Goal is stable playback and usable RAM previews for a 4K multicam timeline on a system with limited RAM.

The decision is between After Effects Proxy workflow and Dynamic Link for compositions that reference Premiere Pro sequences or nested comps with layer transforms and effect stacks.

Performance behavior is version-sensitive and depends on codec, effect complexity, nesting depth and storage speed, with no documented deterministic indicator for when a live link should be collapsed.

Which approach preserves RAM preview length under a fixed RAM ceiling for 4K multicam playback with frequent editorial changes? Is there a documented threshold for nesting depth or effect complexity at which a Dynamic Link source should be collapsed to a rendered intermediate?
