FrontEnd:

• "timming" : dictionary
  • start: start time (miliseconds unit, elapse from the sing begin)of the background (the background could be image/video
  • duration: duration of the backround caculated from start time (in miliseconds unit) Backend: ffmpeg:

-ss [time] => convert timing.start => hh:mm:ss.xxx => string with flag -ss

-t [duration] => convert timming.duration => hh:mm:ss.mmm to express duration of background. mean duration = timing.start + timming.duration => convert to hh:mm:ss.xxx
