Product overview
Runway is most useful when the unit of work is a shot: a few seconds of movement to explore before committing to a finished sequence. A reference image can establish the subject and composition, while the generation request describes what should move. That makes it suitable for comparing a camera move, an atmosphere or a transition as a visual treatment. It does not remove the need to select takes, maintain continuity and assemble the final edit.
Generating a new shot and altering recorded footage are different decisions. For an existing product video, the question may be whether to change its setting or lighting while retaining the underlying performance; that is an editing task rather than a request to invent the whole scene. Choose the workflow first, then check its input requirements and entitlement. Review results at shot level for object consistency, readable text and unwanted changes before spending more credits on variants.
What Runway offers
- 01Generate short clips with video models such as Gen-4
- 02Change backgrounds, objects, or lighting in existing footage with Edit Studio
- 03Iterate on images and video in a credit-based workspace
A practical workflow
- 01Choose one shot and decide whether you need generation from a reference or changes to existing footage.
- 02Prepare the input image or clip and describe one visible motion or edit rather than several competing actions.
- 03Compare short variants for composition, movement and continuity with the adjacent shots.
- 04Keep the selected result for the final edit after confirming export settings and credit use.

What makes it different
Choose between inventing a shot and modifying footage you already want to keep. The input, editing entitlement and review criteria depend on that distinction.
Who should consider it
- Creators prototyping short video
- Marketing and film teams revising existing footage
What to verify
- Confirm whether the selected model requires an input image and which clip lengths it supports.
- Check the entitlement for the editing tool separately from the generation allowance.
- Inspect faces, lettering and unchanged objects frame by frame; a compelling preview is not a finished sequence.
Frequently asked questions
Should I generate a new clip or edit footage I already have?
Use generation to explore a shot that does not yet exist. When the performance or product footage is already usable, an editing workflow may target the background, lighting or objects. The inputs and plan requirements differ, so choose based on what must be retained.
How can a team compare variations without wasting credits?
Keep the input and intended shot constant, vary one motion or visual treatment, and compare a small set before expanding. Check the selected model's duration and credit table rather than assuming every request has the same cost.
