We can debate your first point (the president of IBM decades ago said “I think there is a world market for about five computers.” Many said that man would never go to the moon. The "impossible" has been made possible again and again with time and determination), but it is the second point, the one in your quoted paragraph, that says it all. There absolutely is value to higher DR in a camera. Just think of the DR on digital cameras 10 years ago and the tools we had to manipulate DR and compare it to now.

I agree. We can't foresee what in-camera and post process computational engines will be able to do with a more encompassing data-set (image) in the future. The more granular we can digitally record the analog world, the better!

I will say that I can record raw video on both the 64 and 1258 even though it shows as not supported. The largest card I have is 128, so I know it works. I am headed off tomorrow to try some video. I will see how much each actually does.

Nikon shooter and heavily considering the EOS-R5 as of lately I'm shifting toward more videos. Not a big fan of beta testing, so I'll wait a few months after release.

Perhaps the incremental costs of adding video are small compared to base price of producing the unit. Perhaps not. How much extra R&D went into designing the camera to offer top of class video rather than video like a 7D MII or a 5D IV? Were more expensive materials used within the camera than otherwise necessary to aid in heat dissipation, or tolerating the higher heat? What other considerations might there be that I, not an engineer, wouldn't even think about?

I did mention two considerations; the other being perceived value, which you actually allude to as well. If you think

I am cautiously excited about the R5. I would absolutely love 120fps in 4k. Though I think when it comes out, I'll rent one and compare it to what Nvidia can do with a GPU generating slow motion from my Z6's footage.

But you mentioned heat. I didn't read this entire thread so I apologize if I'm bringing up a topic that's been mentioned before, but I actually only saw this morning that there will be an HEVC option. I can't fathom how they will pull this off. My desktop computer, with a full custom water cooling loop, with a 360mm radiator, and a total of 6 120mm and 2 140mm fans in an air conditioned room, with a Ryzen 3950x (that's 16 cores and 32 threads) can, with an overclock, encode 4k at about 9fps, and the CPU touches 90C. I get about 8fps without the overclock, and the CPU hits about 75-80.

If I hand the encode over to the NVENC, I get about 50fps encoding, but that's a full desktop GPU being directly fed cool air, 3 120mm intake fans blow directly in to the thing, and it hits about 70C during an encode. Also, during an encode with that GPU, Davinici Resolve hits around 90GB of RAM usage.

I don't think that Canon has defied the laws of physics, so there is SOMETHING going on here. 8k footage to HEVC, if it can be done at these frame rates for a sustained amount of time, they must have really come up with something special. Though I'll remain skeptical until I see it in action.

Custom ASICs. A GPU is still general purpose. A FPGU would be better. An ASIC is best.

Dude, what ASIC can make that enormous of a difference? I mean, yes, they are inherently specialized. But that isn't a tiny improvement over what a GPU can do, that's orders of magnitude better than what a GPU on a top of the line process node can do, which I can't see Canon being able to afford for this application. I can't find anything below about 30-40W TDP and they can't do 4k past 60fps, and they're the size of a full size PCIe card.

Well, dude, I don't know because I work in the software and not hardware realm, but at one of my prior camera companies we used FPGAs over GPUs because of their huge performance gain for the task at hand. But I'm not the hardware guy.

Either they're lying, which I find unlikely, or their chips (ASICs) are indeed better (for this task) than your GPU. I have a hunch that the image quality will be decent, too, or they'll be the laughing stock.

Because you aren't just moving raw data. The camera is doing the type of stuff you are doing when you just take photos from your memory card and put it on the hard drive, only without all the extra cables and connections. I don't see how anyone would think that there would be more than a few minutes of 8k record time at once. Does anyone think they're going to give 30 minutes a pop?.

Indeed, when a Samsung smartphone can record 8K video on the fly in H.265 at 24 fps, I think there is a decent chance that Canon can pull this off too. The quality would have to be higher of course. As a matter of fact, I wouldn’t be surprised if Samsung might be involved in the manufacture of these ASIC, they have a very advanced process tech. I think Samsung is also using Dual Pixel AF, so.... maybe som cooperation?

As good as the R5 sounds for video, I can't wait to see what the specs are like for still photos.

And what additional features are built into the body?

I'd love to see focus stacking an integral feature like it was for the RP.

Based on the 1dx 5.5k raw bit rate, which is ~2800 Mbps, or about 1 GB every 3 seconds. So about 6 min of record time for 128GB card or 24min for 512GB. Even if there is no software limit, one would run into storage limits.

I worked in DC for many years where the culture was rife with the use of the of what was called a peeing contest. I see where it has evolved to prime time tv. You guys are amateurs. I began flying in a WWII T-6 and wound up flying using glass cockpit displays. I used Bronicas and Canon film in a wedding business that I opened after I left DC. What I learned from my tenure in DC was to do the best I could with what I had in hand whether it be a camera or an airplane to produce professional results and to stay out of fruitless and useless attempts at trying to prove my manhood. .

Um, you aren't showing the full dynamic range when "the dynamic range of the original per unit area is reduced."

Like I said.

The brain nevertheless perceives the scene details in each area even if this is based on scanning the scene and some kind of processing the data. When you're looking at e.g. brightly lit backround with your fovea, you see its details, and when you look at an animal in the shadows, the brain sees the object, and forms a memory of the scene parts as when they were looking at them directly (in their adjusted form). A good print accomplishes
...Show more

You are really missing the point here. In order to do what the eye does with a high dynamic range scene you must do precisely what I said you'll do — reduce the overall dynamic range of the original scene by making the darkest areas lighter and/or the lightest areas darker.

If you made a print with the actual dynamic range of the original hight dynamic range scene, it would not work because your eyes aren't going to adapt to the different areas of the print the way they do to the original scene.

Remember, you eyes cannot actually see the entire dynamic range of the scene at once when you are there looking at it. If you look into the dark shadows, your pupils dilate to send more light to your retina. You don't notice that the bright areas are getting brighter due to the way our visual system works. (You can notice this if you move your gaze quickly between very light and vary dark areas as it takes our pupils an observable amount of time to change. ) When you move your gaze to the bright areas your pupils close down a bit and at that moment you would no longer be able to see the same details in the dark areas... until you move your vision back to the shadows and your pupils dilate again.

When we do with a print (or over presentation) of such a scene is we lighten the dark areas and/or darken the bright areas so that the entire image, now with a compressed dynamic range, fits within our visual dynamic range without having to rely on the active changes in pupil dilation.

My prediction (and desire for a bit) has been that prints will be displaced for a number of use cases by Screens. Oleds and other technologies as they get more cheaper are a very viable replacement for prints. My main room tv is now a few years old, 1080p 65'' and just having screen saver be photos has been a gift. Over time as budget allows, I expect to replace all prints with screens.

This was a good and thoughtful post, but it highlights the need of what I would (sadly) describe as a dying breed: large prints. I mean I loved it when Calypso was still in business (in my home town no less), when I could print 80" wide. I have a 60x40 RA-4 print hanging over my home office desk, made with a 1DS no less. But I have exactly two of such prints in my home, because I don't have that much wall.

What I do have however is three laptops, and one iMac Pro with an attached 6K XDR display.

Waving hand over here...... yes it is possible.
It happens probably ever day.... well before the covid19 thing.
also not 8K but at least 6K.
Blackmagic pocket CC 6K will out put to a 1 TB or 2 TB SSD. granted these are fast (580 mb/s) as to not drop frame rates.

I think you are talking about 2 different applications.

one is moving data from a cmos or type of sensor for light gathering, processing the analog signal into digital information followed by saving to a digital media.
This is being done on a closed loop, highly controlled electrical path.

The other is taking digital information, manipulating (editing) + adding special effects and then transcoding to another format.
These are apple to oranges comparisons.

Also... why do you think company that produce pro/cinema rendered footage have large server farms ?

It's still HEVC encoding, I'm not talking about adding effects, of course something that intensive slows the encoding, because that's not all it's doing. HEVC compression is a very compute heavy task.

That's a possibility. And yeah, Samsung has about the best process node out there. I don't think Canon would have the volume to put in an order with someone like TSMC, but if they have a partnership with Samsung, that could be the ticket.

Well, no, it's not like copying files at all. But anyway, if the only limitation is that record time is a few minutes at once, that's fine with me.
