I'll look. But I don't think so.

The real question here is why was the audio out of sync the first time you tried it? What kind of audio was it?

Hmm... I don't think I've ever seen a video file that used FLAC for its audio.

For the DVD conversion, the bitrate stayed within about 300kbps which isn't much in the grand scheme of things. But occasionally when creating quick play playlists from different sourced anime fan subs, file size can vary greatly - my last project has a 2gb HEVC 80 minute video and a 3 GB AVC 20 minute video - the second video was calculated at a much higher bitrate.

In the same vein, flac is a popular anime sub release format, since a lot of sources are Japanese with LPCM.

Trying to IVTC some Pokemon DVDs and am getting combing artifacts. Tried to add FieldDeinterlace as added AVS script, but anything added is placed before the plugins being loaded and the IVTC. Is there a reason for this?

Then tried to compare the results using just the default program deinterlace. Hidden options says that default is SmoothDeinterlace, and no field blending, but the workfiles script shows deinterlacing defaults to FieldDeinterlace with blend=true.

The real question here is why was the audio out of sync the first time you tried it? What kind of audio was it?

6 channel E-AC-3 JOC. BD_RB converted it to ac3.

I kept going back to my project of making episode blu-rays of 24 FPS files. I found out that the length of the imported files in the pseudo bluray is 4 or 5 seconds longer than the original files. That never happens with PAL or NTSC 23,976 of 29,97 episodes. With the use of ''IMPORT_FORCE_FRAMERATE=24'' the length of the episodes stays the same.

I wasn't aware of the ''IMPORT_FORCE_FRAMERATE=24'' option. Nice! Guess it's time to download the latest build. That will come in handy. Will eliminate the extra step I'm taking now when encoding menu background videos that are in 24fps.

The question is are the DVDs true 29.97 fps with 3:2 pulldown? If there is 3:2 pulldown, is the cadence there or was the source material edited 29.97 such that the pulldown cadence is drastically lost. If the 3:2 pulldown cadence is drastically lost, IVTC isn't going to be able to recover the 23.976 frame rate cleanly.

There are other reasons that could be causing the issue. You need to supply us with the technical info regarding the DVD.

TSMUXER ERR: 0xFFFFFFFE and a too large AV frame

I tried to make a blu-ray small enough for a 25gb disc by blanking half the content. But there was a pop-up with this content:

-----------------------------------------------------------------
Audio Detection Mismatch

The audio type for PID 1102 determined by reading the PAD/PMT
program information (DTS HDMA) does not match the detected audio
(AAC). In many cases, this is caused by emulation of audio headers
(false detection) and the PAT/PMT type is the correct type.

Hit Yes to use the PAT/PMT type.
Hit No to use the detected type.
Hit Cancel to disable this stream.

YES NO CANCEL
-----------------------------------------------------------------

The log mentions a TSMUXER ERR: 0xFFFFFFFE and a too large AV frame.

This happens when I hit Yes, but also when I hit No. So I think the real culprit is the AV frame.

Is there anything to be done? How to increase the AV buffer?

If all fails burn the mkv directly to the disc. As long as your BD player can play a file on a disc.

It's no mkv but a blu-ray

[doobre]

Could use makemkv” to create an mkv from the BD disc or folders

[Emulgator]

Maybe you hit a tsMuxeR demux limitation, or BD-R misinterprets a stream as being AAC.
(as blu-ray cannot have AAC audio)
You may want to demux the assets using DGDemux and work from there.

Thank you all for contributing. But after a re-rip all is well.
What a nuisance a faulty rip can be.

By the way.... Can the AV buffer in TSMUXER be increased?

[musiclover]

Just reporting a minor bug.

After BD Rebuilder reports an audio/PGS sizing issue and choosing to continue the log window stops reporting the progress of the remainder of the job. The log itself keeps filling up but it is not visible in the log window.

Not sure if it's the same for other sources, but when importing PAL MKVs with Pal to Film set, chapters aren't adjusted to fit the new timing. Not sure how else to do it, but MKVToolnix GUI allows you to set a stretch parameter in the options setting of chapter files - assuming it works in the CLI too - just in case you're not sure of a way to do it.

Also, it would be nice if when both Convert SD to 1080 and Convert 1920x1080 to 1440x1080 were selected, that the output was 1440x1080 - right now it only upconverts to 1920x1080 and ignores the other option.

What new timing? 25 fps film speed is legal for Blu-rays. If BDRB is trying to change to 23.976 (or 24) fps, IMHO, that would be wrong. By keeping it at 25 fps, there shouldn't be a timing issue. What did you end up with for the frame rate?

Also, it would be nice if when both Convert SD to 1080 and Convert 1920x1080 to 1440x1080 were selected, that the output was 1440x1080 - right now it only upconverts to 1920x1080 and ignores the other option.

I'm curious as to what you would convert from 1920 to 1440. Normally, taking a 1920 video to 1440 would end up squeezing it. If the video within the 1920 was 4:3, then you would have to crop the black vertical bars to get to 1440.

PAL to FILM is in BDRB hidden options.It's just to slow down 25fps to 23.976 so that it plays back smoothly on a 120hz screen. I've never tried to play 25fps on my Blu-ray player before- I'm assuming it would have to add frames to pad the video to play back at a standard 29.97 which would disrupt smooth camera panning.

I was given 500 single layer DVD+Rs so I've been playing around a lot - squeezing to 1440x1080 with sar 4:3 reduces number of encoded pixels by 1/4 - on a DVD-5 that gives better overall quality than encoding the same thing at full 1920x1080.

I mentioned SD to 1080, but I more often use the 720 to 1080 option for 29.97fps videos since encoding to 720p requires doubling the frames encoding at 59.94fps to be compliant.

All of this depends on your equipment, both the player and the TV. Thinking back, not all U.S. sold players support 25 fps material.Stupid really, but that is the U.S. product. IMHO, 120 Hz video playback is a gimmick. I prefer 23.976/24/25 fps material get displayed at that rate. What is interesting in that my setup, with a projector, results in 1080p/25 material being converted to 1080p/60. But, if I upconvert to 2160p/25, then the system will play it at 25 fps. AFAICT, 1080p/25 is not natural for my projector. It is the projector that doesn't like 1080p/25. The player is 4k and so is the projector. You'd have to look at the specs for your devices.

I was given 500 single layer DVD+Rs so I've been playing around a lot - squeezing to 1440x1080 with sar 4:3 reduces number of encoded pixels by 1/4 - on a DVD-5 that gives better overall quality than encoding the same thing at full 1920x1080.

Keep in mind you really don't gain much. Why? Because black compresses to a lot less bits. So, taking away the "few" bits doesn't really gain you anything. But yes, a lot of people do crop the black, which is why a lot of videos have letterbox bars removed as well. When it comes to 4K videos, I have to restore the black because the projector will vertically expand the video to fill 2160p. But 1080p material it leaves alone. Go figure.

I mentioned SD to 1080, but I more often use the 720 to 1080 option for 29.97fps videos since encoding to 720p requires doubling the frames encoding at 59.94fps to be compliant.

I'm not sure that applies to MKV files. Yes, Blu-ray authored 720p does have that framerate restriction. But, for simple MKV playback, it depends on what your hardware will allow. When it comes to Old Doctor Who episodes at 576/25, I have to redo them as 2160p/25 in order to play them at 25 fps.Keep in mind that my projector upscales everything (other than 3D) to 4K. So, by doing it myself, I can keep the frame rate.

I store all these videos on HDDs, not DVDs or BDs.

Fine print: YMMV

Hmm... I'll have to look at that. I know I adjusted audio and subtitles when that hidden option is set -- but it's been a while, and I can't remember how/if I adjusted chapter points.
