arrow_forwardFrequently Asked Questions
Is Luma Ray2 a good alternative to Runway?
Yes, but they serve different strengths. At 720p, Luma costs $0.20/s vs Runway's $0.05/s (Turbo) or $0.12/s (Standard). Luma is pricier per second at matching resolution, but offers 20+ camera presets and the ability to extend clips to 30 seconds. Runway counters with Motion Brush and a more mature editing suite.
What makes Luma different from Runway?
Luma Ray2's key differentiators are 20+ built-in camera presets for cinematic movement, three resolution tiers (540p/720p/1080p), and extend-to-30s clip extension. Runway Gen-4's edge is Motion Brush for frame-level control over specific regions, plus a comprehensive creative editing toolkit built over several years.
How do the prices compare at similar quality?
At 720p, Luma costs $0.20/s vs Runway Turbo at $0.05/s or Standard at $0.12/s. Luma is 67% more expensive than Runway Standard and 4x the cost of Turbo at the same resolution. Luma's premium is justified if you need its camera presets or the ability to extend clips to 30 seconds.
