This is to extract video files to individual frames. When I use 128000 the file size is 60 MB but when I use 320000 the file size is 110 MB. But if you have plenty storage, you can use 320000 for 320kbit/sec. If you has small storage, you can use 128000 for 128kbit/sec option. Note the bitrate is in kbit/s so you use 128000 for 128kbit/sec, etc. This is the command to extract or convert audio to video AND you can set the bitrate too. Video to Audioįfmpeg -i filename.mp4 -b:a 320000 filename.mp3 So by using -qscale 0, the output will not decrease the quality. qscale is a scale from 0 to 10 specifying the output quality from 0 is the best to 10 the worst.

Usually you add output option if you want to convert it to different format, but if you didn’t include it, you will check the file. You can change the filename.mp4 to any file you want to check. This post is to combine all command that I used frequently and for backup too, in case I forgot the command. At first I only use it to convert some MP4 to MP3, but then it can even convert MP4 to every single frame in jpg/png, how great is that, huh? At first I was sceptical by it’s cli design, I’ve heard there were so many great file converter but I stumble upon this when I edit some files with audacity.įFmpeg being a CLI software means I can pull it out everytime I open my terminal (which is 24/7) so I can do quick command to convert file A to file B. It is a tool to convert a file format to different format. Today I met an awesome tool called FFmpeg.
