Industry background

• Digital broadcasting has moved from "like a person" to "being that person": role consistency and behavioral imitation have become the key to differentiation.
• AI video marketing has moved from single production to batch, multi-language, and editable large-scale pipelines.

Impact Analysis

• Content production costs have dropped significantly: Mass production of oral/training/marketing videos without studios and actors.
• Multi-language localization becomes a growth lever: One-click translation + lip synchronization allows one material to cover the global market.
• Supervision and trust are tightened simultaneously: Real-name verification and AI-generated annotations (such as the requirements of the EU AI Act) have become standard features of the platform.

Practical Advice

• Marketing team: First verify the ROI of small-batch oral broadcasting and multi-language translation, and then scale it up.
• Enterprise procurement: Incorporate real-name verification, content review, and data compliance into hard selection indicators.
• Creators: Prioritize using free credits to test HeyGen / Synthesia, and compare lip synchronization and character consistency before subscribing (pricing is subject to the official real-time page).
