Step 1: Add Corrupted Video
Go to the location where your corrupted video file is and retrieve it to the repair tool's interface. Do this with the option "Add video and start repairing". You can also add the corrupt videos by simply choosing the "Add" button
Step 2: Repair Video
Go to the bottom right of the interface and choose the "Repair" option. This will begin the process of quickly fixing your corrupt video file
Step 3: Preview the Repaired Video

By implication of the pop-up information, you should endeavor to choose a new destination for your video file to be saved, no longer in "C" drive. Ensure this happens by first of all choosing "New Folder" before you choose the "Restore" option. Give a new name to this folder containing your repaired video file and wait for a few seconds as your files get saved.
