of course, these issues are not crippling and it is a massively better situation than the D90. Good news is that when and if Panasonic ever got around to producing an HMC150 or HPX170 style camera with a 4/3rds mount, these two issues would be most likely be rendered moot by then.

Basically we're going in the right direction with the GH-1. The bar has been raised. If the only GH-1 issues are no HDMI and 24p embedded in 60i then Canon, Nikon, Sony, JVC, and in terms of 35mm DoF at a great price... even Red might have some big shoes to fill.

Knocks so far:

1. Kit Lens has an Odd will of it's own on the wide end. Seems to want to still compensate for exposure but you can BARELY tell. You have to look for it to see it. But it's just the kit lens doing that at the wide end, zooming in and out does it.

2. Codec May break up under certain areas of the light spectrum? Does this make sense? Seems like tungsten balance causes more compression noise than daylight. So Lowlight suffers, I think the lowlight is directly comparable to the EX-1.

3. No HDMI Live/Live HDMI output

4. Can't Snap a Photo During Movie Recording, or at least I have that option turned off or something in MOVIE MODE. You CAN do it while recording in any other mode. I might have an option turned off or something.


When someone more efficient with Compression and how it behaves gets ahold of it we'll know more about compression. Right now, I can say that it's leagues ahead of the D90.

As an entire kit the bar HAS been raised. Regardless of who wants to hear it or not. The damned thing with a slow zoom on it is ready for action, and only people who are looking for reasons not to shoot will whine.

If Panasonic did this at 1500.00 Street Price, then the rest of the MAJOR manufactureres MUST respond and match or beat it. SCARLET's an afterthought over here.

Never mind my post then. But my question is were you playing that 60p back at 24 fps, or at 60 fps? I would imagine that 60p at anything slower than 1/120 would look odd.
