Runway Gen-4 and Gen-4 Turbo covering speed and quality as separate priorities is the model selection framework worth understanding
Gen-4 Turbo being the fastest for video generation is the throughput option for iterative creative work where you need to see many directions quickly. Gen-4 being the quality option for outputs you are taking to production is the quality option for final renders where generation speed matters less than output quality.
The practical workflow being to iterate with Turbo to find the right creative direction and then render the final version in Gen-4 is the cost-efficiency approach that applies to most professional creative workflows where exploration and production are distinct phases.
The Character Reference feature for consistent human subjects across multiple generations being highlighted as a new feature addresses the consistency problem that limits multi-clip video production. A recognisable character who looks the same across every clip in a series is what makes narrative AI video possible rather than just impressive collections of individual clips.
The Storyboard feature for planning shot sequences before generating individual clips is the pre-production discipline that produces more coherent multi-clip results by establishing visual and narrative continuity constraints before any generation begins.
Are you using Gen-4 versus Gen-4 Turbo as a deliberate speed-quality tradeoff or defaulting to one for everything?
