Hello all,
I've been watching CCE Working Method tread since the beginning, and the whole time playing around with the CCE method whenever I could. However, it seems that no one has yet explained why it would be impossible to mux a CCE stream into the original VOB without reauthoring. I'm sure that I'm not the only one here with this problem, but as a poor college student, going out and buying DVDMaestro and Scenarist is not exactly an option :(. So the only way that I can use CCE, is if it can be done without reauthoring. This fact aside, a method without reauthoring would require much less time and complexity.
So here was my experiment: Rip one of my movies, re-encode with CCE, pulldown the resultant mpv to change the framerate back to 29.97, and re-mux the final product directly into the VOBs with IFO edit.
The result: a working movie with wrong chapter points.
Please correct me where I am wrong, as I know very little about DVD structure, but here are some conclusions that I've made:
Since the chapter points grow progressively farther ahead in the movie than where they should be, it would seem that they reference a file position within the VOBs. Since your CCE output is smaller than the original, the chapter points occur too early. But is this relationship linear (or can a relationship be determined)?
If so, then why couldn't IFOEdit scale the chapter points based on the size difference between the original and the CCE re-encoded movie, and then place each point at the nearest I frame to the proportional location?
The result would be an IFOEdit that can handle CCE video and REMPEG video identically from an end user's perspective. The chapter points will not be exact, but they will be very close, which is just fine for 99.9% of applications. If anyone can pull this off its Derrow, and I'd really like to hear some comments as to the feasibility of this approach.
