Which card are you using for 4k video?

Glad you posted this as I was trying to find out what card I may need. Having said that I can always use 1080p.

In addition to the correct card, make sure you are shooting H265 at 30 fps and mastering to 30 fps. I encountered jitter when I shot at 30 and mastered to 24, which is understandable when you think about it. Also, I found that inter frame artifacts can creating aliasing that can look result in frame jitter depending on the compression. I edit in FCPX and used the new Apple noise reduction to reduce artifacts. I found the best setting to be medium NR and a low sharpness setting. This corrected the issues I was having.

I use the Samsung Pro 64&128gb micro SD cards for both my drones. M2P and Inspire 2.
They’re inexpensive from Amazon.
Never have had any problems.
