Panasonic S1 V-LOG -- New image quality king of the hill
Evan Fotis Georgoulakis replied to Andrew Reid's topic in Cameras
Hi Andrew, you mentioned that the S1's long GOP is equal to ALL- I. can you do a curly hair chroma-key test between All-I (GH5) / Long GOP from S1 and a take with p4K BRAW? it would be very interesting to see the results. Cheers -

A quick question: In 6K 4:3 mode, using normal lens (non anamorphic) will the GH5 produce normal (1:1) aspect ratio, usable image or a squeezed one? I am asking, because if it can produce a 4:3 video image like SD cameras did-but at 6K resolution- it would theoretically be ideal for shooting video in portrait mode, for better green screen keying results, instead of the current 16:9 landscape shooting which throws away more than half of the captured image left and right due to the relatively short vertical size.

EOSHD Pro Color for Panasonic (GH4, GX85, G85 + more)
Evan Fotis Georgoulakis replied to Andrew Reid's topic in Cameras
So does this LUT work properly only when footage has been shot in Standard mode?(i wonder who uses that mode fwiw) With GH4 footage will it work -properly-with cine-D, or tweaked portrait profiles? -
Andrew, I very much agree with your second point about seamless design and functionality, the wifi functionality, is hideously implemented and mostly unusable as is today, even with mirorless makers, sony etc. But i think the fourth point is the real issue and game changer. Even people who remember the optical viewfinder era, find it much easier and natural , to see the results of changing settings imediately before their eyes. In everything we opt for simpler more efficient and WISIWUG designs, and once EVFs evolve a bit more in speed and quality, they will totally render OVFs obsolete, along with the whole design structure built to support them.

Image A ...deceptively sharper and with warmer white balance, plus no clor fringing which usually happens with in camera jpegs and VIDEO, yet lower color bit especially obvious when zoomed way in, has horizondal color bands and non uniform noise around detailed areas (barcodes etc). Image B ...deceptively clinical cool white WB, chromatic aberration all over, what lens is this?, and seemingly less sharp. When zoomed all they way has better/ more uniform noise structure, and less banding indicative of a RAW capture. At first sight Image A has the advantage, but with proper grading/Raw processing Image B will produce superior results.

On the D750 some specs from the manual do not seem that hot: Bitrates for 60p is 42Mbps max, and 24Mbps for 30p. That is less than half of what the old 5DMkII used to record at around 40-45Mbps for 25fps without any ML installed. I wonder how Andrew finds it better than the MKIII. Also, time limit for 60p@42Mbps is just 10 minutes .

Power Aperture - Auto Iris This is one video oriented feature I havent read any comments about, either from this site and forum or other video centric ones. Nikon USA site states: "use Power Aperture control for smooth iris transitions and Auto ISO for smooth exposure transitions". This is in addition and separate from:"Manually control ISO, shutter speed and aperture while recording". http://www.nikonusa.com/en/Nikon-Products/Product/dslr-cameras/D750.html?cid=web-0914-dslr-hp When posted a question about the actual functionality of "auto iris" What exactly does auto iris do? Does it allow smooth change of aperture while recording video, like when using cine or declicked lenses? this is the answer I received: Yes, aperture will change automatically as the light changes. Have you discovered anything new concerning this functionality? Is this allowing auto ISO in Manual mode, where one sets aperture and shutter speed, so exposure remains constant by automatically changing ISO lik DPreview mentions or is aperture changed smoothly internally and if so how?

Nikon D800 hacked with 50Mbit/s high bitrate video option
Evan Fotis Georgoulakis replied to Andrew Reid's topic in Cameras
Its a pity that the D800, so accomplished as a stills camera, is so lacking in video. The live view is notoriously noisy in low light situations that render it almost useless. In a project with black bg with white silouettes that tneeded critical focus - manual that is, even with the super sharp AF 85mm f1.8G)- live view zoomed in, was not fun to look at with all that noise. I ended hooking up an external 24" monitor for better control. Two online examples that illustrate this: http://www.ronmartblog.com/2012/05/fail-nikon-d800-live-view-vs-canon-5d.html
