Frequently Asked Questions
How does Sync compare to HeyGen or Synthesia?
While HeyGen and Synthesia focus on AI avatar generation with lip sync as a feature, Sync specializes exclusively in lip synchronization. This makes Sync superior for working with existing video content, offering more natural results and broader language support at a lower cost.
What video formats does Sync support?
Sync supports all major video formats including MP4, MOV, AVI, and WebM. It can process videos up to 4K resolution, though processing time and costs increase with higher resolutions and longer durations.
