After importing an AAF file and prior to recapturing it, it is strongly recommended to consolidate your clip in Backdraft Conform. This ensures that you do not capture all the extra media that was likely captured during the offline edit. This step should be performed even if a similar process was performed in the Avid application.
You can consolidate clips in the clip library. See Consolidating Clips in the Clip Library.
In general, it is recommended to use the All Tracks option, available from the Consolidate option box, to consolidate all segments of an unlinked clip.
