    I think we can move on from random AFC comments/tests. What is more interesting is "I really wanted such and such shot for this scene and here is what happened". I did 20 minutes of blog style and it was terrific for that. 
    Have noted the Vlog assist dropping. Am investigating. 
    Really happy with the ease that it edits. Very tempting to use it a lot despite the size.

    JazzBox reacted to Amazeballs in Manual focusing on fly-by-wire MFT lenses   
    I just bought a used Pana 25 1.4 and besides its stunning imagery, I was very surprised by its manual focus capabilities, which was unexpected to me. This lens was produced back in 2011, but its the best manual focus fly-by-wire native MFT lens that I've used so far and by a great margin. I own 14-140 zoom (3.5-5.6), 42.5 1.7 and 20 1.7. They all are PITA for manual focusing, especially 42.5 1.7 which I would consider otherwise a superb small and affordable lens, but its MF is just so wired - one second very slow, then suddenly blazing fast. Completely unreliable for video and I hate its unpredictable acceleration and speed. Who's genius idea was to setup modern MFT lens behaviour like that? The 25 1.4 has fast smooth MF with close to none acceleration so I can easily pull focus on any shot without any extra effort or shaking my camera. Its reliable and constant. But all other lenses I've tried are plain terrible at that!
    So I wounder, WHY PANASONIC MAKE THEIR CURRENT LENSES BEHAVE THIS WAY?!  
    And it would be so EASY to correct, just by adding some extra menu setting with a profile for every lens for a) acceleration control (starting from zero) and the lens speed itself. Only two freaking parameters and thats all. That would safe so many people from constant struggle with that MF flybywire bullshit. 
    And now try to explain my why its not done yet? And consider that Panasonic stronghold is video, they are perceived by many as video camera makers, they excel in video.. but, they did not offer any solution in that department for all this years. Unexplainable idiocy. 
    BTW, maybe some hero hacker can modify MFT lenses firmware to change those parameters? That would solve this too. 
    P.S. Well at least now I have one lens with which I can focus comfortably.

    Excited to test the image quality out of it.
    I don't think it will compete with a larger sensor like the GH5 that's optimized for still and video with V-log, but I mean, for a director on a shoot who wants to steal a shot of the sunset on the scout, and doesn't have a camera on their person, just a quick shot here and there.
    For instance I did a short film with Matty Brown - and he added a bunch of picks up because he has a beautiful hyper-connectic style.  
    Say he didn't have a small mirrorless or DSLR on him, and there was like a scene with tons of birds flying in the air, and the DP was changing glass or whatever, and he just whips it out of his pocket, it may be okay in the piece, since it is 23.98, maybe a good shutter speed, HEVC codec - it may cut.
    It's exciting to me to think this.
    There have been so many missed moments on sets because the crew is wrapped for time reasons that the director would love to grab.

    First apologies to starting this thread - I know there is another one - but that seems to focus on the iphone x as a phone.  This is about using it and h.265 to record.  And possibly log or raw out of it.
     
    H.265 is no joke - as I have seen with the NX1, and with apple supporting it, you can bet your donuts they will make it easy to integrate and convert.
    And a wide angle and  a  telephoto lens, with an optical zoom. 
    This could be a useful camera in the field if you need to pick up a shot.

    HDR codec and HDR10 display will make a difference. Is the H.265 10bit?
    4K 60fps on a phone proves heat can be managed in such a thin device, and that Canon with their shitty DSLRs have no excuses remaining.

    Apple however are generally more boring than they used to be and lack charisma under Tim Cook. The products are still solid, but there's something missing. Personality?

    JazzBox reacted to Andrew Reid in Canon 5D Mark III - 3.5K and 4K raw video with Magic Lantern   
    You're not quite understanding the way the hardware works Jimmy.
    The sensor delivers that 3840 pixel wide image under the normal Canon firmware, every time you hit the focus magnification button and it's capable of sensor windowing with any full pixel readout crop of the full frame sensor, like 3.5K, 3.3K, 2K, whatever you like. Magic Lantern are extracting the existing capability of the camera within the normal spec and clock speeds of the hardware, they are not running it at full capacity or increasing clock speeds.
    That 3.5K image goes into the buffer as normal and then Magic Lantern take it from there and put it onto the card. The only heat increases come from a harder working card and battery due to the data rates. The processor and sensor do not get 'worked at breakneck speed'. In fact the processor is relaxing if anything because it doesn't need to think about compression or H.264.
    The only reason the live-view isn't as nice as in the normal 1080p mode, is that Canon's code is designed to show the 5x punched in display for focus checking, so Magic Lantern had to hack it to give us accurate framing for the entire resolution, which is very difficult as they lack any kind of documentation from Canon or an SDK to tailor camera operation to their choosing.
    The hardware is 100% capable of 4K video and likely with the same MJPEG codec as the 5D Mk IV and 1D C. The reason it is not in there is due to marketing. They wanted to reserve the feature for the 1D C and target the 5D3 predominantly at a stills audience and consumer crowd for whom 4K would be somewhat overkill or wasted and result in more support costs, distracted focus in the marketing messages, confusion on the shop floor, etc. The 5D3 also wasn't allowed to compete against any of the pro Cinema EOS cameras which were fresh on the market at the time it was released, because the margins would be much greater on these cameras and video shooters should not have been tempted by something cheaper offering such a recording high spec... That's another reason the 1D C cost $15,000 on release.
    Plenty of compact flash cards in 2012 were fast enough for MJPEG 4K, otherwise they wouldn't have released the 1D C the same year doing MJPEG 4K to compact flash cards. You talk like the cards didn't even exist or would drop frames.
    Also in 3.5K there are no dropped frames or occasional messed up frames, it is continuous recording with perfect image quality, like you see in my video. Sometimes a clip may stop due to the data rate being on the limit of the card, but there are no corrupt frames...and we always did have these occasional stoppages with the original uncompressed 14bit 1080p as well... that didn't stop a ton of AMAZING work being shot with it. For many things, shorter takes are enough. And if you want longer ones just decrease the resolution slightly and shoot 10bit lossless instead of 12bit.
    10bit has more advantages than just less banding my friend
    In rec.709 your dynamic range is limited in 8bit because you simply run out of room.
    We know the look that comes with trying to compress more dynamic range into a rec.709 8bit, colour suffers, it looks like HDR puke.
    That's because with 0-255 you have regions of large variation in brightness crammed into the last 5 or 10 shades, so things like a sky looks like crap, no accurate colours in it.
    LOG is a way around this to a certain extent but is also a form of compression
    The reason the rec.709 image looks so good on the GH5 is the entire image processing pipeline is 10bit this time round... things have room to breathe and when you do bring up the blacks or pull down the highlights there's 100x more information in there and they don't fall apart.
    So in short, 10bit = more dynamic range, especially on a 10bit HDR display using Hybrid Log Gamma.
    That's why the HDR standards all demand 10bit or more. Dynamic range!
    Also 10bit raw = more dynamic range, plus more control over colour and white balance as it isn't baked in.
    Also lossless compression = 50% smaller file sizes with no loss of visual quality, so it is almost like having uncompressed raw, rather than compressed H.264 10bit.
    In addition the bump to 12bit and 14bit on the 5D3 with Magic Lantern gets you a bit more dynamic range, but close to the ceiling of the sensor.
    I'd say the image quality at 10bit is very close to 14bit... 12bit even closer as to makes barely any difference. 14bit has a bit more accuracy in the highlights. Shadows still look AMAZING in 10bit, like the Blackmagic raw cinema cameras but less noisy.

    There's a lot of misinformation out there because there's a lot of fake 10bit.
    The whole camera, colour processing, colour profiles, image pipeline and codec need to be built around 10bit for it to be an advantage, like on the GH5, or in raw on the 5D Mark III with Magic Lantern (where the colour profiles and image processing is done in POST, bypassing the camera's 8bit processing limitations).
    The 10bit GH5 Rec.709 image is night and day better than the GH4 10bit HDMI output.
    And don't get me started on 8bit "uncompressed" HDMI... It is compressed as hell! No point in recording it. Especially not as 10bit ProRes.
