How do I find the inspect log?

2. Actually LAVF should be off by default. I'd recommend to do a test and compare the speed. The quality will be the same -- and on some systems LAVF is faster -- but contrary to what I'd originally thought, it can also be slower on some (that's why I changed it back to "off" as the default.

Thanks for the quick reply.

One last question; so if I turn on DECOMB filter then it wont affect the original movie which is 1080p. The reason why I am asking is because I have heard people say that if you de-interlace a 1080p video then the quality degrades significantly.

thanks

The deinterlacing options are only applied to interlaced sources.

Hi!

Here's one that will knock your socks off - and I'm pretty sure I know the reason for the anomalous results:

Background - The title of the Blu-ray is "Buried", with the ENTIRE movie shot inside a coffin, in which the lead (only) character is being buried alive. I'd guess that the BRIGHTEST lighting in any scene is no greater than 1 to 2 candlepower, including many interspersed moments of total darkness. (I'm guessing that the poor end result is due to the unusual lighting throughout the entire movie).

Since I'd been getting extremely good results of late, using settings of "Good" and "CRF" to generate BD9s of movies of over two hours duration and BD5s for those of two hours or less, I thought I'd try this one at BD5 (due to the lack of action, light, and colors) with the same settings.

The end result was a full disc of a whopping 1.34Gigs, with heavy duty blocking reminiscent of compressed videos we used to make using the ORIGINAL DivX hack of the MS codec.

(I am presently re-doing it, using the "Automatic" setting, which I'm fairly certain will yield good results)

This is the full log of "Good" "CRF" version:

I am quite certain your suspicion of this low lighting movie is the reason for your results. CRF would not be the best choice for such a backup.
I am also reasonably certain that, at our age, there is not much left that jdobbs would say would "knock your socks off"!
( Perhaps a late night visit from Sofia Vergara!! Might ? )

I see I am behind a couple of revisions, so I will download and try again. EDIT- With the newest version, I get the same result.

[Capsbackup]

@larrsz;
is there a reason you are not using the latest version, BD Rebuilder v0.37.05? It may not correct your problem but there were some changes in that version related to DVD output.

edit: I see you just caught this.

If the source is the original Blu-Ray rip, it works? Only if you try from the already completed BD9 backup does it fail?

I'm not sure what to say. I've now done 3 discs from BD-9 to DVD-5 and all three worked perfectly. I'll insert your settings into my INI file and see if anything changes.

@larrsz

I just loaded your settings in to my INI -- and and got the same "no problem" results. This is now four BD-9 discs that I've converted to DVD-5 (and now DVD-9) that went perfectly. I'm sorry, but I have to mark this one as not repeatable and move on to something else.

Understood. No worries. I'll use another method. THanks for trying. BDRB works for what I primarily use it for anyway.

[Capsbackup]

@jdobbs;
Just curious, but I notice from the BDInfo report of Centurion, which is a uniquely authored Blu-ray in itself, that the original has this for 00004.mpls:

Total Video
Title Codec Length Movie Size Disc Size Bitrate Bitrate Main Audio Track
----- ------ ------- -------------- -------------- ------- ------- ------------------
00004.MPLS AVC 1:37:41 0 29,458,776,053 0.00 0.00 DTS-HD Master 7.1 (48kHz/24-bit)

And the BD-RB backup has:

Total Video
Title Codec Length Movie Size Disc Size Bitrate Bitrate Main Audio Track
----- ------ ------- -------------- -------------- ------- ------- ------------------
00004.MPLS AVC 1:38:23 0 8,446,599,229 0.00 0.00 DD AC3 5.1 640Kbps

This full BD9 backup was created with BD-RBV03705, the audio is perfectly in sync from your latest find/fix.
I have checked a few others, but BDInfo reports identical movie lengths with the original and the backup.

- Bitrate: 5,223 Kbs
- [08:55:56] Reencoding: VID_00000
[08:56:06] - Failed video encode, aborted

I see I am behind a couple of revisions, so I will download and try again. EDIT- With the newest version, I get the same result.

Seems to me the only place this could be failing is with BD_Rebuilder\Tools\HCencoder.exe--maybe you could try using it manually and see what issues arise. I'm curious too what your BD_Rebuilder\LASTCMD.TXT looks like (following the failed encode)?

Are you running Vista or W7--I wonder if it might have something to do with Security Properties. I notice for example if I dl it separately and place HCenc_025.exe into BD's dir and compare these Security Props, they appear different. Dunno nuthin' 'bout these myself, just a puzzlement...

Just a thought, but a potential problem, maybe minor, but using a previous BD-RB backup as the source to make another backup could bring about audio distortion problems, since the original audio has been amplified by BD-RB ( Amplify(1.2)). One additional amplification may not create a problem, but any additional ones could!

Total Video

----- ------ ------- -------------- -------------- ------- ------- ------------------
00004.MPLS AVC 1:37:41 0 29,458,776,053 0.00 0.00 DTS-HD Master 7.1 (48kHz/24-bit)

And the BD-RB backup has:

Total Video
Title Codec Length Movie Size Disc Size Bitrate Bitrate Main Audio Track
----- ------ ------- -------------- -------------- ------- ------- ------------------
00004.MPLS AVC 1:38:23 0 8,446,599,229 0.00 0.00 DD AC3 5.1 640Kbps

This full BD9 backup was created with BD-RBV03705, the audio is perfectly in sync from your latest find/fix.
I have checked a few others, but BDInfo reports identical movie lengths with the original and the backup.

I don't think I understand your point. Yes, the audio was converted to AC3... as it always is on BD-9 backups. A DTS-HD audio track could take up the output size without even considering the video.

If it's the difference in length that is your concern - my guess would be that on the original the timing in the MPLS didn't include the silent "intro" screen. It is possible for an MPLS to reference start and stop points other than the beginning of the video.

Yes it is the video length I was referring to. The difference, 42 seconds, seemed unusual. There was a 18393 second time delay for the audio, but I just thought the overall times should match.

Regarding my post #11305 ("Buried"):

I performed a new conversion from the original Blu-ray disc, this time using "Automatic" setting and BD/DVD9 (rather than BD/DVD5).These settings yielded an excellent 7.6Gb full disc copy, as opposed to the pathetic, blocky 1.34Gb originally created with CRF...
