FAQ
🎵 Why is audio more reliable now?
MediaElementSource created once. AudioContext is not destroyed, only suspended. This respects Web Audio spec and works on mobile.
📺 What resolution and bitrate?
Full original resolution. Bitrate adapts: 40 Mbps for 4K, 12 Mbps for lower. High quality.
🎨 How does drift-free sync work?
Uses requestVideoFrameCallback (frame-accurate) with fallback to setTimeout based on video framerate. No visual desync.
⏱️ Export takes time?
Real-time processing. Progress bar shows exact percentage. A 1‑minute video takes about 1 minute.
