I went out to shoot some videos yesterday and when I got back home I put the sd card in my pc to discover that the last two videos I recorded were corrupted. I went today and record the shots that I missed from yesterday and some more. This time I took my Surface Pro with me to check the videos while on site. I put the micro sd in the computer and almost every single video file is corrupted. I only the first video I took was ok, the other 14 were corrupted.

Anybody knows what may be causing this and how to fix it?

EDIT: Prior to this I edited some videos on my computer and stored in the SD card, could this be the cause?

Why not just check it out?
It's really easy. Clear your SD card and format it in exFAT. Then try again.

I had the same problem with my P4P and it turned out to be a speed issue with the card. Make sure your card is rated for 100mbs and is on the recommended list of SD cards from DJI for the MA.

One sure way to corrupt a video is to power off the drone before stopping video recording; done that myself a few times.

Thank you all for your responses. My sd card is not suitable for 4k but i've only recorded 1080p.On the other hand, i deleted the files that were added later to the card and that seems to have fixed it.

Yes, that was probably aptly done by you. Many of the SD cards don't support 4K videos properly and even I have noticed this with my recordings. Some of my recordings were important for me. I had to use Video Repair software by Stellar to repair those videos. Seemed to work but the card is still creating the same trouble for me.
