For Each Track

Category: Pr Tracks & Clips

Iterates tracks of a sequence (filtered by kind and order). If you provide indexVar, the block also exposes the current zero-based iteration index. Use kind to limit which item type the block should include. If sequence is omitted, the block uses the active sequence when supported.

Inputs

Input	Required	Value Kind	Types	Enum Values
trackVar	yes	string	—	—
indexVar	no	string	—	—
sequence	no	expression	—	—
kind	no	expression	—	—
order	no	expression	—	—

Notes

• Iterates tracks of a sequence (filtered by kind and order).

Examples

Iterate All Video Tracks

Iterates all video tracks in the active sequence and collects their names.

Traverse Nested Sequences With Deduped Worklist

Traverses the active sequence and nested sequences through a pending/seen worklist so nested sequence refs are not processed twice.

Export Timeline Clips As Separate Files

Exports matching video Track Items as the complete timeline result, as an isolated clip with directly applied effects, or as the used source-file range. An `.epr` preset remains required for this multi-mode tool.
