Follow mode, video file reports unknown error

Could someone please assist. I am new to litchi and have a DGI mini2.
When I first used the app, follow mode video playback worked perfectly. Now for some reason I get the report unknown error, yet on all the other modes, playing back video works well? " Your advice would be greatly appreciated."

You proberly turned the drone off without first stop recording.
Put the sd card back in the drone, then turn the drone on and off. This might fix the corrupt video file.

Or you could try this software to fix corrupted video files:

Thanks for the feedback, I reset the app, formatted the SD card and it seems to be working . Much appreciated!!

Having the same issue right now. Hope i can fix it

Anyone have any ideas? I’d really appreciate some help here. It’s super frustrating trying to deal with this issue, and I’m hoping someone might have a workaround or a solid fix. What do you guys think of this tool? https://news.mаcgasm.net/tips/repair-drone-video-files/. It helped me in the past when I thought my footage was completely lost, so maybe it’s something to consider. If anyone has experience with similar problems or knows of another reliable method, I’d love to hear your thought

As Tribar stated above, a corrupted video file can occur when a drone is turned off while in record mode. The generally accepted solution is to power the drone back up (with the corrupted video file on the SD card) and record another short video. This should repair the video file by properly closing it.

If that does not work, either the utility mentioned above or the one that you found will probably work. Why not try it and let us know?
