Quote from ffmpeg docs: "The range of the CRF scale is 0–51, where 0 is lossless, 23 is the default, and 51 is worst quality possible. A lower value generally leads to higher quality, and a subjectively sane range is 17–28. Consider 17 or 18 to be visually lossless or nearly so." 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.
