    FAQs:
    1. Yes, I also tested with a dummy battery. So did Philip Bloom. Results still varied wildly.
    2. Yes, I practiced proper heat-control methods. E.g. screen out, threshold set to HIGH, etc.
    3. Everything was identical. Same battery, same cord, same card, same placement, same target, everything that I could control was the same. Exactly the same.
    4. For those that misunderstood the conclusion: I'm merely suggesting that less confidence be placed in overheating test results as we don't know enough to explain what's causing the shutdowns. I thought it was ambient temp previously, but clearly something else is at play. And if it's more than just ambient temperature, a controlled heat chamber might still be insufficient to provide meaningful data since we know too little about what actually triggers an overheating shutdown.

      Is it possible that the sensors are just cheap and unreliable? (The cameras obviously have a temp. sensor within to tell them WHEN to turn off...) - My car thermometer, for example, will tell us it's 40 degrees when it's actually 31... and then on other days it says 20 degrees when it's 25.

If the embedded software doesn't handle those edge cases proprely, it may consider it as a high temperature and decide to shutdown. Those glitches are random and could explain why your results are random.

    I think the reason the cameras are overheating at variable durations is because the battery is charging/discharging while connected via USB. The test you showed at 4K24 that ran for 2h 19m was the best result probably because the battery was just discharging the whole time. You should try re-running a few tests using a dummy battery as the power source. I'll bet you'll see a dramatic improvement in run time.

    I've seen the same variance in my experience with my A7IV and A7S2 (not just in webcam mode, this also applies while recording long takes/streaming using the HDMI output).
    In the end I've just stuck to a couple of best practices, and since then I've never had any overheating issues.
    - Even the smallest bit of moving air will make a gigantic difference vs completely static air. Even a small and slow fan near the camera, where you can barely feel any air movement, will make a big difference in my experience.
    - Opening up / flipping out the screen whenever possible so air can move along the back instead of trapping the heat.
    - The biggest contributor for me: using a dummy battery. The battery is often a large contributor to the generated heat, so this moves that heat to outside the camera and replaces it with a cold part that can even soak up some more heat from nearby components instead (or if your camera allows it, you could power it through usb and leave the battery door open). On top of the heat benefit you can then also use much larger external batteries or AC power for infinite runtime.

    • @LennertK
      @LennertK 7 місяців тому

      @@Digitalfiendscom I don't really remember what brand mine are, I just check before first use if the pins correspond to the right ones when adapting straight from a larger NP-F battery (voltage on those are the same so no conversion needed), or that the voltage is correct when using AC or any conversion.
      I don't think there's anything wrong with the unit you were looking at though. If the "nominal voltage" of the battery for your camera is reported to be 7.2V, it will range from 8.4V (fully charged) to somewhere slightly above 6V (empty). If the dummy battery provides 8.4V, your camera will show that the battery is 100% charged.
      The way I calculate those values: a standard lithium cell goes from around 4.2V to around 3V with a nominal voltage of around 3.6V (different cells can have slightly different specs, like 3.7V nominal or 4.3V max). If a battery has multiple cells in series, every value will be a multiple of that. In this case the nominal voltage of the battery is reported to be 7.2V, which is 2 * 3.6V meaning two cells in series. That is why each value is doubled (thus the range is 6V to 8.4V).

He showed what "-10° to 40°C - no overheating" means and that Panasonic makes sure that cameras with this specification meet the mark. After almost an hour it was obvious that the camera could go on but Sean ended the stream a bit earlier than usual.

    Theory: the temp sensors that trigger the overheat protection aren't really measuring the overall "warmth" of the camera, they are instead measuring one, or more likely several, critical components prone to overheating, i.e. processing chips. These can run indefinitely (for some cameras) when the only thing the camera is doing is streaming the video over USB, but if one or two other tasks start up in the background, it will cause a chip to exceed the thermal dissipation it can handle, and it will quickly trigger the protection. So the discrepancy in your tests may then have less to do with the ambient temp of the room than some other function of the camera, or a buggy interaction with the host computer. For example, if the camera is connected to wireless (I know some modern cameras are starting to do this, not sure about the ones you tested) it might be phoning home, looking for updates, etc. Or the algorithm that monitors the locally available wireless networks or nearby bluetooth devices might have some associated periodic task or whatever. Or the camera might just have some unrelated internal periodic task that triggers at unpredictable times. Or something happens on the host computer that triggers an invisible background task reaction in the camera, etc. It certainly sounds like something a firmware update could address. Others have also mentioned that battery charging/discharging creates warmth, and although I assume these cameras were all fully charged during these tests and running on wall power, that doesn't mean there isn't some battery-related stuff happening in the background that might generate warmth or trigger tasks. And one final shot in the dark: very slight/imperceptible variation in how a camera is latched into a tripod might dramatically alter how much thermal coupling between the camera and tripod occurs. So if you had the stomach for more tests, I would try running the cameras with no battery installed, in "airplane mode" if such a thing exists for cameras, with no memory card installed, streaming to a minimal linux installation, and not mounted to anything, just to rule out as much stuff as possible, and see if the results become more consistent. One can also be paranoid and wonder if manufacturers have started detecting when overheat testing is underway (e.g. static unchanging scene, minimal audio fluctuations) in order to push things a bit farther than they otherwise would.

But hey, they ALL get hot at some point, yes, they do, but it seems to actually matters if it STARTS hot in the first place... For some reason, if it starts off hot, it will, given the same environment, perform better than if it starts cold. I noticed the same thing with my laptop.

    The charging factor might play some role but it seems this is a reflection of some other random process running within the camera that is competing for CPU with this streaming / mirroring process. If that process is running at the time you start the live stream, the two compete for CPU and keep the temp elevated until it shuts down. It could be a function of some other menu mode that was invoked just prior to starting the stream. If the physical camera CAN run for 8 hours, the core process and hardware support it clearly CAN operate efficiently without thermal problems. The "camera OS" has some other problem the maker needs to fix.

    My theory is something something happening with heat sensors, and the sensors might be similar if not the same in all those models. Remember Canon R5 situation, when it "overheated" upon release pretty quickly but after firmware update they kind of fixed it? So my guess is the heat sensors could potentially go crazy because of some small variables, so in the reality we can't truthfully rely on those. I also really interested in infrared temp check of the same camera when it's running for 8 hours while being ok, and "overheating" for like 30 minutes. If there's no change in 'internal' temp, it's a major issue since the longevity of the cameras can potentially drastically harm because of those potentially false overheating indicators.

    Ambient temperature isn’t the only issue. Being in direct sun can cause a camera to overheat quickly too. My former Sony A1 would overheat in minutes in direct sun, but draping a white towel over it would extend recording time substantially. Now some cameras that are properly engineered to handle heat don’t have that issue, even in direct sunlight.

    I've had to do my fair share of overheating tests in the past - though my goal was to simply answer "can this camera go longer than 4 hours connected to a Cam Link" - but even then you're right, ambent temperatures can play a big role. What I'd be curious about though is where your thermometer is in your testing room because in my office my computer area will be the hotspot so depending on how much my laptop wants to be a radiator at that time will cause that corner of the room to go up in temp by a whole lot while the overall room temp might experience a smaller change in degrees. A solution to that is to keep the camera far away from the computer in testing so IDK if that's your type of setup or not.
    A big factor that most Cam Link users run into who experience overheating is they will plug in a USB cable for power while keeping the normal battery in. This is a big generator of heat and even when just passing through the HDMI live view to a Cam Link - the heat generated from the battery can be enough to cause overheating. Meanwhile dummy batteries don't warm up like this so you get a marked improvement in performance. So even for Sony's webcam mode I would suggest using a dummy battery just as a safeguard. It's also just convenient to not have to worry about any slow battery drain from the usage either - dummy batteries never die.
    Also, not to shill here - but I think that if the user described at the end, if the live streaming feature is really the determining factor between 2 models (Let's say I'm deciding between ZV-E1 vs. A7CR) rather than spend another $1k for the extra time in webcam mode, it'd be more cost effective to just go for the ZV-E1 and just use a Cam Link to handle the webcam aspect of it (IMO)

    I saw reviews of various Sony cameras and overheating issues. It significantly impacted my decision to get a Sony FX3 as I do primarily video work of live events and can’t call a stop for the camera to cool down. The Sony ZV-E1, FX30, and the A7 series were all considered, all had vague reports of overheating. I went with the safe, although more expensive route. It also means I still need to pickup an A7 of some sort for stills since I’m now investing in Sony glass. Overall I’m happy with the FX3, just ranting a bit.😀
    I wish there were consistent/repeatable tests to feel out the limits. Can it do 2 hours without overheating in a typical indoor space? Does it only have issues in higher temp environments? What about in direct sunlight? I appreciate the rant on this subject. It needs more attention. Thank you

    The only thing I can recommend is to do more tests and plot them on a graph. I'd also do tests with the temperature maybe at 19C, as well as 25C. It may just be that it's on the fringe of overheating, but because the camera temp + room temp can fluctuate, including possible drafts, the point of overheating is basically tilting on the edge of a cliff.
    When we think about the derivative (think acceleration, it is the derivative of velocity) of heat, something coming to a temperature is logarithmic. It will *start* heating up quickly, but as it approaches it's target temperature, it takes much longer to transition. Do *not* think of a heater or oven. Think of a computer coming to temp under a load test, or an object sitting in a room and coming to temperature.
    It may be that the overheating point that is set in the camera's firmware is just barely on the edge of it's max physical/actual temperature when in that mode, so little fluctuations can cause it to randomly hit that temperature limit.
    Besides that, there could be a dynamic nature to whatever encoding/processing it is doing. It could depend on what it is recording. Similar to how CRF rate control can dynamically change the bitrate based on complexity, and the encoder requires more processing when it is a complex/fast scene.

    camera overheating tests are dumb when we're talking about the units sent to the youtubers. The ones sold to the general folk tend to overheat MUCH faster than what the youtubers report.
    Here's some of my finds:
    Lens choice makes a HUGE difference on overheating times. First i found that BIG LENSES dissipate a ton of heat, I tested 2 A7IV 4k60 and switched between 35 prime and 35-150 tamron, the tamron one lasted 1h45 and the prime lasted 55min, then switched lens, cooled and put new batteries in and once again, the camera that overheated earlier with 35mm , now lasted 1h44 with the tamron, and the other lasted 58min with the 35mm prime. which confirms the lens making a big difference.
    The whole "no1 needs to film 1 hour 4k60" is a really bad argument on sony, as sonys overheat as fast on standby. so if 4k60 overheats in 20min on a zv-e1 for example , it will also overheat if you record 1min, standby 3min, record 5min, standby 4 min and record 6-7 min more (keeping the screen on).
    I also seen a guy who tested sony ZV-V1 where if you overheat, wait 5 min then record again, will go LONGER than if you just do a single take, meaning theres some software trickery involved as well.
    Essentially theres a trigger if the INITIAL temperature is higher, it lasts longer than starting from freezing cold. ( I assume the overheat trigger might be a formula OVER initial temperature delta, and not absolute temperature)

    All those Sony cameras have a config setting: MENU>Setup>Power Setting Option>Auto Power OFF Temp>High/Standard. Sony says if it's not set to HIGH, the camera "may not achieve continuous recording in most formats". Sony gives a thermal shutdown spec in minutes for each camera when recording at HD and 4k, both 60 fps, with the shutdown setting at HIGH and STANDARD. They also give separate numbers for 25C (77F) and 40C (104F) ambient temps. Sony says the LCD panel should be pulled out, which helps with cooling. For my A7SIII, the spec is 120 min at HD and 90 min at 25C, yet I've done probably 100 five-to-eight hour Zoom calls (admittedly at 1080p/30), and it has never shut down. For those, my camera used HDMI output and USB-C external power and internal battery. If you Google 'Sony "auto power off temp" ' it will show you the Sony specs. These specs are for recording, not just feeding a UVC or HDMI output, so there's a possible difference there.

    All this tells us is that, unfortunately, most Sony cameras (as well as Canon and Nikon, to be fair) are simply unreliable for consistent video recording/streaming. It is clearly a manufacturing flaw, but the camera cabal has conditioned us to accept it as a 'feature' :D
    Long live Panasonic!

    People flamed Dan Watson years ago for his overheating tests in Florida, but he had a point. We shot a wedding last Summer in Charlotte, NC and the A7SIII overheated outdoors shooting 4K24p while in outdoors during the ceremony. No warning or anything. We had the FX6 running as well, which saved the ceremony footage. Sony has improved tremendously over the last 8 years, but there are still concerns in some situations.

    I do a 2 hour livestream every week with a Fuji X-S10 (different channel). Gives me a warning after less than an hour but works fine for the full 2 hours, except in the summer when I have to turn the lcd display off otherwise it powers down before the 2 hours is up.

    I don’t know how you’re getting such short times on the A7C R. I recorded for 12 hours USB 4K30 streaming until the battery slowly died. Then I, without waiting, put another battery in and got 13 hours.

    I'm wondering if the speed of your connection to whatever you're streaming could be a factor. Like if there were some additional fraction of a second delay down stream to the computer could that be causing the cameras bot buffer the data leaving the camera? I've had cameras that in the past have overheated when using slow SD cards that ran fine for hours when using fast SD cards and my assumption was that the extra buffering between the image generation and the writing to the card was resulting in the camera's processors running harder/getting warmer. You're talking about live streaming so in a perfect would there really shouldn't be any buffering in the camera, but in reality there is going to be some bottle neck (miliseconds) between the camera and the computer and then between the computer and the internet. I'm not an expert but it's conceivable (although I don't see why it would work this way really) a bottle neck on your internet connection could translate all the way back up stream to the camera's processors.

    There’s another video of a user that did kind of crack the results. Sony cameras actually need to “warm up” before doing any long for content.
    So running it for 10-20min then shutting off. Then you’re able to do a long stream. Kind of matches your results with the times alternating.

    Most people do not notice one thing:
    Electronic stuff like Mainboards, Smartphones, Tablets, Notebooks and cam fail mostly due to HEAT.
    Failing elcos, soldering, dead batteries etc. These are all things that will fail earlier when exposed to HEAT. If one does not believe me, just check after sales figures...
    I own the GH6 and a X-H2s and had both NEVER set to HIGH TEMP! This is not a "magical" setting that reduces the risc! 🙂

    I always use HDMI out for video at 4k60fps and USB for charging. Never had the A7IV overheat for stream (up to 8 hours) but know someone who has.
    I tried the ZV-E1 and it overheated twice within 12 minutes of a stream.

    tbh i had my a7iv overhit on 24fps, shooting a 2h show. i was running the camera using a power bank plug in . the overhit sign came in within 5-10min of use, i was making air to stop the overhit, and have done that for 2h lol . camera was set to high . that was pretty ridiculous

    • @Ra-Hul-K
      @Ra-Hul-K 7 місяців тому

      the power bank recharging the battery as it is getting drained is also contributing to your overheating issue.. have you every used a phone while it is plugged in and charging? it overheats faster.. "i was making air" maybe one of those small, silent pc fans would be a better option to move air around the camera.. or one of those clip-on fans from Ulanzi.. & while you are at it consider using a dummy battery instead, thereby eliminating a potential contributor to internal temps.. and maybe leave that battery door open too (I'm assuming that the camera stays on a tripod)

    I used A7RIV and later A1 for home office conferences but I was using an HDMI cable connected to a PCIe capture card running 4k60, rather than internally encoded through USB. Some conferences lasted for nearly the full day, skipping 2 hours during the lunch time. Neither camera has ever overheated. I always have the screen stretched out for better cooling.
