Carnac is a system that fills in tag fields using other available information about a file.
It is most useful for videos since video files seldom have tags.
A filename like "Seinfeld S02E05 The Apartment.mkv" should fill:
- Series: Seinfeld
- Season: 2
- Episode: 5
- Name: The Apartment
A video in the miniDV format should be considered a Home Video.
A video that's 2 hours long should be considered a Movie.
When It Runs
Carnac should be thought of as an extension of tag reading. When reading tags from a file on fresh import, or when doing Update Library (from tags), Carnac will be used to fill empty fields. It makes no changes to fields that are present in the tag -- it only fills empty fields.
You can also run Carnac manually by using Library Tools > Fill Properties From Filename and selecting 'Automatic' as the method. In this mode, Carnac will overwrite existing fields (instead of only empty fields). A full preview of changes is available in the tool.
False Positives / Tuning
Carnac tries to be certain before filling a tag.
In the rare case that you encounter issues, please report it on Interact. Please include a full filename (including path), codec, duration, and any other information about the file when reporting the issue.
