I did start to write this in the 2018 Golden Hour Challenge but moved it here after my long winded reply below.
I decided it was about time to use Litchi as I’ve owned it for about 18 months now and only flown with it a handful of times, never done any more than just fly manually.
I set up a mission late last night, imported the necessary into Google Earth to check the heights etc, done any alterations to correct the Mavic trying to pass through Twmbarlwm Hill Fort, went to bed at 1am, back up at 5am and off we went, climbed the hill/mountain, took some shots of the first part of the golden hour with the camera, froze my tits off in the 20mph winds, 10 minutes later I got the Mavic out, set it up and off I went in Go4.
I took some great shots with us, (myself and my daughters boyfriend), and the Hill Fort silhouetted against the rising sun, I landed it and changed the battery and shut down Go4 and started Litchi, off I flew towards the start point because I was on the top of the hill rather than where I had planned the mission start.
I hit waypoint and start mission etc, off it went flawlessly with us watching it all the time and I was loving what I was seeing on the screen of the iPad, it finished its mission and I hit RTH which I never do and it came home as it should etc.
When I got home, I put the card in the reader, all 80+ photos and the video pop up on the PC as normal, I click to play a video and that’s where it went tits up.
File explorer closed, no video played, and now the PC is telling me I have to format the card, I have tried all sorts to try and recover the data but nothing yet
The card is now showing in RAW instead of NTFS or FAT32.
I have watched endless videos and tried quite a few things but I’m fearing the worse that all data might be lost
The card does show as full, I had forgotten to format it on startup, probably because of being a bit nervous about trying Litchi, and it did show as full when it was approaching its last waypoint.
Since trying to watch the video I did try the card back in the Mavic but nothing is showing so I can’t even recover the photos I took with Go4 and the panos etc.
Does anyone have any ideas on how I can recover the footage?
One from the camera.
