I've got a bit of an old fashioned view on this which is that instead of everyone else running round like blue arsed flies that perhaps Canon themselves might want to have a go at it themselves.

How about we turn the camera on, do nothing with it, leave it in the menus.
Put it in the freezer.
After 1 hour, see if the timer has ticked down to 0 mins of 8K.
Who wants to see an OVERHEATED! SHUTTING DOWN! screen with frost on it?

EOSHD testing finds Canon EOS R5 overheating to be fake, with artificial timers deployed to lock out video mode. In this test, we will probe my Canon EOS R5’s actual internal temperature in Celsius, as reported by the firmware.
This week CDA-TEK and I are developing an Android app for the Canon EOS R5, which connects to the camera via the Canon API...

So going back to the actual internal design of the EOS R5...
The questions Canon need to answer are:
1. Why is a circuit board sitting between the main CPU and back casing, blocking the heat from spreading away into the chassis
2. Of course, why is there no thermal conductive material on the CPU?
3. And why does the RAM thermal pad overlap onto the CPU, but not entirely cover it? (It seems to spread the heat from the RAM onto the CPU which is never a good idea).
4. Why does ice not cool the camera and speed up recovery time? The firmware recovery countdown timer is so slow to go back up and always the same.
And indeed they will be asked via my contact at Canon UK.
And I won't let up until they answer.
If they don't answer, they have something to hide obviously.

That is evident.
Ah so it's ok then. The whole release is hyped as an 8K pro video tool with 4k 120p but because Canon slipped some best-case scenario disclaimers into a CVP video, they're off the hook!
The real overheating data should go something like this:
8K from cold - 20 min if you're lucky
8K about 10 mins into a shoot - 10 mins maximum
8K after a few stills - 5 mins
8K limit after a few stills and the Wifi menu - 0 mins!
And the marketing should say something like:
"Getting through any kind of video shoot, even filming your pet poodle for 10 mins with the powerful new EOS R5??... You'll be lucky!"
That would be far more honest in my view.
But yeah, no false advertising!! Did you actually READ any of the PR or Canon website?
WHY DO PEOPLE NOT READ OR LEARN BASIC FACTS BEFORE SPOUTING OPINIONS???
“On the set of high-end productions such as commercials, dramas and documentaries, the EOS R5 is an ideal partner to the likes of Canon’s brand-new EOS C300 Mark III”
“Set to redefine mirrorless, today’s update confirms the incredible recording capabilities of the EOS R5 including internal 8K RAW up to 29.97fps and suitability with high-end production workflows”
“The EOS R5 boasts features seen only in high-end cinema cameras many times its price point and video features no other mirrorless camera on the market offers.”
“Created as a direct response to growing demand for content creators to shoot both high-quality film and stills, the EOS R5 holds its own as the lead camera in productions – going over and above industry standards and achieving outstanding 8K.”
 
Yeah sure. Sure it does.

Can’t wait for Porsche to release a new 911 with 300 horsepower and a top speed of 200mph and a cruising speed of 100*
 
 
 
 
*top speed only achievable on a cloudy, 24C day. Cruising speed is only for a max of 30 mins, except when in 6th gear max cruising time is 15mins. 5th gear allows unlimited cruising time but suspension is disabled and top speed is disabled.

This should be the new Canon slogan.
"And if you can get any video with this camera, its a bonus."
Let's see how many sales that gets them vs 8K RAW!

If only Canon told us this when they first announced the camera at the start of the year.  Instead of all this lovely news of 8K and 120fps 4K, and how it would unlock our filmaking, they had instead simply said -
"And if you can get any video with this camera, its a bonus."

But it’s not a bonus. Even if they didn’t market the video the way they did. You literally can’t use your “bonus” most of the time. You don’t sell someone chocolate and say actually you can only eat that for 3 seconds and then you have to wait to eat a little bit more. And you don’t include 8K RAW VIDEO if the design is inadequate to actually operate it. If it was a stills camera first, then you simply don’t include those video features at all. Basically what they did with all their other 5D cameras.

Someone should tell Canon’s marketing department that.

Nope. I do however have an R5. My intended usage is shooting stills, and for that it’s one of the greatest cameras Canon has ever made. The fact that it can record any video at is a bonus.

Analogy time: If you paid half a million for a Lamborghini that was advertised as having a 200+ top speed, but could not actually maintain that speed for more than a few minutes and in fact couldn't go more than 100 MPH most of the time and would overheat constantly and leave you stranded on the side of the road, would you be satisfied with your purchase? Your expensive italian supercar just fried its own V12! 
That's basically what's happening here. There's a considerable gap between what's advertised and what was actually delivered. This didn't happen overnight. The fact that people kept using Red and Black Magic cameras despite serious reliability and built quality issues has emboldened companies like Canon to overpromise and under deliver. The difference is that the aforementioned companies are upstarts and Canon is a 100-year-old imaging behemoth. People expect industry leaders to put out solid products and not pull shenanigans like this.
Oh well. There's still Sony, Panasonic and Fuji. Oh, and Arri for the folks with deep pockets.

You are wrong.
I cannot legally advertise a product I've made as a professional cinematography camera, when it is in fact a banana.
I cannot please my customers or make good business selling something as "8K capable" when it isn't.
To say every company does it is just not true. In fact if they tried it, they'd be on wrong side of the law and wrong side of their customers.
Can you imagine the fury if your iPhone started overheating 1 hour into the day and you had to turn it off for 30 mins?
I am very baffled as to why you think Canon can get away something similar... because it's a camera.
No, they advertised it a certain way, and even the late admission of heat limited recording times is misleading because of how the camera behaves 10-20 mins after being switched on, or 30 mins into a stills shoot.

This camera is such a colossal failure, even if the issues get miraculously fixed somehow, I would not touch it with a ten foot pole. Not even for personal projects. There are way too many good options out there to justify spending $4K on a glorified hand warmer.
I honestly think that one of the reasons for this debacle is the entire marketing culture than has sprung up that demands flashy specs over rock-solid reliability. I also think that the race to miniaturize cameras has created new challenges for engineers, and this in turn creates conflicts. One of the reason why the Panasonic S1H is so good as a professional tool is the sheer size and heft of the thing. It doesn't feel like a toy that can be slipped into a pocket. Professional tools should be built like hammers. A little bit of weight is not a big deal. It's still a far cry from a 16mm film camera or a Betacam. Get a bigger gimbal and a beefier tripod.

This thread details the teardown process, modifications made and some important findings:
http://c.tieba.baidu.com/p/6848700307?pn=1


He replaced the two thermal pads that did not fully cover the CPU with a dollop of thermal paste and noticed significantly better and more even heat dissipation.
Most important finding: despite the temperature drop and improved heat dissipation, 8K/4K HQ still cut off at 20min mark, suggesting a firmware limit is also in place.

Philip Bloom is - by his standards: unusually - outspoken on the R5:
"This is the first camera I have used in memory that punishes you for using it. [...] I spent £4200 on a camera I cannot use most of the time and that’s ludicrous! I truly hope they find a way to fix this debacle."
 
 

At the weekend I bought the enigma that is the EOS R5 for myself. Foto-Meyer in Berlin were able to find me a rare unit. A huge thank you to them! What all EOS R5 owners have in common is that they have paid a lot of money for a professional video tool. We pay the money, we get to decide what happens next, and I'll be reaching out to Canon and making this clear. We need to ask them to work on a solution for overheating. It's worse than you can possibly imagine.
Just need to get something straight - my purchase is NOT an endorsement of the EOS R5. I bought it purely to cover the camera on EOSHD and to help work on fixes for the many issues this camera has. It is in no way a dependable tool for 8K, RAW, oversampled 4K, 4k 60p or 4K 120fps in the state that it's in. At the very maximum it is a pixel binned 4K 30p camera similar to the Sony A7R IV with the benefits of Canon's colour science, 10bit codec, top LCD and better ergonomics. Actually that doesn't sound so bad does it?! But this is not how it's sold to us - it is supposed to be a $4k all singing, all dancing, cutting edge 8K/4K video tool and that's how it should perform in the real world.

Hi,
I found great plugin for you guys to check out. It seems to work find in Resolve (the current new 16 public beta version, I'm on the Studio version).
Boost by UrsaDSP is a compressor, limiter, upward expander and saturator.
What it allows you to do is to make your tracks sit in the mix by bring your low volume information up, compressing regular volume information and limiting the peaks as well as choosing to enhance the signal further with saturation (labeled Drive) which is available when you turn off Punch which is transient enhancement (which I am not currently using, I use Drive instead.)
UrsaDSP plugins is distributed by Devious Machines at deviousmachines.com, where you can download the demo. They also have a discounted intro price of £39.99 (about $52 when I purchased today).
Anyways, I find making things sound louder and better at the same time is a difficult problem to solve.  From my experience Boost is fantastic a solving this problem.  It can also be use across your mix, though I have not tried it on a full mix yet.  BTW - I have no affiliation with UrsaDSP, but they have been responsive on the Gearslutz forum when I found out  about this plugin.  Video below...
Finally, it is super easy to use.
 
 

no K for $4k what a deal
