OmniHuman 1.5 Lip Sync in Promptus

Quick answer: OmniHuman 1.5 is a lip-sync and character-animation model available in Promptus, focused on realistic multi-character video with synchronized speech, gesture, and expression. Watch the full tutorial below.

OmniHuman 1.5 is built for turning text prompts into cinematic, performance-style video rather than a single static talking-head clip — the tutorial demonstrates duet-style scenes with more than one character interacting on screen.

What the tutorial covers

• Duet realism — multi-character coordination and natural interaction between two subjects in the same scene
• Gesture and expression control — directing body language and facial expression alongside the lip-synced speech
• Creator and educator use cases — where multi-character, presenter-style video fits (tutorials, product walkthroughs, narrated content)

The workflow runs inside Promptus rather than requiring a separate hosted tool — the video below walks through setup and a full generation from prompt to finished clip.
