Julian Posted April 20, 2014 Share Posted April 20, 2014 I've been playing with the GH4 for a while now. I'll share my video's here. Shot a lot more material, still have to edit/upload it. Will do so in the following days. Go over to Vimeo/YouTube for all the details in the lenses/profiles/settings used. You can download 4K files or high bitrate on Vimeo. Cinema 4K mode - sunset and lowlight. The 14mm makes razorsharp 4K images. Also used a cheap 200mm f/3.5 Vivitar lens. Hard to get the focus exactly right and maybe not really suitable for 4K. For the video on Vimeo I used pretty high iso values. Shots with the birds are 3200 for example. 96 fps slomo test: with shallow dof shots it is pretty sharp. I have some slomo sufing shots as well, the resolution looks less good with very detailed scenes. Short test shot at ISO6400 in C4K. Anamorphic test with Minolta MD 28mm f/2.8 and Petit Cinevision 1.5x MiL0, jurgen, nahua and 6 others 9 Link to comment Share on other sites More sharing options...
MiL0 Posted April 20, 2014 Share Posted April 20, 2014 slow motion video looks great - thanks for sharing :) Julian, nahua and Ari 3 Link to comment Share on other sites More sharing options...
dahlfors Posted April 21, 2014 Share Posted April 21, 2014 Beautiful shots, Julian! The iso 6400 shot seems surprisingly good for such a small sensor. Your footage really makes me wish that the GH4 tech will trickle down to GX7-like models sooner rather than later, so I can convince myself to upgrade from the Sony NEX :) Julian 1 Link to comment Share on other sites More sharing options...

Julian Posted April 21, 2014 Author Share Posted April 21, 2014 The battery is excellent by the way. Shot 179 4K clips today (10-20 seconds) between 11:30 - 15:00, camera was on pretty much all of the time. Still 2/3 full.

AaronChicago Posted April 21, 2014 Share Posted April 21, 2014 That was one of my main reasons to always pick up the GH3 for a long handheld shoot. The battery life is insane. A full day on a half battery. Julian and nahua 2 Link to comment Share on other sites More sharing options...
Julian Posted April 21, 2014 Author Share Posted April 21, 2014 Rolling shutter test. I would never shoot something like this (I'd do it with a wide angle) but the RS doesn't look bad at all to me. Link to comment Share on other sites More sharing options...
Julian Posted April 21, 2014 Author Share Posted April 21, 2014 Shot some people today!

MattH Posted April 21, 2014 Share Posted April 21, 2014 Thanks for posting all of these tests. The flexibility of the GH4 seems to be pulling it far ahead of the competition. One thing I would like to see is the affect of picture style adjustments. Specifically, lowering the highlights on cinelike D and V but keeping the shadows at default. The affects of the saturation and sharpness settings would be interesting too. Link to comment Share on other sites More sharing options...
dahlfors Posted April 21, 2014 Share Posted April 21, 2014 Hah. I immediately recognized the song. I also found that song on soundcloud a year or so ago, favourited it and thought "This would be a lovely song for a video" :) Julian 1 Link to comment Share on other sites More sharing options...
MaxAperture Films Posted April 21, 2014 Share Posted April 21, 2014 Great job with the tests, Julian. That rolling shutter skew seems very minimal given the speed of travel, was it shot in 4K or FHD? Julian 1 Link to comment Share on other sites More sharing options...

I get everything from the Vimeo Music Store (Creative Commons, Attribution only). Always end up with the same artists... Always a pita to pick some music. I know half of the tracks there by heart by now :unsure: Link to comment Share on other sites More sharing options...
nahua Posted April 22, 2014 Share Posted April 22, 2014 Very nice detail. Just can't believe how clean the image looks. Especially like the 2nd video (YT) with the wind farm/docs in the background. Just amazing detail and colors! I can't wait for this camera! Thank you for all the tests! Julian 1 Link to comment Share on other sites More sharing options...
Gerbert Floor Posted April 22, 2014 Share Posted April 22, 2014 Nice, my favo dutch surfspot :). I liked the slomo shots on the beach. How did you get the camera, is it already up for purchase? Julian 1 Link to comment Share on other sites More sharing options...
Julian Posted April 22, 2014 Author Share Posted April 22, 2014 It's a test sample from Panasonic Nederland. Testing it for www.digifotopro.nl. Early may it'll hit the shelves. Link to comment Share on other sites More sharing options...
AaronChicago Posted April 22, 2014 Share Posted April 22, 2014 I got mine yesterday. The one thing that is very pleasing and unexpected is the motion cadence. I love the way Blackmagic cadence looks, and GH3 was a little choppy. From what I've noticed so far with the GH4 it's more along the lines of Blackmagic cadence.

Julian Posted April 22, 2014 Author Share Posted April 22, 2014 Do you still have the GH3? Would like to see a comparison of both regarding motion cadence. It's something I haven't been able to put my finger on, so curious if the difference would be obvious to me. Congrats on receiving the camera! I'm sure you'll enjoy it.

AaronChicago Posted April 22, 2014 Share Posted April 22, 2014 I just sold my GH3 :wacko: It could be placebo effect, but to the naked eye it seems like a more pleasing motion. Link to comment Share on other sites More sharing options...
nahua Posted April 24, 2014 Share Posted April 24, 2014 I know with my GH3 I have to find that balance of 60P codec with the right shutter speed. I usually use 1/160-1/250 depending on how much motion. I didn't see anything wrong with Julian's footage though. I think it's just something you have experiment with to get the right amount of motion blur or cadence. Link to comment Share on other sites More sharing options...
Nikkor Posted April 24, 2014 Share Posted April 24, 2014 I just sold my GH3 :wacko: It could be placebo effect, but to the naked eye it seems like a more pleasing motion. It's something that has been bothering me a lot with my nikons (on a steadycam it becomes very visible) and which doesn't seem to happen in raw cameras, I might be a little bit obsessive but it's something important to me. I wish someone with tecnical knowledge could explain what exactly creates this, or if it's just in my imagination (or yours). I'll check some gh4 footage.
