Video not recorded

[Storyline]

Yesterday I had a test flight to experiment with some of the intellgent flight modes and flying techniques which look good on video.

I have just come to download them so took the SD card out of the aircaft and when I looked at it on the PC i had 3 video files but each had just 1KB in them. I think I stopped the video properly but even so in the past I have crashed out of the app without stopping video and it has still been recorded.

I have just had a test flight and successfully recorded 2 videos.

Anyone any idea what might have happened ?

You will want to verify that you actually started the video (being sure that the shutter button changed from the full red circle to the smaller red square) AND that you stopped the video BEFORE turning off the drone.

Also, be sure that the SD card is fast enough.

As far as I remember I did all that and even if I made a mistake I would be very unlikely to do it three times. The card is very fast but maybe it did not mount properly. It did take photos though - weird I
