HELP! Video file on R6 disappeared from SD card!

[Hollasue]

I have 2 128GB cards and have R6 camera set to record to both (which it didn't,but that's another discussion). I recorded 3800 images and 4 videos while whale watching. I watched the videos on boat, 'edited' them, trimmed beginning on two and end one one,  saved one as new file and the others as overwrite. I returned home put my card in card reader, no videos, they all have disappeared! Put them back in camera, gone too! HELP!

Definitely look into the reason behind the not-recording to both cards (ensure your settings are set to simultaneous record). Ensure you're not using micro SD cards in adapters (bad idea).

Unfortunately, I think you'll need to look into data recovery services to try to salvage the data.  If these are SanDisk cards, there may be software you can try to see if data is still there.

Also, I would probably shy away in the future from editing footage (and re-saving files) on the camera itself.   Just to rule out any issues there with re-writing that could lead to corruption perhaps.

Personally, I separate the processes of taking an image from those of post-production.  By breaking down the elements into different stages it reduces the chances of one impacting the other, especially if something gets corrupted.  I would take the photos and video, download them to a computer drive and THEN make whatever changes you want using the copied images. If anything goes wrong you should have the originals as your fall-back.
