GH4 4K Panasonic video camera, official topic

    Sorry if this has been posted already, but this thread is... a wee bit long.

    Just upgraded from GH2 to GH4, and I have a question about the codec Panasonic is now using. Specifically, I'm curious about 4K/100Mbps and FHD/100Mbps codecs and rendering settings in Premiere Pro CC. With the GH2, I found that matching rendering settings to the source material was the best way to produce smooth output that didn't look like stop-motion. I'm trying to do the same with the GH4, but I'm seeing conflicting things.

    When choosing "match input, high bitrate" as the rendering setting, Premiere chooses Main profile, level 5.1. But everything I've read online suggests that the GH4 uses High profile, 5.1. Anyone know which it is, Main or High? Also, what is the distance between keyframes in both 4K/100Mbps and FHD/100Mbps?

    Or does anyone know of a simple tool for analyzing footage to determine codec specs?

    Thanks ahead.

    Shot with V-LOG and different lenses (Oly 12, Oly 45, Samyang 7.5, Canon 24-105)

    Noise is visible in most of the shots and also banding. For me it is ok, even tough I personally get better pictures with Cine D in this changing light situations

    The V-log update is now available for customers in Spain . I made a small tutorial in Spanish of the installation process .

    The price just rose from $879 to $999 at the ebay site noted above by Mike Linn:

    They sold 261 before the price rise.

    Damn, and I just bought the G7. Oh well. Need to learn the G7 first anyways, maybe by then, GH5 will come along.

  • jjj_ri_usajjj_ri_usa

    Wow. $879 for a GH4. Very tempting! I'm still using my old GH3 and saving $$ for an eventual GH5. But...I've rented the GH4 before and I know what I'm missing. 4k as source material allows such great flexibility in delivering stabilized and even zoomed, crisp 1080p! I've been tempted by the G7 before, but now, $879 for a GH4! Wow.

    I've never seen a GH4 this low priced. I doubt it will ever be so low until after the GH5 is released, which...probably won't be out tilll, when? Late 2016?

    These are selling fast on this e-bay site. 236 sold already. Seems like a fantastic bargain.

    Does anyone have any speculation if the GH4 will ever sell for less? This price is so tempting!!!

    @Vitaliy_Kiselev super cool man, thanks... i guess hardware might be the problem too then..pity, gotta get a blackmagic assist..

  • Vitaliy_KiselevVitaliy_Kiselev

    @fomalhaut3

    LSI - Large-scale integration chip.

    You can look at many at http://www.personal-view.com/talks/discussion/429/cameras-and-lenses-cut-in-half#Item_92

  • fomalhaut3fomalhaut3

    thanks @Vitaliy_Kiselev for the quick reply, sorry for asking, what s LSI? do you think it will be possible to do so with a firmware update or it's a limitation of the hardware?

  • Vitaliy_KiselevVitaliy_Kiselev

    what does prevent the gh4 to record 10bit 422 on sd card?

    LSI design prevents it, and firmware.

  • fomalhaut3fomalhaut3

    what does prevent the gh4 to record 10bit 422 on sd card? New sandisk SD cards are Rated at a Max. Read Speed: 280 MB/s and Max. Write Speed: 250 MB/s That should be enough for uncompressed 10bit right? are we gonna see this possible in a new firmware update? blackmagic video assist records 10bit 422 1080p 60fps on sd right?
