Panasonic GH4 4096×2160 vs Alexa 2048×1152 24P
Cinematographer Sittipong Kongtong compared the performance of the $1,700 GH4 vs the $40,000 Arri Alexa. The GH4 footage looks a bit under exposed and cannot match the Arris dynamic range. Videofilmaker.com analyzed the results and writes:
Despite this (lower DR), the GH4 definitely holds its weight compared to the Alexa. For the most part it looks smooth with little to no motion blur when pausing. Although, the jagged movements on those reflectors being swung around (in the first vid) really screams DSLR; something you’ll need to consider if your film calls for action scenes. The results show that in daylight the GH4 is absolutely worth the price tag and a bit of a godsend for indie filmmakers. Whether or not it does as well in low light conditions will be another matter entirely.

This comparison is a “bs”, if the guy wanted to compare the cameras he should have used Cine D and -5,-5,-5,-5,-5 on GH4 to get the flattest profile similar to Alexa.
100% my tought!
fukwits galore
Cinelike D isn’t a LOG setting like Alexa/Blackmagic have. The style that he shot is actually about as flat as can be.
Actually you are quite wrong! if you searched on the internet for other Gh4 samples you cold find really flat samples, as described Cine D and -5,-5,-5,-5,-5 to all settings. It may not be called LOG but GH4 can be set extremely flat, comparable to Alexa LOG: http://vimeo.com/89232617
That’s not flat at all. Look at the saturated blues in the water and sky. Unless they’ve changed something in the firmware I can guarantee you it’s not like Alexa/BM LOG.
It’s basically the same Cinelike that they used in the AF100
Panasonic GH4 will have Cinelike-D & Cinelike-V
These are professional color profiles for maximum dynamic range in high contrast shots. This footage posted has been graded, please inform yourself of these profiles before you spread wrong information. Panasonic GH4 will have this flatter based profile…..
My mistake, I was in a hurry the link. The original film is to big to be posted, but here I grabbed some shots from it. The author sad it was filmed in Cine D style with all settings dialed to -5,-5,-5,-5,-5:

Panasonic’s biggest problem will be keeping up with demand =)
Fanboy Supreme.
Does the GH4 interpolate the rows or does it pick up some and skip the rest?
It throws away the lines. The Sony RX10, instead, interpolates…
load of wank
wank to Alexa or the other one? : )
Poor customers.
A 4K Crap dressed in DSLR clothing.
Ah, because proper 4K has to reflect off a mirror?…
Actually you are a Troll dressed like an user LOL.
Panasonic GH4 rooks and your trolling sucks!
I’m wondering roughly how much a Micro HDMI external recorder for 4K 10bit 4:2:2 is likely to cost (when it is finally invented…)?
I am only still shooter …so sorry for stupid Q. …but does this video prove that the alexa is better ?
If yes ..can you tell me what I should focus on to see the alexa is better ?
cause what I see that the alexa is some kind of grey …while gh4 has saturated colours ..the rest looks to me similar quality
I am not an expert but look at window details upper left corner area. In general higher DR means more details in the darker areas. I think the GH4 was not shot flat enough to expose for these darker areas, so it may be that the GH4 can hold its own in this scene. Filmakers like flat capture to get as much details as possible, and then “color grade” later. Also the details of the swinging reflectors which personally for my uses is no big deal.
This shows us, that people can not match a picture and are not
able to be only 0,1% near something cinematique.
But for the sales of the masses ( and so called iditos-slave-on-demand)
it is fine…. and the shwo goes on.
next year we see..
