Yes that's true. Lot's to try next. I'll see what state the clip is in and see if I can still transcode it in EditReady. The 8K HEVC is a bitch to edit! So I'll be doing this anyway with 8K material to ProRes. The main goal for me is not so much the workable workaround but rather the truth gets out, and to force Canon's hand in removing any artificial limitations. Your contributions here have become invaluable, so thank you. Yes this could indeed work but it'll be beyond the patience of most filmmakers I think. I'll try @BTM_Pix's suggestion first and see if there is a simple way to get around it and produce a usable last recording...

Looks like somebody has been right?

Magic Lantern just became Magic Screw. Tried the second test differently. Found a way to get the full record times back: https://www.eoshd.com/news/canon-eos-r5-so-called-overheat-timer-defeated-by-a-single-screw-in-battery-door/ You're only supposed to blow the bloody battery door off!!!!

On Friday, I received a message from the lead developer at Magic Lantern. An interesting theory was being put forward by one of their open source contributors, which he believed could defeat the so-called overheat timer on the Canon EOS R5. Initially I was skeptical as to whether it would work! Mainly because the initial real-world tests on my own EOS R5 did not reset the timer. But then, a break-through.

It's worth another look. Quite a few variables and ways to do it. I haven't had the time try everything to be honest. The guy on YouTube has tried pulling the battery during a recording, and got 5 mins remaining. I also got 5 minutes remaining, but stopped the recording first. I thought at this point, if the timer is in RAM then it should go up to 20 mins in 8K not 5. Then I went out and had an ice cream with the girlfriend. So tomorrow maybe I should put more effort in!?

It has parallels with the world in general. We have in Russia today a dying man who has been horrifically poisoned, screaming in agony on a plane and straight into a coma from which he may never pull out. Leader of the opposition to Putin. The RT news anchor tosses the peasant people some lie. "It is low blood sugar. Always carry candy" The low effort of that bullshit, and the distain for the intelligence of the general populace. And it is the same thing with Toneh. Toss the peasants some badly research bullshit dressed up with a whiteboard zapping key phrases at the audience. Pure clickbait. Pure cynicism. Ah you stole the idea... Nobody will notice. Just say you forgot. Whatever. Who cares. End of days stuff my friends. Thank you to all on here who have helped research and inform on the overheating findings these past few weeks.

Amazing how easily people are fooled. Suddenly Tony is considered the source. Makes me fucking sick.

Breaking news... His source was actually the well known EOS DH. The famously relaxed guy who doesn't mind being ripped off at every turn and his journalism work uncredited. The DH stands for "Die Hard" as in die hard Canon fan, loyal to the bone and willing to pay $4000 for broken shit. Not a cross word spoken. You know... A bit like how TONEH is with Sony. I think myself and BTM_Pix deserve a credit and apology in TONEH's next video? Don't you? Let's make it happen. And come up with a little plan.

EOSHD tabs in his browser...

"Breaking news" And people wonder why I take issue with so many YouTubers.

Yeah, I don't pay $4000 to have to reset a cripple clock or disassemble the body. Over to you Canon! (That doesn't mean to say we shouldn't continue to explore and investigate. I find the workarounds shed light on the camera's design and behaviour, which allows us to hold Canon to account with hard evidence).

I have shot a comparison between the A7R IV and EOS R5 myself. Blog post coming up. The A7R IV has the sharper looking 4K and is very good in low light. 8bit not too much of a hinderance really. The EOS R5 is much softer in the 4K mode we can actually use (pixel binned) but has less aliasing, and moire is well controlled. It's alright. Does it let Canon off the hook though? Nope.

You are talking informed armchair shite. YOU have not taken a single shot with YOUR EOS R5 and reported anything here of value. YOU have not taken the back off like some people, and even measured internal temps with an infrared thermometer. A heavy load for an Intel CPU is 90C. I have a laptop that registers even 95C during rendering. If the CPU goes above this it will throttle to maintain 90C-95C. Only if the temperature carries on rising, is it a risk. 90C is fine. Fans and heatsinks in a PC are only there to maintain stable temperatures - to dissipate heat - for very hot running components that use a lot of energy. A smartphone does not have a fan, as the energy consumption is lower and efficiency far higher - these kind of CPUs are RISC as is the ARM based CPU in the EOS R5 and R6. The EOS R5 maintains a stable temperature below 65C in all video modes - this is not conjecture, it shows in the PCB temperature sensor and EXIF metadata, infrared thermometer tests, and just plain old application of common sense. If the EOS R5 can run at "heavy load" in 8K for 10 mins... what's so special about the 20 min point at same temperature that it has to shut off... Nothing. It's a timer. And the recovery times are even more artificial. If your laptop can render 8K for 20 mins at 65C it means the temps are stable and plateau at a comfortable level. Same with a camera CPU.

Just tried this as well. It does forget the aperture because it didn't write it to NVRAM in time if you pull the battery quite quickly - I tried after about 10 seconds, with the battery door open and a small screw lodged in the pin to force the camera into ON state even with door open. It does not forget the timers That seems to work off a separate clock to the main date / time and is constantly ticking away like a quartz powered by the button cell. One solution I wish the Chinese guy had tried is to permanently remove the internal battery and see if the recovery timer is reset every time you reboot without it. It would be annoying to be kept asking to input date and time on every startup though.

Let's be honest, these stupid workarounds are not practical on set. It is up to Canon to fix the damn camera, not us. We paid the money, and not a small amount. Unscrewing the back, prodding the card door sensor, ripping the clock battery out... None of it is acceptable for $4000

We tried this via the Wifi App by @BTM_Pix It just changes the data and time, it does not reset the separate clock used to measure the camera up-time. I can confirm Magic Lantern are looking into it.

58C for 45 mins in the special "not limited by heat" mode!! But what's a few degrees C between friends when you want to sell a C500 II, right?

I see it plateaus around the 57C-61C mark for 15 mins. So it can roll along just fine at 60C for 15 mins... But come the 30th minute of thou hour, the great Thermal Christ beams down from Cripple HQ to read us the Ten Commandments.

Please remember to check all the previous articles and topics before you mention the sensor. A) It runs doing 8K readout for hours when external recorder is attached B) It's been measured with an infrared thermometer C) The visible image noise doesn't increase between 10-20mins in 8K recording, let alone after 4 hours D) The R6 has similar overheating timer, even though the low resolution 20 megapixel sensor (similar to 1DX3) is only doing 5K/4K readout

I don't know why it doesn't go above 64C. We are not semiconductor engineers at the end of the day There are probably thermal throttling things to add into to the mix, the situation is probably complex. But there is now mounting evidence that Canon has been completely bullshitting us. And just to have these limitations in the first place is disappointment enough and loses them a ton of business. Zero apology. Possibly shifty, secret recall. Saving face. Lying. Honestly I don't feel like giving any more money to them, do you?!

Sometimes I lose faith in the camera industry completely and think about moving on. Maybe do smartphone camera reviews, now they are at enthusiast level and really quite unique in some regards. But then I realise there is just so much immorality, face saving and arrogance everywhere I look. On the streets, in people's personal lives, in businesses up and down the country, around the world, small and large, that any efforts to correct this or open people's eyes in any small way is basically a teardrop in the sewer.

"Math Class" on Baidu now has extensive infrared thermometer readings of the camera's mainboard with the back off, showing they correspond closely to the temperature reported in the EXIF data and don't rise above 64C. His next finding is that if you remove the internal battery it resets the so-called overheating limitations. So who is telling the truth now, Canon?

Huawei P40 Pro has RAW capture on all lenses but RAW capture on a phone looks considerably worse than the composite images made by multiple frames and computational photography. 10bit HEIF > RAW on a smartphone. Sony makes average cameras at best on their smartphones, and to be honest average smartphones in every sense. P40 Pro Plus, P40 Pro, Xiaomi Mi 10 with 8K, Oppo Find X2 Pro, those are the ones to beat on the camera front. I'd avoid Sony like the plague for smartphones.

I shall nickname my EOS R5 "Boris 5"

I believe him. https://www.eoshd.com/news/silence-of-the-recall-is-canon-turning-around-shipments-of-eos-r5/
