BMPCC 6K PRO stopped recording at worst possible time

For about 15 minutes, My BMPCC 6K PRO stopped recording after approximately 1-2 minutes. I discovered this at the worst possible moment: when I was filming a wedding ceremony, right after the father gave away the bride (so I missed that part).

For the next 15 minutes I had to keep checking if it was still filming, as it just stopped after a maximum of 2 minutes. And then... It just kept on rolling for no apparent reason. Didn't change the settings, didn't change the memory card. Didn't change anything before the ceremony either; I just used my regular settings.

I figured the heat outside couldn't be the issue (it was 25 degrees celcius / 77 degrees Fahrenheit).

My recording settings where:
-BRAW 5.7K
-Constant Bitrate
-12:1
-24fps

I used the SanDisk Extreme PRO V30 UHS-1 memorycard (512gb).

My question: how do I prevent this from happening again?

Thanks!

As long as there was nothing obstructing the flow of air to the camera, my suspicion is that it got too hot for the media card. It’s going to be 30 degrees here tomorrow so I’ll run some tests using my media but I don’t have your card specifically.

Edit
No need to test today in the heat when the rates speed of the card was insufficient for use on a BMD camera.

V30 is too much lower for my knowledge for braw 5.7k.
In the approved media list you cannot find V30 card, at less V60 and no UHS-I no SanDisk Sd.
12:1 for 6k require since 81mega per seconds at 30 fps, far from v30 performance.
Also with different v60 I cannot record for more than 1-2 minutes and most of time was scene related.

That card is definitely too slow.

Just to Play, i tested SD V60 lexar that i used with pocket4k, on pocket 6k.
on a scene with medium details in deep focus (more data rate required) you cannot record 6k 24fps, 5.7 24fps, stop after few seconds, if i switch to 4k at 24fps keep some minutes.

if you start with less dof you can start to record at 5.7k, but later data rate grow and stop to record.
If you want to record 6k you should buy faster card or usb disk, all approved media from bmd, don't risk your work for few bucks more for support.

I think it's amazing that you managed to blame everything except for the slow as molasses consumer card -that's definitely not on the recommended media list- you used to shoot a wedding (!) of all things.

I experienced this EXACT same issue. I only run ANGELBIRD cards which have 560mbps recording speed.

Maybe we could not treat each other with such arrogance. I have 22 years of experience as a cinematographer. So, now what?

This is in fact an issue that needs addressing asap. I can no longer bring this camera to shoots as a second camera until the issue is understood and resolved.

I hope someone offers some real advice here, not just more BS quips. Shame on you guys.

@Ryan
The same symptom doesn't always indicate the same cause. A V30 card is definitely inadequate.
Such issues with an Angelbird must have a different cause.

Yes, Mr. Plank. You might be correct, but it doesnt mean that you are. It could very well be the same issue. I dont see you offering up any relevant information here that actually helps up learn. But thank you for your reply. I appreciate your time.

Any one else experiencing this issue? Anyone aware of any known bugs?

Thanks in advance.

Ryan, please provide more information about your specific card that failed on the BMPCC6K Pro camera.

Which cards were you using? What resolution and frame rates were you using? Any other salient factors that might affect the card? How was it formatted, exFAT or journaled, HFS+? Was it formatted in camera before that recording session? What were the ambient temperatures?

how do I prevent this from happening again?

I can say that unfortunately the Angelbird CFast2.0 cards do have an issue with the PCC6k Pro.
I have three 1Tb cards from Angelbird (2 are from the very first batch when they got released years ago, 1 is from 2024). They work flawlessly in my UM46k, UMP G1, PCC4k. But do keep stopping in my PCC6k Pro.
Cards working with my PCC6k Pro are Transcend 256 GB CFX650 and Sanddisk Extreme Pro 512GB.

Thanks, Robert.

Perhaps Tim Schumann will update the current sticky note regarding Angelbird cards with this information.

SD Cards are too slow for any viable recording of this camera.

Great for loading Luts but nothing else. I suggest using SSDs with a fast sustained write time that are formated prior to recording.

SSDs and Fast both sure SATA for the connection. The write speeds matter regardless of the tests Blackmagic did on them.
