Set Track Property

Category: Pr Tracks & Clips

Setting IS_MUTED calls Premiere's Track setter immediately. It is not a queued Action and does not flush earlier pending Actions in a shared atomic scope. A later abort or failed queued commit does not restore the previous mute state; other queued edits can still be discarded. Read and retain IS_MUTED first if the workflow needs explicit restoration. Ordinary separate SAFE_AUTO_COMMIT statements settle earlier Actions before the next statement. The pending-queue ordering described here concerns multiple host/helper calls inside one open queue. Preserve the original mute value and restore it explicitly when cleanup is required, rather than relying on Undo. Native Undo behavior for this setter remains unverified; lack of host compensation does not establish whether Premiere itself provides an Undo step. 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.
