Arcads offers several models to animate digital actors, each designed for different inputs, levels of realism, and video lengths. Depending on whether you’re working from audio, an image, or a full script, some models will be better suited than others.

Below is a quick overview to help you understand when to use Omnihuman 1.5, Audio-Driven, or Arcads 1.0.
Omnihuman 1.5:
Omnihuman 1.5 animates a static image.
Result: a talking, animated face
Style: Expressive, with stronger facial movements and emotions
Perceived as: slightly more AI-styled (this is subjective — some users prefer this look)
400 characters max
The actor remains static (no body or camera movement)
Audio-Driven
Audio-Driven works the same way as Omni Human: it animates an image but based on an audio input.
Result: realistic talking face animation
Style: Lipsync is generally perceived as more natural / realistic than Omnihuman 1.5 (subjective)
600 characters max
The actor remains static (no body or camera movement)
Arcads 1.0
Arcads 1.0 generates a video from a text script, using a digital actor that speaks and moves.
Result: a stable, animated actor with consistent movement
Best for: Stable for longer videos (education, demos, narratives)
1500 characters max
The actor follows a predefined movement, making the video more dynamic while remaining visually stable.
Which one should I use?
Use Omnihuman 1.5 for expressive videos
Use Audio-Driven if you want a better lipsync
Use Arcads 1.0 if you want longer videos with scripted content and stable actor movement.
Each method serves a different purpose — choosing the right one depends on your content, duration, and desired level of realism.
