Pulldown flags in 29.97 m2v

[feliz]

After spending hours trying to encode Man on Fire, I have found that the .m2v file is 29.97 fps and the pulldown flag was set. When loading the vobs or m2v file into dgindex the timestamp report 2:26 duration instead of 1:56 in the ifo. (counting the extra frames created by the flags into the total duration) I think that dvd rebuilder was using the flags to create extra frames(jerky video) and causing a recurrent error with cce and rebuilding.

If I do it manually setting dgindex to raw frames (ignoring the flags) and decombing thru a avs file to 24.97fps. I can recode in CCE without any problems.

Is there a way that dvd rebuilder handles the pulldown flags or a way to ignore the flags?

Actually DVD-RB records the flags during PREPARE and reapplies them exactly frame-by-frame during rebuild.

In other words, I think you are mistaken, or someone was playing with the settings.

the V01.d2v file in then d2avs folder report a 23.97 fps, when I'm sure the d2v file should be 29.97. That what dgindex with raw frame reports. This is the d2v file which I have been successful with. Is ther another flag? I'm using dgdecode.dll and .83. The field operation is set to none, when I did it my self I used raw frames in field operation (3).

All default setting in dvd-rebuilder

Which with ingnoring the flags gives more frames?

Using the vobs only .d2v by dvd rebuilder:

Same vob's differ fps?

There you go... you're making incorrect assumptions... do NOT change anything and DVD-RB will work fine.

It is supposed to be 23.976. All DVD-RB encoding on NTSC sources is done at a fixed framerate of 23.976. It is a common denominator and is done that way in order to handle mixed (hybrid) sources. It gets reset to the proper framerate on REBUILD.

And please don't anybody reading this start talking nonsense about frame loss or progressive conversion or "forced frame" output... If you are thinking in those terms you are in way over your head. I've explained this before and won't do it again. There is no frame loss -- the data is fed as raw frames. It works and is in fact the only method of encoding to date that will correctly reproduce progressive, interlaced, and hybrid formats 100% exactly in the same format as the original.
