And for those who may not be aware of Duplicate Video Search
Yet another Bolide product, so I cannot say if it ever will be updated.
But it still is
and well working. Modified
: Only now do I notice my copy calls itself version 16 ! But, ehm... how can a version "16" be so different from normal programs, lacking both this and that normal feature? The user's graphical interface is abnormal, to say the least.
Anyway, the scanning's end result is fine
- and should be, because this is not freeware, but $30
Duplicate Video Search
Step 4: Specify video indexing and matching options (optional)
First, you need to specify how many seconds of each video should be indexed. The longer this interval is, the more accuratelly duplicate videos will be detected (there will be less false positives). However, it takes more time to index long intervals, we recommend to find some optimum or keep default value (3 seconds).
Enable “Skipe first 3 minutes” option if you are going to organize a movie collection. Movies can have similar beginnings (intro of a movie company), so to avoid wrong detections, our program allows to start processing only from 3rd minute of a video (after all intros).
“Fast video reading” option makes video reading 2-3 times faster by ansyncing video and audio. Unfortunatelly some DirectShow codecs may be unstable in that circumstances and lead to crash. Disable “Fast video reading” option in case you faced smth. like this.
Adjust “Sensitivity” slider to regulate how close the detected duplicates should be. It is recommended to change this option after running a first scan, in case there are too many false detections or vise versa. Second scan is usually pretty fast, cause Duplicate Video Search stores all indexes to the cash and so does not have to repeate video indexing twice.
Some video duplicates can be misaligned in time, i.e. same momemnt can take a place on 2:03 on a first video and and on 2:07 on a second one. To accept this, set “Max shift” value to 5 seconds.
Step 5: Start retrieval
Click the “Search” button to start retrieval. Duplicate Video Search will scan the selected folders for duplicate video files. Found clips are compared against each other and grouped together if they have similar content.
Since there are many video formats in the world, our software determines duplicates on the basis of the visual content of files. For this, the program processes each file and generates it`s short signature which is compared against signatures of other files. This process is also known as video fingerprinting.
To index video, Duplicate Video Search processes only limited number of seconds of each video and stores a calculated signature in cache, so that next time you need to organize video files, the program can re-use cached signatures and process only new clips.
