Direct your AI actor's emotion and tone precisely
Tell your AI actor exactly how to feel. Set emotion, energy level, and per-segment tone so your ad creates the exact psychological response you're designing for.
The difference between an ad that converts and one that doesn't is often emotional calibration. The right emotion delivered at the right moment — concern that builds urgency, excitement that creates desire, calm authority that establishes trust — is what separates high-ROAS creative from content that gets scrolled past. BasedUGC's Emotion Control tool gives you precise control over the emotional performance of your AI actor, so you can design the psychological arc of your ad deliberately rather than hoping for a good take.
Set your primary emotion from ten distinct options: excited, calm, concerned, joyful, surprised, empathetic, serious, playful, authoritative, and confident. Combine with an energy level parameter (low, medium, high) and optional per-segment emotion changes for ads that shift tone throughout their runtime. The AI adjusts vocal tone, speech pacing, facial expression, and micro-expressions throughout the video — not just the face, but the complete performance, so the emotional calibration feels coherent and authentic rather than cosmetically applied.
How it works
Create any UGC video with your chosen actor and script. Emotion Control can be set at initial generation or applied as a regeneration parameter to an existing video.
Choose your primary emotion (excited, calm, concerned, joyful, and more) and energy level (low, medium, high). Set different emotions per script segment for ads that shift tone.
AI applies the emotion profile to the actor's vocal delivery, facial expression, and body language simultaneously. Review the output and fine-tune if needed.

FAQ
BasedUGC Emotion Control supports ten primary emotions: Excited (high energy, enthusiastic delivery), Calm (measured, reassuring, grounded), Concerned (empathetic urgency, problem-aware), Joyful (warm, happiness-forward, positive), Surprised (genuine reaction, discovery-moment energy), Empathetic (understanding, validation-forward), Serious (authoritative, factual), Playful (light, fun, spontaneous), Authoritative (confident expertise, trust-building), and Confident (self-assured, direct). Each emotion is combined with an energy level modifier (Low, Medium, High) that adjusts intensity without changing the underlying emotional quality — Low Excited is warm and happy; High Excited is near-euphoric.
Yes. You can define different emotion parameters for different segments of your script using the per-segment emotion editor. Many of the highest-converting ad formats rely on emotional shifts throughout the video. A common pattern: open with Concerned at Medium energy to establish the problem, shift to Serious at Low energy for the solution introduction, then close with Excited at High energy for the product reveal and CTA. Transitions between emotion segments are rendered naturally — the AI actor's expression and vocal tone shift smoothly between segments rather than cutting abruptly between completely different emotional registers.
Both — and this is what distinguishes BasedUGC's Emotion Control from simpler face expression tools. Our model adjusts all components of the actor's performance simultaneously: vocal pitch (higher for excited, lower for calm and authoritative), speech rate (faster for excited and urgent, slower for empathetic and serious), emphasis patterns on key words, facial expression including brow position and eye openness, head movement amplitude, and body language where visible in frame. The result is a coherent emotional performance rather than a neutral speech delivery with a different facial expression cosmetically mapped on top of it.
Emotional contagion is a well-documented psychological phenomenon — viewers unconsciously mirror the emotional state of people they observe on screen. An AI actor delivering a script in a flat, emotionally neutral way produces a flat emotional response in the viewer, which doesn't prime them for action. An actor delivering the same script with precisely calibrated urgency, enthusiasm, or empathy creates the corresponding emotional state in the viewer — which is exactly the psychological precondition you need for your CTA to land. Performance marketers who test identical scripts with different emotion parameters consistently see ROAS differences of 20-40%.
