Blackmagic Forum

Hi !

I just ordered the camera. But I'm having a very hard time concerning the recording media. I have read the official BMD recommended Card List for the CF Module from the URSA Cine. But the description is bothering me : "The following CFexpress cards are recommended for recording to a single card, 12K 3:2 (Open Gate) Blackmagic RAW 3:1 up to 24 fps and 12K 3:2 (Open Gate) Blackmagic RAW 8:1 up to 45 fps."

But what if I want to record let's say in 8K 224fps in 8:1 for a certain project According to the BMD website, that's about 1.3Gb/s of data rate. So any CFExpress Type B Card that has at least 1500mb/s write speed shouldn't have any issue, right ?

I think what I'm trying to say is : can any of you refer me to a specific card they have used without issues so far that allowed them to use any combination of resolution and framerate ?

Thank you SO MUCH !

Hi, I thought this video did a really good job showing many of combinations and how they performed with a sampling of cards.

Thank you, I appreciate you taking the time!

Very interesting video, though I find it weird that none of the three mentioned Angelbird cards are in the list of recommended cards from BMD. But since they're cheap and I've been using Angelbird cards in my 4.6K G2 for the last 6 years without issue, I'll give them a try!

Honestly, if you’ve had good luck with Angelbird cards for years, it makes sense to stick with what you trust. I've seen a lot of people swear by them even for heavy 12K workflows.

Frame rate and compression is the Achilles Heel where a card might be fine with recording 12K or 8K 24/25 fps and Q3 or 8:1.

Turns out those higher compression rates may produce fine results anyway and many may be happy with Q5 and 18:1 up to 30 fps (but never 90 fps).

Test and see what works for you with what deliverable requirements you have. We aren’t all shooting for Marvel or Weta or Nolan or Tarantino (who might be retired now).
