video projector

Hi, when i layer a video projection over my laser, the masking of the video is delayed behind the laser. If anyone knows how to fix this problem, please let me know, thanks! -@

Hi, I saw a laser show on youtube where the laser show was layered with a video from a projector. I am wondering if this is possible to do in the Beyond program. If so, please link me to a tutorial or explain how to do so. Thank you!
