Hi,

Just wondering if this is an issue or a feature?

I"ve been recording on and off all day as part of my job. I only record in 4K 25 fps. The SD Card is a 128gb Samsung Evo Plus UHS 1 U3 100 MB/S. A few times today I have been recording for about an hour or so and the stop recording sound kicks in. I still have a lot of battery left and the SD card still has a lot of space. I tell the camera to start recording again and it does.

Is there a reason why this is happening?

Thanks.

Hi there. We do apologize for the trouble that this has caused. When you experience this issue, can you please confirm what specific message you receive on the screen? Please note that the DJI Osmo Action 4 does support video video-splitting mechanism the same as other aircraft. The maximum capacity of a single file will not exceed 16GB. If exceeded, the recording will not stop but a new file will be generated when the video file reaches 16GB. Please keep us posted. Thank you.

Hi,
It's difficult to tell as I am wearing the Action 4 around my neck at the time.

Thank you for your response, DCooper. Can you please try to perform further testing? Before the test, please back up first all the files on the SD card and reformat it then perform the test to see if the issue persists. If you could provide a short video showing the issue, that would be very helpful for us to further isolate the issue. Please keep us posted. We appreciate your cooperation.

Hey, my osmo action 4 just did shutdown recording after 25 minutes of a 60 minutes scenic flight.. it did record two files due to the 4GB file size limited but then stopped.. really disappointed. This is seemingly a bug? Battery was full Temperature was not exceeded..

Hello, there. Sorry for the inconvenience that it caused you. Please provide the details below for further checking:

>  Device serial number:
>  Firmware version:
> Tested parameters details: Including the shooting environment (environment temperature, windless), Usage status(be mounted on the bike/motorbike, etc/use a hand to hold the camera or other usage status.), Camera parameter settings(Frame ratios, Resolution, Frame rate), Stabilization(RS/HS/...) and whether the DJI Action 4 has connected other accessories.

I hope to hear from you soon. Thank you for your support.

since the scenic flight and event happend are not coming back it wont bring back any memories and whatnot but for whats it worth:

What i can report is that this did happen multiple times during my vacation:

once mounted via chest belt on a horse ride of my gf of about an hour the recording stopped after also roughly 20 minutes.
Second time mounted via suction cup to a window of an airplane (scenic flight)

device serial:
6S6XL9G00A07FZ
firmware when incident happend :
v01.03.07.10

updated firmware after the two events to :
v01.03.08.20
which should not mitigate the issue as per release notes at least.

settings have been:
scenic flight - 4k/30 dlog m manual white balance 5500 RS+
horse ride - 4k/60 dlog m manual white balance 5500 RS+

memory cards used :

SanDisk Extreme PRO microSDXC™-UHS-I-KARTE

I had it happened to me again the other day - I'm beginning to wonder if it's a particular SD card that is causing the problem. It is very difficult to replicate.

Its probably overheating, had this myself, probably worse for you as you have next to your body, mine was on my helmet

I shot in 1080/60fps today and it lasted till the battery died, 112 minutes

The other day it was in 4k/100fps D-log/10bit and i think it lasted about 40 minutes, thing is, it was only 3ºC and i was constantly paddling in my kayak so it had a constant breeze, and it was only in .h264, i initially thought it was in 265, that i would have understood the overheating. At least i know its limitations, downside is, when it gets warmer its just not going to last long at all, I have some testing to do next month at the pool, its a very warm environment...
Edit: its deffo not your memory card and it looks like you have a phantom downvoted, you've said nothing that would warrant a downvote, so darn rude

Sorry, don't mean to intrude, but if recording stops consistently after an hour of recording, it's most likely the SD card. I had this problem once with a genuine Sandisk sd card. It was under warranty and after replacement, no more issue. You may try another card (same storage capacity and speed rating) to confirm this issue is caused by the card or camera itself.
For the SD card, you can try formatting it using the proper formating tool -  https://www.sdcard.org/downloads/formatter/

Sorry but no, deffo not the card, its the camera overheating

You are not setting the Pre-record, or loop recording, correct?

Camera should not stop recording, only time it would is if the battery is depleted, weak, and may show after off back to a certain percentage, if it is overheting, the EU models shut down, the USA will  continue to record, and or shut down  if continued to be overheated.

What can cause a stop, sd card with a bad sector, fully format the card, most do in the camera where a actual computer must be used.
what can  cause to stop, weak battery, depleted battery, Extreme tempeture conditions.

If not monitoring and observing,   is it possible to record the camera while  this happens, to better get an understanding. and pass the  actual seen where it happens to DJI.  If you feel its a bug, DJI must  get a refresh firmware out, since they no longer do this its going to be  sending hte camera in, to purchasing a new one hope you get it resolved, I chalk it up to overheating

I suggest getting it replaced...looks like camera is faulty...probably a bad build

All the action cameras have this limitation, GoPro are even worse by all accounts.
The problem is that its all in one tight little package, nowhere for the heat to go, no fins or fans, being waterproof doesn't help as its all sealed.

i did some testing at home and this is the outcome.

With it sat on the counter at room temp of 17C and overheated,

• 4k/120
• D-Log/10bit
• RS+
• HVEC
• everything else as standard
• the battery had 45m 5s left
  

• 4k/60
• settings as above
• no overheating
• the battery lasted 87m 08s
  

• 1080/24
• lowest settings with everything off (that includes RS too)
• no overheating (didnt expect it)
• battery lasted 146m and 16s

same here
4k120fps. ca55min

I bet its a lot less when its warm out...

use a Smartphone fan

Yeah, good idea, will have to look into something, only problem is, i couldn't use it whilst kayaking

4k 50/60fps
or 2,7k
dont oveheat

first osmo action dont overeat also

Sorry, didnt realise you'd posted again.

Yeah, i concur, 4k60 is ok, although, my test was at 17.5ºC

Side note, having your bike on the front, does that not cause "steering" issues.
I only ask because front weight bias equals quicker turns, whereas rear weight bias results in slower turns, AKA trim when in a kayak or canoe. Something i learnt just last year when on the White Water course. Ive kayak'ed for years, since mid 80's and never heard of that before lol

Just going to add on the end here, I've just realised that when the camera is just sat still like on my tests, i don't think it will matter whether either rocksteady(+) is on or not because when stationary there is no need for the device to compensate. I could be wrong but these are not like DSLR's, the lenses on them have mechanical stability and they constantly adjust, even when stationary on a tripod, therefore one must disable Image stabilisation when on a tripod. In these action cameras its software-based (i believe), if no movement is detected then there shouldn't be any reason for it to be using resources, i could be wrong mind, only way to find out would be to test (cant be asked lol) but if i am right then it would mean that my timed results would be shorter if I was moving.

EDIT:
After posting this i decided to try

• 4k/60
• D-Log/10bit
• RS (previous tests were RS+)
• HVEC
• everything else is standard
• Overheated at 80m 44s
• 10% battery remaining.
• heat test crackconfig file is used.
  

The ambient is marginally higher at 18.2ºC, could that have accounted for the overheating this time round because i doubt it was the difference between RS and RS+

I have just done the exact same test as the post above but without the heat test config file and it ran at 75m 55s, thats nearly 5 minutes less for the UK/EU

I just repeated the test in the post above with the heat test config and with RS+ and i got the same result as before, the battery ran out (83m 32s), no overheating, so RS+ has better endurance than RS, go figure!

Bear in mind that this was a ''tripod'' test, so it would no doubt be different if it was a moving test, imo, RS+ would use more resources when moving.

May I know how large the file is when you guys recording for almost 60mins+?

Basing on the #2 reply, there is a file size limitation. My recording stops around 25mins due to 16GB size, but continue recording after.

My settings that time was,
4k25/HB
D-log 10bit
HEVC
...ambiant temp was around 8-10C

As per my sd card, I am using SDSQXAV-256G-GN6MN

each files maximum size is 16gb, in my opinion its too large but thats what DJI has set it too now due to 10bit regardless of whether you record in 10bit or not.

Thank you for the answer.

So I think i misunderstand what the time you guys are talking about.
Its the time when the battery overheated, not like the  time length of the video?

Thank you for the answer.

So I think i misunderstand what the time you guys are talking about.

Each file is a max of 16gb as opposed to the 4gb as it was before, as for the overheating as per the original post, theirs lasted about an hour under their conditions and recording settings, 4k/30 for me in about 17.5C lasted until the battery died. The time till overheating is varied due to settings and external temps and airflow.
