"Wow, those 'shrooms are p....r....e....t..t....y...." I think JD also muttered.

480i video squished
I have 5 pieces of 720x480 16:9 MPEG-2 video that I've added to a Blu-ray. But, when played on my Samsung BD player, it believes that the videos are 4:3.
Here is the mediainfo on one of the videos: Code:
ID : 1 Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings : CustomMatrix / BVOP Format settings, BVOP : Yes Format settings, Matrix : Custom Format settings, GOP : Variable Codec ID : V_MPEG2 Codec ID/Info : MPEG 1 or 2 Video Bit rate mode : Variable Bit rate : 4 204 kb/s Maximum bit rate : 9 800 kb/s Width : 720 pixels Height : 480 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Original frame rate : 23.976 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Scan order : 2:3 Pulldown Compression mode : Lossy Time code of first frame : 01:00:00:00 Time code source : Group of pictures header Default : Yes Forced : No What needs to be done for the BD player to get the correct playback flag? UPDATE: Found it... sort-of. I looked at the M2TS files with mediainfo and discovered that the AR was set to 3:2 and the frame rate to 59.94. That was a result of BDRB doing a VFR to CFR conversion. Why, I do not know. So, I disabled VFR->CFR and ended up with the correct AR, i.e., 16.9. But the frame rate was changed to 19.181. WTF? When that was played, the audio was correct, but the video was obviously slower. Why can't BDRB just place the video into a M2TS container without screwing with it? Is there a flag for that? There is nothing wrong with the video files, as they came off a DVD. I used DVDFab to rip the files into a MKV wrapper.

Are you sure the first conversion was 59.94fps? BD-RB would only do that if it had to convert it to 720p. I'm not sure why BD-RB assumed it was 4:3. I'm guessing, maybe, it lost it in the conversion?? You can force 16:9 by adding the following to your INI (see HIDDENOPTS.TXT): IMPORT_FORCE_ASPECT=16:9 Make sure you reenable framerate conversion before importing it -- and don't forget to comment IMPORT_FORCE_ASPECT out or delete it after you import that file, though, so you don't ruin the next import. If the framerate is variable, I doubt it came directly off a DVD, someone had to convert/reencode it first. If you still have issues, send me a short clip (dvd-rb@jdobbs.net) and I'll trace it during import. I made some changes to the import algorithm recently and there may have been some unforeseen impacts. Last edited by jdobbs; 13th October 2018 at 13:48. |

Sure. What kind of audio are you using, AAC or AC3?
But... I'm not sure if it will keep the HDR, I'll have to check the code. I'm not sure I considered ALTERNATE when I added that code. It also has to use FFMPEG as the frame server (to keep HDR). Last edited by jdobbs; 13th October 2018 at 17:01. |

Unfortunately, though, that will only work if you have an NVIDIA card that supports HEVC decoding (which I [and possibly others] don't). That doesn't mean that I can't add the capability -- but right now I have no way of testing it. I'm also not sure how it could work in a version of AVISYNTH that only supports 8 bit colors.

The DVD VOB file should be able to be dropped onto a Blu-ray, since MPEG-2 with 2:3 pulldown flags should be legal. Actually, any VOB file on a DVD should be able to be dropped onto a Blu-ray. |

A thought:
Code:
Video ID : 1 Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings : CustomMatrix / BVOP Format settings, BVOP : Yes Format settings, Matrix : Custom Format settings, GOP : Variable Codec ID : V_MPEG2 Codec ID/Info : MPEG 1 or 2 Video Bit rate mode : Variable Bit rate : 4 210 kb/s Maximum bit rate : 9 800 kb/s Width : 720 pixels Height : 480 pixels Display aspect ratio : 16:9 Original display aspect ratio : 16:9 Frame rate mode : Variable Original frame rate : 23.976 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Scan order : 2:3 Pulldown Compression mode : Lossy Time code of first frame : 01:00:00;00 Time code source : Group of pictures header Default : No Forced : No Experiment Update: I took one of the files and ran it thru TSMuxer and set it to remove the pulldown and then ran that thru BDRB. BDRB left it alone. I then played it on my Samsung BD player and it did not care that it was 480p23.976. As that violates the BD spec, BDRB will never do what I did. That said, The issues discovered still need to be resolved, as other users may have come across this problem.

I've never quite grasped the 1440x1080 thing... I THINK it has something to do with the shape of the pixels, I'm not sure. Is that natively a legal AR for Blu-ray, or if you import an MKV file with that AR into BDRB, will it simply automatically add borders to bring it to a full 1920x1080?
In other words, if I were to take that MKV file and run it through TSMuxer into a BDMV folder, I think I tried that before and my OPPO just stretches it horizontally to fill the screen instead of rendering it in the proper 4:3 AR. What exactly does BDRB do with a file with that AR? I've never been able to figure out how to place an MKV file with the 1440x1080 AR into a BDMV folder and have it play properly without re-encoding it and adding borders. And if that AR IS legal for Blu-ray, then why won't my OPPO display it properly if I just mux it through TSMuxer into a Blu-ray format? Do I have to change some kind of 'flags' or something, and is that what BDRB does? Can someone explain that to me. I've never really understood that... |

No need to add borders. |

All Blu-ray HD pixels are square. Taking 1920 and rescaling to 1440 (anamorphic) is not Blu-ray legal. Many cable companies have reduced 1920 to 1440, but that is OK for that technology. It is not OK for Blu-ray. |

The Wikipedia table just says "aspect ratio" without really defining what kind of aspect ratio. I'd argue it is wrong as it says
Code:
720×480 59.94i | 4:3 or 16:9 720×576 50i | 4:3 or 16:9 Last edited by sneaker_ger; 14th October 2018 at 10:09. |
