Interesting new video camera...

Discussion in 'Amateur Video Production' started by David Ruether, Feb 4, 2014.

  1. A VERY interesting new "video" camera is about to be
    announced, the Panasonic GH4k(? - for name...;-), early
    Friday morning in London, with specs possibly available
    in US sometime Thursday night (due to time difference).
    According to what appears to be reliable information
    provided at it will have H.264 4:2:2
    color all-intra (not GOP) recording at 100Mbps, switchable
    4K and 1080p (the latter at up to 120fps), an attachable
    XLR-mic accessory, improved high-resolution OLED rear
    and eyelevel VFs, clean HDMI output for monitoring and
    external recording, and improved heat-dissipation for
    extended video recording. It appears that it will be
    essentially an upgraded GH3, with the wide range of
    excellent MFT lenses fitting it (see my reviews of some: ) plus the
    usual cheap adaptability to it of just about any other
    lens available, extensive Panasonic controls (over just
    about everything on or in the camera...;-), small size,
    light-weight, weather-sealing, and excellent video
    image-quality (in common with the Panasonic GX7, G5, G6,
    and GH3, the image sharpness of which generally surpasses
    that of ALL the other available hybrid still/video cameras).
    Likely under $2,000 for the body alone, and for recording
    at the highest qualities, a special very high speed SD
    "P2" card will be needed (that Panasonic also will be
    offering). 'Spensive, but it's a fraction of the price
    of several of the alternatives that aren't as good...;-)
    Gotta sell even more gear soon so I can afford it...! 8^)

    Sounds good David.
    The only problem is if your recording at the highest quality then you need
    a video editor and a equipment that can playback the higher quality
    recording. My Canon camera can record video at 91 Mbps using All-I video
    compression but to get a smooth playback I would need to put it on Blu-ray
    disc as its more suited to playing back a higher quality video.

    Sometimes recording technology races ahead but equipment to play the
    advanced technology is lagging behind.

  3. I think both Vegas Pro 11 and 12 may be able to handle
    4K video (they accept images up to 4096x4096, as I recall,
    and are fairly uncritical of frame-rates), but my main
    interest is shooting in highest-quality, then down-sampling
    (NOT in real-time, for better quality...) to 1920x1080-60p.
    Then the problem is: how do I present that for viewing?
    The recent video I recommended here,
    shows an ASTOUNDING amount of fine detail in motion (for ANY
    presentation method, let alone with Internet streaming!), and
    it gave me a good hint of one approach. I had NOT been a fan
    of 24p video, due to its "choppy" rendering of motion (when
    viewed on a computer, anyway...), and to its reduced visual
    resolution (due to diminished data rate, due to the reduced
    frame-rate) - although most movies on disk are 24p and look
    fine for both detail and motion smoothness. In the process
    of getting that video onto disk for viewing on our HD TV,
    we discovered that it was streamed in MP4 at a "slow" data
    rate of about 6.6Mbps(!!!). I had been having problems getting
    onto disk a video consisting mostly of stills (which the above
    video also is...), even at 40Mbps on Blu-ray. This video went
    as-is as an AVCHD DVD!!!), and it looked GREAT (and with the
    same detail-level as the original, but with smoother motion!
    Obviously 24p works very well when played back using a good
    Blu-ray player and viewed on a TV. Panasonic has also stated
    (even though it is not in the Blu-ray spec) that 50Mbps
    1080-60p AVCHD CAN be written to Blu-ray, and be successfully
    played back using some recent Blu-ray players - BUT, I have
    never heard of anyone successfully doing it, and so far, I
    have also not been able to do it (but I have an idea yet to
    check out...;-). Anyway, 24p may be the key to getting high
    detail-level material onto disk *when the result is played
    on an HDTV*, as shown by this SPECTACULAR video shot in
    Wyoming and then streamed... Wish me luck in my quest! 8^)

    One problem I noticed with this camera was that at the 4K shooting option
    it does not do 25 fps so it seemed to be aimed at parts of the world that
    use 29 fps. I am wondering if it offers PAL in the 4k format or just NTSC
    (or maybe 4K type format replaces PAL and NTSC as a type of recording

    I have a feeling that this is a very expensive camera that mainly
    professionals would buy.

  6. From the specs (see my post above this thread), it appears
    to be suitable as-is for both PAL and NTSC areas, and needing
    only a reboot to convert it from one area to the other. It
    is predicted to be "under $2,000" in the US, placing it as
    expensive, but cheaper than even high-quality Mini-DV SD
    camcorders used to be, and FAR cheaper than top-end Nikon,
    Canon, etc. still cameras are now (ones with FAR inferior
    video-shooting capabilities), so it is also kind of a
    "bargain", given its capabilities...;-) Several Panasonic
    MFT bodies already surpassed the video image-quality of
    the dSLRs, and this one offers much more than even those
    did for video-shooting.
