To restore a screen recording video, first check your Trash folder. If it’s not there, try restoring a snapshot from a Time Machine backup. If you emptied your Tras folder and haven’t enabled Time Machine, use data recovery software like Disk Drill or PhotoRec. Here’s how:
Download Disk Drill.
Scan your system drive.
Filter results to show only MOV and M4A file extensions.
Select the files you want to recover, then click the Recover button.
Choose the destination for your restored QuickTime files.
