Panning 'mud', reasons why and firmware update

An interesting result here.

1/30 F4 ISO 100:
Pretty bad...


1/30 F4 ISO 320:
This seemed better...


1/30 F4 ISO 800:
Oh dear, then the theory falls down...


1/125 F4 ISO 320:
Underexposed but fine once again at ISO 320...


1/125 F4 ISO 800:
But if it's higher ISO which solves the problem, this tells me otherwise...


What's interesting here is why the dark one on the fast shutter is so much better than the lighter one shot at ISO 800.

It seems the underexposure has cured the problem. Another test which adds weight to the 'detail' theory.

The more detail in the shot, the more corruption when panning...

Nah nah nah. Not High ISO. But Software driven ISOs. Which ones are the native ISOs is what we have to find out. I'm damned sure 320 is, was sure of that when I started shooting with the camera and I think all multiples of 320 are going to be the right ones.

Thanks for testing this, though! GAHD I wish I hadn't sold my .JP camera. Not having the GH-1 in my hands is KILLING me. The MKii is just sitting in the camera bag right now.

UGGGGHHHHH.

To activate the incremental ISOs, change it to any of the other camera shooting modes, go intot he menu and find the ISO 1/2. Switch it to 1/3.

Then try.
 
I shot some stuff at 130. What's the best way for me to encode it for this test? I have iMovie and FCS at my disposal.

There's a 130 ISO on your model? O_o; What kinda crazyness is that? I thought it went-- 100, 160, 200, 250, 320, 400, 500, 640, 800, 1250, 1600, 3200

Anyway, don't worry about encoding. Just upload the raw MTS file somewhere for downloads.

Make sure to include shutter, f-stop, iso info etc.
 
It's still there are ISO 125 for sure. Less so at 320.

320:

Granted, these are simply screen grabs from iMovie's import. But it does look the same as the previous "mud" examples.

Sorry. 125. I think i jut picked the next one up from 100. I have 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1250, 1600 and 2000, 2500 and 3200 grayed out.

News of the death of the GH1 are greatly exagerated.

What we learned once again: don't do any whip panning. Now, we want to see some "normal" panning if you will. Thanks for the footage.

Again: We know whats bad now we need to see how good.
 
I'm still ecstatic with my choice but I'm just shooting for personal use and perhaps some spec stuff for my Ad Art Director's reel. But I can see how this would be disappointing to some folks. I'm not a big swish pan kind of guy myself so I rarely see this being an issue for me. This cam will mostly be my baby movie camera.
 
They should have all been at 1/30 shutter. It might have been a bit faster but you can only control the speed so much when it's handheld. It felt about as fast as the AVCHD pans I did.

That really does look remarkably better. The blur streaks are much longer in this one, though. Did you pan faster or use a different shutter?

Yeah looks incredibly smooth. I'm surprised at myself, actually, that I didn't do more 720/30P stuff. It looks really good.

1080/24 MJPEG ...mmmm

Which is the clear choice in VDSLRs right now would you say, Pappas?

All I can really think say is what I said on my web site.


""Panasonic has confused me before; however this time it's to bizarre.
Unlike the HVX200 that was an under powered Honda civic trying to be a
Mercedes-Benz SLR. The GH1 was a product with all the right parts to only
be crippled by a horrible implementation of the main codec system.

Good work Panasonic; you sure know how to flat line a new born....... ""

Have you tried the 720 60p to compare it to the 720 mjpeg?

It looks like this camera would work best, as Kohil suggested, if you used the 1080 as much as you can get away with, and then upresed 720 footage for situations where you can't avoid the codec breaking. I never tried mixing footage of different resolutions without downresing to the lowest common denominator. Can you stick some 720 footage in an 1080 video without it being obvious to the average viewer?
 
admactanium , those uploaded pics.. unadjusted enlarged and framed would do just fine in our Tate Modern here in the UK :D
 
Let me try 720 AVCHD. I haven't tried that. I just did a bunch of different quick tests with it and it does change dependent upon the ISO but that effect is present in nearly all the AVCHD stuff. The MJPEG stuff is universally smooth as well. BRB.
