Runway: our review

Runway generates videos from text or an image, and also offers editing tools (background replacement, motion tracking, shot extension). What sets Runway apart from most video generators isn't just the quality of its models: it's its credit-based billing, which turns every attempt into a measurable expense — even when the attempt yields nothing usable.

What the credit actually pays for

Every action has a cost in credits: a standard-resolution image consumes 8 credits, a second of video generated with the Gen-4.5 model consumes 12. A team preparing visuals for a marketing campaign can therefore work out a monthly budget fairly precisely from the volume of credits included in its subscription. The point that often escapes a new user: the credit pays for the computation, not the result. Runway's help centre says it plainly — if the generation completes, even with a distorted face or a rendering that doesn't match the prompt, the credits are consumed and not refunded. Only a technical generation error triggers an automatic refund. In practice, tweaking a prompt ten times to get the right shot costs ten times the price of a single generation, successful or not.

Who owns the video, and what Runway does with it

On ownership, Runway is direct: the company claims no rights over users' inputs or outputs, and imposes no restriction on their commercial use on a paid account. The trade-off appears in the same clause of the terms of service: by generating content, you grant Runway a non-exclusive, perpetual and irrevocable licence to use your inputs and outputs, explicitly for the purposes of training and improving its models. No opt-out procedure is described to avoid this, unlike what Canva offers in its own privacy settings. Another nuance worth knowing before building a visual identity on it: Runway itself warns that "outputs may not be unique" and that a similar prompt can produce a close result for another customer — the licence is never a guarantee of exclusivity.

Reservations worth knowing before rolling the tool out widely

Two points deserve raising before a team-wide deployment. First, budget risk: an intensive experimentation phase, normal during testing, can consume a disproportionate volume of credits relative to the videos actually delivered, since every attempt counts. Second, the question of training: a company handling sensitive visuals (prototypes, brand identity in the works) should know that this content can feed Runway's models with no identified way to opt out, unlike other publishers in the sector that offer this choice.

Our recommendation

For a team producing short videos at a steady pace and able to keep its trials in check, Runway offers a level of cost control that few competitors display as clearly. For a tight budget or content that must stay out of a third party's training data, it's better to compare with other video generators before committing, or start on the free tier to measure your own credit consumption before paying.
