Fix Silent Phone Call Scenes in AI-Generated Video

How to fix phone call conversation scenes in AI-generated videos: attach the instruction below to your existing video-generation prompt and run it through ChatGPT first. Then copy the refined prompt ChatGPT gives back and use it to generate the video. This keeps the on-screen character completely silent while the dialogue comes only from the person on the other end of the call. "Instruction: The onscreen character only listens. Keep their mouth and jaw completely still, no speaking, mouthing, lip-sync, or speech animation. All dialogue must come exclusively from the off-screen caller through the phone."
