Frequently Asked Questions

Common questions about Recast character swap

What is Recast Studio? +
Recast Studio is an AI-powered character swap tool on Aura AI. You upload a video and up to 4 reference images of a new subject. The AI replaces the original person or character while preserving the original motion, camera angles, lighting, and audio. Three quality tiers are available: Recast 1 (classic), Recast 3 (standard), and Recast 3 PRO (top quality).
How much does Recast cost? +
Recast uses a token-based system. Recast 1 (classic tier) starts at 4 tokens per generation, Recast 3 (standard) starts at 5 tokens, and Recast 3 PRO (top quality) starts at 7 tokens. Tokens are included with all paid Aura AI plans — Starter, Pro, and Premium.
What video formats and lengths does Recast support? +
Recast accepts common video formats including MP4 and MOV. Videos up to 60 seconds are supported. Videos longer than 10 seconds are automatically split into segments, each segment is processed individually, and the results are merged back into one seamless video.
Are there any limitations to character swap? +
Recast works best when the subject is clearly visible and not heavily occluded. Extreme camera motion or very fast cuts may reduce accuracy. For best results, use 2-4 high-quality reference images showing the replacement subject from different angles. The original audio track is preserved in Recast 3 and Recast 3 PRO tiers.
