    Why they are still using baseline 66 in an mp4 container is more to the point.

    Because no one cares. :-)

  • driftwooddriftwood

    @mpgxsvcd They certainly can. That wasn't really my point. Why they are still using baseline 66 in an mp4 container is more to the point.

  • mpgxsvcdmpgxsvcd

    @driftwood

    I thought they co created the standard with Sony. Can't they do what ever they want with it and call it AVC-HD?

    I think the bottom line is that the G5 still retains the AVC-HD file structure that some people dislike if you want to record true 60p footage.

  • driftwooddriftwood

    @mpgxsvcd Panasonic bastardise the AVCHD standard with a lot of their own code. Besides a lot of the mp4 container stuff theyre doing in current Lumix cameras are baseline 66 AVC/AVCHD Lite creations.

  • KihlianKihlian

    @VK OK I think I missed something. Have you a good link about MP4?

  • mpgxsvcdmpgxsvcd

    @Vitaliy_Kiselev

    Are you sure about that? I thought they shoot in AVC-HD or in the MP4 container? It seems to indicate that the true 60 FPS modes are only available with the AVC-HD framework. However, the 120 FPS mode is only available with the MP4 container.

    @Kihlian

    Nope.

    All new cameras shoot in MP4 container that can be incompatible with AVCHD standards :-)

    And MJPEG. No more amongst the available modes.

  • KihlianKihlian

    For sure GH3 has avchd 2.0 specifications, reported below. Also 4:2:2 if, only on Motion jpeg.

    The Photokina 2012 is a good idea. Maybe we see somebody from this board in Cologne at the Panasonic-stand.

    back to topic: I dont believe the GH3 will have an sensor with global shutter. I think they use a sensor like the G5. Well 1080p with 60 frames sounds good, also the better resolution in the displays. 120FPS at 720p would be perfect!

    4:2:2 - sounds good too, but I dont think this camera will have that feature. I hope they will have a higher and lower ISO setting and last but definitely not least: its hackable like the GH2!

    @mpgxsvcd You right, but a mechanical shutter is faster and better than a electronic (except a global shutter) Take a photo with the GH2 in Highspeed (40 PFS) from a rotating prop, you will see the rolling shutter effect. But the effect is gone if you use a mechanical Shutter - thats the different and I think thats a good feature that gives you the opportunity to take high quality shots without the rolling-shutter-effect-bullshit . OK, you can make just 50k - 80k Photos with this shutter, but I think its ok, because you can switch to the electronic shutter for snapshots.

  • mpgxsvcdmpgxsvcd

    It looks like the 120 FPS and 240 FPS modes are "High Speed" video modes just like the GH2 has. Except for the GH2 shoots the slow motion at only 30 FPS.

  • mpgxsvcdmpgxsvcd

    @Dazza

    No they just increase the read speed of the sensor from 60 FPS(G3) to 120 FPS(GH2 and G5). It is likely that the GH2 will read out at 250 FPS like the Nikon 1 series camera that doesn't have a mechanical shutter at all.

    They are still susceptible to the effects of rolling shutter. However, you really have to try to ruin the shot to actually ruin the shot if they read out at 250 FPS or faster.

  • DazzaDazza

    could full electronic shutter mean global shutter?

  • mintcheeriosmintcheerios

    I really hope so. I have an intervalometer for the GH2 and didn't use it much in fear that I'd destroy my shutter if I used it too much. If they have a full electronic shutter, I wonder if they'll implement an in camera intervalometer.

  • Vitaliy_KiselevVitaliy_Kiselev

    Also full electronic shutter for time lapsers will be present, as in G5.

  • DazzaDazza

    @mpgxsvcd 1080p60 is a given, the G5 has it. As is increased LCD resolution to 920K, bring it to the same level as Sony and Nikon cameras. I hope they really do mean total control via smartphone, it would be great to be able to remote the camera. A RGBW sensor would be great, though they would have to give us 14bit RAWs to get the most out of it

  • mpgxsvcdmpgxsvcd

    I would be willing to bet the GH3 has 1080p @ 60 FPS and 720p @ 120 FPS. Just a hunch though. :)

  • disneytoydisneytoy

    I'm a fan of Panasonic Engineers. They have done amazing things so far. They have had a good amount of time on the GH-3. That is why I was happy the GH-3 wasn't introduced back with the Nikon D800/Canon 300/5DMIII/1DX. I'm sure we will have:

    Better processor Better DR 1080p 60 Wifi

    I hope:

    Flat grading profile No higher megapixel. enough is enough Tethering for video and stills (wired or wireless) Fly by wire focus (wifi or wired) A video HDR mode like Red and Canon's Magic Lantern

  • bwhitzbwhitz

    • 4:2:2 mpeg 2k at 24/25/30fps (maybe 48fps possibly?)

    • AVCHD 2.0 up 60fps

    • clean HDMI out (internal codecs are so 2010 anyways) :)

    • maybe .5-1 stops better DR?

    • custom color-profile support

    • some surprise burst mode... like 6-8 seconds of 120fps in 1080p?

    That's about all I really want/need, anything else would just be icing...

  • christianhubbardchristianhubbard

    operation by smartphone sounds pretty awesome. not sure i like the cloud synch or wifi transfer to Tv, as I'd rather just use hdmi.

  • Vitaliy_KiselevVitaliy_Kiselev

    Some things that GH3 will be able to do via Wi-Fi:

    @zigizigi Your #1 is most likely confirmed on the GH3 if the "leaked" specs on the G5 are anything to go by: http://www.43rumors.com/ft5-no-joke-full-g5-press-release-leaked-in-oman/

    This information is rated as an FT5 meaning that it's an 81-99% chance the rumor is correct/

  • christianhubbardchristianhubbard

    Has anyone heard anything of an RGBW sensor in the gh3? Apparently it would revolutionize the dynamic range by giving a dedicated channel to preserving highlights. Thoughts?

  • zigizigizigizigi

    A couple of wishes.

    1. AE/AF Lock to work during video recording, not pre-record only.
    2. Ability to switch rec-start/stop behaviour to movie button only. This is to prevent accidental rec stop if you press the shutter button too hard while refocusing.

    • 1080p60
    • Better color noise processing
    • Better Auto WB
    • More fine-tuned curve & tone for each film mode
    • Usable ISO to 6400
    • Better DR
    • 2.39:1 aspect ratio
    • EVF eyecup redesign so that 3rd party eyecup can be attached easily

    I'm expecting just gradual upgrades that will satisfy most of us if the body price goes down enough. I will be happy if it makes much improved photos.

  • driftwooddriftwood

    If it makes an appearance at Cologne's Photokina 2012 in September (according to strong rumours) and the current Panasonic brochure shows availability of GH2 is checked till October, then the GH3 is more than likely to appear on the shelves between October end and December 2012.
