Step 1: Download FFmpeg for Windows. Visit the FFmpeg download page. And I learned that 2 Pass encoding will do the job better. And this is the command line that I am using to encode videos with 2 pass. ffmpeg -i input.mkv -c:v libx264 -vf "scale=1920x1080" -vb 3.5M -pass 1 -an pass1.mp4. ffmpeg -i input.mkv -c:v libx264 -vf "scale=1920x1080" -vb 3.5M -pass 2 -c:a copy pass2.mp4. And this works fine.6. -c or -codec is a generic stream selector, so you can use it to set the codec for any of the streams be they audio or video. -acodec:1 is the same as -codec:a:1 and indicates you are setting the codec for the second audio stream (the first audio stream is 0). from your linked documentation: -c, -codec.
