If you shoot or download a lot of videos and store them on your computer, duplicate videos may accumulate on your hard drive over time. Getting rid of them manually can be time-consuming. Luckily, duplicate video finder software can help you out.

This article provides a list of the best apps to find and delete duplicate videos on Mac and Windows PC.

A 3-minute Full HD 1080p video can take up more than 40 MB of space. A 20-minute 4K 2160p video can have a file size of over 2 GB. Videos tend to take up way more storage space than other types of files, and so do duplicate videos. Removing duplicate videos with a duplicate video finder for Mac or Windows can help you quickly free up space.

More than just a video duplicate finder, Easy Duplicate Finder also supports detecting duplicate pictures, duplicate audios, etc.

While the scan is not very fast, the app does a good job of scanning for video duplicates on computer thanks to the powerful file comparison algorithms it uses.

#3 Gemini 2 (Mac)

Compatibility: macOS 10.10 or later

Our take: A beautiful and easy-to-use duplicate video finder

It can look for and remove duplicate video files, audio files, pictures and documents from internal and external hard drives. It also finds duplicates in the Photos library.

Coming with an incomparably beautiful user interface, it uses a smart algorithm to quickly compare the similarity between video files. It scans almost the fastest of the products I’ve tested.

Once the scan is finished, click Review Results. Click Video in the sidebar of the results window, and you can view the duplicate videos. They are displayed in groups. However, I found that it couldn't find all duplicate videos, especially some with small file sizes. In addition, many duplicate photos were not showing. It supports sorting files by name, size or count, which is convenient for you to search files. Expand the group to view their detail information.

Gemini 2


  1. Fast scanning speed
  2. Support videos and other common types of files
  3. Offer 2 preview modes
  4. Provide multiple options to remove duplicate videos
  5. Available in 12 languages

  1. Can use lots of system resources during scanning
  2. Sometimes it’ll miss some duplicate files

#4 Duplicate Video Search (Windows)

Compatibility: Windows XP or later

Our take: An app that uses the video fingerprinting technology to find video duplicates

In addition to duplicate videos, there are near-duplicate videos, such as the resized, downscaled, converted or cropped version of the same video. If you want to find these videos and remove the redundant ones, you can use Duplicate Video Search.

According to the developer, this duplicate video finder for Windows PC locates duplicates and near duplicates using a technology called video fingerprinting. It provides four options for users to customize the locating process: Index, Skip First, Sensitivity and Max Shift.

To only search for duplicate videos, you can set the Sensitivity value and the Max Shift value to zero.

To also search for near-duplicate videos, you can set Sensitivity or Max Shift to a higher value. But note a higher value may lead to more false positives. You need to test different settings to get optimum results. Fine-tuning the Index option can help improve accuracy.

In the test, I used Duplicate Video Search to search a folder where 6 groups of duplicate videos and 4 groups of near-duplicates existed, it successfully found all duplicates but missed most near duplicates.

Duplicate Video Search


  1. Find exactly identical videos
  2. Also find visually identical videos in different size, resolution or format
  3. Support all common video formats, such as MP4, WMV, AVI, MKV and MPEG
  4. Provide a playback feature
  5. Automatically select duplicates for users to remove
  6. Highly customizable


  1. Can’t find all near-duplicate videos in the folder it searches
  2. Take a learning curve

#5 Tidy Up 5 (Mac)

Compatibility: macOS 10.12 or later

Our take: A highly customizable app to find video duplicates

Tidy Up 5 supports various video formats and can be a good duplicate video finder for Mac users. You can also use it to look for duplicate images and music files.

This duplicate file finder for Mac comes in two modes: Simple mode (recommended for beginners) and Advanced mode. There are an array of customizable settings and options, so the interface can be a bit overwhelming. Below is a brief guide to walk you through the process of using this duplicate video file finder for Mac.

In the left column, click the add button to add a folder. Turn on the Simple mode. Click Other Files. Under Duplicates, select Movie files. Click Search. Once the duplicate video content finder finishes searching, click Show Result. Now you can sort, preview, mark and remove duplicate videos from your Mac. You are able to select the video and play it. But the too-small preview window makes it difficult to view. You need to double-click the files to open them in their default applications one-by-one. Tidy Up will auto-mark duplicates for removing after scanning. It also allows you to manually mark files to delete. If you mark all duplicate items in one group, there will be a pop-up message reminding you to avoid data loss.

Tidy Up 5


  1. Good at scanning for duplicate video files
  2. Provide enough useful criteria to customize scan
  3. Also support other file types
  4. Offer 2 modes for users to choose from
  5. Auto-mark duplicate files for removing


  1. Not that user-friendly for beginners due to a overwhelming interface
  2. The preview feature needs to be improved

#6 Auslogics Duplicate File Finder (Windows)

Compatibility: Windows 10 or earlier

As one of the best free duplicate file finders for Windows, it is good at duplicate video search on Windows PC. In addition to video content, it also supports images, audio files, archives and applications.

The user interface is simple and easy to understand. After adding folders or subfolders, you can select which types of duplicate files should be searched.

#7 Duplicate Video Remover Free (Windows)

Compatibility: Windows 10 or earlier

Our take: Video duplicate detection freeware that can compare videos by hash or name

Duplicate Video Remover Free has two comparison types: Strong Duplicate and File Properties. The former is recommended because it can find exactly identical videos by comparing hash.

This free duplicate video finder is very easy to use. You only need to choose a comparison type and specify a folder. Once it finishes searching the specified folder for duplicate videos, you will be presented with a list of the found duplicates.

You can manually select the unwanted duplicates to delete. Or, you can use the Select Automatically feature. But this feature was not useable when I tested this app. What’s more, pop up ads are showing up while using this duplicate video finder free.

Duplicate Video Remover Free


  1. Freeware
  2. Find all duplicate video files
  3. Support scanning iTunes for duplicate videos
  4. Provide 2 comparison types for users to choose from
  5. Very easy to use


  1. The Select Automatically feature not working sometimes

#8 dupeGuru (Windows, Mac & Linux)

Compatibility: Windows 7 or later; macOS 10.12 or later

Our take: An open-source, free duplicate video finder for Mac, Windows and Linux

It is good at finding duplicate videos as well as audios and pictures. Thanks to the simple intuitive interface, it’s very easy to use even for beginners.

Click the add button in the lower left corner and add a folder or subfolder, click Scan. Once the process is finished, the Results window will show up, listing groups of video duplicates. This tool does not categorize all files by type. Here’s a tip. You can navigate to the Filter search box in the top right corner and type in a video format, say, MP4. Hit the Return key. There will only be MP4 videos in the Results window. Now mark the unwanted duplicates, click the gear icon in the upper left corner, and select a removal option.



  1. Free
  2. Open source
  3. Find common types of duplicate files including video duplicates
  4. Offer three modes for different file types
  5. Provide multiple scan types
  6. Allow you to move unwanted duplicates to Trash or a folder


  1. Limitedly useful preview feature


Duplicate videos can be a big hard drive space eater. It’s always a good idea to get rid of them. We tested the most popular duplicate video file finders for Mac and PC. Some of them are able to identify duplicate files of various types such as videos, photos and songs. Some are designed for the only purpose of finding and removing video duplicates.

They vary in usability, performance, versatility, price, etc. When it comes to the best duplicate video finder, we pick Cisdem Duplicate Finder due to its ease of use, versatility and high customization.
