BMPCC 6K Pro: Laggy / Shuttering footage

PostSun Jan 05, 2025 7:56 pm

Hi guys, just bought a BMPCC 6k pro and when I was test filming some stuff I found out all my footage is laggy / shoppy.

Attached a video link for reference.

Does someone know what the issue is?

Does the camera keep recording when frames are dropped? Maybe your card was too slow.

The record button shows that frames are dropped. Looks like either card to slow, or if external media, maybe a bad cable or drive.

Well I have an SanDisk Extreme Pro 1 TB V60 280MB/s, do you know what is required?

I've had excellent results with this on my P4K.

Under Support, BMD publishes guides to compatible media for each camera. Also, there's a setting on the camera which will force recording to stop if it's dropping frames, which is what you want, for your own safety.

Some media, recommended or not, will work at higher compression ratios and/or lower resolution, but not lower ratios and higher resolution, on the same camera. The Sandisk card you used may work at HD or 4K/24fps, at higher compression..... You'd need to experiment, Or spend more for the recommended media.

280 MB/s is the read speed, that card writes only at 150 MB/s and is way too slow for the data rates of the PCC6k Pro.

SanDisk Extreme Pro CFast 2.0 512GB does work well with that camera.
Saying "Thx for help!" is not a crime.
