Video Hummus

Thank you those were good reads!

This is dead on. And people would have paid $1000 extra for the this “R5 C” just because it’s a Canon and had 8K RAW and 4K120p with the autofocus and clog3.

Brandon Li’s work. He is super pragmatic. Says the camera is an upgrade in almost every way for him (he is not a stills shooter). He didn’t use a PP either. I think the main highlight in this video though is the autofocus. It’s amazing!

They’ve put themselves in a box. I doubt it having better specs than S1 if it’s suppose to be entry level. FF 4K60p is a stretch unless they also add it via firmware to S1. Affordable L mount Lenses are still limited. They just released a “vlogging” camera that nobody really likes or wants. I have no clue why they are releasing a new model. Unless it’s a GX style FF camera, which would be appealing to some.

This could very easily turn into another G100 level blunder 🤦‍♂️

Something like this: if (HDMI_SIGNAL_OUT && (LCD_SCR_STATUS == OFF)) { CRIPPLE = false; { else{ CRIPPLE = true; }

Please inform these people immediately. They have been wasting their time! https://en.m.wikipedia.org/wiki/Academy_Color_Encoding_System

Meanwhile, Andrew and many others are testing the camera to see what the real boundaries are. Heard of Magic Lantern? Lots of cameras capable of much more than what Canon chose to give you.

Yes, I don’t get all these color purists. We aren’t shooting 8-bit h264 anymore. Once you go above 8-bit color codec, excluding doing crazy color changes, you can pretty much match any camera you want with any other camera within a certain margin of error. Lets not forget of course that our eyes perceive color totally differently! Even further, individuals color “pleasing-ness” is such a deep rabbit hole as to make it impossible to say any camera has “the best color.” That leaves DR, highlight roll of, compression artifacts, and the mystical motion cadence as the biggest differentiators. You can tweak the highlight roll off a tiny bit, but not much. That is mostly down to how good the sensor is, ie 16-bit linear off an ARRI versus 12-bit or 14-bit log off of something like this A7Siii. And finally, if it’s not your job to get the best image you can on a multi-tens of millions of dollars movie and you are focusing so much on the colors out of your camera...you are optimizing the wrong thing my friend.

We can safety rule out the sensor heat as being the main culprit if people are able to record 4KHQ externally for hours on end. It is either something going on with the CFExpress cards getting to hot or some kind of timer that is started when they are inserted. The fact that the camera power cycles when the memory or battery doors open may be a hint that that may be the case. Please keep testing @Andrew Reid and @mechanicalEYE very helpful for people.

Yet it takes 1 hours of sitting with sensor exposed and battery out and card slot open to get 5 more minutes. Some serious bugs there.

We need to establish: using direct temperature readings as close to the cpu as possible, a graph comparing this direct temp reading to the EXIF temperature. This will tell us wether the EXIF temp is a reliable indicator. we need to chill the camera to the advertised coldest operating temperature and then turn it on to take a picture and see what the EXIF temp is reporting. It should be lower than what it reports at a cold start at 24C. If it isn’t...then something funky is going on. A graph of temperatures running in 4KHQ to shutdown and 8K to shutdown. If they aren’t pretty close to being the same. Something funky is going on. A graph of temperatures running in the 4K line-skipped mode compared to the the 4KHQ mode. If the graphs are the same. Something funky is going on.

I still think we need more tests performed well before we can conclusively say the timers and overheating warnings are BS.

You’re probably right. I was hoping and still hoping we can finally get a useable Canon hybrid camera out of this. I’m doubtful.

Funny how the laws of thermodynamics and physics work, eh? So many awesome things and cool technology we have today yet somehow those laws and physics are sucked into a black hole around the R5.... Its not the weather sealing insulating the camera, it isn’t the lack of heatpipe or heatsink to cool components, it isn’t the scorching hot ambient temperatures (or the freezing ones at that!), no its the classic, completely bizarre, canon cripple hammer coming down hard. I think they might be open to litigation. The overheating icon on the screen, the increasing evidence that the overheating issue is bogus, the complete lack or care to mitigate heat inside the camera. They have some explaining to do.

Yes. Someone needs to take the bloody back panel off without disconnecting the screen and be able to power the camera on and record 8K. Take that shit into a walk-in freezer at -4C or 0C with a fan and blow freezing temps over the back circuit board...if it overheats or doesn’t slow down any of the timers than the timers are a closed loop and temperatures do not effect them! Meaning, it’s all software regulated. If the internals being exposed to freezing temperatures doesn’t improve the “overheating” then Tilta’s stupid cooling kit is beyond ridiculous. The fact that there has been multiple independent test of the camera overheating roughly the same time in cold, hot, and extremely hot conditions tells me that the outside ambient temperature has nothing to do with the cool down timers at all. Period. Leave it in a fridge for 1 hour...I bet you it will tell you 5 mins of 8K left as well. Make sure to put a beer in there as well so you can drink it after your realize what your 4400 euros got you.

There is the possibility they will piss off their cinema customers. But I would think their cinema customers would be first in line to buy this camera if it did 4KHQ with a much shorter “recovery” time, or no recover time at all. I think the 4KHQ mode should be unlimited. It’s pretty blatantly obvious it is because magically plugging in a HDMI cable makes it possible.

Poor Tilta their product was a lie too!

Or they could have said something like this: ”The R5 embodies everything photographers loved in the Canon 5D series. It is a sign of our commitment to continue this excellence into our mirrorless RF camera line. Although video was not a focus of the R5, we still put in some exciting video features for light video workflows. Stay tuned for more exciting products in our EOS and Cinema EOS family of products.” I realize it may have sold less R5’s to video originated people that were excited for it. But what is worst? Giving them an utter turd that just pisses them off and damages their brand prestige. Very, very stupid. But maybe I’m too idealistic. People these days have short attention spans and myopic views (I’m not faultless). I’m not sure what they are going to do. If they someone increase the performance drastically they indirectly admitted it was all a scam and they were deceptive about it. If they do nothing they risk alienating and losing customers who will just want to get their 4K120p camera and will buy Sony. If they say they tweaked it and got a bit more performance...it won’t be enough.

Yes I agree. But how? I’m not sure you can take off the back panel and expose the PCB and keep everything working. You would need to take temperature readings from inside.

Yeah there is growing evidence this overheating scheme is entirely bullshit. Why not just be honest with people? Have clear limits to the recording modes. The only possible explanation is that the temperature being reported in EXIF are of PCB temperatures and not what the sensor is at. But then again, we have people with thermal cameras saying the sensor never gets above 60C....

I wonder if this strange battery door “feature” is to avoid the battery being pulled? What other Canon camera has ever done this? Any camera at all? And how would you use a dummy battery for DC power?

This is incredibly interesting. Would be nice to have a third party try this out and see if the results are replicated. I think this next firmware is going to “fix” that EXIF temperature reporting. Why the fuck did they implement this absurd recovery timer. It’s beyond the realm of defense for being a “conservative” feature to protect the camera from overheating. It’s straight up bullshit, it seems. Great stuff.

More evidence that makes me think the outside temperature has no baring at all on the overheating.

This is a good angle to try. Assuming it’s a software limit and the camera doesn’t detect and do a emergency power down write which it may do to protect data being written to card (ie, closing out the file being recorded so at least the movie file isn’t corrupted).
