Then I gave "Deepwater Horizon" another try with those settings which resulted in 21,9 GB and something came to my mind: Could the Dolby Atmos-tracks on that disc be the reason for BD Rebuilder's miscalculation? Both audio-tracks in the main movie are in Dolby Atmos 7.1.4 with a Dolby True HD 7.1-core. Maybe BD Rebuilder only gets something wrong here. The other discs I checked and which all were around 21,9 GB with the BD25-preset didn't have Atmos-tracks, so maybe that's the cause. Quote:
EDIT: Not exactly 22,9 GB but hey - 22,8 GB are also OK. Last edited by Thaddäus; 23rd April 2017 at 16:50. |

I had to remember that a few times also to switch it off.

1) 1080p with repeat frame to get 23.976 to 29.97 fps. 2) 720p 59.94 with 2:3 pulldown. |

I've still not gotten 2) to render to 23.976 or 29.97 correctly. Always jerky or 59.94 results. I haven't check into it for a while (private matters)...hence the lack of my replies.

The IVTC setting should do the job correctly. The AVISynth filter that Jdobb uses works with 720p 59.94 fps telecine video. Converting 59.94 to 29.97 with telecine material is not going to look pretty.

Xbox One S
Not sure if it's possible. But would like to know. What's the best settings to save or rebuild a Blu-Ray movie to a format that can be saved on a external drive connected to an Xbox One S and keep the original file size and audio (ex. Dolby Atmos). Where Xbox would recognize it like it was a Disc. Where you don't have to search the Blu-Ray folder looking for the right movie file to play. But hopefully like a disc.

Hello,
In Full-backup mode there is no chance to blank some of the very annoying m2ts files (mostly warnings) because they are not included in streamlist (even with MIN_M2TS_SIZE=0 set). If I change to menu&movie only mode they can be blanked in the streamlist but the menu will be not fully functional finally(e.g. after changing the language from English to an other in the menu and then playing the movie until the end, the viewer will not get back to the menu automatically (permanent black screen). If I do not change the language from English in the menu the menu seems to be fully functional). This is not happening in Full-backup mode but at the same time I cannot blank the unwanted, annoying m2ts files. Please help. My menus are not functioning this way.

So far, 59.94 to 23.976 is producing a very slight jerky output. I'm checking a few other files to see if the same.

Any chance you can post a snippet of the original, say 30 sec worth, and the same snippet after recoding. I can then look at them to see if I can see anything that sticks out. M2TS, TS, MKV or MP4 wrappers would be fine.

It is not 2:3 pulldown telecine source. You have to leave it as 59.94. Why? Because the source contains true 59.94 fps source and 29.97 fps source repeat framed to 59.94 fps. There is zero 23.976 source telecined. Even if there was in other portions of the complete video, what I've seen is enough to stop you from trying to do IVTC. Sorry, but that is why you are having issues. |

With a previous version of BD-RB, (49.xx)...??... I'd have to go back to check, anyway, then BD-RB was able to get 59.94 to 23.976 with IVTC, but since then it hasn't. So, I think there was a bug that JD caught. Laughing, I remember thinking, "Ahhh, man!! Back to HandBreak" since it wouldn't do it anymore. Anyway, now I know there are 2 possible differences in 59.94, not just a "bug" causing a challenge. This is what's really complex to me and I'm attempting to understand it. Hence the joking friendly comment to Lathe a while back. This is why I wondered if there's "switch" that could be added to BD-RB (not really knowing how else to ask the question) to "force?" a 23.976 or 29.97 framerate which HandBreak "seems" to do so a rerender without transcoding becomes possible. Hmm.. Really appreciate the continuity help with this. I also understand why JD prefers sources like this to be kept in original form.

That's also my experience, from some discs you can remove all boring warnings, from other ones (e.g. Teenage Mutant Ninja Turtles 2) you can't. I use MultiAVCHD in that cases, but since it seems to be not longer developed, it fails on new movies more and more. It would be really great if BR would allow to blank all warnings, regardles where they are hidden.

Keep in mind that changing frame rates also requires a re-encoding. There is no way around that. You can't just "drop" frames in a 59.94 fps video to get to 29.97 fps. That isn't the way digital video works. |

I can see the difference between using CloneDVD 2 from Elaborate Bytes if allowing it to clone a DVD using DVD-5 transcoding for rerendering vs DVD-RB's BEST 2-pass rerendering using HC as the encoder after disabling CloneDVD 2's transcoding using DVD DL. As an example. That means to me, using CloneDVD 2 to clone to a DVD-5 uses it's transcoder to rerender. Using it to process in conjunction with AnyDVD to rip a DVD but using DVD DL disables the transcoder and makes it all lossless to then use DVD-RB to rerender in 2-pass in BEST quality produces a much better looking DVD, I can see very well. I can also see the transcoded CloneDVD 2 version looking much worse, but to "normal eyes" of friends, it looks ok or GOOD.
When using BD-RB and disabling CRF/ABR I can see a difference in quality in whatever video I'm having it rerender. To me, and I'm realizing now that I might have been misunderstanding something in the reencoding process for some years now, that means transcodiing is disabled and quality encoding is happening. I understand it doesn't "drop" the frames, I'm lacking in technical words to explain and attempting to get it across. :-) I understand when I used 29.97 and changed to Constant Framerate that means clicking "Start" means it starts a rerendering process otherwise it would all be lossless, or untouched. In my mind, and I'm realizing I might have accepted something incorrectly for some years, that if the video is rerendered to it's actual source framerate that it's in better quality, AND...you can change the size of the file to fit projects. I'm still considering I might have taken on some misunderstandings. Ahhh, evolution.

There is no such thing as lossless recoding. Any time a video is recoded, there are digital losses. Depending on the bitrate involved, the loss can be so subtle that the viewer cannot see it. But, each and every re-encoding results in added digital artifacts. Initially, the broadcast industry was kinda worried about the re-encoding that goes on from the production stage up thru the broadcast stage. But, that point is kinds moot now that the video that is broadcast (OTA/cable/DBS) is so bit starved that it can look horrible.
You also cannot have something re-encoded and have it "look better" than the original. It is impossible to create something from nothing. It it like those TV shows where a still image, or surveillance video, is "enhanced" to get a sharp clear image. A crappy pixel image is going to stay a crappy pixel image. When you re-encode from 59.94 fps to 29.97 fps, one of two things has to happen: 1) every other frame is dropped, or 2) two consecutive frames are blended together to create a single frame. You didn't say why you want to go to 29.07 fps, instead of keeping the original 59.94 fps video. The general rule of thumb is that when you re-encode, in order to reduce the added artifacts, is to have at least a 2:1 bitrate difference. That means if the resulting bitrate is 10 Mbps, the source bitrate needs to be 20 Mbps, or more. Keep in mind that 20 Mbps MPEG-2 video is approximately equal to H.264 video at 40 Mbps. So, recoding 10 Mbps MPEG-2 video to 10 Mbps MPEG-2 video does nothing but add digital artifacts. It will not result in a better looking video. Recoding from 10 Mbps MPEG-2 video to 10 Mbps H.264 video will result in fewer digital artifacts due to the 2:1 ratio and the better H.264 encoder. But, in all cases, the resultant recoded video will not look better than the original. |

Now, you were saying that you cannot change the frame rate without re-encoding. How then does TSMuxer allow you to change the frame rate for the video track when it is simply remuxing the file...? Many times I get 'a hold of' an MKV file where when I drop it into TSMuxer it shows an improper frame rate of 90,000 fps (or something like that) I just choose the correct fps from the drop down menu. I can choose 24,000/0001, 24, 25, 30, 30,000/0001 if I remember correctly, and when I remux it, the actual frame rate DOES change to whatever I've chosen. So, if it is the wrong one, the A/V sync will be off. How can it do this without re-encoding? |
