I am putting together a video using .MTS and .MOV files. I am also using high resolution .jpeg photos. I am also adding music files. I am using Sony Movie Studio Platinum 12.0 (64bit) on a Windows 7 64Bit, Dell, with 8 Gigs of RAM. I rendered movie as .AVI file and the music was extremely choppy. My goal is to show this video from my laptop, through a HD projector, onto a movie screen. What is the best way to render such a project, and why is my audio choppy? I have never had a problem with audio before.
