 Simple default conversion:
 ffmpeg -i {input} {output}
 
 Specify codecs:
 -c:v {vcodec} -c:a {acodec}

 Scale the video:
 -s {horz}x{vert}
 
 Specify rates:
 -r:a {audio rate} -b:v {video bitrate} -b:a {audio bitrate}
 
 Or even better, use CRF with 26x:

 Change duration:
 -ss {hrs}:{mins}:{secs}.{msecs} -t {hrs}:{mins}:{secs}.{msecs}
 
 Fun audio + image mix:
