WE HAVE DONE AN UPDATED OVERHEATING TEST WITH AIRFLOW, CHECK IT OUT HERE: ua-cam.com/video/NO3X1sqnQIQ/v-deo.html PLEASE NOTE THAT THE THREE ACTION CAMERAS WERE PURCHASED IN THE UK AND HAVE DIFFERENT TEMP REGULATIONS TO OTHER PARTS OF THE WORLD. Also, For anyone wondering why the Insta360 ONE RS shows a different time on the back to that being reported, this is because the Insta360 splits the video file into sections and restarts the timer/timings for each clip saved. Yep, I agree, its stupid.
@@DustyFingersRC Yeah we have EU rules on temp. Not sure exactly what it is, but the device cannot go above a set temp. If you have the device mounted to something with airflow going over it, then it is totally fine.
You do realise that 20mins for 4k 60fps is the best you are going to get out of any action camera. I have the dji action 4 and it is incredible and certainly better than any othe action camera on the market. It overheats less and has less bugs than any other camera. You have to realise these cameras are very small and no camera in their form factor is not going to overheat its just not possible.
@@silverpro8356 And I hope you do realize that this is the ONLY video out there so far that is willing to say the Action 4 overheats. I've heard most reviewers say it doesn't.
Every action camera will overheat on 4k 30fps its just the nature of having something so compact and small. I know alot of these youtubes are sellouts and don't tell the truth about products also but the action 4 is a great camera. @@gayshrink3190
Yes this is the only video I saw that showed finally the truth, I bought action 4 but will be returning this now, as I was filming in a more hot weather and had it overheating after only 10- 13 min at 4k 60 fps, and this make it useless. Iphone 13 pro max holded for 1h on 4k 60 fps and was still going, I had to stop the test because it was more than enough, but could do way more. Iphone pro max on gimbal is the best camera so far for 4k 60 fps, unless you go for dslr and bigger gimbals. Its a shame the camera looks good and the format is so light but its so limited. They should make a bigger version with better and more cooling, would buy it straight away.
Well, guys... Even though I said I won't be buying this camera I bought it anyway. My particular camera is AWESOME in terms of overheating. At 4k60 it died after 80 minutes (the battery died). Being plugged at 4k60 it overheated and switched off after 105 minutes! At 4k25 I cannot make it overheat but it writes something about a slow memery card (which is not) after 2 hours of recording and then stops recording (you can resume immediately). I use default settings and my camera is straight out of China. I know Europe has regulations that if the camera reaches certain temperature it must switch off. Looks like USA and European versions will have these issues. I had GoPro and Sony ZV-E10 before and this camera is better than both of them in its ability not to overheat.
Tried my OA4 in full sunlight today and it shut down because overheating after a few minutes. Started at 4K 60 fps, then 30fps, then went to 1080p 60 and 30 fps. With the last settings it was usable but still shut down. very annoying. No, wind, full sun and 28°C... I have never had that issue with my OA1. U guess I will have to make a little sunscreen over it, or wrap it in a white packaging... Anybody any sollution or the same problem ?
Thanks for doing this. I think for a brand-new camera, the A4 stands up well. Given the time in production and the marketplace, GoPro has had a lot of time to fix the issues with firmware, if that's the issue. If it's a hardware issue, that's a lot more concerning. Of course, we don't know whether the A4 has hardware or firmware issues, but their record on fixing issues is good; recall the focussing issues with the A3. I would hope that they'll have plans to introduce defect fixes and features that didn't make it to the camera by the release date. I expect the dates to be controlled by just about everyone other than the developers, like finance and marketing, for example. Thanks again; straight to the point, and no patronising. You let us make up our minds, and ask for our opinions. That's not the case with every reviewer.
The A4 is just a slightly improved A3 with a slightly bigger and focused lens. So it's actually a shame it took them 1 year to solve the A3 problems trying squeeze out customers by just putting a "4" on it's case.
I broke down and bought a 4, The last 2 times I tried using it outside, it overheated on me after 25 minutes while in 4k 60fps. I use these cams to record baseball games, and the Osmo 3 not once did it overheat. These are 2hr games straight that I record.
I don't like that these cameras overheat that fast. On the other hand, I don't have an overheat problem with DJI Osmo Action 3 when I use it during bicycling, even in a scorching summer day, so moving air around them helps a lot.
Great Video! But how do you think does 2.7k50 compare to your three teste resolution/framerates? As long as 4k25? Or between 4k25 and 4k60? I need horizon locking and 50fps, so i need to shoot 2.7k50 but my Action 2 rarely lasts more than 15-20 minutes
Its an action camera, you need to move around to let the wind to cool down the temperature. So dont have to worry 😊. I used over an hour and its fine and no overheat.
i tested in a coffee shop the temp is around 20C set it 4K 120, dji mimo for viewing at 56 min of recording got message on the screen overheating and display will be turned off, display turned off but still recording, performed better than your test result so happy with my result
This is the neat test, review on the web. The most important test also. Go Pro failure is common after a few often less than a year, problems.arise fro. overheating I think. Looks like the Dji has the beat overall score in these tests.
Action cams sitting on a table, indoors, static... it's not exactly their natural habitat. Also, they're meant to be used on a mount which exposes the bottom to airflow. Cameras dissipate heat through the chassis. Sitting them on a table is blocking a significant percentage of their surface area. Tests like these are a bit like blocking 25% of a car's radiator and then redlining it while stationary on a hot day. By all means, you can do that, but it's not how most people use their cars.
I just purchased the DJI. I shoot in a hot environment and GoPro overheats in a few short minutes. It doesn’t shut down, the batteries just expand or explode! It may be slightly better video quality but absolutely useless to me if batteries explode in a matter of minutes
i recorded on action 3 for 8 hours continuously , and i just kept replacing batteries and memory cards, never overhearting at 4k 30FPS. KING of heat!! Action 4 is trash. Keep in mind the action 3 was indoor in a hot environment. filled with 500+ ppl. lots of heat with little to no air circulation.
the saddest thing for me is that I waited so many years to replace my x3000 and bought a gopro, and now I have to save up for another one, because I feel that if I wanted to sell hero 11, it would pay off on average, and it's better to leave it for one more season despite its flaws
Wish they made a better design like maybe if they made the whole surrounding edge of the case to act as a efficient heat sink and probably on top make it slightly bigger so that it can dispate heat better
Thanks for doing this test I regret that I didn't find it before buying my insta360 one rs. Mine overheats after 15 min on 4k 60 and then I have to wait 10 min to be able to record another 15 min. I don't understand the meaning of advertising about the outstanding 4k capacity if you are unable to use on real conditions. The insta360 one rs is unstable and unreliable it doesn't worth the money.
Two months ago, I bought an Osmo Action 3, since the beginning it had a focus issue. I took it to the authorized assistance, after inspection by the technician, he found that it had a focus issue, I left it under warranty, after two weeks they returned the camera without fixing it and did not give me another one. Advice, do not buy DJI brand camera, you will lose your money. Thanks
Well clearly if overheating is a concern, the DJI is the way to go. Yes the GoPro can shoot at 5k but who cares? Does anyone even use 5k for commercial consumption? Maybe it’s just me but give me a 4K 120fps option over 5k any day. Heck give me 1080p if we’re really being practical.
Sucks - had to use my iPhone to finish recording video because osmo action 4 over heated Same thing happens with action 3 Guess it is an action camera, most action shots are short - can’t imagine falling from the sky and jumping from the plane for an hour But if I did , would probably use the iPhone - it would last all day Forget about taking video on a hot day… Maybe they will fix this with action 5
If you're from the European union the temp regulations governs how hot the camera is allowed to be. Took my a3 to Indonesia and overheated with 1080p 25fps in 10 mins. I know that ambient air temp is obviously different but 10 mins!! Got home and found a crackconfig file from UA-cam installed on SD card and now can record 4k 100fps for the entire duration of the battery. Ambient temp was 29c😊
@@TheCameraManReviews dont have AC in the car, so basically the air going to it, is merely 40degrees celsious. I triede lowering the resolution to 2.7k, it changed the recording to about 15-20 minutes.. but unfortunately, the 1st osmo action is just grinding through, even in 4k 60hz :-)
Another issue with the cameras running hot is that they cook the battery, I had to use pliers to remove the battery from my hero 10 because it was so puffed out, battery was garbage after that, even plugged into the computer via USB it gets so god damn hot that it's best to remove the battery before... Pathetic...
We just ran an overheating test on the DJI Action 4 in a room (approx. 21°C) at 4K50/HB settings. The result is a drained battery with a video 95 minutes long. What are we doing wrong? 😲
Absolutely not acceptable, especially in 68f. All of these cameras should record the full battery at the highest settings they have, especially at this price point...
The gopro will just overheat in standby. Out in the sun. The moment comes when you say, gopro start recording. It wakes up only to display the overheat warning. Frustrating.
It's actually alarming that actioncams overheat this quickly and that we find it "normal"... Why buying a $350 action cam while it can't record action longer then 15 min? 😅 They should change the name from "actioncam" to "TikTokcam"
