Hi everybody,
I have a dji phantom 4, operating it in Beira, Mozambique. On 27 of Oct, there was an event of a 10km run which I filmed with the drone. Everything was working as usual, the app showed it was recording, and I do have the video record backup from the app. When trying to copy the footage to the computer I found out that the video data was not on the SD card, except the last 3 recorded files (starting with DJI0001.mov.) In total I was filming about 11 videos, so the first 8 don’t appear on the SD Card, but they are saved by the DJI GO4 APP. I scaned the sd card with a hidden/corrupted file scanning unit, but didn't find the videos, just old material.
Some extra info, just in case it might be useful: Yes I did stop recording before turning off the drone when changing batteries. The SD card worked fine many times before. It was NOT formatted, and used in the Android tablet before. Maybe that was the error? But when preparing everything the day before, I did a 20 second test recording which was fine. and as said, it did record, but just the last 3 of 11 files.
The day before I had everything recorded fine, but every now and then some stripes appearing on the left or right side, which are clearly related to the propeller movement. It was a very hot day with strong tropical sun. (But I had flown it previously in the same hot conditions without incidents)
Now I am scratching my head with these four questions:
1)Is there anything more I could do to know if the files were written on the SD card and if so to recover the video files?
2)What could be the reason for the problem of data not written?
3)I have copied all the flight data from the tablet. Is there an app which can read flight data and then repeat the same flight? In that way I could maybe try to recover the original quality of the city background for the some photos (which I would export from the 4k video).
4)what could be the reason for the stripes related to propeller movement.
Any considerations are much appreciated.
