# FFmpeg conversion options:
# -c:v libx264   : Use H.264 video codec for video stream
# -c:a copy      : Copy audio stream without re-encoding
# -vf format=yuv420p : Convert to YUV420P color space (better compatibility)
# -movflags +faststart : Optimize for web streaming by moving metadata to front

# Enable case-insensitive globbing
