Its quite clear that canon engineeres or managers are aware how to build it like this.

I haven't even started watching this video and had the same thought of transporting the heat through the bottom.

Whatever made canon made it like this, was on purpose.

Either the concentrated on picture for the most time and realized to late and it would have required rebuilding core parts and not getting it out in time or they will bring out a camera/pro version to this with unlimited 8k recording and with a higher price.

The assumption that a hobby engineer can solve this issue while canon can't, is not realistic.

Based alone on the original firmware approach, i would argue that time or priority was the issue.

Yeah, no way they overlooked something like that. I had my Sony α6100 overheat within 20 minutes on mere 1080p video when the ambient temperature was at least 45°C. When these things run hot, it’s easy to feel where the hottest areas of the body are, and attaching a heatsink is obvious, and at that time, dumping heat to the tripod mount was the first thing that occurred to me when I contemplated how I might do it.

The flip side of this is that Sony (finally) made an APS-C mirrorless, in the α6600, which has a recording time that's only limited by power or storage.

So it was never impossible, and it isn't just a Nerf to segment customers into the cinema bracket. It's just an area where they're willing to compromise.

Without IBIS, the αN < 6500s aren't great for many video applications, they're photo cameras which can also take some video. I suspect that Sony just didn't realize the degree to which the YouTube generation would be using their entry-level mirrorless systems for extensive video. Consider that it took them a generation to make flip screens standard, and that they bumped the battery size and ability to record indefinitely on (only) the model which has IBIS: that's a nudge, saying "If you want to record a lot of video, the α6600 is the model you want".

It was the α6000, α6300 and α6500 that were time-limited, because they generated more heat in their video encoding. The newer α6100, α6400 and α6600 don’t run so hot, using a newer and better chip for the encoding. You’re wrong about the ability to record indefinitely: this is not specific to the α6600; all three of the newer generation get it. I’m recording 100 minute videos weekly on my α6100 with no sweat now (plugged in by USB, otherwise the battery will be down to 5–10% by this time—with the camera fixed in place for these recordings I also don’t care about image stabilisation, whether in-lens or in-body), it was only having trouble in the middle of summer when the ambient temperature was at least 45°C.

[samatman]

Alright, good to know.

I think that's more evidence that the overheating problem wasn't a deliberate attempt to segment customers into the cinema bracket, but rather something Sony didn't realize would be such a problem, because who is going to want to film 100 minutes on their photo camera? Practically everyone as it turns out.

Yeah, they could have and should have added better heat dissipation: but they can and should make (much) better software as well, and don't, because... it's Sony.

It doesn't have to be the engineers who overlooked it, I am sure there were a lot of great cooling solutions thought of once the overheating issues were discovered.

However, the management did overlook it. Now the machine overheats and requires hours of cooling down to shoot continuously for more than 20-25 minutes. Is that an acceptable amount considering any kind of film work?

[Rillen]

Its not build as a film camera and its not a film camera. Its a picture camera.

The market segmentation is totally different for that.

I would still buy it. I have a Canon 80d and 90d and i rarely do any video recording at all. why? Because just a recording ready body doesn't give you good video. You need audio equipment etc. and 8k video is huge like wtf huge.
