i deleted a video accidentally using terminal: sudo rm -R, is there a way to recover still?

It looks like your only route is professional data recovery like uFlysoft:

Step 1. Launch the software to scan the device where your files deleted

Step 2: Preview the scan result files and make mark if it is the one you find

Step 3: Recover files

If it's not in a backup, try using a data recovery product such as the ones listedhere. Don't write anything else to the drive until the files are recovered or you choose not to recover them.
