varg character keynote

One varg render produces a 9:16 talking-speaker video: Soul generates the character, Nano Banana 2.1 the empty stage, and Seedance 2.5 puts the character on that stage and voices the line with native audio.

Generation runs on varg: the varg MCP server (https://mcp.varg.ai/mcp, tool render_video) or the varg-ai skill (cloud render, POST /v2/render). Read varg-ai for sign-in, models and the render format.

To create or swap a character, edit ONLY three things

1. LINE: one or two short spoken sentences, emotional hook + payoff (fits 8 s).
2. character prompt: "Candid photo of ..." + body/face/clothing details + "Vivid saturated colors, realistic skin detail." Contrast sells the line: an exact age, an unusual build or a loud outfit played straight beats a generic presenter. The varg-character-design skill has archetypes, realism wording and moderation-safe phrasing; if the speaker must reappear in other videos, make a sheet there and pass its face crop instead of generating with Soul.
3. scene prompt: stage description, always "empty, no people", with a themed screen behind the speaker.

Template (cloud render: no imports)

const LINE = "I learned to code at sixty-eight. Your excuse just expired.";
