When importing AAF or OMF tracks into Pro Tools, you can specify where the imported tracks are placed in the current session. Times are indicated in timecode.
This option places tracks at the locations where they were located in the source session. For example, if the current session starts at 00:01:00:00, and the session from which you are importing starts at 10:00:00:00, the earliest imported tracks can appear in your session is 9 hours and 59 minutes after the start of the session.
This option places tracks at the same offset from session start as they had in the source session. For example, if the source session starts at 01:00:00:00 and a contains a track that starts at 01:01:00:00, and the current session start is 02:00:00:00, the track will be placed at 02:01:00:00 in the current session.
This option places tracks relative to their original session start time. For example, if the current session starts at 00:01:00:00, and the session from which you are importing starts at 10:00:00:00, you can reset the start timecode to 00:01:00:00, to avoid placing files 9 hours and 59 minutes from the start of your session.
This option changes the start time of the current session to match the start time of the AAF or OMF sequence being imported. When this option is enabled, the
Map Start Timecode to hh:mm:ss:ff option (and its timecode entry box) are disabled.
