Runway vs Captions
Runway scores 35 to Captions's 30 on public evidence for AI video editing, and they rank #1 and #2 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Runway
Generative video platform (Gen-4, Aleph) with text/image-to-video, video-to-video editing and classic AI editing tools.
+ Aleph lets you edit existing footage with text instructions, which few competitors offer.
− Credits burn fast and clips are limited to roughly 10 seconds per generation.
Captions
Creator video app with AI captions, eye-contact correction, dubbing with lip sync and AI avatars (Mirage).
+ Eye-contact correction and lip-synced dubbing work well on phone-shot talking-head video.
− The subscription is expensive relative to CapCut and many effects feel gimmicky.
