When you have finished editing a Panasonic P2 sequence you can export the sequence to a hard disk or back to a P2 card. You can also export individual clips to the P2 format.
The maximum file size for a clip stored in the P2 format is 4 GB. When Premiere Pro exports clips or sequences larger than 4 GB to P2 format, it exports them as groups of 4 GB spanned clips. For more information about clip spanning, see About spanned clips.
The workflow from P2 card to edit and back to P2 card is simple. Import the P2 clips into a project containing a 5.1-channel sequence. Map the source channels to their specified tracks. Place the clips into the sequence, or export them to P2. For more information, see Mapping source and output audio channels.
