You can recover but it's not 100% sure
unless those deleted videos are not fully overwritten(if you continue to take ).
First of all
, DO NOT take any more videos with the memory card or stick that you want to recover from in case you may quite possibly ruin your chances of video recovery.
Then take some video recovery software
to see if you can recover some or all of your deleted videos. Take the software and see?
If you are running Windows, turn to this video photo recovery software
If you are running Macintosh, refer to this Mac data recovery program
Just install the program on your computer, then connect your cam memory card and start to the scanning process.
Lastly you should remember
- Do NOT try & write anything back to your Nikon memory card until you can recover your pictures to safely!
Happy the holiday! Greetings
