What it does in the AI content pipeline

HeyGen replaces the creator’s physical recording. The pipeline: 11 Labs voice clone generates audio in 45-60 second chunks → HeyGen Avatar 5 lip-syncs the avatar to the audio → Claude Code stitches chunks and adds HyperFrames motion graphics. A 5-hour manual production pipeline becomes an overnight automated job. ^[012]
