To open the Preferences menu, go to File -> Preferences.
The menu includes all the parameters that tweak the Video Search process:
- Path to Fingerprinting Files – this is a folder where indexing files are stored. The indexing files might take up a lot of disk space if you process many files or many long files. So be sure to use a disk with enough free space.
- Path to Reports – a folder where the resulting reports are stored. This folder is used to restore the results when you restart the application.
- Remove Archive Fingerprinting Files – once enabled, the application removes indexing files generated for the video archive folder. Helps to save disk space. But if you plan to check the same video archive many times, it’s recommended to keep the option disabled – this saves time for file indexing.
- Normalize Content Videos – whatever is the original file resolution or frame rate, normalize it to an internal format for better search accuracy.
- Normalize Archive Videos – the same normalization but for the video archive files. Note please that the best results you can get when all the files are of the same resolution. So if all the files have the same resolution, you can skip the normalization stage.
- Clean Up on the Start of the Search – once enabled, clear the internal search database every time you start the search process. To avoid results duplications, it’s recommended to enable this option.
- Remove Archive Files that have no matches - once enabled, remove files from the Archive folder if there are no matches detected during the video search process.
- Use Reports - sets an interval to use the previously generated results. Possible values: all reports, one week, two weeks, or a month.
- Clean Up Content Database – manually clears the internal search database.
- Target Tolerance – an interval for the target (from video archive) files where the detected segments are considered as a single fragment. For example, if detected segments are 1 second away from each other, and the tolerance is 2.0 then both segments are included in the resulting report as a single fragment.
- Source Tolerance – like the target tolerance, but for the content files.
- Frames Tolerance – an interval between the segments in frames to split the detected segments.
- Minimal Detected Duration – a threshold for the detected segments. If the segment is shorter than the value of the preference, it is excluded from the resulting report.
- Accuracy – sets the preciseness of the results. Possible values are “Similar”, “Accurate”, and “Precise”.
- Parallel Processing instances – sets how many files can be processed at the same time.
To implement the updated preferences, click on the Save Preferences button. When you change the accuracy settings (tolerance values, duration, or accuracy level), the resulting reports are refreshed once you save the updated preferences.
