For Each Track

Category: Pr Tracks & Clips For Each Track block screenshot

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.
