Video simili duplicate cleaner

macOS / Photo et vidéo

Find and remove duplicates : Video simili duplicate cleaner is a program that can find duplicate or simply similar video files.
Video simili duplicate cleaner compares the actual video content regardless of different format or compression used, while other software only find identical files (digital video fingerprinting).

Features :
- Supports finding files in Apple Photos and on disk, to save more space. 
- Simple, easy to use graphical user interface for comparing videos.
- Supports all widely used video formats.
- Manually select videos to remove, or use automatic selection criteria.
- Safely move duplicates to trash (you must empty your trash afterwards to really delete the videos), or to a folder of your choosing.
- Specify locked folder, to make sure the videos within are never moved.
- Multithreaded operation, makes full use of all available CPU threads.
- Employs two powerful image comparison methods: pHash (perceptual hashing) and SSIM (structural similarity).
- Uses caching for blazing fast second runs.

Usage :

- Main window
After starting the program you must enter which folders to scan for video files. Folders can be added by typing them in, dragging and dropping a folder onto the window or using the folder browser button next to the input box. You can add Apple Photos library(ies) to the search by using the dedicated button on the right of the browse folder button (for more information see the dedicated section. All folders (or libraries) must be separated by a semicolon ( ; ).

Comparison is started by pressing the "Find duplicates" button and all video files in selected folders are scanned. A lengthy search for videos can be aborted by pressing the button again (that now reads Stop). Note: some videos may be too broken for the program to read and will be rejected.

- Comparison window
If matching videos are found, they will be displayed in a separate window side by side, with the thumbnail on top and file properties on bottom. They are sorted from biggest file size to smallest, to make it easier to save disk space.

Clicking on the thumbnail will launch the video in the default video player installed. Scrolling on the thumbnail with the mouse wheel will load a full size screen capture and zoom it, allowing a visual comparison of image quality. Clicking on the filename in blue will open the file manager with the video file selected.
File properties are colour coded:

Green: "better" property (bigger file size, earlier date, etc.)
Orange: both videos have same property
Black: "worse" or not comparable property
Prev and next buttons: cycle backwards and forwards through all matching files.
Delete: Delete the video.
Move: Move the video to folder of opposite side.
Swap filenames: Change filenames between videos.

Beware that a poor quality video can be encoded to seem better than a good quality video.
Trust your eyes, watch both videos in a video player before making your decision of which file is better in your case.

- Apple Photos specific information:

If using iCloud photos, be sure to enable "Download Originals to this Mac" (Open the Photos app, Choose Photos > Preferences, Select iCloud, then click Download Originals to this Mac). Only videos that are downloaded to your device can be scanned.

Instead of trash, if a duplicate is detected inside the Apple Photos library and is deleted inside our app, it will simply be added to an album within Apple Photos, so you can review them and delete them from within Apple Photos. After using our app, you must open the album 'Trash from Video simili duplicate cleaner' inside Apple Photos. Inside this album, select the videos then press 'cmd' and 'delete' (or right click while pressing 'cmd', and select the option 'Delete', but not 'Delete from album' !!!). Finally, empty Apple Photos' trash !

Quoi de neuf dans la dernière version ?

# New

Automatic cleanup can now keep either the larger or smaller video when matching videos differ only by file size.

# Improvements

Finding the next or previous matching video pair is now faster and more responsive, especially in large libraries.

Matching continues in the background while reviewing duplicates, reducing waiting between pairs.
