Pocket Cinema Camera footage: frame drops, stutters, stalls
on Aug 20, 2015 at 4:00:32 pm

I picked up a Pocket Cinema Camera for the first time yesterday and shot some test footage. When playing back in-camera I noticed the footage was stuttering and dropping frames. And no, this isn't a 24p motion thing. Same result after footage is ingested into editing system.

Footage is ProRes LT 23.98 1920x1080. Memory card is a Panasonic SDXC I U3 Class 10 64GB. Any ideas why this card can't handle recording this footage?

Just swapped it out for a SanDisk Extreme Pro SDXC II U3 Class 10 64GB card––still dropping frames.

Jason, I don't have the BM pocket cam but check your shutter speed. Not the frame rate, shutter. In my experience with any camera when shooting progressive, the shutter speed needs to be double that of the frame rate. i.e. 24fps @ 1/50th or higher. Each time you double the shutter speed you lose 1 stop of exposure but results in smooth footage.

Thanks, Roger:

It ended up being an incompatibility with my SD cards. Basically, they were too fast! Apparently there are specific cards on the compatibility list. I was trying to use my U3 cards, but the BMPCC only works with U1 cards.

Too fast! I wouldn't have thought that possible but it's one for me to watch out for. Glad you resolved the issue.
