Sound
Veo makes sound with every clip: ambience, effects and spoken lines. Runway's own Gen-4.5 and Gen-4 Turbo clips are silent; through Runway you can run Veo 3.1 with sound, or add audio separately with ElevenLabs.

Working with existing footage
Runway's Aleph 2 restyles a video you upload, changing the look, the weather or the time of day while keeping the motion, and Runway can upscale clips. Veo makes new clips from text, a first (and optional last) frame or reference images; it doesn't restyle footage.

Image to video
Both animate a still. Runway's Gen-4 Turbo is fast and inexpensive, 300 tokens for 5 seconds. Veo animates from a first frame to an optional last frame and adds sound.
