One night after work I got into the IMAX's booth [Wink] and noticed that their splicers cut jagged, and the splicing tape only covered up the part of the film that was cut, like 1.5 or 2 frames. Is there a reason IMAX uses it and regular theaters don't?

I was thinking about the fact that they do 70mm and 3d stuff and megaplexes are running 35mm

I read elsewhere on Film-Tech that the reason for the jagged splice is so that when it comes to any type of bend running through the equipment that it won't snap in two. 70mm travels through much faster when it's running so it needs to keep an ideal flex to it. I think the info was under the "Large Format" forum.

See this thread for some basics. See this post and the one following it for an explanation of the serrated splice.

Yeah Jeremy, I didn't even notice that, but you're right.

Brad's right too, when I worked at Glenn Lakes 8, they had a few 70mm splicers but they were not serrated. And I've seen quite a few bad splices where the film will bend either way at the splice. I also understand that it shouldn't happen in the first place, but with kids in high school running booth would this not be beneficial?
