Just over 7 years ago I started identifying the types of metadata that would be useful in post production. One that particularly excited me was derived metadata: using a computer algorithm to derive useful information for use in post production. At the time the only example I could suggest was deriving location and type of location from GPS data.
We can now add another: Magic Keywords in Lumberjack System. Magic Keywords are derived from transcripts and are an addition to Transcript mode, added to Lumberjack at NAB 2015.
