BD Rebuilder Beta - Bug Reports Only

[jdobbs]

I installed BD-RB on a new Windows 10 box. After starting the program I got the message "Your Windows 7 system has been succesfully configured to use LAV with BD Rebuilder". Is BD-RB not recognising my Windows 10 system correctly?No. Actually I was surprised at your post and went back and looked... for some reason I made the message box say "Windows 7"... Nothing to worry about, I'll change it.

I just put together a PC with a AMD Ryzen 3900X processor and currently trying to shrink UHD Aladdin to a 50GB disk. Why is my frame rate only 2-3 frames per second? I do have it set to do the highest quality. With this same settings on other Blu ray's I get frame rates around 40 frames per second?

[MrVideo]

Re-encoding UHD video takes a lot longer via software.

[BuddTX]

One other point. There's also the option to choose the fastest speed for X265 in BD-RB. My guess would be that it is similar to hardware encoding in quality -- and is a lot faster than, say, the default "High Quality" mode in BD-RB.

Interesting Observation JDobbs! I will take "your guess" any day!

So are you saying that the hardware encoding will not give as good quality as software encoding?

The whole idea of wanting to go to HW encoding is speed, but I also want good quality.

I don't want to spend hundreds of dollars on a new video card, and find out that the "best" it can do in HW encoding, is similar to the SW encoding "fastest speed for X265".

Even though I have a relatively new, GTX 1050 TI, it sounds like I would need to upgrade again, to take advantage of all the latest HW encoding options.

So am I understanding this correctly, that with HW encoding, there are limited options for video quality?

If that is the case, HW encoding does not interest me as much now. Of course, we all want speed, but quality is very important to me also.

I would not mind a "several hours-half day-similar time" encode, if I could use HW encoding and also use the "ENCODE_QUALITY=4" setting.

Thanks!

UHD is 4x the resolution compared to bluray ( 1080 ) and I guess HDR adds some time so Hella al lot more pixels to process

taken from another site hardware 265 encoding is coming on hopefully they can get turing cards better, and hopefully the next gpu cards will be equal

Hey mate, depending on what card you have, NVENC can perform as good as Slow on the right bitrate. Pascal and Maxwell cards don't beat x265 Faster. However Turing cards do. Turing cards in H.265 get much closer to Medium and Slow on x265. If you have a Turing card, and you use FFMPEG with some good options like -g 240 and spatial adaptive quantisation, you can basically get anything x265 can get. Some settings will still use CPU for rc-lookahead and the 2-pass preset "slow", but in terms of speed and quality Turing is the way to go now.

[jdobbs]

Given a high enough bitrate -- almost anything can give excellent quality. But at a given bitrate, you'll be hard pressed to find any solution that can beat X265. When backing up a blu-ray the average bitrate is fixed based upon the target size and the length of the source. While I haven't done any testing, I have doubts that a hardware solution could match it.

With that said... the bitrates are typically pretty high in BD backups, and its debatable whether most people would see a difference.

[BuddTX]

Thank you Mike-UK and JDobbs!

Mike-UK, I have a GTX 1050 TI, and that apparently does not have Turing, and am not anxious to upgrade my video card again! My 9 year old PC is still a workhorse, (6 core Xeon processor (12 threads with Hyperthreading), 24 gig RAM, 2 SSD HD, 2 physical HD), and was hoping to wait a few years before upgrading, because no matter what I buy, two years down the road, it is "not the latest and greatest!"

Mike, I would not know how to apply those command line parameters in the context of using BD Rebuilder, however your comment does make me ask a new question!

On the first post, JDobbs says:
CURRENT VERSION 0.61.05 (January 23rd, 2020)
2. While not required it is recommended you perform either one of the following (2A, preferred, or 2B):

2A. Download and install the LAV Directshow Filters (https://jammernhilftnichts.de/jdobbs/freeware/LAVFilters-0.65.exe). Use only the version linked here -- as other versions may result in out-of-sync audio. While not required for BD-RB to work, LAVFilters will improve functionality and are free. They are required for some functionality associated with HEVC import and processing.

2B. Download and install FFDSHOW (https://jammernhilftnichts.de/jdobbs/freeware/ffdshow_rev4504_20130312_clsid.exe) and the Haali Matroska Splitter (https://jammernhilftnichts.de/jdobbs/freeware/MatroskaSplitter.exe). While they are not required for BD-RB to work, they will improve functionality and are free. After the install, run "Video Decoder Configuration" for FFDSHOW from the "START/Programs" menu, and make sure MPEG2 decoding is enabled. Do the same using "Audio Decoder Configuration" to ensure "Uncompressed" is set to "All Supported".

2C. If you decide to install both 2A and 2B, make sure HAALI/FFDSHOW (2B) is installed first, followed by LAVFilters (2A). This will prevent issues with HEVC splitting.

I have always only done "2A", and BD rebuilder has always been reliable for me. However, in reading this, should I be installing 2B also? I use BD Rebuilder exclusively to make MKV files, and want to only use X265 encoder.

Reason for asking the question is this line (see bolded sentence):

2B. Download and install FFDSHOW (https://jammernhilftnichts.de/jdobbs/freeware/ffdshow_rev4504_20130312_clsid.exe) and the Haali Matroska Splitter (https://jammernhilftnichts.de/jdobbs/freeware/MatroskaSplitter.exe). While they are not required for BD-RB to work, they will improve functionality and are free.

I certainly would like to "improve functionality" to BD Rebuilder! Please advise.

Thanks!

[terrykuntz]

To increase the frame rate I tried 2 things, I added the option MULTIPROCESS=12 because I have the AMD Ryzen 3900X cpu which ended up changing nothing, frame rate still 3 frames per second. Then I changed the encoder settings to High Quality (default) and now the frame rate changes to 6 frames per second. Is there anything else I can change to increase the frame rate other than changing the encoder settings to a lower value?

[Mike-uk]

BuddTX, yes only the 20XX series Nvidia cards have turing chips, as for your other questions I have no idea but im sure there are people on here that can answer them

[MrVideo]

The GTX-1660 is also a turning card.

[terrykuntz]

I was trying to do the movie UHD movie Aladdin. It took 10 hours to build and it failed at the end: Failed to REBUILD, could you please tell me what went wrong???

yes 1660 is ok, but the 1650 does not support B-frames as its using the older chip

[Sharc]

The 1650 as well as the 1050Ti support B-frames for H.264 (AVC) but not for H.265 (HEVC).

Oops, my fingers got carried away.

[SeeMoreDigital]

Yep, I just uploaded some Samples with different CRF, let the video enthusiasts decide ... I can't see much of a difference ... even at a tenth of the original filesize.
The encoding for each file took less than 10 seconds, but the secondary stream from the orignal is lost in the samples
Original.mkv (https://jammernhilftnichts.de/download/Original.mkv) - 270MB
.....................
H265Main10High10bitLvl5.1QP24.mkv (https://jammernhilftnichts.de/download/H265Main10High10bitLvl5.1QP24.mkv) - 38MB

[Edit] You're right... you'd never guess by looking that the 38MB file was compressed that much more than the 270MB original.
Agreed.... I extracted the Dolby Vision stream from the 'original.mkv' file and added it to the 'H265Main10High10bitLvl5.1QP24.mkv' encode using TSmuxer GUI 'open source'. The OPPO plays the new mux in Dolby Vision without any issues and it looks very good indeed. Amazing...

Cheers

The 1650 Super does, is the cheapest one, quality still is crap vs x265

[SquallMX]

CFR mode produces badly undersized results in UHD mode, I think the issue is that the produced test pass has a lot of corrupted frames, and that screw the size prediction.

[jdobbs]

CFR mode produces badly undersized results in UHD mode, I think the issue is that the produced test pass has a lot of corrupted frames, and that screw the size prediction.Yeah. It definitely needs work. AVISYNTH apparently has a hard time locating a keyframe when pulling out encoding samples, and you end up with corrupted frames. I'd suggest using single-pass ABR instead until I can figure out a better way to select samples for prediction.

[sneaker_ger]

It's not really an AviSynth problem. Are you using LAV Filters to seek in HEVC-in-TS? It's a known limitation of LAV Filters to not seek to keyframes, then (because of the container not providing an index as opposed to mkv/mp4). I think with H.264 it at least mitigates the problem a bit by waiting for a keyframe which might be good enough for CRF/bitrate estimation. There's a reason people are more likely to recommend lwlibavvideosource() instead of DirectShowSource() outside of this sub-forum.

I am trying to reduce the Jumanji UHD movie from 54 GB to 46 GB to burn on a 50 GB disk. The re-encode takes over 11 hours then when trying to re-build structure it fails?? Why?? This sucks?

If I re-open of re-rebuilder and have it continue from where it left off, it rebuilds the BD file structure the progress bar on the bottom gets to 100 percent rebuild then the error occurs at very end?

[prologic]

Today .. Dvdfab failed to do a movie only, of
A Shaun the Sheep Movie Farmageddon...
It came up error on disk `message from oppo .

But BdRebuiler did it, no problem ..(with no re-encode) options.
but I also took 2 audio streams out .. Things are getting good.:thanks:

[jdobbs]

It comes from TSMUXER. Sometimes it just gets confused by the source. I'm not sure why yet, but if I can put my finger on the issue, maybe I'll be able to find a workaround.

How is BD-RB so wildly off-size? I have a blu-ray that's only 4.73GB, so I ask it to encode to BD-5 (4.37GB). Result: 3.73GB. This is with highest quality, 2-pass. The entire point of 2-pass is to get exact size. I've repeated this with FULL blu-rays, to BD25. The result is ALWAYS smaller than DVDFAB, thus, lesser quality. It's off by GIGABYTES. Custom size 23.3GB? BD-RB gives me 19-21GB.

BD-RB log (https://pastebin.com/vCqpQ5fx)From your log:

- Bitrate: 15,000 Kbs

You are hitting the maximum bitrate for an AVCHD disc. BD-RB can't make it any larger without risking exceeding the speed that a BD-5 can handle.

So... BD-RB isn't "wildly off-size" -- it is doing exactly what it supposed to do to prevent the disc from skipping and/or failing during playback.

shamelessly taken from another site


The Max official allowable bitrates for AVCHD are:

1. (BD media) ~24Mbps v+a+sub/pic
2. (DVD media) ~18Mbps v+a+sub/pic (this is supposed to also equal BD-9 spec)

and the new Max AVCHD/3D and AVCHD/60p rates are:
~28Mbps v+a+sub/pic (only BD media is supported)

As you can see, BD/AVCHD titles on DVD media are more limited by the spin/transfer capability of the DVD playback chain than by the spec's limits, so it often depends on the brand/quality of the playback equipment. Realistically speaking, you should set the target bitrate to fall in the 1/4 to 1/3 (possibly/occasionally 1/2) compared to BD rates.

[jdobbs]

And, although you mention it, I want to emphasize... the 18Mbs is the combined total of video, all audio tracks, subtitles, and muxing overhead (which is significant in an M2TS file). That's why BD-RB puts a 15Mbs limit on video.

[terrykuntz]

It does not matter if you select the target output to be 25 gb or 50 gb. Both selections fail. I do have an AMD processor. The final status is Current Progress: 100.00% and Overall Progress: 99.00%

One other point. There's also the option to choose the fastest speed for X265 in BD-RB. My guess would be that it is similar to hardware encoding in quality …..
Out of curiosity I made a quality comparison between cartman's QP24 HW encode and a BD-RB x265 'Very Good (Very Fast)' CPU encode at same bitrate (about 7740 kbps).

- cartman's HEVC QP24 GPU encode: VMAF = 95.7191, SSIM = 0.997884, PSNR = 49.1751
- BD-RB x265 'Very Good (Very Fast)' CPU encode: VMAF = 96.3585, SSIM = 0.997893, PSNR = 49.4838 (CPU encoding speed was about 9 fps with my i5-8400 CPU)

No big difference in the quality metrics, both encodes are softening and denoising the picture somewhat.
Visually they look much the same IMO, by far good enough for casual viewing (a very subjective statement of course :) ).
So the GPU HEVC encode has about the same quality as the CPU x265 'Very Good / Very Fast' encode in this test.

4K movie to a 4.46 gig DVD ?? youd be better off using a 1080p bluray version, can you even do UHD HDR to DVD ??( I guess so but HDR to SDR and a ton of wasted time to do it, for one the extracting of A/V takes ages compared to 1080p), it would need to convert HDR to SDR, so as said better to use a 1080p source if your wanting DVD, mayby explain more on what your trying to do ?

4K movie to a 4.36 gig DVD ?? youd be better off using a 1080p bluray version

Perhaps, but that doesn't clarify the problem nor should it impact EXTRACTING of the streams. The size issue should only come into play during rebuilding (if it would even start rebuilding).

Though on that issue, even if it's possible, it'll look like crap. Even with x264/x265

i done it with a couple other ones just to see how it looks even with DV it dont look bad at all or my eyes are but then i add atmos to it with tsMuxeR and every thing work good but not with black panther no matter if i do 25 gig still get that error

Atmos track on a DVD ?? that's out of spec, are you playing these dvds in a dvd player ??

Atmos track on a DVD ?? that's out of spec, are you playing these dvds in a dvd player ??Perhaps the tracks are being authored to suit the Blu-ray spec but are being burned onto DVD~R's.

copy them on my usb drive play them on my Sony UBP-X700 no problems then store them on my USB hard drive hooked to my 4k bluray player

Out of curiosity I made a quality comparison between cartman's QP24 HW encode and a BD-RB x265 'Very Good (Very Fast)' CPU encodes at same bitrate (about 7740 kbps).

- cartman's HEVC QP24 GPU encode: VMAF = 95.7191, SSIM = 0.997884, PSNR = 49.1751
- BD-RB x265 'Very Good (Very Fast)' CPU encode: VMAF = 96.3585, SSIM = 0.997893, PSNR = 49.4838 (CPU encoding speed was about 9 fps with my i5-8400 CPU)

No big difference in the quality metrics, both encodes are softening and denoising the picture somewhat.
Visually they look much the same IMO, by far good enough for casual viewing (a very subjective statement of course :) ).
So the GPU HEVC encode has about the same quality as the CPU x265 'Very Good / Very Fast' encode in this test.

Newer movies are easy to compress, try using an older one (35 mm film), I remember doing some tests with the original Ghostbusters, even at BD50 bitrate, the NVIDIA encoder was awful (http://www.framecompare.com/image-compare/screenshotcomparison/DZLPGNNX), grain retention was particularly bad.

Agree, but I wouldn't recommend superfast x265 setting for difficult sources and strong compression either.

The GTX-1660 is also a turning card.

'A Turn of a Friendly Card'...? :D

[Lathe]

Turning what/where? Towards the next model which is on the horizon? :p

quicker encode for extras ?? does this affect multi file discs, I have a disc with 4 files that make up the main movie 1 file is 130mb another 430, will quicker mode encode this low file sizes with lesster quality ?

Thanks
Mike

full bdrb log, or nobody can help you, and you need to provide a lot more info. For example, i own and use CloneBD myself and it does NOT support disc-to-disc backups of 3D titles. It only supports them to an alternate output such as mp4, mkv...

the "other" cloneBD apparently does full 3D 1:1 backups

[Ch3vr0n]

You mean the [emoji205] monkey? Or ClownBD? Afaik full disc to disc isn't yet supported by elby's CloneBD.
