Blocks / Pixellation after BD Re-Builder or DvdFab

[PhilippeB]

I am experiencing random Blocks / pixellization after Making a movie-only.
This may happens only once in a whole movie, or many times on others.
Also, sometimes the image will skip half frame like if there was some bad data or missing data in the encoded stream.

Here are my steps so far:
- Rip VC-1 or h264 movie in .iso using AnyDvdHD latest trial
- Open in BD ReBuilder 0.30 or DVD Fab 6 beta
- Proceed with 'Movie only' conversion keeping both (best) English and French tracks (no audio reconversion)
- Burn to BD-R (25G) with Img Burn @ 4x.
- Play on Sony BDP S550.

I saw the effects are present on the files before burning them so it is not a burning issue.
Since it happens (more with DVD Fab 6, Less with BD-Rebuilder) i though this could be a codec issue = S

in FFDSHOW, the h264 codec shows as 'libavcodec'. I Run Win7 + i7 950.

Any hint would be greatly appreciated. I like coasters but @ 4$ each, they become expansive = )

There are (4) quality levels for compression in BD Rebuilder, which 1 are you using? In my experience (30+ movies) the "highest quality (slowest) is the only one that looks perfect

I use the 'next to the slower' option.
I can try the slowest option available but i doubt the problem will fix from there.
This seems to be CODEC related matter. Also the fact that i am running Win7 doesn't help on the codec side.

Will try tonight and come back with results.

Thanxs

I have been running Windows 7 for months, and I am getting good results w/ BD Rebuilder on all my BD-25's and 4 out of 5 BD-9's @ ALL HIGHEST QUALITY SETTINGS

You got a choice: quality or speed

ps you don't have to change anything in ffdshow, you can leave it @ default settings

Hi again.

I have followed the previous suggestions. Unfortunatly, as i expectd, this was not the problem. Several coasters later, i am still stucked with weird image noises appearing randomly in the movies i pass through BD-Rebuilder. Even with max quality and BD-25.

I will try to attach two screen captures to let peoples see what i mean, maybe it was not clear at first. Theses frames are taken from the BD 'Ghosts of Girlfriend Past'. I give thoses frames as examples, theses errors of encoding appears on every movies i do. BTW BD-Rebuilder use exclusively x264 as codec, so this narrows the problem a bit (is x264 allergic to win 7 ?)

Thanxs for any feedback.

Another bas frame example (less obvious than the previous one)

I don't know what to tell you, there is not inherently anything wrong w/ Win 7 or its codecs, BD Rebulder or any combination of the 2 or we would all have problems

Gotta' be something else wrong in your system, or w/ your playback device

Good Luck

[guns1inger]

What are you testing playback with ?

[PhilippeB]

I did one more check this morning, that after ripping the files are still intact and they are. No artifacts at all on the .iso i ripped. So this discards both the blue-ray reader / burner, the RAM, the hard drives etc.

IF ANYONE ELSE EXPERIENCED THIS PROBLEM PLEASE COME ADD TO THIS THREAD !

Thanxs everyone.

[ulapines]

I have the same problem encoding with RipBot which also uses x264.
OS is WinXP.

Okay. I've seen that a few times. In each instance, I'd install the newest version of ffdshow, and get the very latest BDRB. The problem would go away.

Are you trying BDRB for the first time, or have you successfully used it before?

For the last several months, it seems like there's a new version of BDRB and x.264 each week. And I don't think that's much of an exaggeration. ffdshow has also seen many versions in that time. At least twice, the problem has returned (for me), and reverting to the earlier working versions of BDRB and x.264 has fixed it. Then another (even newer) version of BDRB has worked. I've just put it down to beta software, not knowing any better. :P

BTW, set ffmpeg-mt (multithread) to decode h.264, rather than libavcodec.

Update ffdshow, BDRB, and x.264. Worth a try, anyway. Good luck.

@PhilippeB

that is some nasty corruption, but it doesn't look to me like it's an encoding problem, it looks like a decoding problem. what software player are you using to get those screen shots? have you tried different players? perhaps changing some options? despite the corrupt images you're seeing on your computer have you tried to burn a disk and try out on your
sony blu-ray player anyway?

lastly, why are you going through this process to begin with? you obviously have the original blu-ray to begin with, why re-encode it? let me guess, you're renting the blu-ray movie so that you can copy it but you don't have a BD-50 burner.

personally i consider it a waste of time for 2 reasons:

1) if the source codec is vc-1 the resulting transcode will almost always look like crap compared to the original, vc-1 is notoriously hard to transcode from, i have yet to see a single transcode done to h264 or mpeg-2 where the source was vc-1 that didn't look shitty.

2) is the source is using h264, you are basically re-quantizing the file to half the size while keeping the same resolution, it's like when people used to take a dvd-9 and "rebuild" it to dvd-5, the results always looked atrocious, despite what the people that were doing it claimed. looking at the screen shots you posted, even if we don't take into account the parts that show corruption, the encode stills looks like shit. all you have to do is think about it for a second, if the production houses could get away with using half the bit rate (which is what you are going to squeeze BD-50 onto BD-25) wouldn;t they have done it in the first place and save money by using less expensive media and shorter encode times?

perhaps you should consider setting your target as avchd, basically take your 1080p movie and transcode it to 720p, h264/ac3 that you can burn to dvd-9 and that will play back on you blu-ray player and ps3's.

just something to think about.

[dannyboy48888]

I have seen this behavior before. one scenario is a bad rip (bd+ protection not removed all the way) another time i have seen this is using ffdshow to decode the movie in MEGUI vs dgavcdec. if the source is VC-1 use the m$ decoder (yes I know this sux....). This should fix your problem

[dannyboy48888]

oh yeah, forgot if you got the ffdshow decoder set to "drop frames to keep sync" and "disable delblocking to keep speed..." this will also cause the above. those options are only to be enable for playback not frame-serving so make sure you disable them when you framserve

[PhilippeB]

Answering deadrats:

BD i rent / borrowed to re-encode on BD-25. Not because i don't have 50G burner (they all do both), simply because BD50 are still 15$ while you can get 3$ BD-R. Only stating what's obvious... don't i ?
I found h264 (MPEG4) much more permissing on compression than MPEG2 was as i understood but again, ain't i stating the obvious again ? (i'm new to this so don't know so much)

VC-1 did cause a challenge at first because FFDSHOW had use microsoft codecs by default (i understood VC1 comes from microsoft). Two ways around it: a) choose another codec, b) use a patch that fixes the registry allowing BD-Rebuilder to use microsoft codecs in windows 7 (i believe this is the one i kept).
There is no vc1-h264 conversion required as everything goes vc1->vc1 as i understood.

Sincerely I can't tell the difference between a BD-50 (full of useless bonus features, menus, extras) and a stripped-down version BD-25 'Movie only'. I watch them on a High-end home theater system (67" Samsung + 7.1 Yamaha).

Finally, i think the main purpose of BD-Rebuilder is to 'Shrink' down BDs to whatever peoples want to put them on (some goes down as little as BD-5). Not to complain but your comments may seem to me a little bit out of league here.

Answering dannyboy48888:

Thank you verry much for your time. You are bringing tangible clues here. So:

a) my rip is good - If i play my .ISO file after ripping (with cyberlink power DVD that came with my blue-ray burners) it plays flawlessly everywhere i see the 'garbage images appear).

b) After encoding / re-packaging with BD-Rebuilder, every resulting BD structure plays with random image garbage that may appear maybe 5-10 times during a movie. They usually length less than a second.

c) Don't think it is VC1 related, it does that with any source i got (both VC1 and h264). This one from which i took the captures from (in power dvd) was a resulting h264 rebuilt @ maximum quality settings.

I will look into ffdshow tonight for the deblocking options. I though BD-Rebuilder was solely relying on x264 thus, not going through anything set in FFDSHOW but if this is the case, then i have some checkings to do

Thanxs !

Answering fritzi93:

Thank you also for bringing this in.

Like i said, i'm a new commer. I've installed my pack of applications maybe a month a go not more. I may already be out of date so i'll try to go through what you said (though i had no other options than using libavcodec if i remember well) but an upgrade can't hurt.

So far, i don't thing i could come up one time with a movie without theses corruptions. They all inherited of it. This is worse than H1N1 !

Thanxs

1 small caveat on your 2nd point, In my experience 85% of BD50 movies when demuxed to main movie fit on a BD-25 w/ no compression @ all, the rest usually take very little compression, i have never seen the need to "requantisize to half, 10 or 20% compression @ the most lol

Juste to let you know guys i am still out of solutions.

I re-did the same movie tonight after updating BD-Rebuilder and FFDSHOW. Also checked for thoses options to be left checked out on the VC1 codec (the movie WAS VC1 - sorry !) The codec is set @ WMV9.

Images are still corrupted - not at the same place, but i guess i could encode 100 times the same movies and images corruptions would arise at diffrent places - this seems to be totally random !

See another screen capture attached

[manono]

How's your PC memory? OK? Maybe running Memtest86+ to test it might rule it out as the source of the corruption. I had a stick go bad once and it gave out with random corruption like what you're showing, maybe 8-10 times in a reencoded DVD. I have no idea if this is the problem or not and have never even seen a Blu-Ray movie, much less reencoded one, but it seems to me a possible hardware problem is worth investigating.

BD i rent / borrowed to re-encode on BD-25.

That would be in violation of our rules. Please read our rules before posting.
