Basic FFmpeg Commands for Video Compression

Here are some fundamental commands to get you started:

Compressing a Video

To compress a video file, you can use the following command:

ffmpeg -i input.mp4 -vcodec libx264 -crf 28 output.mp4

This command uses the libx264 codec and sets the Constant Rate Factor (CRF) to 28, which balances quality and file size.

Changing Video Format

To convert a video to another format, use:

ffmpeg -i input.avi output.mp4

Adjusting Video Bitrate

You can specify the video bitrate with:

ffmpeg -i input.mp4 -b:v 1000k output.mp4

Advanced Compression Techniques

Multi-pass Encoding

Multi-pass encoding improves quality at lower bitrates:

ffmpeg -y -i input.mp4 -c:v libx264 -b:v 1000k -pass 1 -f mp4 /dev/null && ffmpeg -i input.mp4 -c:v libx264 -b:v 1000k -pass 2 output.mp4

Audio Compression

Don’t forget about audio! Compress audio streams using:

ffmpeg -i input.mp4 -c:a aac -b:a 128k output.mp4

Optimizing Videos for Different Platforms

Depending on your target platform, you may need specific settings:

Troubleshooting Common Issues

Here are some common issues and their solutions:

• FFmpeg not recognized: Ensure the PATH is set correctly.
• Output file too large: Adjust the CRF or bitrate settings.
• Quality loss: Experiment with different codecs and settings.

Conclusion

FFmpeg is a powerful tool for video compression that can help you significantly reduce file sizes while maintaining quality. By mastering FFmpeg commands and techniques, you can streamline your video workflow and enhance your content's accessibility.
