thanks guys,and the lag in the video is because my pc run toribash on max at 15-20fps,so i record in slow mo,but the speed-up in the program don't work really good.
also,im practicing the pan-crop,started 4 days ago i guess.
the problem of no-sync is because the song don't have really a good BpS rate,so is really hard to think what to do in that time.
thanks too.
until now this is my best edit:
