Sound
You need a clear choice among room tone, a key sound effect, one line of dialogue, and deliberate near-silence.
- Decide what the sound layer actually needs: a room bed, one key effect, one spoken line, or almost no sound.
- For dialogue, a locked medium close-up, a short line, and less head turning while speaking usually keep lip motion more stable.
- Subtitles, ad copy, and legal text belong in post. Do not expect the model to burn them into the plate reliably.
