正向計秒數:
$mod(%playback_time_seconds%,$add($len(%title%),1))
反向計秒數:
$sub($len(%title%),$mod(%playback_time_seconds%,$add($len(%title%),1)))
ex:
$puts(titleLen,$len(%title%))
$substr(%title%,$mod(%playback_time_seconds%,$add($get(titleLen),1)),$get(titleLen))

ex:
$substr(%title%,0,$sub($len(%title%),$mod(%playback_time_seconds%,$add($len(%title%),1))))
