If you do not have a transfer log, or if the transfer log is incorrect, you need
to add the information manually. If you log clips using the Logging tool,
the Avid system uses the A frame as the default pulldown phase. You
might need to edit this value.

You can set a default pulldown phase in the Film Setting dialog box. See
“Setting the Pulldown Phase” on page 171 (24p projects only).

For matchback projects, you need to log key number information before
you can log pulldown information.
By specifying the pulldown phase in the Pullin column, you accomplish
the following:
• You ensure the clips will start with the correct frame for the pulldown.
Otherwise, you might experience inaccuracies in key-number tracking
and in the cut lists.
• You indicate where the pulldown fields are located so the Avid system
can accurately eliminate the pulldown fields during the digitizing
process, leaving you with a frame-to-frame correspondence between
your digital media and the original 23/24-fps footage (23p or 24p
projects only).
To do this, you must indicate whether the sync point at the start of each
film clip transferred to tape is an A, B, C, or D frame, as described in the
following section. In most cases, the sync point is the A frame.
