I visited a tv store to check that. I was stunned, standing there in front of a 4k screen and watching a demo over and over again.

Tried to grade A-image as close as it gets (with my eyes and this screen and ACR): http://we.tl/PGDkRov6vb Probably someone better than me could get more out of reds and magentas. Or i think they're lost.

It also applies the noise reduction!

OK, B-image is 3840x2162 didn't want to spoil it for you guys.

This thread is full of misconception )

Yep that's something. A new definition for the motion picture at your home. Though i'd like to know if there's a way to put more bitrate to the blacks and if NX1 is capable to do chromatic aberrations compensation for non-native lenses as well.

Maybe h.265 is very efficient, but there is much more information in blacks in the still jpeg compared to the video jpeg. BTW, Andrew, the difference in pixel count is such a giveaway ) Anyway, a great amusement here )

A looks better, B looks RAW )

Either sensors (full readout) or processing (throughput and compression), modern Sonys just don't have it yet.

Yes indeed, players and transcoders use it.

It may seem brighter even if you have the same amount of light per pixel. For instance, a picture profile can make it look brighter - there's no raw, so the picture is always altered in some way. According to DXO, if you choose ISO800 setting, you get ISO452 and ISO641 for GH4 and 5DMk3 accordingly. (I've added Pentax for the reference). So, GH4 compared to Mk3 should be darker at same ISO settings (if we shoot RAW stills). GH4's actual ISOs are much lower (almost twice) than indicated.

Maybe it's better to transcode until there's a hardware acceleration for h.265. You can drop HEVC directly to Premiere throuth a frameserver like Avisynth Virtual File System, but decoding HEVC 4k takes too much of CPU power, i'd personally keep it for the NLE tasks. Transcoding is the simplest part and for now, it saves time. BTW, in Windows a free tool called MeGUI can be used for transcoding, just made the 100mbps files (+40% in bitrate) out of Andrew's samples.

Andrew, could you share the original h.265 files to play with?

So, the color filter moves horisontally, tripling horisontal resolution. Since the sensor is square in shape, does this mode require an anamorphic lens to avoid interpolation in post?

Well, 16kHz mode suggests a filter which should do an r-b-g thing really-really fast.

I have to agree, touch autofocus is one of the things you get used to almost instantaneously. I think this feature should become mandatory for a consumer photographic product, just like the autofocus did. It is not to be considered a premium feature - hey, you get that in a 100$ smartphone, that's what my consumer mind is telling me.

Yeah, and my old fullhd monitor is actually 6k too if i count the subpixels! ^)

Probably the only way to avoid that is a really fast filter, like 16kHz one. Right, it doesn't make sense. You don't simply capture 6k pixels of horizontal resolution from a 2k sensor.

Lots of people like the higher framerate. They buy new TVs and watch movies with that function enabled, and some even reencode movies multiplying framerate, and we can see those movie versions are quite popular on torrent trackers.

I'm sure modern CPUs could do that for a FullHD@30fps in realtime in a special environment. Anyway, architecture makes huge difference. A 10Wt image processor is able to outperform a 100Wt CPU of PC architecture when it comes to certain tasks.

Transcoding is the minor problem, that's the point of view from a former owner of this manufacturer's camera. There are so many things about cameras that can be done wrong. Let this topic not end up with a "Nice try, Samsung!"

That's why they use those small boxes, don't they?

Hmmm, i'd prefer to see green leaves and red buttons in one shot

Would be great, a real-world test is the answer anyway.
