I'm having a routine problem now where I get choppy video and audio in my files. Video skips around, and can't by played well in any software. Anyone else having this problem and have a solution?

Hello!
Sorry for the trouble!
Could you please send the original video to us so that our technicians can help to analyze it?
What kinds of software did you used?
The poor performance may be caused by your mobile device or the unstable WiFi connection, or maybe there's something wrong with the SD card. Please check all those possibilities first.

Right now, I would suggest shooting with different settings and then please check if it's OK.
I'll wait for your feedback. Thanks!

Hi, is it jumping/choppy when played on your PC? or when you play it back on your device?
I use PotPlayer on my PC that plays 4k well.
