Test footage from the pre-release Panasonic GH3 at Photokina

That looks pretty damn good to me. In a controlled environment, shooting fiction, I'm sure the results could be truly impressive.

Beautiful films have been made with 5D2/7D cameras, this is a step up in so many aspects, it's about time we stop waiting for the perfect camera and just get on with filmmaking.

Well. Andrew. I made some screen grabs. I wish you'd clarify the big variances in the Juggler's skin tones. Was that due to different angles/lighting or did you grade clips differently?

I'm keeping my fingers crossed that Panasonic is still listening and can fix the moire and aliasing by November. That said it clearly seems not as bad as the Canons, and there is so much more that this camera does right, top of class especially for the price. I'm pretty well sold on the test footage I've seen so far. At the moment it just looks like my GH2 will stay on hand at all times as a b-cam to for wide shots.

Interesting, I hadn't noticed how green that shot was from Genius. Reminds me of my room which has subtle green pigment in the cream paint and lit with fluro gives it that green pastey look. Auto WB or custom WB should fix that so I put it down to a creative decision.

The juggler green look is something else. A light over head not matching the WB?

Not saying its wrong be surprised if it was camera error.

Interestingly, the yellow skin tones are from AVCHD mode I think, and the better skin tones are ALL-I. 90% sure I have that right, will have to check and confirm later, it might be the other way round.

For reference this is the levels problem I am still having with the GH2 after all these years, and now GH3. Why does my Mac not recognise that GH2 footage should be 16-235 not 0-255?

Quicktime treats it as 0-255 as well, crushed blacks and blown highlights.

maybe this can explain some moire/aliasing problems ... [url="http://www.photozone.de/m43/766_pana1235f28?start=1"]http://www.photozone...1235f28?start=1[/url] @12mm 5.78% distortion ... thats bad ... most gh3 videos with aliasing/moire problems we're done with that lens ... French market test , photokina etc ... that lens @12mm is almost fisheye and camera need to do extreme distortion correction ...
Lumix 12-35mm F2.8 is not that good lens...
too much camera tricks to look good ...
@Andrew
gh3 records 0-255 or 16-235 ?

I think GH3 is going to be a huge let down. The skin tones and colors in that footage is really ugly and fake looking to me. Theres the canon DSLR ugly pink tone in skins. I think im going to buy another GH2 before they become hard to find.

Panasonic is smart. GH2 was a huge accident. Why would they make the GH3 actually better when GH2 killed their af100. I think they're saving the good stuff for their next proper video camera. Maybe af200 or something who knows.

They've just given this camera some fancy stuff like higher frame rates to sweeten the deal.

Has to be either the ambient light or a similar white balance issue.

I just read a post on m43 rumors that reminded me a significant amount of chromatic aberration is actually corrected in-cam on the 12-35 lens (and other Lumix lenses).

Now I wonder if this could be the image processing bug that is giving a moire-like appearance in some of the GH3 footage in higher contrast areas (stripes, etc). It could help explain why there is no color moire effect visible, rather just the funky dancing pixels in areas of high contrast. Simply bringing the lens down a stop or two could possibly be the workaround that confirms it is in fact the root cause as that should eliminate the need for CA correction to be invoked in the software. It might be something to try under controlled conditions if anyone gets a chance to do an in depth hands-on review.

Wouldn't that greenish tint on the juggler be a green spike from the overhead flourescent perhaps?
I doubt the lighting was 100% color-correct.
That means it will probably favor either green or magenta.. the top looked green, the lower looked magenta.

Maybe it was color-correct lighting and this is still an anomaly.

Curious.

From this grab, it seems it is just your monitor that is clipping. Non-calibrated Apple screens are really bad, they are too contrasty, a crush the black by a big margin. Not speaking of being glossy glass.

On my calibrated Nec LCD2490WUXi, the left image is correct. No black crushed and - as there is any - no highlight clipped.

You should really look to calibrate your screen, or get a better one.

Man people are really going overboard with this stuff. I can't see why we only want to focus on the images that look bad and ignore the ones where things look GREAT! How do we keep the camera in that sweat zone is what we need to be asking. What was the cause of the bad color casts and what were the conditions that lead to the great skin tones on other footage? I think this camera is gonna be great once we learn how to get the best out of it. I'm not seeing consistently bad image, just some freaky stuff that could be caused by any number of combination of factors. Could be lens correction, bad lights, settings needing tweaks, firmware issues...
