    The 4K 10 bit files that GH5 records internally cannot be read by some software such as Resolve. Also, the files are in an inter-frame codec so editing crawls to a halt in some software.

    The solution is to transcode from H.264 10 bit to an intraframe codec like Prores. Here is an ffmpeg command line that does that:

    ffmpeg -i "input.mp4" -c:v prores_ks -profile:v 2 -qscale:v 11 -vendor ap10 -pix_fmt yuv422p10le "output.mov"
    But you have to be very careful to use an ffmpeg version that was compiled for 10 bit support.

    I've liked clear zoom too on my Sony cameras, but the 1.4 extender function on the GH5 is 100% lossless. It's really like having an optically perfect tele-extender.

    Olympus cameras have the same noise. Its the IBIS. The sensor assembly is kept in position mainly with electromagnets that don't operate when the camera is off. The design by Sony uses strong magnets which stabilize the sensor even when the camera is off and there is no noise.

    And the GH5 does not give you a professional FF still camera in the package
    does not have superb canon AF in video 
    does not have canon lenses (speed booster with no proper AF, thanks but no)
     
    I am angry at Canon because of their approach to Indy filmmaking wasting a big potential they had. But let's appreciate this update if real. The least it can do is shake Nikon and Sony a bit to bring us better video features soon. 
    A 5DIV with CLog, 1.3 crop, 3K at 60fps and nice codec would be a good thing.

    10bit vs 8bit, is there any noticeable difference?, yes, but only for the expert eye, and give a little more room to push in post, so it is really not a break dealer, and guess what, you have the chance to get RAW from ML in the future....mmmm!!!!
    focus peaking.....I don`t care, i am a filmmaker, all i need is DPAF from Canon.....
    let`s see the price...GH5 = $2,000 , but you also need metabones = $700 , total $2,700
    Canon 5dmkiv, BHphoto = $3,400, but I saw it for $2,700 on ebay since last week from a store in NYC, and guess what?, yeap, it just sold out minutes after the announcement of crop factor reduction....
    I will chose this 5dmkiv over GH5 any day of the week, and I am sure many GH5 preorders will not be sleeping well tonight....

    The main advances I see from this camera are the 1080p out of camera being of comparable sharpness to downscaled UHD, the ability to use stabilization with my manual primes, and usable V-Log files and monitoring without an external recorder.
    The low light imprpvement and removal of the sensor crop for 4K are just bonuses.

    He's genuinely excited about the value of these Lumix cameras. Just as he is excited about Metabones Speedboosters, Contax Zeiss lenses and other lenses such as the Nikon 'Bourne' zooms or low contrast Tokina RMC optics. Instead of just being openly excited about these things, he had the chance to get involved in some degree. Doesn't mean he sold his soul to the highest bidder and agreed to bring us the Lumix gospel regardless of what it stands for. He's still advocating the same genuine opinion and recommendations he's already had before, so nothing has effectively changed except for perhaps a little influence in pointing the company further in the right direction? I friggin' respect the guy, he's great, skilled and knowledgeable!

    Regarding the V-LOG Key... when upgrading the GH4 to the GH5, you do need a new one, right? Or is it 1x per model type?
    Does anyone know if there will be a kit with new 12-35mm f/2.8 II zoom? I expected so, but, haven't seen it listed anywhere, also no like DMC-GH5A product designator for it?

    this camera is a game changer , I was shown the prototype GH5 last June in a meeting with Panasonic and the spec was amazing , ( I have had to keep very quite since then) the GH5 is everything we have all wanted in a Pansonic Camera , now its finally coming out its going to revolutionise Indy Film making like no other camera has . I expect to see this on alot of Indy movies over the next few years , it will be my main camera for movies now.

    Ehh, what Sony forgets to mention in the headline grabbing campaign is that the card is still V30 meaning the minimum sequential write speed can easily drop to 30MB/s. Even the upcoming GH5 400Mbps firmware will need V60 at least and that's far from raw. At the moment only Delkin makes V90 cards, offering a 90MB/s minimum speed.

    Jn- reacted to joema in New information regarding H.265 on the Panasonic GH5   
    Software support is obviously required and this often lags hardware by years. E.g, Intel's Quick Sync hardware-assisted H264 encoder was introduced with Sandy Bridge in 2011. To my knowledge Premiere Pro only recently started supporting that -- and for Windows only, not Mac. That was roughly a six-year gap.
    Skylake's Quick Sync has HEVC/H265 support for 8-bits per color channel but Kaby Lake will be required for HEVC at 10-bits per color channel. Hopefully it won't take Adobe six more years to add support for that.
    I think nVidia's NVENC has HEVC hardware support starting with Pascal and AMD's VCE with Polaris, but the software development kits, APIs and drivers must be available and stable for application developers to use. So there is a difference between raw hardware availability (in silicon) vs being able to harness that from the application layer, which can require stable and tested SDK and driver support. 
    Traditionally there has been concern over image quality of hardware-assisted encoding, but FCPX has used Quick Sync for for years (single pass only) and it looks OK to me. But I don't think it has H265 hardware support yet.
    Lots of people want H265 because the file sizes are smaller, but you don't get something for nothing. H265 requires vastly greater computational complexity which means the CPU burden to encode/decode is much greater. In this paper, VP9 was 2,000x slower to encode than x264, and H265 was 3x slower than VP9 (or 6,000x slower than x264). So it took thousands of times more computation to save at most about 50% in size. This is just a single paper and algorithms and efficiencies are improving but it illustrates the basic principle.
    iphome.hhi.de/marpe/.../Comp_LD_HEVC_VP9_X264_SPIE_2014-preprint.pdf
    If that computation is done in hardware (IOW you essentially get it for free) then it may be a worthwhile penalty. But if only software encode/decode is used for H265, it may be impractically slow. Also if full and high quality software support at the SDK level is not available, the fancy silicon doesn't help much.
    For the iPhone it is affordable for Apple to use H265 for Facetime. They completely control both hardware and software, and quantities of scale mean any design or fabrication cost is amortized over 50 million phones per year. If it costs a little more to add H265 logic to a corner of a SoC (System on a Chip) that already has 3 billion transistors, it's no problem.
    For a software developer like Adobe, they must deal with three basic H265 hardware acceleration schemes, NVENC, VCE and Quick Sync, some of which have multiple versions, each having varying capability and features. So maybe that explains the delay on Quick Sync in Premiere Pro.
    H265/HEVC has also been hampered for years by disputes over royalties and intellectual property, which is one reason Google is pushing VP9 which has roughly similar capability but is open source and royalty free. However VP9 itself will probably be replaced by the similar but improved royalty-free AV1: http://www.streamingmedia.com/Articles/Editorial/What-Is-.../What-is-AV1-111497.aspx

    "The new 12-35mm F2.8 II ASPH. POWER O.I.S. and 35-100mm F2.8 II POWER O.I.S. now have a black finish. They also have new iris mechanisms that are supposed to give smoother aperture transitions when shooting video. One bit of good news for owners of the existing versions of the 12-35 and 35-100 is that those lenses will get a firmware update at some point to make them work with the Dual I.S. 2 system."

    When compared to FF video (16x9 cut of a 24X36mm sensor), the GH5 with the XL booster would be a 1.33x crop, and with the Ultra booster it'd be 1.47x.
    Remember that the XL is less uniform in sharpness across the frame- it is a little sharper than the Ultra in the middle, but softer outside of that. The Ultra is more consistent.
    Also remember that with the sensor moving due to IBIS, you end up effectively using a larger image circle than without IBIS. So even if IBIS only moves the sensor a mm in each direction,  your 13x19mm sensor now needs an image circle that can cover 15x21mm.
    So APS-C lenses with small image circles, like the Sigma 18-35mm f1.8, which barely cover the sensor with the XL booster, may now go soft or dark in the corners as IBIS shifts the sensor. Or worse yet, you may have the actual edge of the image circle show up as black corners.
    This is why I think it's safer to go with the Ultra booster for the GH5.

    And thats the problem right now for many people. If you are an Adobe or a Resolve user you are getting half the performance for double the price compared to a $1500 XPS 15. For example:

    Also, by reducing the battery capacity a macbook pro now doesn't give you any better battery performance anymore . Under load it even gets worse...

    For that money you are better off getting an XPS 15  AND building a hackintosh (if you want FCPX) that performs even better than the Mac Pro:

    Here is an interesting take:
    https://www.bloomberg.com/news/articles/2016-12-20/how-apple-alienated-mac-loyalists
    I know the mac accounts for 10% of the sales and the "pros" account in the best case 10% of that, but Apple really needs to focus on the "pro" side of the mac once again cause alienating  %80 of the NLE users (without even counting resolve users) is not going to bring more sales.

    So we can't trust DPReview anymore to give honest feedback on camera's, so what, now that we know we don't have to visit their site anymore. In fact, who can you actually trust on the internet, I recall reading an article on this site about the Canon xc10, a camera I was planning to buy, and Andrew trashing it but then later on when he actually had the camera completely changed his mind, it went from "the camera has a IQ that's a bit better then a gopro to it reminds me of a Super 16 version of the C300 Mark II", Eventhough this is not the same as what DPReview has done it has the same effect on me as a reader, to me writing a heavily opinionated article will misinform your readers in exactly the same way as writing a article that is sponsored by the manufacturer.
    I personally like to read Gordon Laings articles on cameralabs as he conducts his tests for every camera in the exact same way and he just leaves it up to his readers to form an opinion and I like to watch the Camera Store TV guys videos just because they are entertaining as well, Philip Bloom falls in that same category. I actually value the actual users opinions most as they will report problems with a camera after months of use, they will give you information most reviewers won't be able to because they use the camera just once for the review before returning it to whoever lend it to them. And even then you need to be careful as sometimes reported problems are user error.
    If you want to buy a camera it's best to wait a few months after it has been released, read up as much as possible you can about it so you can separate fact from fiction and make a more informed decision.
