Is there such a thing as a duplicate video finder that will search duplicate videos based on video/movie comparisons of files rather than just the file size? I have hundreds of duplicate or similar videos on my Mac, they take up much space, how can I find and remove these duplicate videos from a large set of videos of varying formats? – Asked by a video editor

Duplicate videos could eat up your precious hard drive space, often without you even knowing it. They can occur when you import videos from your camera, iPhone, etc. to computer, failing to remember that you’ve already had them somewhere on your hard drive, among other causes.

Duplicate video files, just like other types of duplicate files, are totally useless in most cases. The best thing to do is to find and delete them with the help of a duplicate video finder for Mac or PC.

Stop duplicate videos from swallowing up your hard drive space

Videos tend to be much bigger in size when compared with other types of files such as images and music files. A 3-minute MPEG-4 1080p video can take up around 42 MB space. A 20-minute MKV video in 2160p can have a file size of more than 2GB, which is huge. Given the same numbers of duplicates, duplicate videos will waste far much more storage space than other types of duplicates.

By deleting duplicate videos with duplicate video finder for Mac or other operating systems, one can free up a significant amount of hard drive space. A good duplicate video file remover can effectively and efficiently find all duplicate videos and get them eliminated all at once.
