I just did a firmware update on my P3 a few days back and now my video is jumping like it has buffering issues. I used a different card, did several videos, updated it a second time, even put the videos on different computers thinking that maybe it was my laptop. Nope. Still jumping.
Would anyone know what the issue is with this?

Thanks!!

What frame size and format were you shooting?

Maybe the other SD card has a slower transfer rate? Check it has a '10' symbol on the SD card.
