BD-Rebuilder, Feature Requests

[omegaman7]

Another thread suggested this was due to rebuilder attempting to reference audio that didn't exist, or was simply not present. This was the error. Since the error is generated by Bd rebuilder, perhaps it can forgo notifying the OS, and continue with the batch mode ;)

My experience is that when resizing downward Bilinear or Bicubic does a better job. If resizing upward, Lanczos or Spline does a better job.

Thanks for the tip. I tried a couple of manual encodes with HCgui and avs script with SetMTMode(2,0) at the top, using bilinear. The results were good with a bit higher fps throughput at slightly lower core utilization. I should have explored AviSynth in more depth earlier. There's a wealth of stuff there.

i have the feeling that resolution is not taken care of in the bitrate calculation

would be nice to fix/improve!

I am a long time user of dvdshrink for backing up my dvd collection. I have migrated to bd-rebuilder, and am loving it. I would like to see a feature to edit the content of the movie like you have in dvdshrink. With my movies I have edited out the credits and other extraneous parts of the main movie I don't want to see. Would this be possible with bd-rebuilder?

how easy/hard would it be to enable an option to reduce bitrate in a similar way to dvd rebuilder in that you could preview a title then reduce/increase the bitrate and then allocate the savings to another title?

Maybe... but, honestly, I'm trying to keep the complexity to a managable level. The biggest criticism I've gotten for DVD Rebuilder is that the number of features makes it confusing to some people. It does everything, but apparently there is a downside to "doing everything".

dvd rebuilder was a tweakers paradise, loved that app :)

maybe an option at start up - standard or tweakers version?

would be really handy on episodic disc so you could select the extras from the main episodes and reduce there bitrates

[omegaman7]

That probably depends on how much donations help him ;) Given my smooth experience, he can count on a good donation from me, in the not too distant future.

Well maybe those people should be sat down in front of Sonic Scenarist or "The GIMP". I am sure they would soon change their tune! :readfaq:

I was wondering if you could give us an option to have like a 3 pass for video encoding like we had when using cce.

[jdobbs]

I was wondering if you could give us an option to have like a 3 pass for video encoding like we had when using cce. I can do it easy enough... but it really doesn't accomplish anything. After the first pass you have everything you need to allocate perfectly for the second pass. Additional passes are more placebo and salesmanship than anything really useful.

[user822]

you could allow weightp as custom tweak since it is allowed in the bluray spec:

Most options after "tune" are required by the spec.

--weightp 0 is not, but there are known bugged Blu-ray player chipsets (Mediatek, notably) that will decode video with --weightp 1 or 2 incorrectly.

and it seems to be patched already on those problematic chips, read here: http://doom10.org/index.php?topic=941.0

Ok. sounds like a waste of time then. I'm cool with that. The encoders must have gotten much better over the years.

[Video Dude]

I believe jdobbs has already enabled this.

Take a look at the HIDDENOPTS.TXT readme file that comes with BD-RB, it lists WEIGHTP=n as an option. The default is 0, but you could change it.

Good to hear from Dark Shikari that --weightp 1 is compatible.

Good to hear from Dark Shikari that --weightp 1 is compatible. Unfortunately, though, if you set WEIGHTP in the INI it will only stop BD-RB from setting it to "0" -- and the X264 default is 2, not 1.

I'll change the hidden option in the next release so that setting WEIGHTP=1 will change also set it to "1".

[jdobbs]

Why not just default to 1? Is it positive that it won't cause any issues on any players? If so, I'll change it to the default.

[Dark Shikari]

Is it positive that it won't cause any issues on any players? If so, I'll change it to the default.99% sure.

[jdobbs]

I just changed it to the default... if there are any issues on any players I'm sure I'll hear about it. :)

If I got it right BD-RB seems to stick to --ref 3. I cannot change it with TWEAK_PASS_x, like --ref 4 for 1080 or --ref 6 for 720 for example which would be blu-ray compliant as far as I understand.
Is this something to consider for future release?

Is this something to consider for future release? BD-RB always uses "--ref 4" because that is the max for 1080 and 99.99% of all original blu-ray features are 1080p. It never uses "--ref 3". It does, however, use "--ref 2" if you have the HDDVD_COMPLIANT switch set.

"--ref 6" is the maximum for 720p -- but isn't required for compliancy. "--ref 4" is compliant.

[Sharc]

BD-RB always uses "--ref 4" ..... It never uses "--ref 3".....
Hmmm, are you really sure? Media Info reports always ref=3 for BD-RB encoded files. (I usually do 720p 2-pass encodes).

For comparison: when I do x264 enocdes manually, Media Info reports the ref according to my settings, i.e. 4 or 6, according to my --ref settings.
I am confused ....:confused:

"--ref 3" is never set manually by BD Rebuilder. But it is the default for X264, so it can be there when it isn't manually set by BD-RB. BD-RB only manually sets it when the default for a preset would make it non-compliant or for HDDVD_COMPLIANT. So, yes, it can be "3". That's compliant, but not optimal. I'll take a look at changing that so that it always defaults to "4". While I'm at it, I'll see about setting it to "6" for 720p also.

[Sharc]

Thanks :)

[jdobbs]

Thanks :) I've changed it for the next release. Since BD-RB's encodes are always either Level 4.0 or Level 4.1, a ref of 6 is legal for all output sizes except 1080. So I've set "--ref 6" for all but 1080, which uses "--ref 4". I've also added a hidden option that can force the value to 4 for all encodes (just in case I find a non-compliant player somewhere that doesn't like 6).

it's because b-pyramid, and it's completly fine.

I'll see about setting it to "6" for 720p also. Well it's completly compilant and usualy 720p encodes goes to DVD5, why not give possibility for more quality.

[Sharc]

So '--b-pyramid strict' could also be added per default?

[jdobbs]

So '--b-pyramid strict' could also be added per default? "--b-pyramid strict" is the default now. You can turn it off by setting B_PYRAMID=0 in the INI.

The "Use X264's internal LAVF" and "IVTC sources" options were added to the setup options a few versions ago. I have not set these options as yet. Can you give me some pro's and con's to setting these options as my defaults? Thanks.

[jdobbs]

Pros for LAVF
1. LAVF will in most cases be faster
2. LAVF will use the 64 bit version of X264 on a 64 bit O/S
Cons for LAVF
1. LAVF can't handle some sources and AVS will be used anyway
2. You can't use filters with LAVF -- so BD-RB will ignore it when they are selected
3. You can't do some resizing, any deinterlacing, and IVTC with LAVF -- so BD-RB will ignore it when they are selected
4. Since BD-RB is making decisions based on LAVF capabilities -- you're never positive which encoder/method is in use

Pros for IVTC
1. You'll get better quality on PULLDOWN sources -- because of lower framerate at encode
Cons for IVTC
1. Has no effect on PAL sources.
2. Might slow down the encode a little
3. Some PC CODECs don't handle pulldown output very well during playback.

jdobbs...Thanks for the quick informative response. If I understand you correctly, turning on LAVF seems to only have positive effects (I do have 64 bit OS) and won't be used if not appropriate. As for IVTC...if set, will it only be used if necessary?

Thanks again

I'd also like to request a feature: Could you please make the main window resizeable so that you can see more of the treeview? Now the window is quiet tiny ;)

[Sharc]

BD-RB/ALTERNATE Mode to DVD-5 (mpeg-2):
Presently the default matrix MPEG is used by HCenc.
I would suggest to use the built-in FOX3 matrix (*MATRIX fox3) as it is IMO better suited with respect to detail retention vs blocking for (normally) high quality Blu-ray sources.

[Hobojobo]

Is it (already) possible to handle audio streams of the same type differently?
For example, I have got two DTS audio streams, and I want to keep the default one as DTS and reencode the second DTS stream to AC3.
Or even an option to reencode all but the default audio stream?

:thanks:

HI FELLOWS
I have a question
in bd-rebuilder there's an option sd to 720p
what does it mean
sd from dvd ,vob format
or 480i/p from bluray disc
please help
thankyou

[jdobbs]

480i or 576i from a blu-ray disc. BD Rebuilder doesn't accept DVD as input.

[Capsbackup]

It would be welcome if there were an easier way to select an audio stream to keep/remove from multi-m2ts full movie backups. Since some of these type of movies can have 20+ m2ts files, and some can have several audio tracks.. descriptive track, commentary tracks, etc... keeping the main movie's audio track and a directors commentary track can be quite cumbersome selecting or deselecting each m2ts appropriately.
Keeping one per language means selecting the alternative desired for each m2ts, where keeping all per language may mean deselecting several for each m2ts.
Perhaps an association per playlist on these multi-m2ts backups, where selecting a track from the largest one BD-RB sees applies to all m2ts files in that playlist?

How about if I make it so that if you select or deselect from an M2TS that is part of a multi-part playlist, it will do the same for all the other parts?

[Capsbackup]

Yes, that would be perfect! If only I could have said it so short and precise. :)

[JoeH]

jdobbs,
I think as well it would be interesting to have a view of the "tracks" that are in a BD that is more like what EAC3TO / Stream extractor (http://forum.doom9.org/showthread.php?t=141829) offer, where you see the different playlists.

For me the biggest disadvantage of BD-Rebuilder has always been that the view of so many files is too complicated.

I suppose there must be some reason for the current setup - maybe there could be two modes, a "playlist" mode and a "file" mode, if the "file" mode is usefull for some.

:thanks:

jdobbs maybe, can you let us compress only 1 audio (like pcm to ac3) and we could keep the dts hd :D ? it could be possible right?

[jdobbs]

jdobbs maybe, can you let us compress only 1 audio (like pcm to ac3) and we could keep the dts hd :D ? it could be possible right? You can do that now. Select "Keep HD" from the SETUP page, and then add KEEP_HD_LPCM=0 to your INI file. It will keep all HD except LPCM, and LPCM will be converted to AC3.

Something that should be implemented in every software that requires a great deal of time to process, is the ability to instruct the program exactly what time to begin the job. Lets say you're running a program that's using a great deal of process strength. Your next job requires it too, and possibly the same hard drives. But it's bed time. You have a pretty good idea when the first program is gonna finish. So tell BD rebuilder to begin in 30 minutes. Or an exact time even. Though all that would really be needed is a specific length of time. Start in 10 minutes, start in 20 minutes, etc. :)

I suppose there must be some reason for the current setup - maybe there could be two modes, a "playlist" mode and a "file" mode, if the "file" mode is usefull for some. I've thought about that before, but displaying it by Playlist would be much more complicated. You could have M2TS files that are part of two or more different playlists... you could have a single point in time that could branch out to multiple M2TS files and reconverge. You can have 6 playlists that all represent the same film... and there is much more.

I prefer it the way it is. You see what is going to be processed in the order it is going to be processed -- and each M2TS/CLPI combination is represented only once.
