Thank

ML That isn't hard to do, but what's the source? 1080p25 isn't a legal format on BD.

[morphus]

It's a Zone B (France) Blu Ray

[Ch3vr0n]

well that's my disc region (diff country though, Belgium is also region B), but the discs here are authored in 24p and not 25p. It's the player that "converts" it (if you can call it that) to 25p and then pushes it to the TV. Reason i'm saying this is because there's a setting on my panny DMP-BD85 that plays discs back in their native 24p mode. The only catch is that you have to use an HDMI cable to do so. I think morphus is confusing the actual disc framerate vs the one that gets output to the TV.

[jdobbs]

It's a Zone B (France) Blu Ray That format isn't blu-ray legal in any zone. The blu-ray standard is the same blu-ray standard everywhere.

[morphus]

Ok, but if I get the property of the m2ts file it says 25 fps not 24. And BD Rebuilder says 1080i 25 fps

Here is the detail of the first track according to BD Rebuilder
VID_00000 VC-1, 1080i, 25fps**, 33.668.49 MB

In PAL countries 1080i/MBAFF/25fps sources are quite usual.
These sources are normally not truly interlaced (the 2 fields are identical), but the standard requests these to be encoded as interlaced (e.g. using MBAFF), and BD-RB does this accordingly. So why do you want to convert to 24fps? One reason I would see is if you downsize to 720p. At present this is done by duplicating frames (converting 25fps to 50fps in order to comply with the standard) which takes considerably longer to encode. 720p/24fps (or 23.976fps) would in this case indeed be a nice alternative ;)

After that it's best just to assume the new framerate and adjust with audio. You could also drop one frame a second -- but sometimes that causes jerky action.

I want to convert it to 24fps because my North American Blu Ray player doesn't seem to like 1080i25, when I try to play a compressed BR with BDRebuilder, it will just not play.

BTW this is a Region 2 disc, for which I've remove the region code with AnyDVD to be able to play it in a North American (Region 1) player

[jdobbs]

Thanks Not currently. But I can look at adding it... I'm just not sure whether the demand justifies the effort.

[JoeH]

Thanks again for the latest DVD sub improvements for TSMuxer subs.

On Bluray to DVD conversion, the subtitles end up with a grey border. I find that makes them kind of hard to read and would prefer a black border. Is there a way to get that? If not, would you consider adding that option? Thanks a lot.

I tried changing the DVD_SUB_BACKGROUND=2, but that didn't seem to make a difference (I get the impression that is referring to something other than the border color as the default is transparent).

The problem with BD to DVD subtitle conversion is that the palette shrinks from 256 possible colors in BD to 4 (three colors and one "transparent") in DVD. So the best yoiu can do is hit the nearest average of the source colors. I choose a single color (white, green, or yellow) and do a grayscale equivalent of three colors. There are limits to what you can do with that -- so some conversions just have to be "as good as you can get". The only alternative might be a black/white two color arrangement, and having tried it, it generally looks worse.

[drmih]

This option may be present but I'm not sure how to implement it. Every so often in Batch mode an encode will fail, sometimes just down to a computer having a bad day. When the Batch moves on to the next title it automatically clears the WORKFILES. Is it possible when the program fails within a batch that it renames the WORKFILES directory and then continues?

The way to get around that would be to use a different workfile for each job. If space becomes an issue, tell BD-RB to remove the workfiles (REMOVE_WORKFILES=1) in your INI. The workfiles will only be removed if the job completes.

Feature request: I would like the final movie output to be named <movie title>.m2ts, not 00000.m2ts. This would allow me to keep my DVD-writeable BD trees intact AND also allow correct display of movie titles in WMC7.

Now, all the the trees have the movie 00000.m2ts which WMC can see, but all are seen as the same movie name.

Thanks

[MalibuDave42]

I would like to write the final tree to it final storage location. Second, would a RAM disk increase the speed of processing the files? If Temp was stored on a 8gb RAM disk.. increase speed?

Thanks????? The output is in Blu-ray format... anything other than a numeric name would be illegal. I'd suggest you rename them if you want them in some other format.

Regarding 1080p25 / 1080i25 - I have 3 UK bought blu rays ('Triangle', 'Super' and 'The Inbetweeners Movie') which are indicated as 1080i25, however all three are entirely progressive. I am assuming they were encoded with some kind of fake interlaced setting to make them 'compliant'.

I am assuming they were encoded with some kind of fake interlaced setting to make them 'compliant'.It would depend on the settings used. If "Deinterlace" was selected, yes, they would be encoded as progressive with "fake-interlaced" flags. If not, they would be encoded as interlaced.

Sorry, what I mean is, the actual original discs themselves are flagged as 1080i25 but are actually 1080p25. So the studios must have encoded them with some kind of fake interlaced setting.

[iSeries]

Exactly - but going back to the previous request someone made regarding 1080i(p)25 > 1080p24 conversion, in the case of a progressive stream marked as interlaced BD Rebuilder should encode as progressive even if de-interlacing is NOT selected, otherwise the output would come out as interlaced?

[jdobbs]

Well... not exactly. Most of the time the only difference between "progressive" and "interlaced" is the fact that a true interlaced source would have a temporal 1/50th of a second difference (in PAL) between fields at the time of recording, and therefore the fields should be analyzed and encoded with that in mind.

If the source is progressive but flagged interlaced, BD-RB would treat it as interlaced. The thing you'd lose is a bit of efficiency in the encoding since the fields are handled individually -- but the output would still actually stay "progressive" marked as interlaced -- since there is no temporal difference between the fields.

If you had "delinterlace" selected, a deinterlacing algorithm would be run against the frame (on a progressive source it would have little effect since there really isn't any interlacing), and the output would be processed as a full frame with "fake-interlace" flags applied.

Hi,
I haven't used BD-RB for a while:
Is it now possible to produce a mkv-video with more than one audio stream and subtitles using the alternate output option?

[jdobbs]

Hi,

Yes... but the only available subtitle format on most blu-rays is SUP, so make sure you player supports that type of subtitle.

[Racer]

I'm very impressed by the speed improvement of using DGDecNV. In the past my AMD 630 X4 never made more than 32fps with ffdshow, but with a GT520/GT430 I now get something between 42fps and 52fps. As I plan to switch to a new cpu in the future is there also a frameserver for the APU of AMD Trinity/Llano or Quick Sync of Intel's Sandy Bridge available. Then the discrete GT430/GT520 would be obsolete again.

[Hobojobo]

Just one more question:
I want to use BR-RB to create 720p-MKV-videos with
DTS-audio stream and one ac3-audio stream (and subs)

In the alternate.txt I can only specify aType=... for all audio streams

Can BR-RB process the first und the second audio stream in a different way automatically before muxing into the mkv container?

[omegaman7]

Here's a suggestion. Concerning the "Automatic black border removal" feature. Perhaps if people could specify the exact dimensions of the frame, it would minimize, if not cancel out the problems people are having. There are other programs that do this though. If they're so hell bent on it, they can use those alternate methods. Just a thought ;) I prefer leave the frames alone myself.

Just select the ones you want from the streams menu and use the setting for keeping the audio intact. If you want to reencode any audio, though -- you have to reencode all.

[Snarko]

The title says it all. Since there's already an option to decode with DGDecNV, why not also deinterlace and resize (when necessary/desired) with it also?

[jdobbs]

I did a little testing (nothing comprehensive) and it appeared that doing the deinterlacing and resizing that way was a little slower than using AVISYNTH. Actually I was a little surprised at that, but I moved on without looking any deeper.

I'll do some more extensive testing at some point.

[Snarko]

Good enough for me. Thanks!

[Guest]

[jdobbs]

I'm surprised at that too. What card do you have?I have a GT 520. But to be fair, as I said, I didn't do a lot of testing.

[Sharc]

Deinterlacing with DGdecNV yes, but resizing? Via the AVS template I assume, or did I miss something?
(Sorry if it's off topic).

[JoeH]

I have a GT 520. But to be fair, as I said, I didn't do a lot of testing.

The reviews of the GT 520 tended to say that it's deinterlacing performance was somewhat lacking. The higher end cards don't have that problem.

[gamete]

when is it possible to use

MULTIPROCESS=2

with x264 64bit ?


now work only with x264 32bit

[Video Dude]

jdobbs,

Would it be difficult to add a setting to change Blu-ray .sup subtitle color?

For example, I prefer light gray subtitles, but many discs have yellow subtitles, while other discs use other subtitle colors. I don't know if you can add an easy to use setting (even a hidden option) to change the color.

I don't know if you can add an easy to use setting (even a hidden option) to change the color. The problem is that it could be any of a huge number of possible colors... so I'm not sure how I would be able to determine "yellow" from "a little less yellow" etc. .SUP also includes graphics (like in popups) -- and when the setting is on it would ruin those as well.... but I can look at it.

thanks:helpful: Unfortunately you have to use X264's internal LAVF decoding when you select 64 bit, and that has an impact... but I can look at it.

[gamete]

ok thanks

[Sharc]

I suggest to add code to handle non-standard 576p/25 and 480p/29.976 sources and use "--fake-interlaced" in the command line to make them compliant.
(Same has already been done before for 1080p/25 and 1080p/29.97 sources).

[Revgen]

Not a feature request, just a comment. I couldn't find a comment thread so I thought this would be appropriate.

I was able to use BD Rebuilder to replace the horrible audio soundtrack on the Bird of Paradise (1932) Blu-Ray. You can read about it here. LINK (http://www.hometheaterforum.com/t/320513/bird-of-paradise-audio-issue)

I captured the Turner Classic Movies broadcast that aired recently, and it's basically from the same source as the Blu-Ray, but the audio, while not great, was certainly not as bad as the audio on the blu-ray. I was able to replace the original audio with the TCM audio in the WORKFILES and run the process again. It worked out fine, and plays great on my Samsung Blu-Ray player.

As far as I know, this is the only free solution that solves the problem.

Thanks to Jdobbs and the authors of the included software for your hard work. I appreciate it. :thanks:

[sreemv]

Not sure if this has been asked before but I am looking for a way to replace the .264 files under the "WORKFILES" with my own externally encoded streams before the "rebuild" step/stage - possible??

[jdobbs]

Not sure if this has been asked before but I am looking for a way to replace the .264 files under the "WORKFILES" with my own externally encoded streams before the "rebuild" step/stage - possible?? You can certainly do it -- just let the job complete, the swap them with the ones in the working folder, and resume. It will use the new streams the second time.

But why would anyone do that? You're not going to get a better encode than X264...

[sreemv]

But why would anyone do that? You're not going to get a better encode than X264...

You can? Going to give it a try.

The external encoding is still x264 with stolen x264 command line almost as-is from rebuilder but video post processing was done elsewhere [virtualdub] and not able to duplicate that with "avs"

Wonder if rebuilder can cope/adjust if the replaced .264 are different duration [longer] than original?

Obviously it would be ideal if bd-rebuilder can be paused after demuxing so it doesnt need to encode what is going to be replaced but I dont see a way - something similar to what DVDrebuilder has - 3 different buttons for the 3 stages.

Demux - encode - rebuild - would be really nice.

[sparkyar]

Just set a large custom output size and it will just demux rather than reencode...

Ive been doing that a lot lately because I usually replace audios and subs, But I want to know if its posible to replace a .vc1 with a .264 file. Ive tried changing the extension inside the mux file, but the mux file is rewrited every time you restart the process.

And I have another question, sorry if this has been asked a lot before, Its posible to chose what streams to process and what streams you need to remain untouched? for example when a full BD is 25gb, but the movies is 20gb and the extras 5gb, I only need to compress the extras to 50% and not the entire BD.

thank you
