    如何选择?

    以下场景推荐 Runway Gen-4

    • •Agencies producing premium ad and brand films end-to-end
    • •Editorial teams that want a single tool for shot, motion, and finishing
    • •Studios needing reliable character continuity across cuts
    +Cross-shot character consistency that rivals dedicated identity-anchor systems
    +Industry-leading motion brush, camera control, and act-one capture tooling
    +Strongest enterprise API + SLAs of any creator-facing video platform
    −Credit consumption climbs fast on 4K and longer outputs
    −Native audio still trails Veo 3 / Veo 3.1 on dialogue-heavy shots
    −Closed proprietary stack — no model swap per shot

    以下场景推荐 Synthesia

    • •Learning & Development teams producing onboarding and training video at scale
    • •Internal comms and HR video that needs to ship in many languages
    • •Sales and customer-success teams personalizing outreach video
    +Largest stock avatar library and the most natural multilingual voices in the category
    +Enterprise-grade brand controls, version history, SOC2, and approval workflows
    +Translates and re-dubs existing video into 160+ languages in minutes
    −Limited to avatar-led video — cinematic motion, product shots, and ads need a different tool
    −Pricing scales steeply once you need custom avatars or higher volume
    −Less prompt control than text-to-video models — the avatar is the focal point
