No need to create a separate thread for it, thanks.

THIS. You have to hope that people see through it. A lot of them don't. Jordan has no honour in this whatsoever, a bit like the Canon people responsible for and complicit in lying to customers. This is a face saving firmware, it doesn't actually change anything fundamental about the usability or the bollocks segmentation strategy. They are not even being at all generous with us - An extra 5 minutes after 1 hour of downtime on a shoot? Nobody works like this. No apology. Secretive. Won't come clean. If it's fine for the Sony A7S III to have normal recording times why not the EOS R5? Sony has a cine line as well but don't pull this kind of bollocks. Also you'd think with the earlier promises of a firmware update for C-LOG 3 and C-RAW Lite, this would be a good time to make good on those too.

Japan camera sales are in a world of their own a lot of the time They're not very representative of the overall picture. The EOS R5 is the new hot thing (literally) so it is going to sell well at the start. A lot of Canon users out there. A lot of 5D Mark IV owners looking to upgrade for stills and get into mirrorless cameras. A chart only tells you the relative story The absolute story at the moment is one of dire sales numbers due to the pandemic, almost everywhere you look

Thanks for the chart. It's good to have it in black and white that there's only a 6-8C increase in temps after 20 minutes. Certainly not enough to justify the shutdown (let alone a long lockout). And also interesting to see the temps are basically flat for the last 50 minutes after the first 50 minutes. I think if we are going to put credits on stuff by the way, make sure to include @BTM_Pix His app has been key to understanding the temperature status and EXIF temp.

I see. The credits were confusing me, as I thought they'd contributed the data. So it's very interesting that it levels off like that. Would it be possible to change the time axis to show minutes from 00:00 instead of the time stamps? Cheers!

Where is this chart from? Is it your test data or somebody else's? Asking because I want to give credit to the right people, if I feature it on the blog. Cheers EA

Yes there is a good chance Canon won't do anything. That's why it's great to see a workaround that starts off impractical, later turn into a simple fix that can be done on a proper shoot to defeat the timer. I feel with the combined effort of @BTM_Pix, A1EX, Magic Lantern, Horshack, myself and others we may get there. Or at least continue to strip back Canon's BS layer by layer.

Ken. Shall we focus on the technical, rather than opinion soup now. Some promising discoveries.

Christmas has come early this year! Ah I remember Peter, nice guy. He did a video on EOSHD C-LOG as well

Sure will do. I'll send you these via Wetransfer soon - do you want 10bit HEVC or 8bit H.264 - or both?

Hurray at least. This is the important thing, that it gets out there and prompts Canon to rescue the situation as they should And that it gets out there credited to the right people, unlike with TONEH, even better. Never under estimate the power of embarrassment! Firmware update in T minus 10,9,8...

I have been a long-time follower of Roger's blog at Lens Rentals, which gives us not just a rare glimpse inside camera gear, but also an expert eye on construction quality, weather sealing and the repairability of it all when you drop it! To celebrate Roger's latest article I had the chance to put some questions his way, to dive into his thoughts on the 600mm, the potential for a 'universal' mirrorless mount and of course the EOS R5 overheating controversy. Read the full blog post and interview here: https://www.eoshd.com/news/an-interview-with-roger-cicala-of-lens-rentals-on-canon-rf-600mm-teardown-and-more/

@horshack Are you working with the 8K MP4 DAT files, or 4K HQ truncated recordings too? I can send you a few different flavours of file if this helps, might be interesting to compare the different codecs. I also need to test 4K HQ with the battery pull after starting and stopping recordings prior to one last sacrificial short clip to facilitate the battery pull during recording, and seeing what the camera remembers from the previous 4K HQ clip record times in NVRAM and what it doesn't. Card swap is also key to do.

😂😂😂😂😂😂😂😂😂 A CLASSIC.

Thanks Kaylee!! I think we should get a new guinea pig meme going.

Very good point! I am pretty sure the REAL temperature is checked by the ARM CPU and other components though, if not by Canon's firmware... And if the camera gets too hot it will likely hang or crash, so we'll have prior warning if there's trouble. I had no issues whatsoever doing the long 8K stints. Back did not get hotter after the first 10 minutes. By 50 minutes it was the same.

ARM based processors will likely have their own thermal hardware shut down algorithms and protections. I am 99% sure the timer is controlled by firmware, with timing metadata saved to the internal battery backed RAM on the PCB and possibly also to the clip metadata on the card.

Daniel I agree 100% We are customers at the end of the day and deserve some respect and to be levelled with in an honest way!! It really drives me up the wall, the fact that I can break all this news on the blog and in Canon's eyes - I AM the villain right?!!? ME! The guy who said Canon had finally turned a corner, rushed out to give them my hard earned £4200 only to find all my worst suspicious were true. The fact they have not apologised to me or to customers like you after all this investment is a DISGRACE. If a class action happens I would support it 1000% I cannot believe the depth of stupidity at the senior management level in Japan. Why do they feel it is ok to release a product with an "official overheating problem" let alone an artificial one?! It would be industrial level sabotage if it wasn't so self inflicted. I cannot believe how slow they have been to respond with an apology and promise to investigate and fix the firmware. They are actually standing their ground on this?? WHY? Out of fear they might lose a few sales in a niche business division that deals with expensive camcorders? The EOS business is surely bigger and should be pulling the strings, not the other way round.

I don't have one and won't be buying one that's for sure. Soon the R6 will be announced and I am sure people will put it through the same stringent tests as the R5. The field tests I've seen of the EOS R6 so far don't bode well, with cut off times as bad as, if not even worse. It has no fall-back "not limited by cripple hammer" 4K line skipped mode either so it is a 1080p camera basically

Did you miss the Sigma L mount 85mm F1.4? Looks great.

Hold on a minute and listen. We do not have a monster at all. It remains crippled. And in dire need of a firmware update. The actually reliable video modes are line skipped mush. But most of all think about your principals. It pisses me off to be honest when a company has been shown to cheat their customers, but then the customer just goes "ah what the heck" and rewards them anyway to the tune of 4 grand. If you really feel strongly about the fact that Canon have lied, or have even been "tricky bastards" - why would you then rush out to reward them for that with $4000 on a new camera?

Just in case anyone missed it here is the hack methodology in full: https://www.eoshd.com/news/this-is-my-canon-eos-r5-recording-8k-video-50-minutes-straight-until-empty-battery-video-evidence/ Here’s what I did during the 50 minutes 8K test: 00:00 – Power on the EOS R5 normal from cold 01:00 – Remove battery card door, camera powers down but power switch remains in “on” position 01:30 – Insert small screw in the battery door sensor as pictured below. Camera turns back on. 02:00 – Set video mode to DCI 8K resolution (IPB codec) to SD card. 02:10 – Hit record 17:00 – Roll to approximately 17 minutes (“overheat” warning icon will be flashing) 17:05 – At this point pull battery during recording 17:15 – With battery disconnected remove SD card and put freshly formatted SD card in the slot instead 17:20 – Push battery back in and power will return, overheat warning is gone and timer is reset 35:00 – Record for another 17 minutes! 50:00 – End of test I could go until the battery died, basically.

It has yet to be proven that 8K RAW goes indefinitely, but yes it is very impressive hardware. There may be thermal throttling or lock-ups somewhere during long sessions, we don't know - but what is now proven without a shadow of a doubt is how artificial the 15 minute limit is and how it counts down on a timer rather than a high maximum temperature cut off point. My opinion gets stronger every day that all this is about segmenting it from the Cinema EOS cameras. But we all know this is a stupid business decision, because most Cinema EOS camera owners wanted to buy an EOS R5 as a b-cam, second body, third body, handheld rig, you name it. In my opinion Canon seems to want to sell every professional shooter a minimum of 2 very expensive cameras for the same shoot - one single hybrid camera at $4000 plus very expensive high margin optics is not enough it seems. Shoot stills? Buy EOS R5. Shoot video? Buy C500 Mark II. Shoot both. Buy both. Yup it is terrible for us who just want to buy the EOS R5 for it's amazing hardware and cinematic images. We're always the one to get screwed it seems. This is why Canon, in my opinion, has been losing video users for years. It is faulty thinking, throughout the company. I don't know which part of Canon is most to blame - USA or Japan? Both? EOS or Cinema? Maybe both? Or do the EOS guys secretly really dislike the politics that the Cinema business has brought to the company and the restrictions it has placed on their products and all the stupid segmentation? Either way, they must change. I am up to 1 hour of 8K H.265 which is very special from a 45MP full frame sensor. It makes it even more frustrating that Canon has turned it into a lemon then! If Canon chose to lie to their customers about limitations on a $700 consumer camera that was boring and unexciting, the passion wouldn't quite be as strong to uncover the truth and fix it... That it is a very expensive flagship camera and the first of its kind in the world, makes it a hugely emotional topic for me & you, and rightly so.
