Encoding DVDs with MEncoder
Here is an example on how to encode a DVD using MEncoder.
You can get hints for the audio id, supported languages, aspect ratio, and other values by playing the DVD with mplayer dvd://1 and inspecting the resulting console output.
- dvd://1: read the main track of the DVD. Sometimes the main video is on another track (e.g. dvd://3, dvd://5, dvd://81, ...).
- -o test.avi: selects the output file and AVI as container format. You could also specify an MP4 file here.
- -ss 120 -endpos 10: this tells the encoder to skip the first 120 seconds and then stop after encoding 10 seconds of video. This is used initially to test on a small representative part of the video that the encoding options are correct. Afterwards you can drop these options.
- -alang en: choose the English audio track.
- -slang en: add the English subtitles to the video.
- -aid 130: choose the audio track with id 130. Specifying this is not necessary in most cases.
- -psprobe 1000000: use this option to force MEncoder to extend the search for the audio stream. Only necessary if MEncoder says no audio stream found.
- -vf crop=720:446:0:66: you can use this to crop of black borders.
- -aspect 1.78: often it is necessary to set the pixel aspect ratio of the output video.
- -af volume=15: with many DVDs it is necessary to boost the audio volume.
- -ovc x264 -x264encopts crf=21:threads=2: this selects the H.264 video encoder and configures it.
- -oac mp3lame -lameopts q=2: this selects the MP3 audio encoder and configures it. You can also use -oac faac -faacopts quality=300 if you prefer to use the AAC codec.
Once you have found the right options, rerun the command without the -ss and -endpos option to encode the full video.
