Hardware Requirements & Performance

To produce a 5-second video at 25 FPS with 480p resolution, you need at least 18 GB of VRAM. A 'quantized' version may be available in the future for lower VRAM usage.

Generation Quality

Lip-sync results using StableAvatar can be 'hit or miss.' Occasionally, lip movements are inaccurate, and facial expressions may appear exaggerated compared to other AI tools.

StableAvatar's Unique Advantage

Compared to other tools, StableAvatar is capable of synchronizing hand movements with high precision, such as strumming guitar strings or pressing piano keys according to the musical chords in the audio.
