View Full Version : there's more than one way to split a movie

couldn't find a good place to put this so here goes. i've mostly made short 1CD movies and am happy with those, but one day i'm going to want to rip longer ones.

from what i can make out, most people make a file twice the size of the media and then cut it in half (or half to the nearest i-frame).

am i the only person who thinks, when watching said movies with non-techies, and when the disc change happens in the middle of someone's line, that this looks rather unprofessional, even slightly spoils the movie?

what i was thinking was, would it not be better to split at the nearest chapter stop. however, i still want to use the full storage space. so one part will have a slightly higher bitrate than the other. i don't see this being a major problem unless the movie has really long chapters (like Magnolia, 15 mins). Of course, it's easy to get the time you want to split at, and it's easy to convert that into frames. But beyond that, i haven't really thought it through.

Anyone tried this/got any advice? thanks a lot.

Sort of makes you ponder, in the IFO, if chapter timestamps are referenced to the pulled framerate (29.97) or the film (23.976), because obviously 4:56 @ 29.97 yields a different frame number than 4:56 @ 23.976.

And if they are referenced to the pulled down framerate, you'll need to take this into account :)

I normally use avisplit and set it to halfsplit (size) mode. After it calculates the size and time, I load up nandub and see where in the movie this occurs and adjust either forward or back to get a good split point. A little more work but at least its not splitting in mid sentence.
