Introducing 4K

Discussion in 'Amateur Video Production' started by Gary Eickmeier, Apr 24, 2013.

  1. And now, ladies and gentlemen, for your viewing pleasure, a 55 inch TV for
    $5000. Step right up, don't be shy, you sir - have you ever seen 4K for
    yourself? You won't be sorry. And if you act fast, a free DVD of.... well,
    OK, sorry about that, but soon we will have all kinds of stuff to play on it
    and you will be ready!

  2. 8^), 8^), 8^)!

    But, "seriously" now - JVC brought us an early 2K HD camera, only
    in low light it was too obvious that it used two sensors to make
    up the resolution, side-by-side. NOW, however, with 4K JVC brings
    us a camcorder with *four* sensors (I think...;-)! So now we can
    enjoy producing content for our $5K screens with a cross in the
    picture instead of merely a vertical line! WOW! 8^) Hey, in a
    while we may have 4K broadcast material that also produces little
    "boxes" during fast motion to further entertain us - but these
    may be smaller, yet more numerous on the screen, so they would be
    even more entertaining!;-) Can't wait, sharpness nut that I am!;-)

    I feel there is a stage where any improvements in the resolution of the
    picture will not be noticed by the human eye.
    There would be an advantage of being able to make photos of the video
    frames at a higher quality if 4K video is recorded
    The biggest improvement was AVCHD for video cameras and LCD TV's.
    One problem with higher quality photography is in finding space to store
    the result. 1TB drives can fill up fast.

    And now, ladies and gentlemen, for your viewing pleasure, a 55 inch
    Increased resolution matters more as screen sizes increase.

    For example, 1920x1080 video on a 32" TV is roughly 69 DPI (1920 divided by
    27.9" width).

    That same 1920x1080 video on a 70" TV is only 31 DPI (1920 divided by 61"
    width).

    Compare that to most printed material that is at least 150 DPI, with "photo
    quality" usually being around 300 DPI. In other words, a 1920x1080 image on
    a 70" TV is only one tenth of a photo quality print.

    Even with 4K video, you would only get about 67 DPI on a 70" TV (4096
    divided by 61"). That's still less than half of what is traditionally used
    for printed images. There's still plenty of room for improvement.

    That said, there are many people who can't see the difference between SD
    (720x480) and HD (1920x1080) video now.

  5. Look about 11 min 07 sec into this program...

    http://revision3.com/tekzilla/bowers-and-wilkins-z2-review

    It's a $1500 4K by Seiki (or at least that was the price when the
    program was made).

    Here's the company:

    I never heard of them before I watched the show.

  6. I hadn't looked at the Seiki site before. When I did, I had trouble
    finding the TV in question, so here's a direct link:

    Also, it's still $1500 at TigerDirect:

    And even cheaper at Amazon:

    Five stars - from exactly one reviewer :)

    Thanks for the chart. It would be useful for anyone buying a TV to know if
    its going to fit in a certain space and if they are able to put it in the
    car to take it home. Good to know that the largest size TV will fit past
    the door frame (grin).
