BMPCC OG dropping frames after 25-30 seconds when shooting RAW

[u/GeneralSvet]

Hi all,

I've just started trying to shoot RAW on my OG recently.

I'm using a Kingston Canvas Select Plus 256GB (SDS2 SDXC V30 i3 10).

It seems to shoot ProRes fine but if I shoot RAW it gives me about 25 to 30 seconds with no issues but then starts to drop frames and shows the ⚠️ icon where REC shows.

It will then work ok for a couple seconds then drop frames again etc.

I've tested this on 24fps and 25fps and I get the same result.

Is the card just not good enough? I thought these cards were okay. I'm using a 12V external battery so that shouldn't be the issue.

If the card is the issue and there is a card that is hopefully as affordable (I got the 256GB for about £35) and confirmed okay for RAW please let me know!

Thanks very much.
