Video Duplicate Finder is a cross-platform software to find duplicated video (and image) files on hard disk based on similiarity. That means unlike other duplicate finders this one does also finds duplicates which have a different resolution, frame rate and even watermarked.

• Cross-platform
• Fast scanning speed
• Ultra fast rescan
• Optional calling ffmpeg functions natively for even more speed
• Finds duplicate videos / images based on similarity
• Windows, Linux and MacOS GUI

Daily build (You need to download FFmpeg and FFprobe yourself, see below! Please note the attachments of this release are automatically created and replaced on every new commit.)

Get latest package from https://ffmpeg.org/download.html I recommend the full (GPL) shared version. If you want to use native ffmpeg binding you must use the shared version.

sudo apt-get update
sudo apt-get install ffmpeg

Open terminal in VDF folder and execute ./VDF.GUI You may need to set execute permission first sudo chmod 777 VDF.GUI
