See the [[H.264]] and [[AAC]] encoding guides if you are using modern devices. These codecs will offer better compression efficiency; using modern containers like MP4 or MKV is also recommended.

    2424You can select a video quality level with `-qscale:v n` (or the alias `-q:v n`), where ''n'' is a number from 1-31, with 1 being highest quality/largest filesize and 31 being the lowest quality/smallest filesize. This is a variable bit rate mode, roughly analogous to using `-qp` (constant QP [quantization parameter]) with x264. Most of the time this should be the preferred method.
