- Remotion, timed from the voice-over's word timestamps. Never hard-coded seconds. One timeline renders 16:9, 9:16 and the cover.
- Gates: script (my edits shown as a diff) → 6 to 8 voice test lines → voice-over → music → stills contact sheet → render → check the last frames.
- Only the voice costs money. Music comes from free libraries (Mixkit), footage is code or free stock. A video costs up to $1; above $10 needs an OK.
- Mix by meter: voice at −14 LUFS, music 18 to 26 dB under it, then
loudnorm. - One sentence is one slide. Change the visual every 1 to 1.5 seconds. Caption only the key words.
- Render on a GPU PC over Tailscale. It's about 8× faster than the server.

How I make launch films and reels with agents: Remotion, voice-over timestamps, free music, measured mix.
