- Blurred Background: Duplicates video stream, blurs the background to fill 1080×1920, and overlays the original in center.
- Fit (Letterbox): Maintains full aspect ratio and pads margins with black bars.
Configurable Clip Durations
Supports preset YouTube Shorts durations with sub-second accuracy:
Viral Subtitle Engine
Automatic speech-to-text transcription with Advanced SubStation Alpha (.ass) subtitle burn-in. Choose between Classic White, Bold Viral Yellow, and Opaque Subtitle Box styling for maximum engagement.
Async Processing & Celery Architecture
Video probing, encoding, and thumbnail generation run inside isolated background workers, providing real-time job progress polling without blocking web requests.
Security & Compliance First
Subprocess argument array execution prevents shell injection; FFprobe validation blocks corrupted or malicious media; quota enforcement prevents storage exhaustion; rate limiting prevents abuse; security headers protect against XSS, clickjacking, and MIME attacks.
