    Speaking of cropping. The Z8 has a massive crop to 4K UHD for 120P NRAW. No pixel binning, no "subsampling," no line skipping. But, a 2.3X crop.
    This was shot in 12bit N-RAW HIGH, ZLog cropped 4K 120P to see what we get:
    There is audio too; it is not an S&Q mode.

    Amendment to the above:
    120P 4K is NOT an S&Q setting. It is a normal option for XAVC HS, along with 60P and 24P. Thus, audio is recorded.
    There are two bitrate options: 200 Mbps and 280 Mbps.
    Both 10bit 422.

    The 4K 120P license is now available (as promised for June).
    There is a slight crop.
    No active or dynamic active stabilization (which also had a crop). 120P crop is about the same as shooting with active stabilization.
    No Clear Image Zoom.
    No All-I. Can use HEVC (XAVC HS), at 280 Mbps.
    No added cost, at least in the US.

    RAW is uncompressed.
    By definition, anything that isn't RAW is compressed with a lossy compression.
    By definition, anything compressed with a lossy compression is lower quality than something than RAW.
    Therefore, RAW is superior in almost all aspects relating to image quality.  Your comment:
    indicates that it's only the ability to colour grade it that is improved, not anything else.  In the context of pulling stills out of video files, all image quality aspects are important and relevant, not just the colour grading aspects.
    Maybe you meant something else, but that's not what you said.

    If you convert the log gamma to ACES CC gamma, which is straight, you can use a master color wheel or master offset control to make accurate changes to WB.
    Another (unrelated) interesting thing to note is that photos tend to be more contrasty than video. Historically, this is probably due to its intended output mediums: print versus TV screen. Even nowadays the default ACR/Lightroom curve is way contrastier than what most video people grade to. Worth bearing in mind for sending photos extracted from videos to a client. And for making prints.

    Shot from 8K 60P (N)RAW video frame. 1/125th second shutter, which is ok for video motion at this frame rate and enough speed for portraits (people micro move).
    "Developed" in DaVinci Resolve Studio.
    RAW video then gives the best of both worlds?

    Thanks for the gratuitous advice. I guess you don't understand scientific method. And also need to loosen up when there is hyperbole. You way overreacte, and you should think why.
    Here is what you do not understand: You can *disprove* my statement that no camera with IBIS can match the ZV E1 stabilization by simply uploading a moving-camera video using only IBIS that is just as good. Simple. That was exactly my challenge to you. And, after your rant, you did just that. Good! The Sony X3000 does indeed have IBIS and that camera-moving clip looks pretty good, but not as good as my ZV E1 video Nice try. I have used that camera too, and forgot about it. I of course was thinking about serious cameras that people generally discuss here. But, yes, with a tiny-enough sensor IBIS can work pretty well, as you show. The ZV E1 has a full-frame sensor.
    Here is my gratuitous advice to you: no matter how annoying a post is to YOU, that does not give you license to provide personal criticism. There is no excuse for ugly posts no matter what. Stick to what you think you know about technical aspects of cameras (which I have learned from). And post more videos. One has to be very brave to post videos here, given the incredible defensiveness and arrogance and pretentiousness that sometimes pops up (the hate for 60 fps was amazing).

    Exactly the opposite you want for sport.... shallow DoF is key as most of the background is quite distracting.... you would probably not see any pro sport shooter with m4/3...

    A couple of examples from today, 8k RAW 60fps 300 2.8 1/2000, imagine these at 150 5.6 they would not pop..... 







    At the end if you want large DoF and portable why not use a phone? But if you want photo and video that pop a R8 or similar + EF adapte + used EF 70-200 2.8

    Btw the new helmet AF of the new R5c firmware is really good, not perfect but really good.

    For track and field, if you shoot laterally by either tracking eg. gimbal moving in parallel or from a fix point by panning the sense of speed will be very different depending of frame rate and shutter speed.

    24fps 1/50 will look like they go much quicker than 60fps 1/120 or look even slower at 60fps 1/500. Even when taking photo only panning laterally  you would always want to have some slow shutter speed so 60fps 1/120 will yield good pictures.

    Now if they run towards you and your camera is not really moving eg. tripod or handheld, it will not matter that much if is 24fps 1/50 or 60fps 1/500 in term of sense of speed. But for photo grabbing 1/250 or above would be required. 

    So instead of sticking with the 180 rule I change the shutter speed based on the position and movements and again if the prio is photo or video or both.

    Some examples of my video grabs:

    Slow shutter 180 rule









    The below one works as the camera is moving (tracking bike) at the same speed as the athlete, if the camera would be fixed it would be impossible to get a picture out

     
     
    High shutter speed 1/500 and above











    For me 4k would be too low as I crop quite a bit and also take vertical photos out of horizontal video. If you would do it a lot to take pictures out a 6k or above would be better in my opinion.

    The fx30 is a good video camera. And 60 fps enables high shutter speeds for both good motion in video and stop-action for stills.
    But it would seem the ideal cameras for taking stills from video frames and shooting videos are the Nikon Z8 and Z9, which can shoot 8K RAW 60p.

    The 28-60 has no OSS. The 24-70 has OSS, so in principle, if they coordinate, there should be more stability with IBIS. I use Active Stabilization for static shots, reserving dynamic stabilization for moving with the camera. I have not tried that (yet) with the Zeiss/Sony lens.

    I dont think anyone in this thread is talking about creative use of the zv e1, except the guy who posts actual videos from it, whatever their worth.
    Putting a zv e1 on a tripod, pressing the record button, and leaving the camera on is not a "creative" use of the camera. Get it? It is a use for sure. So would using the camera as a hammer. Whatever you like.
    I reacted to the continued posts about overheating. Each camera has a best use and a worst use. I emphasized the best use. You can guess what I think is the worst. But if that's what people want to do, just great! Go for it.

    The ZV E1, paired with a good lens, like the Zeiss 24-70 f4, does really provide a nice image. And that sticky tracking focus assisted by AI really works and is needed here (the dancer moving and turning, for example).
    Here is Hare Krisha at Washington Square Park.
    Oh, and the audio quality of the camera is above the usual.

    Well let's face it, everybody likes to save money no matter your income. So when the Sony shills on YouTube are out there spinning the ZV-E1 is an A7S3/FX3 for almost half the price, eyebrows get raised. What's the catch? Well its quite simple, Sony stripped the camera to its bare bones and it overheats during long takes as result. And the shit show commences.
    Overheating is a controversial subject. Most people I think feel a camera past a certain price point shouldn't have such limitations. Sony did put a lot of effort into making sure this camera is identified as a VLog camera. It's not in the A7 series its ZV. And I guess that for its intended use, the camera performs to satisfaction. So why the fuss?
    Because price aside, there are a few cool things about the ZV-E1. It has features neither the A7S3 or the FX3 have thanks to the AI processor. The AF is really impressive, it has breathing comp etc. Also the touchscreen supports gestures etc. The camera just feels snappy and the AF doesn't skip a beat no matter what you throw at it.
    So in a few ways, the ZV-E1 kinda feels like an updated A7S3/FX3. And that's rather alluring, especially in the US at its price point. But that's when reality hits and you must realise its a vlog/travel C-cam intended for short takes. If that's your method of shooting, well you're in luck. If not, its probably going to be a hard pass. Its as simple as that.

    Seriously, guys. Overheating? Do you take long, boring takes from one position? That's what you shoot?
    I have shot short boring takes in all sorts of hot, muggy conditions and the camera did not even get warm.
    Anyway, for the first bright sunny day since I acquired the camera, I used the upgraded Sony FE 24-105 G lens to shoot an HDR video. New lens firmware, out last November, is alleged to have improved stabilization coordination with the A7R V - but since the ZV E1 has the exact same processors as that camera, I thought I would try the lens out.
    And no overheating. I guess I have to keep saying this...

    I am not the "one person" who does not understand the different uses of cameras and techniques.
    What I do not understand is why anyone thinks this camera is suited for mounting on a tripod and shooting video for an hour. Nothing wrong with the use, what is wrong is thinking this camera is at all suited for this purpose. Get over it already. It is not. 
    There is no point acquiring a camera whose most important feature is compactness for mounting on a tripod and shooting video for an hour. Obviously. Get an fx3 and be done with it, already.
    The ZV E1 camera is for portability, handheld use. For relatively short takes; not 5 seconds, but not 10 minutes either. In any temperature. Would I prioritize the camera in non-pathetic 105 F temperature? No.
