Panning 'mud', reasons why and firmware update

PappasArts said:
I'm wondering about playing back already recorded footage from the SD card in the GH1 Via HDMI to a HDMI capture card device assuming that the GH1 reconstructs the playback output in proper 3:2 pull down in a 1080i signal vs SW programs that seem not to able to perform reconstruction well. People have reported on output of footage played back from their PS3's as having correct pull down etc...

That's an interesting thought and well worth looking into for sure.

Well it's post codec at that point. Whatever damage has been done to the image due to the poor or insufficient implementation of the 17mbps AVCHD is written in stone at that point.

So it's 1080, or 720 or whatever you've recorded at. But if you've recorded mud it's there now.

(I'm assuming the live HDMI out was brought up in the hopes one might be able to record externally before compression - sorry if I'm not following what's being asked here.)

Jack, if your saying it outputs UNTIL you hit record, this sounds like a hack
might be possible. I know nothing about electronics. but the blackmagic
intensity card for my HV20 is only $ 250.oo bucks. { not sure if the cs4
drivers are working yet, its been delayed and I havent tested lately}

However, then maybe EVEN A CARD could somehow coax a signal out of it?

Who knows people at blackmagic or AJA or?

My camera doesn't come until tomorrow (hopefully) but that's nearly a quote from Kholi I believe. I'll try to confirm miñana. I'm 99% sure he said he had an image until he hit record. Don't think it was just playback ... hmmm ... not sure now.

It's been established that the playback from the camera itself also has the artifacts. Many of the original shots of the "mud" in this thread were photos of the playback screen.

bro, I think any playback would be from the signal recorded TO THE CARD via
codec.

were talking about BYPASSING the recording in the camera.
 
Yeah now we are. He was responding to PappasArts idea that it might output the pulldown correctly from the card though. It's gone back and forth from one idea to the other a couple of times actually.

oh ok - lol.

I don't have a playstation, so have no idea what pappasarts broached.

[ I should change that to "suggested" . Broached, in print, sounds like someone threw up their breakfast }

I have been thinking about this for a week or so. I posted a question a few days ago, however this thread moves lightening fast, so it got overlooked.

If it's possible to capture footage like this, you could grab it from the SD cards via the GH1 in proper form and to a very good codec via hardware codec on card with all 24 untangled out of the 1080i/60.

Since the GH1 has to be compliant with consumer devices on playback from SD card it would output the 3:2 pulldown corrected via the HDMI to a TV etc. This signal would be most likely a 1080i/60 with the 3:2 in correct form. The blackmagic intensity card knows that pattern and can untangle that to a selected high quality codec of choice in true 24fps or 23.98. Just a hypothesis, however could be a good work around if it has merit. Just like capturing video from a HV20.

That said, the PS3 if it has HDMI, could be used as a playback deck to feed a Black magic card too. Assuming the above hypothesis has possibilities....

Thats an awesome idea and theoretically that should work without a problem. Does the intensity do 23.98 input, I thought it only did 59.94? The matrox MXO2 and MXO2 mini should work fine though. I have an MXO2 and will definitely be trying this the moment amazon sends me my damn camera.

The GH1 like other consumer products output it's ( like the hv20 etc ) 24fps in a 1080i/60 envelope. The blackmagic card takes that 1080i/60 from camera playback and strips that 24fps out of the 1080i 3:2, then out to the desired codec and preferences you want. Just like you would capture video from the HV20.

The PS3 can output 1080p/24hz, though I'm not sure it will from files on a card. It defintely will from a bluray.
 
Side note: Some clean looking GH1 1080/24

You see, just like I wanted to see. The pan in the first one is not a whip jerk pan. It follows the subject firmly and smoothly. To me is like kind of making the camera float and flow. You are not tearing the image by sudden movement. I am sure crane shots and tracking shots will look good as well when well executed.
It would be good to know all the camera settings used. I just had a thought before seeing this videos that the I.Exposure setting might have to do with the mud as it tries to expose properly front and back causing the image to break in the process. Who knows. Something to look into when I get the cam. Thanks for the links.
 
First experiences with the gh1 from a german user. Sorry, only the bad google-translation. Despite that, maybe you can understand the most:

Edit: A small review:

In this sentence: "He versoßt fine structures

MPEG -Brei, MPEG-mash, but only in very specific frequencies, so that the very fine structures remain." "versoßt" means "intermeshed" and "Brei" is "mud"​

What is new?

Not a lot it seems...

Of course the GH1 is capable of good footage, and bad footage.

Posting good footage doesn't prove very much.

As far as I'm concerned, the workaround is to avoid whip pans in FHD mode and use MJPEG instead until Panasonic release a firmware update.
 
That sounds like a fair compromise. This problem can be avoided, nobody is helpless.

It may be a good idea to create a guide or something with a summery of what has been discovered in the past 82 pages. How to anticipate the problem, and how to avoid it.
 
Dear god! This horse is a zombie horse! It just keeps coming alive! Alive! Run!

Oh and I believe a summery has been twice that I know of in this thread.

I say if you are going to do some crazy whip pans then throw on some dramatic motion blur in post and make it interesting. Turn a negative into a postitive is all I'm saying.

Well, it should, because it shows that there is a way to shoot and avoid the problem. It means that when everything is in order the camera has no problems. It should mean that there must be proper steps and settings to follow that will avoid the problem. And knowing how to set the camera for proper capturing is exactly what we need to find out. If somebody is getting it right it means that everybody else is getting it wrong, correct?
 
Hello Friends,

This and other threads/footage related to GH1 is pretty informative to know what this camera is capable of(720/50P). I was looking forward to RED Scarlet as my first real camera until I spotted the release of GH1. All I have to say is that MUD or no MUD, JELLO or no JELLO, this is the camera that is totally capable of shooting full length feature once the camera person understands it's limitations and features to use in the controlled atmosphere.

I must say that this camera is for those who are capable of shooting a movie in the controlled environment. Those who are complaining about panning stuff should remember that MJPEG can be used in those panning situations(now please do not complain about the slowdown of audio in that case [when you want to use that footage as 24P or 25P] as you will never use a talking head during the crazy panning scenes).

All I have to say is that I find this camera to be totally capable of shotting a full length movie under controlled circumstances(and you should not forget that all the movies we see are shot under controlled circumstances).

Looking forward to get my hands on it and start shooting my next movie.

Bye.
