Seedance 2.0 Valence-Arousal FACS
Created an example scene to show how valence-arousal and FACS can be used together.
Prompt:
15s, cinematic emotional confrontation.
Two characters @[chracter sheet ref] stand face-to-face inside a small apartment kitchen late at night. The room is dimly lit by a single warm overhead light and soft city lights leaking through the window. The atmosphere feels emotionally exhausted, tense and painfully intimate, like an argument that has been building for years.
Modern cinematic realism, subtle handheld camera movement, shallow depth of field, soft film grain, emotionally restrained acting, realistic silence between dialogue lines.
Beat 1:
The emotional state remains at high arousal and medium-low valence.
Camera:
slow handheld side shot circling both characters
tight over-the-shoulder close-ups
brief eye-level two-shot showing emotional distance
FACS Character A:
AU4 AU7 AU17
Dialogue A:
/juː ˈnev.ɚ ˈriː.ə .li lʊkt æt miː/
/juː wɚ ɔːlˌweɪz ˈsʌmˌwɛɹ ɛls/
Voice:
tight restrained voice, controlled anger, uneven breathing
Character A tries to stay calm while suppressing years of resentment.
Beat 2:
The emotional state gradually shifts toward very low valence and medium-high arousal.
Camera:
slow push-in toward Character B
extreme close-up on trembling eyes and mouth
wide static shot showing silence after the argument peaks
FACS Character B:
AU1 AU4 AU15 AU25
Dialogue B:
/aɪ wəz ˈtɹaɪ.ɪŋ maɪ bɛst/
/aɪ dɪdnt noʊ haʊ tə fɪks ˈɛv.ɹiˌθɪŋ/
Voice:
breaking voice, unstable breath support, emotionally collapsing delivery
Beat 3:
The emotional state remains at very low valence and medium-low arousal.
Camera:
locked wide shot with silence between them
slow close-up on both characters avoiding eye contact
subtle rack focus between faces
FACS Character A:
AU1 AU15 AU17
Dialogue A:
/ˈmeɪ.bi wiː stɑpt ˈlɪs.ən.ɪŋ ə lɔŋ taɪm əˈgoʊ/
Voice:
emotionally exhausted, quieter delivery, fading anger replaced by sadness
No exaggerated screaming, no violence, no comedy, no text overlay, no watermark.
Seedance 2.0 Emotional Coordinates
Meet Valence-Arousal.
I’ve been experimenting with valence-arousal prompting in Seedance 2.0 on
@mitte_ai, and surprisingly, a lot of it actually works. Most likely this should transfer to many other video/image models too.
Before we start, I should mention that a lot of attempts can hit safety/violence filters depending on how extreme the emotional state becomes. My test prompts were also intentionally very simple and open-ended, which probably increased that.
Valence measures how positive or negative an emotional state is.
Arousal measures how calm or activated it is.
So instead of writing:
“sad, anxious, emotionally overwhelmed”
you can try things like:
valence: low
arousal: high
I tested mostly numeric values at first, but honestly I’ve been getting much better and more stable results with transition-based prompting like this:
“The emotional state gradually shifts from high valence and low arousal to low valence and high arousal.”
That feels much more model-friendly right now.
I think this could become really useful for subtle acting, emotional transitions, cinematic dialogue scenes, uncanny performances and mood-driven storytelling.
