How to compress videos with FFmpeg?
The basic FFmpeg command to compress a video while preserving the original audio channels looks like this:
ffmpeg -i input.mp4 -c:v libx264 -crf 28 -c:a copy output.mp4
Let's break this down:
ffmpeg
: This calls the FFmpeg tool.-i input.mp4
: Specifies the input video file.-c:v libx264
: Sets the video codec to H.264 (which is very efficient).-crf 28
: The Constant Rate Factor value, which controls the compression level for video. Lower values mean better quality but larger files. 28 is a reasonable default for a good balance of size and quality.-c:a copy
: This flag tells FFmpeg to copy the audio stream from the input to the output without re-encoding it, preserving the original audio channels and quality.output.mp4
: The path and filename for the compressed output video.
You can adjust the -crf
value to get higher compression (worse quality) or lower compression (better quality). Values typically range from 18 (best quality) to 28 (smaller file size).
