Track Item Trim

Category: Pr Tracks & Clips

This is a low-level advanced edit primitive over Premiere's coupled start/end/source-in/source-out actions. The four optional values are not independent field assignments: changing a timeline edge can change the corresponding source point, and changing a source point can change the corresponding timeline edge. Do not use four-field trim as a slip operation. Use prTrackItemSlip when timeline edit points must remain fixed. Do not use this block to place source snippets. Use prSequencePlaceItem with sourceInSeconds / sourceOutSeconds. Use onError to decide whether errors stop the script, continue, or return false when the block supports it. If storeResultIn is set, the block also writes a result variable back to your graph. Use startSeconds and endSeconds to retime the item on the timeline, and inPointSeconds/outPointSeconds to retime the source portion inside it.
