Strengths

  • Accepts input videos up to 30 seconds, far longer than most generation models produce
  • Preserves input resolution up to 1080p and the source aspect ratio
  • Up to five keyframe images for directed edits
  • Text-instruction editing without masks

Weaknesses

  • Most expensive Runway model at $0.28/sec plus a two-second minimum charge
  • Input video must be 2-30 seconds and 30 fps or lower
  • No audio generation
  • Output resolution is bounded by the input, so it cannot upres beyond 1080p

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.

What to understand before using it

Explainers naming the mechanisms this model's own documentation mentions.

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.
