IAMCCS Take Router

Once a take is validated, something has to turn that identity into actual render instructions - a concrete timeline position, duration, and audio reference that the backend can act on. That's Take Router: it materializes a single take package into routed timeline_data right before generation runs.

It sits one step downstream of IAMCCS_TakePackage and does the "now actually point at the timeline" work. The take package carries identity; the router turns that identity into the timeline routing that the generation backend consumes, using the multigen resources embedded in the cine_linx. It's the handoff between "which take are we on" and "render it."

Inputs

• cine_linx - the metadata object carrying the take package (output of Take Package or the multigen bridge).
• duration_policy - how to reconcile durations when the visual timeline and the audio package disagree:
  • visual_timeline_truth (default) - trust the visual timeline's duration.
  • hard_fail_mismatch - refuse to run if they differ.
  • audio_package_truth - trust the audio package instead.
• strict_take_package - only required; the router demands a real take package and raises otherwise.
• timeline_data (optional) - pre-supplied timeline JSON if you want to route manually rather than deriving it from the take.

Outputs

• cine_linx - cloned metadata, stamped iamccs_take_router.
• take_package_json - the take identity, echoed.
• timeline_data - the routed timeline the backend will follow. This is the output that matters: it's what drives generation.
• report - status string.

Install

Ships with IAMCCS-nodes:

cd ComfyUI/custom_nodes
git clone https://github.com/IAMCCS/IAMCCS-nodes.git

or via ComfyUI Manager (search "IAMCCS"), restart. Metadata-only node - no models.

Practical notes

The duration_policy dropdown is where the philosophy shows. In a well-behaved Shotboard project, visual timeline and audio should agree, so visual_timeline_truth is the safe default. If your project is audio-driven (a song where clip timing follows the music), audio_package_truth is your friend. And if you're mixing takes across shots and getting subtle drift, hard_fail_mismatch will stop you early instead of letting a mismatched take render. Like Take Package, this node is only meaningful inside the Shotboard/multigen system - a one-off LTX video doesn't need routing, because there's no timeline to route into.
