In Trailers & marketing, Runway ranks #2 and Mirelo ranks #5. No independent quality tests found. Ranked on game-dev fit: commercial use allowed; no engine integration stated; API and official MCP server. On Artificial Analysis's video leaderboards, Runway Gen-4.5 is #23 of 31 (text-to-video) and #26 of 82 (image-to-video). Luma was only tested on images, so the two can't be compared.
Sound effects and ambience synced to trailer or gameplay video
Trailer and teaser video shots
What it does
Video-to-sound model (SFX 2.0) that generates sound effects, foley and ambience synced to a video while keeping its dialogue; also text-to-SFX, via a web studio, API and MCP server.
AI video, image and audio generation (Runway Gen-4.5 plus third-party models), usable for trailer shots, teasers and marketing material.
Verdict
For sound effects synced to trailer or gameplay footage; the free plan is non-commercial and watermarked, so anything you ship needs a paid plan.
For generating trailer and teaser shots; the terms don't restrict commercial use of outputs, but Runway may train on your inputs and outputs.
