Video download issues

Hi All, can anyone please help. tried to download video underwater footage i had taken on my last adventure. when it comes to exporting the footage to youtube. the file uploads fine. but when Youtube comes to processing the footage it keeps coming up failed. this i have tried twice now.
even when i unload the footage to google drive the same applies. i have even tried to download the footage to the External Sd card.and still no joy. has anyone else has the same problems. any help or advice is grateful.

I think I have been through the same pain as you’re experiencing trying to download videos off Trident. What I do is download the files directly to my devices internal memory (not SD) then transfer to my PC for editing and YouTube upload. Make sure you transfer to PC before delete of files off Trident or the files will be deleted from your device internal memory too!
