how do i get back the video i deleted by accsedent?

If an android device. And synced with Google. You can retrieve it from them. (google maps automatically saves photos taken to the MAP history, even if you deleted it from device. Just need to know date taken. small videos are the same.) 

Too many variables. 

If on a hard drive or memory card. Take it to a computer repair shop.  Can be pricey $50+ if they are willing to. Try not to overwrite data.

Accident????>

“Accsedental” deletings can be brought back via compiter store, i think.

Depends on the device the video was on. So sad we don't know... otherwise, we may be able to help.

Example: recovering video from a Windows based computer will be really different than recovering video from a smartphone.

go to a computer place, they know how to get back deleted stuff,i know cause i did that myself one time
