![]() If it's half hour videos, they'll probably be done in around 30-45 seconds, hour long videos might maybe a minute or two, and movie-length videos would be anywhere from two to four minutes.Īs for batch converting, there are two ways. I've never used it and I pretty much do exactly what you're doing here almost every day.Įither way, the above command will literally only take probably around 30 seconds to a minute depending on the length of the video and the bitrate you've chosen. I'm not certain the -map 0 parameter is necessary either, but I might be wrong. ![]() If you just want the audio converted, the command should be:įfmpeg -i /media/directory_A/inputC.mkv -c:v copy -c:a aac -map 0 /media/directory_B/ouputD.mkvĪlso, the AAC encoder defaults to 128kbits, so you might want to add -b:a 320k after aac (or really any higher bitrate since 128k isn't really the greatest of quality, even 160k is generally fine, though the audiophiles will all hate me for saying that).įfmpeg -i /media/directory_A/inputC.mkv -c:v copy -c:a aac -b:a 320k -map 0 /media/directory_B/ouputD.mkv ![]() Do you just want to convert the audio? Because that command is converting your video as well, which might be why it's taking so long.
