Strengths
Aleph 2 is Runway's high-end model, aimed at shots where fidelity matters more than cost per second.
From 21:9 cinematic through 3:2, 1:1, and 9:16 vertical — more framing control than Gen-4.5.
A fixed 5-second length suits hero shots and inserts that get cut into a longer edit.
Per-second billing from a prepaid balance instead of a monthly plan.
