Video-to-video transforms
Keep the motion, change the aesthetic. Live-action to animated, sunny to rainy, photoreal to painterly.
Performance transfer
Runway Act Two drives a character's performance from your reference video. Consistent character expressions across shots.
Upscale to 4K
Topaz Video Upscale reconstructs detail and sharpens edges. Takes 720p to broadcast-ready 4K without softness.
Act Two — character performance transfer.
Runway's Act Two is a breakthrough for AI film. Record yourself delivering a line and the model puppets your character to match your facial expressions, lip movements, and gestures. Solves the hardest remaining problem in AI filmmaking: consistent character performance across shots.
Try Act Two
V2V: restyle without re-shooting.
Upload existing video. Describe the new aesthetic. The model produces a new video with the same motion and composition, transformed. Use it for creative reinterpretations, atmosphere shifts (sunny to rainy), and style exploration (photoreal to painterly).
Professional-grade upscaling.
Topaz Video Upscale is the same technology film restorers use. Takes 720p or 1080p footage to 4K without the softness of traditional upscaling. Essential for delivering broadcast-quality output from older or lower-res source material.
Before/after splits.
A workflow preset that produces split-screen comparison videos — renovation before-and-after, colour variant A vs B, with-and-without CGI. Useful for property developers, product designers, and agencies pitching transformation projects.
