i took some video footage yesterday of a couple. The first session I took about 8 video clips and the flight log shows that approximately 8 min of video was taken. I then changed batteries and took about 13 video clips in the second session which amounts to 15 min of video. Only the last 9 clips is visible on the SD card, all the other video clips are gone. I have tried recovery on the disk and all the old deleted files are recovered but nothing of the other files I recorded yesterday are recovered. The flight log shows thumbnales of the files that were recorded. The version of Dji Go is ver 2.8.3 and the firmware version on the drone is v1.8.80. Anyone experienced this and please advice if it is possible to recover the footage and how.
