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

I'm having aliasing issues in my original footage. =T Dunno what it's from, trying to figure it out.

I've seen people have problems with 5D, EX1 etc. etc. with aliasing. Take a careful look at how codec, display system, output, preview etc. is dealing with pulldown, aspect ratio etc. especially if scaling or pulldown removal is involved.

I have a mondo FTP server would be happy to look at any footage - I'm on Vegas and AE CS3.

Exactly, banding in the sky as well. But hopefully Isaac is right that the bad compression of YT is the main reason for that fault.

IF thats what y'all are talking about by "Banding" its totally just compressor artifacts, and since YouTube is not giving us 17Mbps, its certainly the result of YouTube and the other online streaming formats. You can't take %90 of the data out of an image and look at it and then think that the original image wasn't degraded.

The flickering, is interesting, its like those particular frames are exposed at a higher iso than the immediately preceding and following frames. But the image quality doesn't change-- dunno if its youtube, the camera or something in between.

I still can't judge whether that flicker is in the original footage. Youtube does nasty things to footage.

I agree.

On the other hand: Compressing to YT & Vimeo seems to add some blur which smoothes-over some of the weaknesses in the GH1's video (well, actually all video).

That's why I'm interested in seeing some GH1 video shot with a (very) light diffusion filter on the lens ... e.g.: possibly trading off a little high-freq. resolution in return for fewer video compression artifacts.
 
Kholi, Hunter, Phil & other GH1 users: Have you come to any conclusion as to whether or not the GH1's 720p30 MJPEG mode looks better/worse (in terms of compression artifacts) compared to the 1080p24 AVCHD mode?

e.g.: If it's more pleasant-looking, 720p30 MJPEG might be preferable to 1080p24 AVCHD.

Resolution-chauvinism aside, which flavor of HD does the GH1 seem to record the "cleanest"?

(I wonder if Panasonic's "women in the tropics" GH1 sample videos were shot at 720p30 MJPEG?)

Hey Kholi,

I'm an editor. I'm curious to know how you ingested your footage that you are getting aliasing. Also - what your timeline settings are and do you get this aliasing in all programs you open the file in.
 
It's in the RAW and after the Inverse.

Dealing with ProRes for conversion. Do you think it might be an issue with ProRes? I really need to get Premiere. Final Cut is old hat.
 
Care to put up a still of the worst image? Quick question - did you bring the file straight into compressor or simply do an export to compressor from a final cut timeline. Export to compressor causes some headaches. If you did export to compressor it may be a field order issue with the timeline before you exported.

I would love to see a still. Or is there a way you could send me a short raw clip. I would love to work on it for you.

Working from home today. Doing a batch export with plenty of time to spare.
 
English Firmware Update for Japanese Camera?

English Firmware Update for Japanese Camera?

For all of the early owners that have purchased the Japanese Version I'm curious if you think that a firmware update will add an English menu system? Is that the hope?
 
Well, I don't know. The footage looks like it's missing something. Maybe it's just the way its shot or the subject matter but it just feels like video somehow, even if it's just a little bit.

After hearing about the pulldown, my hopes for the GH1 dropped significantly. Granted, if it's the only game in town for a small unsuspecting manual controlled 1080p 24p VDSLR, then I'll have no choice but to go with it. The Leica M thing was a good snare but the camera has to work for me above all else before I plunk any money towards it. Otherwise I can sit and wait for a Scarlet.
 
this thread is torture. Please- I just need to be put out of my misery. I keep coming here over and over looking and hoping to see evidence one way or the other. Hope or no hope? Please just put something out there for all to see. its got me strung out on dvxuser. anyone that has footage right out of the camera take pity on us. i know others must feel this way. do we need to start a petition for footage.:happy:

I doubt Nikon will develop a sensor with optimized readout for video as the GH1 for the D400. Nikon may be waking up to the possibilities and manual control but they've got little to no video codec, so it may well be just a little more control, 1080p MJPEG and not much more.

Unless Canon and Nikon can really move on a dime, it could take 12-18 months before we see a video centric model from them.

Plus, I'm really starting to like the 4/3 format. I've never liked big cameras even in the film days and I'm hoping that this is just the first body in a series of 4/3 video bodies. So I'm leaning to selling my K10d and HV30 and making the 4/3 committment, even if this is not 100% perfect.

Could be - I just made a Blu-ray of an HV20 ProRes short and even though he swore it was 23.976 progressive, the 24p blu-ray MPEG looked crappy with aliasing and blur.

I would not get too excited yet. I was the 6th person in the US to get a DVX100 and no software had support yet. The first footage I shot with it had "issues" that turned out all to be codec and pulldown related.
