Re: [dvd::rip] ripping stops short, incorrect framerate is the problem

Has any more been said about this?

I also have several NTSC codec films that are actually 23.976fps FILM coded, this gets reported as 29.970fps and then i get the ripping stopped short errors.

I am unable to do any processing after this.

I'm using latest 0.97.13 dvd::rip

thanks

Hi Ben,

first thanks for this posting. Your thoughts are very interesting and I
think they can help a lot getting rid of this "ripping short" error 
message.

Are you really sure you that you have loss of quality here? I think the
problem with this framerate confusion is, that libdvdread simply reports
the wrong framerate (23.976), which is wrong in the DVD IFO structure. 
dvd::rip probes the VOB data after ripping and detects the correct 
framerate (29.97). Erroneously it says ripping stopped short, because 
the frame count in the IFO is wrong as well. But dvd::rip corrects the 
frame count accordingly, so further processing should work without 
problems.

I don't think you loose any quality here, because during ripping no 
frames are dropped or something like that. Ripping is a somewhat "dumb"
process, no frame decoding is done, no audio sync stuff or something 
sophisticated, where frames could be dropped. All this applies during 
transcoding, but not when the data is copied to the harddisk.

What dvd::rip should do is stop reporting about a short rip, if the 
frame rate was adjusted *and* the frame count changed accordingly (more
or less). What do you think?
