Runway is a high-end AI video generation and editing platform (flagship Gen-4.5) that also generates and edits images, with a browser timeline, motion controls, lip sync, and TTS — a pro-grade generative film studio, not an all-in-one content suite.
Runway Aleph does in-editor object add/remove, inpainting, green screen, and 4K upscaling.
Gen-4.5 ranked #1 on the Artificial Analysis text-to-video benchmark with strong physics, motion, and character consistency.
Runway has a browser timeline plus Motion Brush, Act-Two, and Aleph; PrismPoster’s timeline also generates image, video, and music at the playhead.
Runway Gen-4.5 generates synced sound effects, ambient music, and dialogue in-video, but not standalone full songs with vocals, lyrics, and separated stems.
Runway covers image, video, and native in-video audio (SFX, ambient, dialogue), but not standalone song creation or social-format breadth.
Motion Brush, Act-Two performance capture, Aleph video-to-video, frame interpolation — controls all-in-one tools lack.
Runway embeds invisible C2PA on every tier and shows a visible logo only on free; PrismPoster burns a visible AI label on every export.
Choose PrismPoster when you need one OS — image, video, a generating timeline, full songs with vocals and stems, and Creator Cast — with visibly labelled exports. Choose Runway when raw generative-video quality and pro film controls are the single most important thing.
Filmmakers and motion designers who want the highest-quality generative video and deep cinematic controls above multi-format breadth.
