So I'm making a light saber video in which i mask mediagenerator to create a light saber effect. I shot the video on canon hv30 in 24p format. When I go to render to either mpg of wmv the mask is shifter "not in sync with my original video" When I choose Avi or mp4 this problem does not happen. Anyone know why my mask seems to be in different position when I render to differnt formats. When I play it back it on the timeline it looks right, the problem only happens when i go to render In 24 p format.
