# Script to convert videos (mainly .mov) to .mp4 with efficient compression
# Usage: ./video.sh /path/to/video.mov
# ./video.sh "/Users/velrino/Documents/screenshots/Screen Recording 2025-11-24 at 15.58.38.mov"
# This script will:
# - Convert video to H.264/AAC MP4 format
# - Compress the file efficiently while maintaining good quality
# - Save the output to ~/Documents/videos-ffmpeg/
#
# Requirements: ffmpeg (install with: brew install ffmpeg)
