    wow..these framegrabs of 1080 vs scaled 4k to 1080 really make their point !

    Tried my TV but it's quite an old Bravia flat screen which reports the gh4 as being 'out of range'..

    My NLE (avid) isn't doing a very good job of the downconvert from 4k to 1080p - lots of aliasing. So tried the 200mbs 1080p on someone wearing glasses -always a tough aliasing test - and was very pleasantly surprised! So I'm looking to get a ninja or similar, and wondered if there was any definitive word on what frame rate the camera actually outputs via hdmi before taking the plunge, as some report a 50p output instead of a 25p output when working in pal. Anybody with a way of testing this?

    For anyone interested in the performance of the GH4 for wildlife/birds, here's Part 1 of my review:

    http://iwishicouldfly.com/iwishicouldfly/journal/html/051614.html

    In this article, I primarily focus on cropping/panning inside of 4k video and I discuss the merits of using frame-grabs for prints.

    BTW, thank you for this website. I don't post often, but read much and have been using the GH series of cameras since the GH2 and this website was instrumental in getting me going with modifying the GH2.

    the compression of Vimeo is very bad :-( password: julz

    Just noticed that when the camera goes to sleep and wake up you loose all the settings you adjusted for the last shot on the camera, SS, Aperture, WB, ISO etc... Not sure if that is only on C modes which I mostly use but its annoying as hell. It should be able to remember them unless you turn off the camera completely.

    @ MikeLinn - At 3:03 in, the texture in the balconies at screen upper right is exquisite. We are so accustomed to experiencing a barrier between viewer and motion picture that we don't even know it's there, until we see something like this. The cinematographer and the GH4 in this film lift that barrier.

    @oscillian and @FilmingArt thanks!

    Big mistake on my part with the red ball. We came up with the concept on the spot and filmed the bad bowling first. When we shot the intro last, i could have sworn we used the blue ball, but nope!

    @aaronchicago

    Looks Good and concept was funny..... What I really want to know though is HOW did that Blue bowling Ball turn RED.............

    @v10tdi Zebras stay on when adjusting ISO if you use the touch screen 'tab' menu to adjust. Not perfect but may be of use to someone.

  • oscillianoscillian

    @aaronchicago Great timing!

    I know it conserves battery to put Live view mode in 30fps (setup menu, page 2/6), but I'm finding easier to focus (especially punch-in focus) with Live view mode set to 60fps. Anyone else notice a difference? 30fps mode seem a bit grainy and soft. Could just be me.

    @mrbill

    Anybody REALLY annoyed how zebras disappear when you adjust iso speed?

    zebras, exposure and everything else. Yes, annoying.

  • aaronchicagoaaronchicago

    Shot this with 1080 modes and the Panasonic 12-35.

  • mrbillmrbill

    Appears to be no practical difference between 16-235 and zero-255 luminance recordings when importing into avid (which maps everything to 16-235 anyway). In zero-255 you do get to use 100% zebras though, as opposed to only 95% zebras in 16-235. Anybody REALLY annoyed how zebras disappear when you adjust iso speed?

    Richmond, VA Brief walk-around in 4K:

    Standard picture mode used. Lumix 12-35mm and 45-175mm lenses. Edited in Sony Vegas Pro 13.

  • caveportcaveport

    Also had success feeding line level external audio into the mic input. One must be very careful with levels but works well. No audio issues with noise or other artefacts. Did a 2hr plus recording test for an upcoming corporate event shoot. HD 1080 25P at 50mbs looked great and the battery was still on 3 full bars! This is a beast of a camera!

  • caveportcaveport

    For those that use colour bars, be aware that when recording them internally, the recorded levels are only correct with video levels set to 16-235 in the camera setup section.

    @andrew00 this is another reason why the GH4 must be used properly, not in super extra mega hipper flat mode. LOL

  • markr041markr041

    The GH4 is also a 108060p video camera (50Mbps MP4):

    All the pedantry, pageantry and monotony of a commencement shot colorfully and in HD.

    You can download the original 1080p video, which was not re-compressed.

    Standard picture mode used. Lumix 12-35mm and 45-175mm lenses.

    One thing that's a frustration for me is the focus peaking. I love focus peaking, I'm glad to have it. However when you start dialling down the contrast settings it becomes s lot harder to see, or rather the peaking doesn't show up. Considering how good this is on the bmpcc, it's a shame it's weak on the gh4 (as it was on the g6)

    Philip Bloom has begun writing a presently evolving review of the GH4. He had quite a few positive things to say:
