Considerations When Originating on Film
When editing 24P material that originated on film, you need to be aware of a number
of special circumstances:
 If you intend to conform the film to match the edited video, you must have its edge
code tracked by a Cinema Tools database. (See “
details on edge code.)
 The film must be transferred to video using a telecine. Typically the offline telecine
video output contains burned-in video and audio timecode, as well as key numbers.
These burned-in values (known as window burn) are invaluable when you intend to
later conform the film. Unfortunately, their visibility is a problem if you also intend to
use the 24P video to produce a video version of the program. For this reason, if you
intend to produce both a conformed film and an edited video version of the project,
you might have the telecine run on two decks simultaneously, one with the window
burn and the other without.
 Whether shooting film or a 24P production, sound is almost always recorded
separately from the picture, with a separate sound recorder. This is often referred to
as shooting double system sound. While 24P productions can record the sound on the
24P video recorder, providing synced sound that is easily captured with Final Cut Pro,
film productions do not have the option of recording sound on the film, so the
sound must be synced to the picture at some point later in the process. The
preferred workflow is to synchronize the sound during the telecine transfer. This
makes it easy to capture the audio along with the video clips for editing with
Final Cut Pro. The Cinema Tools database can track the original sound reel numbers
and timecode and generate an audio EDL that can be used to recapture and edit the
sound at a sound postproduction facility.
