Operator guidance
The only Runway model for video-to-video workflows. At $0.28/s (28 credits × $0.01, 56-credit minimum) with up to 30s input, choose aleph2 when you have an existing video clip to modify rather than generating from scratch. For new video generation: gen4.5 ($0.12/s, T2V+I2V) or gen4_turbo ($0.05/s, I2V only). The keyframe guidance system can steer content at specific timestamps; outpainting expands the aspect ratio of the input clip.
Use cases
- Prompt-driven style re-rendering of existing video footage
- Keyframe-guided retiming and content modification
- Outpainting existing video to a new aspect ratio
- Video editing workflows where the output must reference an existing clip
Limitations
- Video-to-video only — requires an existing video clip as input
- No mask-guided inpainting or element/background replacement
- 56-credit minimum per call (≈2s minimum at 28cr/s)
- No native audio
- references[] parameter from predecessor gen4_aleph not available on aleph2
