Matins 2

Keep us posted! ML needs interpreters for us plebs as it's a bit esoteric 😂

I was the same when I got mine. I don't understand how people can enjoy using those modes... Maybe if you had an optical view finder it could be fun.
 Now though, I never shoot more than the 1080 Rewire option. It's non-crop (other than the aspect ratio) and realtime live view. If you shoot this way, it's basically the og BMPCC with a bigger sensor and much better audio / battery. If you run through MLV APP and convert each clips to DNG frames, there's barely even any extra steps in post.
As far as my test of the new builds goes, the live view in the higher resolutions and crops is getting to realtime, but they're refining it. Give it a few weeks and come back to it.

Here is an article showing that human cells die rather quickly in extended exposure to higher than 43 degrees Celsius:
 
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4188373/
 
When human cells are at 44 C for a period of 1 hour, only about 10% of the cells survive (Fig. 1).
When using external recorder, Canon may have assumed that the camera is no longer hand-held but used on a tripod, since it would be pretty clumsy to hand-held the camera with recorder attached. Thus there is not as much likelihood of long-term exposure of the videographer's hands to the damaging heat when using an external recorder. And yet Canon have probably considered the needs of professional videographers here, and allowed external recorder to be used for that reason. A consumer is less likely to be informed about low-temperature burns and may be hand-holding the camera as a matter of course, whereas a professional may be using tripods and external recorders more frequently. It's a balance act between safety for the typical user and utility in a professional environment.
 

43 C is regarded as the limit of temperature that is safe for human tissue so that it's not damaged due to the heat. That's what is used in medical devices as the safety limit: during use, the device must not heat the tissue temperature above 43 C. If the temperature of the skin does rise above 43 C then you can expect some damage, though I don't know how quickly it happens or how severe it is. Roger writes "we ran it for 18 minutes before getting a temp warning. The hottest part of the camera was the back behind the LCD door (43°C / 109°F)". So it seems that the 43 C tissue damage threshold is indeed what Canon used to design their overheating algorithm to protect primarily against, and they're running it pretty close.  (Canon also mention controls for internal temperatures as a secondary consideration in the CineD interview).
 
Of course, if you don't hold the camera in your hands during recording and use a tripod or gimbal, then it wouldn't cause burns. But they seem to have designed the protection for those in mind who do their videos hand-held. My guess is that the 43 C could actually be written into some countries legislation or regulations as well, so Canon might not have any choice about it. I'll try to find some information on this.

I will try to upload the whole boring a7R4 video of this 100+ minute 8K IPB test now after a quick and dirty render.
And about the FW update, I consider it riskier to update my FW then to run the R5 like this. Will they close this loophole, will they cripple my much loved superb Canon EF glass that has never ever worked better on any native body I owned, all to give RF an edge, in exchange for 20% more overheating time? No thanks!

Oh Yes, I forgot someone all right, Andrew Reid, how could I, thanks Andrew!!

Still testing after 1 hour and 15 minutes, first overheating warning consistently appearing after 16 minutes, battery pull between 17 and 18 minutes. Temperatures stable. This could go on forever I have the feeling. When to stop?

It works! 15:00 again and the R5 is now recording its second 15 minute run. I am policing the outside and card slot temps, colder than with CFE and RAW, but that should not be a surprise. We'll see whether I am brave and foolish enough to let this abuse carry on for a full hour, we will find out within the hour 😉
162MB/s?? Peak rate? It's 680Mbps, so should be 85MB/s. 47 seconds for a 4GB chunk also give 85MB/s. I need to re-format the cards between runs, because on the first recording start, the R5 gave the card slow error after 10 seconds. I immediately restarted the recording. So let's see. I have two 128GB and one 256GB UHS-II cards that are fast enough for 8K30 IPB.
8 minutes into the second recording on the 256GB microSD everything is fine and dandy still, after the first card slow message. Sandisk 128GB is formatted and ready to go.

As is wrote above, despite 60W of Peltier cooling power supplied, with a copper heatspreader covering the whole back of the R5 behind the LCD screen and cooling it to -5 degrees Celsius, risking internal condensation, it has ZERO impact on the time I can record in 8K RAW, with my R5 with firmware v 1.0.0.
I was willing to walk around with this ugly contraption if it would give me longer recording times. I need a full NP-F970 battery per hour for the maximum cooling. I doubt Tilta will apply that much cooling power.

Canon deserves a good hammering in court.

Unfortunately, maybe it is the case. In the stills foruns that I look, people are giving a damn about the issue and just wanting to know when they could buy it.

Only chance is a class action suit - japanese people do not like that kind of thing.

ProAv talking about overheating, and customer response calls... The confusion of the R5.  It's all weird! 
 

If it's deliberately implemented, it won't get a recall. Instead, they'll throw a bone (e.g. extra record time), and allocate more resources for marketing.

Canon really threw the kitchen sink at the EOS R5 specs sheet. What about the kitchen fridge?
Canon have stated overheating time limits for HQ video recording in a warm 23 °C room.
How does the camera perform in much colder conditions?
Does the EOS R5 still overheat in the Wifi menu in a fridge?
Or do the cold temperature help cool the camera body, which Canon claims act as mitigation for hot components inside?

It's not 5%, it's been updated to 0.2%.
I downloaded it, and it's just boring website assets like product promo videos, marketing copy, layout designs and stuff, from years ago.

Although I'm not particularly interested in phones, I somewhat liked the iPhone 5c for some picture taking. 

 

Andrew....I have said this over and over and over again. The heat condition of the R5 is not an engineering "mistake" on Cannot's part. It is literally doing exactly as it was designed to do from day one. Cannot wants the R5 to be used only in specific ways and this does not coincide with the way "we" want to use it.
We have a need that we want the R5 to fill. However, Cannot wants to sell us a different camera for our need.  Yes, the firmware is deliberately highly restrictive. They are actively "steering" their customers the best way the know how with these crippling tricks.
As customers, we need to stop thinking the R5 was an engineering mistake and simply let accept it as a casual camera that has zero overlap with any of their true camcorders.
Cannot will never stab their Cine EOS team in the back....no matter how bad we want them to. If anybody thinks the Cine EOS team doesnt care about the R5 and was not in many of the R5 devopment meetings and planning discussions....you are crazy!

Philip Bloom just posted this on his Instagram account:
”Shooting real time sunset on #elenibeach In Skiathos with the @canonukR5 and @sonyalpha A7S III so I can put them on my tv when I am home and pretend I am there. 

The R5 managed 26 minutes in 4K HQ mode before shutting down. Now it’s recording in 4K line skipped mode. I just need to watch for that 29.59 record limit. 

The A7S III is recording 50p 4K 10 bit. It’s been going for 90 minutes now, zero issues.”
”I can sum up what filming with the @sonyalpha A7S III on holiday is like very succinctly... 

It’s just easy, you don’t have to fight the camera, everything works beautifully and the image is just gorgeous. 

If this camera was capable of high resolution stills it would be the perfect camera. As it is this is a superb small beast of a video camera. There’s nothing else out there that comes close to all it does. I will be very sad to give it back at the end of my holiday. “
 
 

How much did Canon pay for this FUD campaign?
