HD100 - music Video
 
hi guys
i'm shooting CG 3d Music Video, and i will post it when it'll be finished
i need some advice on Hd100
1. if i want to shoot 720 - 30p and then slow it down to 25p , how much i have to speed up my Song in precent for matching when it'll playback in 25f timeline .


2.as i read the forum if i want to shoot HDV-SD 50p
i have to speed up my song about 50% (on 25 timeline)
does it means that if it's 100BPM , i have to playback song at 150BPM ?

3.what about 60p ? how much faster in 25f timeline ?

thanks

29.97/25 = 1.1988, so play back the footage 19.88% faster on set for sync.

No, you have to double your playback speed. 200bpm.
