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.
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.
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.
