    Here is a rather nifty new video on YouTube shot
    with the Panasonic GH4 at 4K and streamed at a *FAR*
    lower data-rate than the original on YouTube - and
    even so, it still looks very good (view it at "1080p",
    at 100%):
    It will be interesting to see if it is better (for a
    1080p end product) to shoot at 4K 3840x2160-24/30p and
    down-scale the result to 1080 after editing, or to
    shoot 1920x1080-60p All-I 200Mbps original. I suspect
    that some of us would prefer the latter, but at least
    both options are available...;-) The GH4 can also
    shoot Cinema-4K (1:1.85) 4096x2160-24p (no resolution
    down-sampling is necessary when doing this), and there
    is the possibility (using an accessory connector-unit
    and external HDMI recorder, and with some processing
    of the video) to have 10-bit 4:4:4 1080-24p output
    from this camera(!). My interest currently is in the
    shooting of 1080-60p video at 200Mbps All-I to a
    U3 SD card in-camera (to keep things small and "cheap",
    and these cards are becoming available at 32-gigs for
    under $100), with the end result being 1080-60p at a
    high data-rate for archiving the edited video (although
    there is currently no distribution format available
    for this, alas...;-).

    Another 4k video test I found on YouTube for the Panasonic GH4 camera is
    the Takehito Miyatake in Kyushu. I don't have the web address as the
    program I viewed the video on does not display the youtube address but if
    you type into YouTube
    'DMC-GH4 Sample Video door Takehito Miyatake in Kyushu' then you'll find
    it. A very attractive scenic video that includes a rainbow in the mist.

  3. WOW!!! Thanks!
    It's at - and
    as usual (unless you have a 4K display...;-), select "1080p"
    for the resolution, and watch it at 1920x1080 on your monitor
    for best sharpness (which is excellent!). It does take a few
    seconds after starting to switch resolutions to 1080p. Some
    GREAT scenery here, including a great long tele shot of the
    top of a volcano - beginning just before it erupts(!!!)!
    NIFTY!

  4. We were able to download the original files yesterday,
    and last night I tried working with them in Vegas. I
    was able to get them into Vegas by changing the .MP4
    to .AVC (2K for this one, 4K for the "birds" one),
    but I was unable to export modified video (Pro 11,
    and maybe it is time to install the latest version of
    Pro 12...;-). I was able to considerably improve the
    distant tele view of the volcano erupting, and captured
    some frame-grabs of that from Vegas, but could not export
    the video - so far...

    Maybe there is some copyright protection preventing you from exporting the
    video.
