Yes! Sonix offers extensive styling options including font family, size, color, background color, opacity, and position (top, middle, bottom). Preview your style in real-time before rendering.

Sonix preserves your original video quality during the burn-in process. We use high-quality rendering to ensure subtitles look crisp and professional without degrading your footage.

Processing time depends on video length and resolution. A typical 10-minute 1080p video takes about 5-10 minutes to render. You'll receive an email notification when your video is ready.

Sonix exports burned-in videos as MP4 files with H.264 encoding—the most universally compatible video format. Your video will play on virtually any device or platform.
