You have a script, a deadline, and a folder of AI clips that don’t cut together. Your lead’s face changes between shots, hands melt mid-gesture, and the camera does whatever it wants instead of what you prompted. Meanwhile your credits disappear on rerolls. In 2026, generating a single good shot is no longer the hard part. The hard part is a 2-5 minute film that holds together: consistent characters, deliberate camera work, believable dialogue, and a final cut that clears festival specs and client review without blowing the budget.
This guide is for intermediate creators: filmmakers, editors, agency producers, and solo storytellers who have already generated clips in Runway or a similar tool and now want a repeatable production workflow. We assume you know basic editing concepts, timelines, aspect ratios, and frame rates, and that you’re comfortable in a non-linear editor. It does not teach screenwriting from scratch, cover beginner video-editing fundamentals, or explain how to train custom models. It’s built around the Runway Gen-4 short film workflow from first script page to delivered master.
A straight answer up front: Gen-4 is excellent at atmospheric establishing shots, stylized motion, controlled camera moves, and keeping a character recognizable across scenes when you give it the right references. It still struggles with complex hand interactions, fast multi-character action, readable on-screen text, and long continuous takes. A human has to sign off on story, performance, continuity, likeness and rights clearance, and the final grade and mix. No tool makes those calls for you, and this guide tells you exactly where your judgment can’t be skipped.
