Mixing : Automation : Trimming Automation : Coalescing Trim Automation

Coalescing Trim Automation
You can set Pro Tools to commit, or coalesce, Trim automation to the main automation playlist by the following methods:
After Every Pass
Trim moves are automatically applied when the transport is stopped at the end of an automation pass. Trim automation playlists are cleared, and Trim faders are returned to zero.
On Exiting Trim Mode
Trim moves are stored separately in the Trim automation playlist until they are coalesced. Trim automation is automatically coalesced on a track only when you take the track out of Trim mode. You can repeat an automation pass, edit Trim automation manually on any of the Trim playlists, or clear Trim automation before coalescing with this method.
*
Even when automation is set to coalesce on exiting Trim mode, you can use the Coalesce Trim Automation command to commit Trim moves at any time.
