To prevent future loss and video corruption, you can take care of a few things. For example, you should know where the downloaded files are stored so that you can create a backup of that folder or something else. Also, you can select the file path before starting the download. So, you can store them in a safe place because even sometimes people don't know where the video file is going to save into the PC. They just click on the Save button and when they come to know that they don't know the specified path then tend to cancel the download and this leads to the video's corruption. So make sure, you have determined a safe path before storing any file.

It is always advised not to alter or update the video & audio settings unless you're not sure about what results in it will bring. and if you did so and now facing the issue of the corrupted videos then I highly recommend using the Wondershare Video Repair tool and fixing things straight away.
