Set Project Item Sequence Property

Category: Other

Compatibility-only setter, retained for old scripts and hidden from the toolbox. Its four identifiers IN_POINT, OUT_POINT, ZERO_POINT and PLAYER_POSITION delegate to their canonical seconds properties; FRAME_SIZE is not added to the old allowed set. In/Out/Zero mutations require an atomic transaction; the playhead remains transient. Omitted, empty, whitespace-only or null item uses the active Sequence. Read back ZERO_POINT or PLAYER_POSITION after the mutation commits; the same native quantization and bounded playhead observations documented for prSetSequenceProperty apply to these delegated properties. 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.
