DPReview TV: How to set up your Canon EOS R5 or R6

Davidof_CR,
I asked, although I knew the answer, because I was curious to know the reasoning of the OP.
A possible restriction could be that a narrower mount could lead to a narrower image circle. And the sensor must not move out of the image circle.
But most of the time, a lens can project an image circle with a greater diameter than the mount, so this is not a problem...

Exactly. Manuals aren’t good at that. Video usually explain ...best for what.

@ dr.noise: For thoose who want to learn the functions and settings of their camera to know, I agree fully with dr.noise.

For those who think a few quick settings will fix everything, and don't spend time on how the learn the camera to know, a video might be seen as a "good enough" solution. I would look at this approach as an ok start.

The camera comes with a basic 200 page manual.
The "advanced" manual is 900+ pages and you need to print it unless you like reading off the screen and there's no real index as such.
Even with an index you need to know what it is you're trying to find out and without knowing what the manufacturer has called a feature that you think the camera may or may not have then you're stuffed.
The manuals are not that good in several areas either and although I'm very much a technical person have had to ask the odd question on forum just to confirm what I thought.

I see no problem watching a video, reading a manual, asking a friend or anything, If you find what you need then that's all that counts.

Any decent photographer talks to other people about what settings they like on their camera. Any rational person knows it’s best to get multiple viewpoints and then make their own decision from there.
Anyone who only reads the manual and doesn’t talk to anyone else or watch video, is making thing harder and possibly missing some good tips and tricks.

Getting people up to speed quickly so they can enjoy their significant investment is exactly the point of this video.
Manuals are comprehensive but at times not particularly clear.
The manual and discussions with others are useful but the quick start ensures that the experience is not poisoned.

Instructions are an infuriating mix of "well, duuuuh", "wait, you mean I can just..." and "eh, who needs this?" depending on whether it's too basic, too esoteric or in that Goldilocks zone of things you wish someone had told you. I don't blame DPR for trying...

I think for a lot of people tutorials like these help them get started and to think outside of the box. For new users to system, a starting place can be good. With all the customizations bodies have these days, it's like being given an empty house and a truck full of furnishings. It can be a daunting task to decide how to configure things, and set-up tutorials can be a great starting point.

For other users, it’s can be good to try something different or to discover a more efficient way to do something. As bodies evolve, trying a new configuration can keep one from falling into the rut of jamming an old body’s configuration into a new one. And sometimes there might just be a neat trick you didn’t know about.

Every time I buy a new camera I seek out suggestions from others who have more experience than I do setting up this particular new camera. I find that today's cameras are far more complicated than ever before, so I do not think I am an idiot because I look for help setting up an electronic device whose owners manual runs 652 pages long (at least that is what my 5D Mark IV manual is).

Admittedly the visual can help

@dr.noise
Shutter angle is the relationship between shutter speed and frame rate. A 180° (the most common) shutter angle requires you shutter speed be exactly half your frame rate. (I.e. 30p with a 180° shutter angle gives you a shutter speed of 1/60s)

Different shutter angles have different effects on video footage. A 90° shutter angle requires your shutter speed to be a quarter of your frame rate, and a 270° shutter angle requires your shutter speed to be three quarters of your frame rate.

DPReview did a video on it a while back.

Dr.noise: the shutter speed is set after adjusting the frame rate to satisfy the 180-degree shutter angle rule, i.e. that the shutter speed should be 1 / (2 × f) seconds, where f = frames per second.

So at 24 frames per s, the shutter speed should be 1/48 s, and at 50 frames per s the shutter speed should be 1/100 s. Therefore when you change your frame rate, you also have to change your shutter speed – unless you can set it by shutter angle.

(The purpose of this rule is to ensure motion appears smooth by blurring individual frames in proportion to the frame rate; if you disagree with that, that’s a whole different kettle of fish, but it’s a long-held convention in cinema and video.)

On my much cheaper Panasonic camera, I just set the shutter angle to 180 degrees and it preserves this as I change the frame rate. These Canons don’t allow that because Canon wants to protect its “cinema” line of cameras (not actually used for cinema).

Protecting the cinema cameras also explains other features of the R6 and R5, e.g. the Micro HDMI port (guaranteed to fail if used regularly with a monitor or recorder – it sticks out the side, remember), the lack of waveform monitor for setting exposure, the overheating, etc.

Well, you can’t expose 60 frames-per-second video at 1/48 s. So already there is a problem here.

Most people are not trying to mimic the cinema look, whatever that is (it certainly involves more than a particular shutter speed). However, cinema, like most good video, seeks to make motion look smooth. To achieve smooth motion at 24 frames per second requires each frame to be considerably blurred. That is achieved with the 1/48 s exposure time. If you shoot 24p video at 1/250 s or 1/500 s instead, you get a staccato effect with moving subjects or camera.

But if you increase the frame rate, each frame can be sharper while still retaining the appearance of smooth motion. Even 1/500 s would seem smooth if there were enough frames per second (about 250, but there is probably a limit of perception below that).

Setting the exposure time by angle, e.g. to 180 degrees (or whatever), automatically preserves this relationship between frame rate and exposure time to ensure smooth motion.

Hehehe.
But honestly, as a Sony user, after watching the video I struggle to see how the Canon menus are less confusing. You just have a ton of options on more lists than you care for on modern cameras. And the "logic" of where you find what option seems to be just as arbitrary (e.g. not being able to directly select HEIF in the Jpg/Raw menu) and the same selection of non-sensical abbreviations (e.g. in the menus on AF settings as you run out of screen real estate).

To the fact that i have used both Sony & Canon cameras, I can clearly state that the Sony menus are a lot more cumbersome and need to be simplified. The need to setup up custom menus on the Sony is a must... and with Canon not necessary.
