I may have to rethink this thing for 720x480 sources with pulldown. I just imported a movie from a DVD, output it to an MKV and then tried importing the MKV. I got the same alternating timecode intervals in that one too. It must be related to the pulldown somehow -- though I can't see how the spacing would look like that??? I may have to look for that pattern, and assume pulldown. But first I need to do a little more research. I'll let this one run and see if I can repeat the framerate issue.

From what we have seen, these two values have been working out: frame rate (23.976) and scan order (2:3 pulldown). At least for the test video when VOB converted to TS. The other is frame rate (variable), original frame rate (23.976) and scan order (2:3 pulldown). It seems that a variable frame is a false positive, even when the timecodes are all over the place. It sends one down the wrong rabbit hole.
As a side note, one of the DVDFab produced MKV files also resulted in a 3:2 aspect ratio when a VFR->CFR was done on it. Oh, and it all comes down to what you said... DVDs can't have variable frame rate videos. It must either be 29.97 or 23.976 w/ 2:3 pulldown, because analog TVs only support 29.97 interlace video. Of course, that is moot with today's digital monitors/TVs. IMHO, it was stupid that we kept the 29.97 frame rate when converting to digital broadcasting. I do not think there is an analog TV that wouldn't have been able to handle true 30 fps interlace video. But, that is moot too. That ship has sailed.

I figured out the 19.181 fps thing. When you mux a stream with 2:3 pulldown into the pseudo BD structure with TSMUXER the framerate has to be set to 29.97, not 23.976. If pulldown results in a 23.976 framerate, then it is assumed the underlying progressive rate must be 19.181. Duh...

I did not "choose" the bitrate, BD Rebuilder did that I chose Alternate Movie-Only output - MKV Container, HEVC, NO_RESIZE, Intact Audio. Constant Rate Factor Output (CRF) was set to 17. Last edited by Glarioo; 17th October 2018 at 19:52. |

BD Rebuilder v0.60.04
I have updated the first post of this thread with a link to the latest release of BD-RB (v0.60.04). Changes for this release:
Code:
- Corrected issues with file import of MPEG2 sources that contain 2:3 pulldown flags. - Added IMPORT_NO_PULLDOWN as a new hidden option. When set it will remove pulldown flags from MPEG-2 sources during import of files or DVDs. - Added two new hidden options. UHD_MAXRATE sets the maximum bitrate for UHD encodes and UHD_VBV_BUFFER sets the buffer size. See HIDDENOPTS.TXT for more information. - Other minor corrections and cosmetic fixes. |

I also changed the default for UHD to 50000/50000. There are two maximums listed for a 50GB UHD M2TS, the lower of the two is a maximum of 64Mbs for all streams in a single M2TS (audio/video/graphics). So 50Mbs leaves about 14Mbs for overhead/audio/graphics.

removes pulldown flags during import of MPEG2/DVD, keeping the original 23.976 frame rate Just a thought. A side note: I started working on another project and discovered some material was marked as variable frame rate 29.97. And there was material that was marked as variable frame rate 23.976 w/ 2:3 pulldown. All on the same DVD. Can't seem to make up their minds. |

Alternate MKV is incomplete
After three DVD files were imported, I then did the backup. Only the third M2TS file was wrapped into an MKV file, the first two M2TS files were ignored. Why is that?

When you import more than one at a time, do this: 1. Import multiple files. It creates a pseudo-structure with multiple menu entries. Let it finish importing. 2. From the mode menu, select the ALTERNATE method to be used (output format) 3. Go to the "Batch" tab. 3. Right-click on the queue area. 4. Select "Add multiple playlists to Queue" 5. From the list, choose the playlist(s) you want to output in the format you selected in step 2. 6. Push the "Batch Backup" button. That way you can create multiple MKVs. I've imported as many as a hundred in a batch (multiple seasons of as series, for example). |
