Is Seedance better than Runway for music videos?
For dance-focused music videos, yes. Seedance 2 was specifically built for beat-synced choreography and lip-sync, producing rhythmically accurate body motion. For cinematic music videos requiring precise camera work and visual effects, Runway Gen-4's Motion Brush and editing tools are more suitable.
How do the prices compare?
Seedance 2 costs $0.3024/s while Runway Turbo costs $0.05/s and Standard costs $0.12/s. A 10-second clip costs $3.02 on Seedance vs $0.50 on Runway Turbo or $1.20 on Runway Standard. Seedance is 2.5-6x more expensive, with the premium going toward specialized dance and lip-sync capabilities.
Which handles camera motion better?
Runway Gen-4 offers Motion Brush for granular per-region motion control, making it superior for specific camera and object movement. Seedance 2 focuses on body motion and beat sync rather than camera control. For camera-driven cinematic content, Runway is the better tool.
