RPU after demuxing shorter than videostream

[starcook]

The problem: the RPU is from the same source but not frame-identical with the video stream, it runs faster(?).

In the first minutes everything is synchronous, at about half there is a delay of -8 frames and at the end even -14. The video itself runs at 23.976fps, the DV layer too, but comes to a different length.

The crazy thing: In the source it seems to work anyway. As soon as you demux and inject, it no longer works. The RPU is vanilla from the UHD but still 14 frames shorter than the video stream. How can that be?

I extracted the EL for fun and played with the fps, with 23.97475 it comes to the length of the video stream. Crazy.

Does anyone have any ideas? Is there any way to stretch the RPU? And why the hell is the source running correctly?!

Is your source a retail disc? If it is, what is the title?
Otherwise, it might just be an invalid file.

[starcook]

Yes, it is. Apocalypse Now (US-UHD, Redux). On the disc the DV layer runs fine, but something seems to change when extracting.

Did you get any warning during extraction? I think the RPU is not fully extracted.

[starcook]

No, nothing at all. Everything is running normally. I would understand if the RPU was just truncated, but it covers the entire video stream, just at a different speed.
