Squeeze has several options to import your source files:
Import a Source File
The Import File option allows you to select and import video stored on your hard drive or your network drive(s).
Watch Folder Option
A Watch Folder is a folder Squeeze proactively monitors, or "watches", for source files.
The Capture option allows you to capture content from a connected digital video (DV) source directly into Squeeze.
Squeeze 8, and higher, allows you to input source files directly from a non-copyrighted DVD.
