Explanation:
* ffmpeg -i input.mp4: Specifies your input 4K 2GB video file. Replace input.mp4 with the actual filename.
* -vf scale=1280:720: Scales the video to 720p resolution (1280 pixels wide by 720 pixels high).
* -c:v libx264: Uses the H.264 video codec for efficient compression.
* -preset medium: Sets the encoding speed/quality balance. You can experiment with slow for potentially better compression at the cost of longer encoding time.
* -crf 23: Sets the Constant Rate Factor for quality. Lower values (e.g., 20) give higher quality but larger files, while higher values (e.g., 25) give smaller files but potentially lower quality. Adjust this based on your needs.
* -c:a aac: Uses the AAC audio codec.
* -b:a 128k: Sets the audio bitrate to 128 kbps. This is a common bitrate for web audio.
* output_720p.mp4: Specifies the name of the output 720p video file. You can change this to your desired name.
