Fast, low-cost image-to-video model. It requires a starting image rather than accepting a bare text prompt, and supports a wider set of output aspect ratios than Gen-4.5. Still listed as an active model in Runway's API model registry.

Commercial use — Not established

No licence or terms page was retrieved for this model during research, so the commercial-use position is not established here. Check the vendor's own terms.

No licence page was retrieved, so there is nothing here to summarise. Read the licence before you rely on any of this. Nothing on this page is legal advice, and this site does not tell you a model is cleared for commercial use.

Where the sources disagree

Recorded rather than resolved. Picking the tidier number would hide the fact that the vendor's own pages do not agree.

MCP servers that front Runway

Servers in the media MCP directory whose own description or homepage names this vendor. Absence of a server here is not evidence that none exists: most publish no tool list at all.

9 further servers name Runway with lower confidence and are not listed, because a server naming a vendor may be using it for text rather than media.

Shotcraft hosts no sample output. Judging a model means watching its own showreel with your own eyes, and a clip re-hosted here would be a clip we chose.
