Yes, but with this caveat - "EU area recording time will be lower than other areas, due to European policy requirements, the temperature threshold cannot be set as also mentioned in the last part of the response above."

Hello there. Measured with the touchscreen turned off and Wi-Fi disabled, in a windless environment at a room temperature of 25 ℃, when recording 4K videos at 60 fps, the Pocket 3's operating time can be up to 118 minutes until the battery is depleted. When recording 1080p videos at 24 fps, its operating time can be up to 166 minutes until the battery is depleted.

The max video specification supported by Osmo Pocket 3 is 4K at 120 fps. When recording 4K videos at 120 fps, the operating time of the general version is about 17 minutes (with over-temperature protection enabled), while that of the EU version is 12 minutes (with over-temperature protection enabled). Have a great day ahead."

“Can be up to 118”, that reads between 0 and 118 minutes it’s not specific.

Yes depending of The battery.

Depending on battery but external factors also play a part. Would you expect it to last 118 minutes filming  in the middle of a desert for example?! I take all these numbers with a huge pinch of salt. You need to perform your own tests. DJI tests are under strictly controlled lab conditions in order to squeeze the most they possibly can out of it. There are too many external factors to even consider their numbers to be remotely useful. Guideline, yes. Nothing more.
That’s how I take them anyways.

No but when requirements are met then yes:

"Measured with the touchscreen turned off and Wi-Fi disabled, in a windless environment at a room temperature of 25 ℃, when recording 4K videos at 60 fps".

This is how it is SOLD. In business and in law there are requirements that needs to be fulfilled.

Our outdoor temp is -3 C and it still overheats in there after 23 minutes when using Kingston SD card. I should be OK with that because we are in EU? right.

This is the topic where people are answering to posts without reading anything. I stop commenting here for now. Start was team play now here are just trolling and EU haters with their politics etc. useless comments.

Welcome to forum.

Some people here have some benefits that works in background, they will always troll people if they post an issue. Get used with it, I am for now.
Check how Hallmark activated himself after my post, without mentioning him or other...he felt his guilt and started to scream TROLL, like the thefts that start screaming THIEF when they are caught.

The fact is simple: In Europe some OP3 works and some does not...There are 2 factors that make the difference:
1. The ambient temp when operating it
2. The assembly quality and radiator mount inside OP3.

I must admit I have seen at a friend one unit working with same settings up to 35 minutes in 4K 60 until started Overheat message....after this, was unable to start it for 5 minutes, each start giving in less then 1 minute OVERHEAT message. Only after cooling down a little was able to start again.
The one I have tested (YES, DAVID, is not in my list YET, as that 2 x AIR 3 appeared 2 months after activation, one not even now is shown in list) was overheating fast...Yes, the crack file works, but is pushing the OP3 temp to a very high limit...

As for Mini 3 Pro, between launch and +6 months after, DJI changed thousands, until they applied the method I sent them, to fill the chamber with rubber...Yes, David, was sent by our dev team, after we have dismounted and tested it...So try to slow your horses, as you are a noob in this.

Cheers.

Wow, is it actually overheating with a -3 °C "room" temp (filming outside)?

That means the thermal design is really poor, one could expect with such a low temperature it would never overheat... I'm mind boggled :x

I really don't get it. I shot a walking video outdoors (in EU) at around 9C. 40K50 HLG, limited ISO to 50-800, walked around for almost half an hour at night and in the end I wanted to see how hot it got, and the place which is usually the hottest (right under the gimbal) wasn't even warm!!
But I also had it overheat after not even 20mins doing an indoors static test.  I also did a static test pointed at a TV with the 'heat test' config file and it was very hot after 30mins. Other time I did a static test, pointing it outdoors in the dark and it would run and run >60min, getting just a bit warm. All 4k50 or 4k60. So my feeling is that the content (e.g. bit rate, maybe ISO rate, coz more noise=higher bit rate?) also matters a lot when it comes to the heat generation.

Yes, as H265 codec is using blocks for encryption and P-frames are faster if you get noise (more data), any 10bit format in this environment will have a faster heating of OP3.
Still, as one member here tested also H264, seems that this easier codec is also causing an Overheat, but after a while.
We can conclude that can be any or a part of this:
1. CPU is too underrated, being used at 100% in coding 10bit with a lot of P-frames causes a lot of heat
and/or
2. Heatsink at some units is not properly attached using a very good thermal paste (we all know the difference between a good quality paste like Noctua or Prolima and some grease unknown producer paste).
and/or
3. Flaw in design with heatsink too small
and/or
4. Improper/ not optimized codec (unfortunately this will mean that DJI will upgrade the firmware with less quality in order to easy CPU threshold and keep it cooler).

At this point I recommend to EU members to take a unit in test and return it if they see any warnings in legal period, do not wait for fixes as you never know what will be...

After 1 hour (i never filmed so long) the camera is filming with no issue. Home temp is 23c°
The camera heats but stays under 60c°The red dot is max temp : 59,3c°, blue dot is next to my display, thats why its little bit over 23c°.

So i would think its in an "no-zone" mode.
I just passed 130 minutes filming.

When will be activated, will take the setting by area, if is EU will get the lower temp admittance, as EU laws.

Two solution :

- Activate it in other country (but how ?)

No you should. But this guy spends all his time trying to create hysteria. He has done the same with every single dji product in the last 4 years. He believes they’re all crap yet he continues to buy them or at least some of them. He’s here trolling he’s not interested in trying to give any advice unless it’s useless advice .

You can use the hack fle as it will change the temp limit from EU to Other.
If you tested the unit without activating it and works fine, with that hack file will be ok.
Test in low light, with multiple movements in order to push the encoding to max, 4K 60 fps DLOG....

Well, you could send it to me in Australia and I'll activate it here...  but would I send it back?!  More seriously, the implication in a DJI post that it uses GPS for this purpose was interesting.  Turn that off, if  possible, and it might not realise your EU location.  But "might" is the key word.

Goodnight.  I look foraard to seeing more of your tests tomorrow.

I think the GPS use is just for output tagging. The app can determine location via WiFi geolocation.

Well you could try uninstalling the Mimo app. Getting a fake GPS app from the play store and faking your GPS to the USA. Then reinstalling the Mimo app and activating.

Have a look here https://www.lifewire.com/fake-gps-location-4165524

Might not work, but you have nothing to lose by trying.

It seems that after activating un France (EU), after firmware upgrade, the workaround files is effective for recording in 4K/60fps, i stooped after 70 minutes.

I made a try in SM 4K/120fps, and got an over heat issue very shortly.

I ordered the camera from the official DJI website on the day of release. It came to Poland after two days and was also activated here. A few days later I went on vacation to Turkey, where I tested the camera and had no problems with it. I also have the infamous Action 2. I used Mimo App on both cameras. Action 2 automatically detected a location outside the EU, so I could select High Temperature Threshold, which of course I did. I probably also used Pocket 3 on non-EU settings and today, after returning to the country, I tested it in 4k50 (I don't know why you use 4k60 settings in Europe - the electricity frequency is 50Hz and you should record in the PAL system). Color: D-Log, HEVC codec Ambient temperature is 23 degrees - without airflow in the room. The memory card is Samsung EVO Plus 256GB (MB-MC256KA/EU) U3, V30, A2. There was a cooldown of approximately 30 minutes between each attempt

Non-EU location (I did not turn on the app after returning to Poland):
4K50 - 32:22 minutes until overheating

EU Location (when connected to Mimo app to change location):
4k50 - 31:18 minutes until overheating

As you can see, the results are the same and are within the measurement error. This means that the camera activation location is used when setting the temperature threshold.

Hello,
Tests you've made might help to understand the problem.
I film in 4K/60fps to get high settings, but i agree it ovious to choose 50 fps, normally.

You can use the "workaround file" to bypass over heay limit. It works pretty well, for the moment.

In fact, now its shure that activation of the camera determines heat limits.

Try 4k 100fps and 4k 50fps they should give slightly more recording also turning down screen to 50 % brightness will also help to dissipate some heat.

To be honest I very rarely, if ever, record for more than 5 minutes or so without stopping. I generally capture shorter clips for post production later. I know this is not a solution etc and doesn’t make the situation any better, but does mean for my personal usage the heat is a non-issue.

Still need to test Timelapse and hyperlapse though, since they would of course naturally be much longer, but these are less demanding modes in the first instance.

I tested mine (SanDisk Extreme Pro 256GB) and managed 26mins at 4K/60, with an ambient temperature of 23c. Although that was with screen brightness at 100% too. That far exceeds my typical usage, but even so, I’d like to think my unit could get a lot more, and work as advertised.

Retest at 4K/50 with 50% screen brightness next, exact same shooting position and conditions, resulted in 65 mins before the battery depleted (I didn’t charge it after the first test!). These are my general go-to settings anyways, so seems like this will work for me…….

At this point I’m in 2 minds. I ‘m going to continue to use the camera as normal and see if the heat is an issue with my own day to day usage. If it is I have until the end of Jan to return for a full refund - my fear is that the overheat protection will kick in too soon in the heat of summer etc……

Hi,

Well, the fact our electricity in Europe has a frequency of 50 Hz is not relevant when you want to choose your filming framerate, because first of all, natural light outside is not impacted by this at all and for the rare cases where you'd have some old light bulbs which would "flicker" at 60 fps, just use the anti-flickering integrated system in the settings (I guess its default value is set to "auto") which appears to work pretty well.

At 60 fps, you'll get a smoother footage and I personally like it over 24 or 50 fps.

i found in another post the following:

https://forum.dji.com/forum.php?mod=redirect&goto=findpost&ptid=301054&pid=3172683

"I spoke to DJI Support on the app, told me to reset the camera so I took the SD card out reset to factory settings on the camera and did a very very long time lapse this morning and it worked okay so maybe just a glitch"

Not sure if that has been tested as well by the others in here, next to the "local file solution".


I do own an OP3, but the icon is not added yet by the relevant team. Ticket has been raised about it, just need to wait. Didn't had the time yet to make long video, to experience myself as well.
