Sequence Create Subsequence

Category: Pr Sequences

Creates Premiere's native independent subsequence from the explicit clip Track Items in `items`. Premiere copies whole selected items; source Sequence in/out points do not trim items that cross those boundaries. The block temporarily replaces and then restores the source Sequence selection; it never falls back to ambient selection. `ignoreTrackTargeting` defaults to true. Naming, bin placement, collision handling, and identity outputs follow the same contract as prSequenceClone. Track Item refs are index-addressed snapshots; relist after later structural timeline mutations.

Notes

• Creates Premiere's native independent subsequence from explicit clip Track Item refs.
• Premiere copies each selected Track Item as a whole. Source Sequence in/out points do not trim items that cross those boundaries; isolate exact ranges before calling this block or use a native explicit-range capability when one is available.
• items is required; the block never falls back to ambient selection.
• All items must belong to sequence, which defaults to the active Sequence.
• The block snapshots the source Sequence selection, temporarily selects exactly items, calls Premiere's native createSubsequence, and restores the prior source selection before returning.
• If restoration of the prior selection fails after Premiere created the subsequence, the block deletes that new subsequence and reports failure. This intentionally preserves the promised source-UI-state contract rather than returning an output after incomplete cleanup.
• ignoreTrackTargeting defaults to true so track-targeting UI state does not silently change the requested content.
• name, targetBin, onNameCollision, and the four result variables use the same identity contract as prSequenceClone.
• The returned Sequence is independent rather than a live nest. Its detailed transition, caption, marker, track-effect, automation, time-origin, and Undo behavior remains subject to the documented real-host support matrix.
