BTW: BD-RB will do what you said it won't (remove the pulldown flags and keep intact)... you just have to make sure you use the proper settings. I've mentioned numerous times in this thread that 720x480@23.976fps isn't a part of the standard -- but is supported by every player so I allow it. In fact, since you said "...and then ran it through BDRB. BDRB left it alone.", I guess that is self evident. Of course, on most players you can leave the pulldown flags in and the player has the ability to playback at the original FILM rate anyway. I'll download your sources and check it out. I think I may know what change I made that caused BD-RB to misinterpret the source aspect on your 720x480 source. Not sure though. The file import module (especially for 720x480) has become really convoluted from all the "adjustments" I have made for the stupid things people do when they reencode and post video files. I just ran into one the other day where someone wanted to keep a 4:3 source at a standard 720x480 resolution -- so they resized the picture to 640x480 and added black borders. Tell me how I'm supposed to adjust for that... Last edited by jdobbs; 14th October 2018 at 14:50. |

Doesn't help when trying to mix DVD content with MKV content, i.e., "Video Files."
That said, the way some DVDs get authored results in a piece of video that you want being contained within a multi-part VOB. Hence the use of DVDFab to extract content based upon the "title." This particular DVD had the special features in their only VOB. Can't count on that with every DVD. |

@MrVideo
The problem isn't BD-RB. It's the output file from DVDFab. It is definitely variable framerate -- in the example you gave me there are over 1,000 instances where timecodes indicate missing frames (or other anomalies) in the source. When BD-RB looks at the timecodes and sees that the source is VFR, it then looks to see what the minimum distance is between frames -- so it can determine the true original framerate. There is at least one frame in this source where the timecode difference is zero. Since there is no "infinite" framerate, BD-RB selects the next best framerate, which happened to be 59.97. Even when I tell it to ignore zero deltas between frames, it still finds a distance that would be consistent with 29.97 rather than 23.976. So... the bottom line is: don't create MKVs using DVDFab if you want to import into BD-RB. Last edited by jdobbs; 14th October 2018 at 15:46. |

You'd just import the DVD, and then select the playlists you want to output to ALTERNATE. BD-RB also has the advantage of importing multiple DVDs in a single import -- so, for example, you could import an entire season of a series (across 10 DVDs) into a single BD structure, and then, using the multiple batch function, create mkvs from all of them with just a few mouse clicks. I do that all the time. You can also set the minimum time variable, so extraneous material will be ignored. Last edited by jdobbs; 14th October 2018 at 15:39. |

On another project, a few of the files resulted in TSMuxer giving the following warnings: Code:
Warning! Source stream contain irregular pulldown marks. Mistiming between original fps and fps/1.25(without pulldown) exceed 100ms. Warning! Source stream contain irregular pulldown marks. Mistiming between original fps and fps/1.25(without pulldown) exceed 200ms. Warning! Source stream contain irregular pulldown marks. Mistiming between original fps and fps/1.25(without pulldown) exceed 400ms. Quote:

UPDATE: I took the VOB file and had TSMuxer create a TS file, keeping the pulldown flags. I then ran that through BDRB and guess what, the frame rate is 19.181 fps. No indication of variable frame rate via mediainfo.

I just used MKVMERGE to create an MKV out of the VOB. It indicates the framerate is variable. The bottom line is the source is corrupt. The 19.181fps represents the total number frames divided by the time -- which is a result of the variable framerate. MEDIAINFO can sometimes miss variable framerate, especially in atypical video files (like a VOB, which is rarely used without supporting external information). On a TS it doesn't even appear that MEDIAINFO even reports the "Frame Rate Mode". That's probably because TS has no indicator of a variable frame rate beyond the timestamps. BD-RB can be forced to scan (IMPORT_VFR_SCAN=1) regardless of what MEDIAINFO says. But even then it will only do it when there is a "Frame Rate Mode" entry in the MEDIAINFO results.

For mode I selected "Movie-Only Backup." Then I selected "Alternate Movie-Only Output." Within the list given I selected "MKV, Intact Video, Intact Audio" and saved it. I then did DVD import and selected a single title, the shortest one (which is the sample I provided). When I tell it to go, it built a BD structure. No indication of a MKV file being created. Color me confused. |

Is the DVD structure unaltered from an original disc? I ask because the VOB you gave me isn't consistent with the DVD standard (since it has a variable frame rate). If you are trying to use that one, something has happened to it in between the time it existed on a disc and it was created on the hard drive, and it is just going to fail again. Who knows... it may be some type of new protection scheme (though I doubt it). Since the timecodes are used to display output on the player, if someone manipulated a video stream in a VOB it just might not be rejected. But it would definitely fail to meet the standard. If it is a protection scheme, it is something new, because I've worked with literally thousands of DVDs during development and testing of DVD-RB and BD-RB and have never seen a variable framerate. What makes it even more rare is the weird variation in timecodes. Normally BD-RB would catch the underlying frame rate and correct it during the import's VFR->CFR conversion. Why would there ever be a period shorter than the distance between original frames of the video source when encoding VFR? That defeats the purpose of VFR. I may just change the algorithm so that it would use the "Original Frame Rate" when it is listed in the MEDIAINFO output rather than the value it determines from the timecode scan. That way the craziness shown in the VOB you sent me would just be ignored. But, with the crazy timecodes, I'm not sure DirectshowSource() would even work correctly during the VFR-->CFR conversion. It may be forced to drop frames where the interval is too short. Last edited by jdobbs; 14th October 2018 at 17:21. |

Thanks guys for the answers. I still am as confused as hell, but I'm THINKING that there must be some 'flag' or something that needs to be set going from the MKV which does play properly at 4:3 to the BDMV folder, when it then will display as stretched to fill the screen. What I should do is try to run it through BDRB and see what it does...

I'm going to look at the timecodes more closely to see where the anomalies are. Last edited by jdobbs; 14th October 2018 at 18:53. |

Mediainfo reports a time of 1:24
VideoReDo reports 2532 frames of 1:24:14 And then there is: Code:
DGMPGIndexFileNV15 DGIndexNV 2051 X32 c:\Program Files (x86)\dgavcdecnv\ e:\\VTS_02_1.track_224.m2v 45388328 [...] SIZ 720 x 480 FPS 30000 / 1001 CODED 2028 PLAYBACK 2535 100.00% FILM ORDER 1 No idea why the timecodes are messed up with this file and the other six files from the other project. I'm guessing that if I tear apart other DVDs that I have, I will end up with the same timecode mess. |

BD Rebuilder v0.60.03
I've updated the first post of this thread with a link to the latest version of BD-RB (v0.60.03). Changes for this release:
Code:
- Updated ALTERNATE encoding so that HDR information is kept when encoding UHD with HEVC settings. - Fixed an error in which particularly odd variable framerate sources might result in incorrect framerates during import. - Fixed an error in which conversion from VFR to CFR of 720x480/576 sources during import results in incorrect aspect ratio. - Added HEVC/No resize ALTERNATE presets to the default list for UHD output. - Corrected the x: function in filtering so it correctly finds and executes external filters when ALTERNATE titles are added to a batch filter via "Add multiple playlists to queue". - Fixed an error introduced in v0.60.02 that forced AVISYNTH mode rather than FFMPEG for frame serving when testing UHD backups. - Other minor corrections and cosmetic fixes. |

If VFR is forced off, the frame rate is still 19.181. |
