Whether for work or play, we use computers for just about everything these days. Over time our hard drives become full of files; files that eat up space and ultimately cause our machines to run slower. Video files are some of the biggest contributors to lost space and a lot of that has to do with how easy it is to accidentally generate duplicate videos.

No one sets out to intentionally make two copies of the same video; it just happens. Duplicates can appear due to an assortment of reasons. For instance, when you make a copy of a video and save it to a new folder; or when you download two copies of the same video file but in different formats. All it takes is forgetting to go back and delete the extra or unwanted copies and there they sit.

The larger and older your video collection is, the greater the chance that there are dozens, if not hundreds of duplicate or similar files slowing your system down.

How does DVS work?

With Duplicate Video Search in your toolbox, you'll never have to worry about unwanted video files hogging your hard drive space again! Using DVS is both easy and fun through our automated process of locating duplicate video files. All you need to do is tell DVS where to look, sit back, and relax while it does all the work for you. No more having to manually compare individual files!

Unlike other duplicate search utilities, our unique visual recognition program actually "watches" your videos. Instead of surface level scans limited to filename or size, the Duplicate Video Search tool compares files in an attempt to find subtle similarities. Our innovative sliding sensitivity scale lets you decide exactly what level of similarity that DVS should be looking for.

Regardless of format or resolution, DVS can find and analyze your videos based on finer factors like conversion, cropping, scaling, and high/low quality to measure similarity levels. Once the potential copies are found, you'll have the option to keep, delete, or move them to another folder. However you choose to handle them, the fact is you'll be gaining a greater awareness over the video content of your drive(s).

Getting started...

This quick how to guide will give you a better idea of how to get started using the Duplicate Video Search tool for the first time.

Step 1: Download Duplicate Video Search

Duplicate Video Search has been confirmed by a number of independent parties such as Download.com, Softpedia and TopShareware and more to be 100% FREE of adware, malware and spyware.

Step 2: Launch the program

Step 3: Add one or more target directories

  • Select which folders to have DVS scan by adding them to the list in the Source Folders box.
  • Click the Add button to add folders to the Source Folder list.
  • Click the Remove button to remove previously selected folders from the list.

Step 4: Setting *optional features

The following features are optional. However, each of them will help you to further refine how the Duplicate Video Search tool goes about scanning for similarities.

Video Reading Options

  • Checking the Fast video reading option will make your video scanning about 2 to 3 times faster by synching the audio and video. Some DirectShow codecs have been known to act buggy. If you experience this problem, simply turn fast reading off.
  • The Skip first __ seconds option helps you to avoid the first several minutes of movies where previews and trailers often tend to vary in length and content. We recommend that you set this to 180 seconds in order to skip the first 3 minutes when scanning movie collections.

Video Indexing Options

  • Specify how many seconds of each video you'd like indexed. The longer this interval is, the more accurately duplicate videos will be detected (less false positives). Warning: the higher your indexing number, the longer the scan will take. We recommend finding a happy medium, or leaving this at the default setting of 3.

Matching Options

  • The Sensitivity slider lets you regulate the degree to which the target videos will be compared before prior to being considered similar. If after running your first scan you find there to be a lot of false positives (or even a lack of) simply adjust the sliding sensitivity scale and scan again. The second scan is always much faster, and it gives you a second set of comparisons!
  • The Max shift can help you negotiate time differences between videos. For example two videos might be the same but have their time signatures off by a few seconds; a scene that occurs in one at 4:03 might not happen in the other until 4:07. We recommended you set this value to 5.

Step 5: Start retrieval

  • The Search button lets you start the inspection process. DVS will scan your selected folders for video copies. Clips that are discovered to have high levels of video similarity will then be grouped together for your inspection.
  • Using our special video fingerprinting process DVS is able to see past surface details like file formats and instead, analyzes the visual content of each video file.
  • Each time you run the Duplicate Video Search scans become faster. This is due to the way that files are indexed. DVS processes only a limited number of seconds for each video, and then stores a signature for each in a cache. This makes it so that the next time you want to run a scan the program can save time by re-using cached signatures and processing only new clips.

Step 6: Remove duplicate video files

  • After the scan has completed, DVS will gather the results as a list of thumbnails. For each video, the program displays duration, date of last modification, path and resolution. The check box indicates the file status; whether it's a duplicate or an original.
  • Based on which boxes are checked (and which are left empty) you'll see which videos that DVS believes are duplicates. You can then act accordingly to move, delete or investigate their similarities further.
  • Please note: in order to avoid affecting your computers performance, we've capped the number of thumbnails that can be displayed at once to 3000.
