    i don't know why you are using autofocus at all. its a computer, even the best autofocus has no clue what you want! if you bought a camera with a professional purpose and only use it in auto mode, then send it back and get a refund. these cameras were meant to be used with the operator in full control and the bmpcc only has auto functions as a bonus feature. you should not rely on it for serious work

    You don't have to. I've used a few systems that could handle h.264. Mine however, and most other machines I've worked from, typically suffer from laggy h.264 playback.
     
    If you're using a Windows based machine, try DNxHD. It's available as an export option in Resolve under Video Format > QuickTime. Then under Codec choose any of the DNxHD profiles.
     
     
    Not to be obnoxious. But the Blackmagic subforum for Davinci Resolve could net you more accurate answers. :) (Though sometimes you get none.)

    Can you replace the RAM? Apple will do it. (Assuming you buy now before the refresh. The 2014 model has its RAM soldered on.)
    Can you add more HDD space? Not internally without voiding the warranty.
    Can you add in a GPU? Nope.
    Can you upgrade to a higher resolution monitor when prices fall bellow 300? You can plug one in.
     
     
    To it's strength, Final Cut Pro is only $300. That is definitely a huge advantage for the Mac. But you don't need to own an iMac to reap that benefit.

    I used to use iResolution, but it makes edges of trees and grass too sharp. It's basically like the Clarity slider in Lightroom.
     
    The other stuff.. I use iDynamic on High usually. It really brings out a lot of range.
    Then +2 shadows, -2 highlights. This is useful when outdoors and you want some more detail in the sky and dark areas. However it can sometimes make skin look a little too flat.

    I'm sorry, it sounded like you were saying you couldn't get an actual 4k sized image after de-bayering, I think I took the part about the "Nyquist 2x sample theory" and "A 4K Bayer sensor can't actually capture 4K- it's some percentage less, perhaps 3.2K-3.8K" a little too literally. I can see now that you were just saying that it's not true trichroic RGB. And you think with 5k to 2k, the de-bayering factor is less important than 2k to 2k.

    andrgl reacted to jcs in Is GH4 worth it if I won't be using 4k?   
    In simple terms, it's possible to get decent reconstruction using statistical analysis (vs. simpler methods such as bilinear interpolation (which is easy to code and is very fast)). If one starts with super high resolution, such as with RED (say 5K) and are targeting 2K, the quality of the debayer step is less important than say 5D3 RAW 2K debayered to 2K (ACR and Resolve do a much better job than the on-camera hardware+firmware: much sharper and more detailed images when debayered in post). Interestingly , RED Epic at 5K debayered (and without any sharpening) looks softer and less detailed than GH4 4K H.264 compressed (100Mbps):

    I find it best to put your imagination in the form of a sensor.  Each pixel of your eye sees either red, green or blue.
     
    Keep this grid in mind for a 20x5 sensor R=Red, G=Green, B=Blue

     If you're out in a field and shoot a landscape with a power-line glinting in the sun, how does the sensor "see" it?  If the line is perfectly horizontal to the sensor and is two pixels high, then each sensel is debayering using the same light.  The 4 sensels get full values for Red, Green and Blue.  They de-bayer them and each comes up with white light.  The power line will look perfect.  These are the pixels that "see" the line
     
    RGRGRGRGRGRGRGRGRGRG
    GBGBGBGBGBGBGBGBGBGBG
      Now let's imagine that the line is only one pixel high.  That means you might have full red, green, red, green, and NO light from the line on green, blue, green blue, etc.  So what happens when you de-bayer each block of 4 pixels?  Naturally, you get a redish tint because the power line didn't register on the blue pixels.
     
    RGRGRGRGRGRGRGRGRGRG
     
     If the line is on the green. blue line of the sensor, you get bluish (because it's missing red).  Keep in mind, the field is green, so the sensor isn't going to figure out the missing red or blue if it doesn't register it.  
     
    These are the sensels the register
     
    GBGBGBGBGBGBGBGBGBGBG
     
    Usually, "lines" fall above and blow sensor pixels.  If you look at any video with these cameras and look as thin lines you will usually see some form of chromatic distortion because, as jcs says, the camera isn't resolving enough detail (color samples).
     
    In general, there are issues with missing color at all stated resolutions for bayer sensors.  It blends in when we don't have sharp edges that fall between a minimum of 3 pixels we need to properly ascertain the color

    Yes about Resolve, and the 290X is sorta? Workstation cards seem to net better results. Plus DualGPU cards and crossfire/sli setups run laps around one card.
     
    Anyway, it's not unusable by any stretch. I leave NR on its own node and disable it, until I need to render the clips. Then it's pretty much real time, even with secondaries on.

    They are different in some cases, but they also have overlap in the context of light in a scene, transparency of film, or sensitivity of a digital sensor.
     
    References:
     
    "Dynamic range, abbreviated DR or DNR,[1] is the ratio between the largest and smallest possible values of a changeable quantity, such as in signals like sound and light. It is measured as a ratio, or as a base-10 (decibel) or base-2 (doublings, bits or stops) logarithmic value."
     
    http://en.wikipedia.org/wiki/Dynamic_range
     
    "In photography, exposure range may refer to any of several types of dynamic range..   The Light sensitivity range of photographic film, paper, or digital camera sensors. The luminosity range of a scene being photographed. The opacity range of developed film images The reflectance range of images on photographic papers."   http://en.wikipedia.org/wiki/Exposure_range  
     
    No but, in the real world, you can measure relative exposure of anything that emits or reflects light, like between a sheet of white paper and direct sunlight (with a spectroradiometer), which is actually quite huge. Captured by a digital camera, which has it's own dynamic range, and recorded into 8 bit (which has a max of 256 luma levels), the sheet of paper and sun would likely read the same value of 255. So your usable stops have been clipped by your maximum bit depth. If recorded or filmed with a wide dynamic range and encoded into a 10bit Log format (for example) the paper could read as "white" but below 685 (white) and the sun could read over 685, or "over white". LDR and HDR files / workflows refer to dynamic range in this other context. See Cineon, DPX, OpenEXR or LDR vs HDR rendering pipelines etc.
     
    Reference:
     
    "Conversion of DPX code values to relative scene luminance relative luminance = 10 ^ ( (dpx code value – white point) * 0.002 * negative gamma ) Commonly, the negative gamma is assumed to be 0.6 (density) and the white point is set to 685. The result is relative luminance where the reference white is placed at 1.0. To convert into a format like 16 bit TIFF the luminance values are multiplied by 4095 leaving a headroom of 4 stops for the highlights."  
    http://www.acvl.org/digital_intermediates/dicompanion/ch03.html
     
     
     
    The dynamic range of the camera doesn't change, but the range or color depth of what you've recorded does, which has a direct impact on how much you can push the footage in post and the level of dynamic range you can effectively use. 
     
    Anyway, I think the post above sums up what I'm saying about bit depth: "8bit log produces banding. This must be for recorders.".

    There are close to one million books published globally, every year.  There are over 40,000 full-length audio releases.  If you want to check each one out it would take your 53 hours per day (weekends included).  Want to watch every movie?  32 hours per day.  In short,  artists produce more content then anyone can keep up with.  Again, that's just listening/watching once to see if you like it. Then there are magazines, TV, art shows, lectures, etc.  All this content has a simple effect on many people--it makes them anxious.  Big companies grow on the back of that anxiety.  They select a few (if even using political methods) which gives people MORE time to enjoy that art, and less time trying to keep up with all the artists vying for their attention.

    "I rose in eighteen months;
    "The hardest nut I had to crack
    "Was Dr. Dundas.
    "I never mentioned a man but with the view
    "Of selling my own works.
    "The tip's a good one, as for literature
    "It gives no man a sinecure.
    "And no one knows, at sight, a masterpiece.
    "And give up verse, my boy,
    "There's nothing in it."
    ...
    Beneath the sagging roof
    The stylist has taken shelter,
    Unpaid, uncelebrated,
    At last from the world's welter
    Nature receives him;
    With a placid and uneducated mistress
    He exercises his talents
    And the soil meets his distress.

    GH4 is as sharp as you want it or as soft as you want it.
     
    It is however, more detailed than 1080p, because it's 4K. This is not hard to figure out is it!?
     

     
    Download the above 1080p file Michael and take a look at the resolution from both cameras.
     
    5D3 actually has a little bit more aliasing on high contrast edges.
     
    Sharpness between the two is identical. The GH4 does not look 'over-sharpened' and those sloping edges are actually softer on the GH4 (top) to 5D3 (bottom, more jagged).
     

     
    Facts are facts.
     
    Personally I find a use for both. Prefer 5D3 for raw 1080p, GH4 for 4K video. Not better. They're different.
     
    A7S I am very much looking forward to, for low light.
     
    Each has a use!
