- Jordan, are you allowed to share with us some of your ungraded, unedited, un-YouTubed footage for us to have a look/play with?
looking forward to when you have a play with an external recorder and see that that brings from the v-log

I'm not a stills shooter so i wouldn't want more pixels. Less pixels for better sensitivity actually sounds great, but i don't think they're gonna decrease pixels. They seem hell bent on making an 8k camera but i wouldn't want that, although vfr in 4k would be sick. Only improvements i really want are better sensitivity and dr, 5 axis sensor stabilization, even better codecs to allow internal 10 bit, better color science in not just the log but all picture profiles. Although i'm sure they'll throw in some crazy feature to try to get everyone to upgrade.

Unfortunately, I've agreed with Panasonic not to share any ungraded V-Log L footage. You'll have to deal with YouTube'd footage in the interim.
In terms of 4K, you get better color reproduction by improving the oversampling. If you do it in 2.2 MPX increments - 11, 13.2, 15.6, 17.8, etc. - you get more RGB information and negate the effect of the Bayer filter. Off tests, GH4 resolves ~ 1500-1550 lines due to having only the 8.8 MPX sensor for "right on the dot" 4K. A 22-24 MPX sensor would then avail a higher quality 4K, after using a crop for 16x9. With their variable aspect ratios that are suitable for anamorphic, Panasonic will have to find some sort of a balance among these various ratios and pixel counts for video.
That was way too processor intensive for even stills. There have been and are some stacked designs in the works, apparently, but it seems like oversampling does the trick (although, it's also processor intensive).
FWIW, Panasonic has made a statement that they want to go 8K before the 2020 Tokyo Olympics, thereby introducing 8K cameras by 2018. With no price points given, I will just assume that GH5 will be out by 2016 - will give it a two-year cycle before 8K is shepherded into the main stream - and should be an oversampled 4K (or 5/6K).

After seeing the V-log GH4 footage, I think the GH5 is going to be quite the camera. At this point in time I am more inclined to wait than purchase a GH4 if the V-log sees the light of day soon.

Why does seeing the GH4 V-log footage have any bearing on how good the GH5 is?
Maybe thinking that the GH5 will be announced very soon?
Isn't NHK committed to providing Olympic coverage in 8K by the time the games happen? And who's studio/ENG cameras are they going with to make this happen?
But none of that has to do with the GH4 or v-log. I do wonder if there is a way to make the encoder provide 10 bit 4K to the current GH4, 10 bit and log would certainly add a lot to this "aging" camera. then if they could fix the delay issues on HDMI and SDI. All of this should (needs to) be addressed before the GH5 sees the light of day. That said, I keep hoping Fuji will make a killer stills/cinema camera, the X-T1 is tantalizingly close.

The push to 8K has a lot to do with the imminent omnipresence of VR I believe. That's 8K at 90fps(realtime) BTW. Those of us who remain "traditional" filmmakers will be a different breed entirely (because most of the language of cinema will go out the window with VR too) and may be happy to "settle" for 4K. I imagine the law of diminishing returns means that 8K will have even more resistance than 4K is being met with (i.e. even less-noticeable jump in picture quality than HD to 4K).
My guess is H265 will allow the focus to become more about colour depth so GH5 could feasibly be 10-bit 4K?

Ikegami had one at this NAB but NHK has experimented with other designs before and are aiming to provide a live 8K broadcast from several MLB games (no doubt, featuring some Japanese players) and even the 2016 Superbowl in 8K. (I posted a few more links in the "Cameras in the 21st century..." thread recently)
From the DVXUser user consensus, the 10-bit internal is hardware dependent and this may have to wait until GH-5.
From the natural progression path, GH5 should have 10-bit, H265, 60-72 fps in 4K, 14-stop DR, 5-Axis stabilization, etc. When you think about the jump in technology A7R MI presents from a year ago and calculate where this is headed a year from now ... well, one may not need anything more than GH5 for anything but the feature films.

About the GH5 - From my point of view, I have never been a fan of the look of the GH4. Seeing the V-log footage has impressed me and I would now think of buying a GH4 if this update was released. But then I stop and think the GH4 is probably past halfway in its development life. I see the V-log development as native to the next generation GH5 which will probably have better specs and sensitivity than the GH4. This space is moving quite rapidly and buying right now should be on a need only basis as every six months something better will be coming out. I am looking for a longer term purchase and I am guessing the GH5 could be that camera.
But at the price of the GH4 I might be over-thinking and buying and selling would not be that big of an issue. Bu it all hinges on the V-log for me.

That's an old Sony sensor (Sony still owns 10% of Olympus).
