# Lessons Learned
|
|
Back to [[Video Stack - Overview]]
|
|
|
|
- A Kokoro-made reference makes Chatterbox clones flat with odd pauses. Use a real human reference (the user's recording worked well; leave more headroom, it peaked at -0.1 dBFS).
|
|
- Generate one sentence at a time (best of several seeds, ~200 ms gaps) to avoid strange pauses.
|
|
- Copywriting: short spoken sentences, numbers written as spoken words, ~105 words per 45 s, leave ~2 s spare. Number-heavy long lines made Prop 1 sound awkward.
|
|
- Gemini reads directions aloud unless they go in the style field.
|
|
- Music must add feel: civic_tension and piano B were rejected; option A (dark low strings, slow heartbeat pulse) chosen for Prop 1. If code-composed music misses twice, use a richer generator.
|
|
- ElevenLabs free tier was blocked for TTS ("unusual activity"); not retried.
|
|
- HyperFrames is easier for local models than Remotion (plain HTML per scene).
|
|
- Pick an authoritative male voice for political ads.
