Thanks i will try next time. After i made this I also plan on shooting more pictures for a smoother video. The only problem i have is that the STF has chromatic aberrations when the contrast between dark en light is high and i had to correct every picture one by one. I tried lightroom 4 but i can't get it to work properly for this kind of CA :(. Maybe video is more simple, oh well the more you do it the more you learn.
