-i input.mp4: Specifies the input file.
-vcodec libx264: Uses the H.264 video codec.
-crf 23: Sets the constant rate factor (CRF). Lower values mean better quality. The range is 0-51, where 0 is lossless, 23 is the default, and 51 is the worst quality.
-preset medium: Adjusts the balance between compression speed and file size.
Verify the Compressed Video
After running the command, FFmpeg will process the video and save the compressed version as output.mp4. Check the output video to ensure the quality meets your expectations.
Tips for Better Compression
Choose the right CRF: Experiment with the CRF value to find the best balance between quality and file size.
Use different presets: FFmpeg offers various presets (ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow). Adjusting the preset will impact the encoding time and the efficiency of the compression.
Audio Compression: You can add audio compression to the command if necessary:
