    The verdict

    When to pick Pika

    Pick Pika in pre-production - concept motion, style tests, and animatic drafts you'll happily throw away.

    When to pick Runway Gen-4.5

    Pick Runway Gen-4.5 in production - when the storyboard is locked and the job is to execute planned shots with precision.
