Same day, same place, more video, but the last video does not work.
(Of course, it's the most important video.)

Only message: ...Unable to play file. The player may not support the file type or codec that was used to compress the file...

Could it be the problem of the player as this is what it’s reporting ?

More video the same day / flight, but only one does not go.
I have also tried other player, od it is the same.
Also tried loading it to phone , but the same problem - does not work.

OK, then I put the memory card back in the drone, connected to the phone with transmitter and drone, and has downloaded the video from drone directly to phone.
From phone to computer.
And it WORKS.

I had this happen and to fix it I just put the card back in the drone, did a short recording, and then the corrupt video could be copied played normally.

Happened to me also. I just guess here, but it can have something to do with order of shutting down MM.
What is the correct order btw ? App > Drone > Controller ?

Good job! Neat workaround.
