Reripped, cleaned etc. The result is the same. Powerdvd can play it correctly. I had no problem with my first 300 rips. This BD is the 301st. Anyway, DTS-Express secondary track cannot cause the problem?

Don't know
Try without the secondary audio, see if that works

I don't see how it could...

@jdobbs i sent a small pm regarding a new system i'm building and (3d) quicksync a couple days ago. I hope you'll find the time to send a reply as i couldn't find anything specific in the first post instructions about it.

Sorry, I don't check my PMs very often and usually ignore the notifications. I'll take a look.

Can anyone doing full disc 3d bd25 backups using an i7 6700k (and perhaps even a maximus viii formula MB) send me a pm with their preferred sw_decoder/encoder settings if they've experimented with the different ones (for Intel quicksync!). I'm building a new system to replace my old q9550 one. I know some had problems with visual artifacts on certain settings, and I've never had a core ix system.

Please PM's only. Don't want to drag this question into an off topic discussion.

@Ch3vr0n
I do full backups on BD25 with an i7. Encoding time for me, is the whole
duration of the film incl. extras. An can can send you my settings
YouŽll only have to set your prefered language.

Any chance you can start a thread/discussion?

I'm about to upgrade my older system (at least mother board, cpu, and memory... upgraded video to GTX970 already).. So I'd be curious of any issues to look out for, tips, etc.

I'd be happy to help you pick parts for a certain budget and fit for your specific use. I start with defining what my system use will be, the peripherals and budget and go from there.

@Mark_Venture RE: Any chance you can start a thread/discussion?

I second that recommendation. I wish Ch3vr0n & jdobbs would get together on that thread and give us some suggestions on how to get quicksync to work properly on 3D.

I already contacted jdobbs about that, his quicksync capabilities are limited. Only 1 older generation quicksync capable system. I will be doing extensive testing and monitoring the result for artifacts and report back. Though that will be a little while longer. Some parts are on back order and the chassis will be undergoing custom airbrush.

I started a thread about new equipment... asking for tips...

we can discuss in there... http://forum.doom9.org/showthread.php?t=173601

CRF prediction convergence?

@jdobbs
Full backup with 1-pass encoding using CRF prediction and "Quicker encode for Extras".
For some short clips (marked with an asteriks) I get a very long CRF prediction sequence, like:

Code:
.......
- [22:16:01] Extracting A/V streams [VID_01758]
 - [22:16:17] Reencoding video [VID_01758]
   - Source Video: MPEG-4 (AVC), 1920x1080
   - Rate/Length: 23.976fps, 1'678 frames
 - [22:16:17] Performing CRF Prediction...
   - Analyzing 14.65 7.83 4.41 2.71 1.85 1.43 1.21 1.11 1.05 1.03 1.01 1.01 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 [1.00]
 - [22:19:21] Encoding using constant rate factor.
   - Performing size-correcting second pass...
 - [22:22:19] Video Encode complete
.......
At the end, the size-correcting second pass produces a reasonably sized result. Just wondering if this is normal, or is there possibly a bug?

Edit:

My conclusion:
The problematic clips are language specific intro clips which consisted predominantly of black backgrounds with few thin white letters (e.g. name of an actor).
The CRF prediction tried to boost the file size to the targeted size, which -- based on the 2% sample frames -- drove the CRF down to 1.00xxx
The size-correction (great!) kicked in because the encode was slightly oversized (the full clip had some "normal" pictures at the end).
Some of these clips were even encoded at crf=1.00xxx without the need for the size-correction kicking in

=> After all, the final result was great and filled the BD25 to 96%, which is just perfect

Could the CRF prediction perhaps be stopped once it gets below say 5.0? Anyway, I think this disc is an exception (Bridge of Spies)

After I had changed the backup mode from full to movie-only (each of the other settings was kept the same) the encoding process of the main movie completed without any issue. Strange.

Jdobbs might have to look at your issue

In my opinion the outputsize is depending on min m2ts size and the custom output size. Im doning only full backups and in most cases
the output fits perfect on a single layer BD. That means 97 up to 98%.

@Sharc

I'll take a look at the prediction algorithm and do some testing. There should never be a time that the same value keeps repeating in the prediction. It should have stopped after the second time it hit the same value. I'm guessing it happened because the value was at the absolute minimum (1.00).

I was just thinking whether we could be fooled by the 2 digits rounding, and in fact it develops like 1.004,1.002,1.0016,1.00151 .... etc.

I'll look at that too.

B.t.w. I enabled the new prediction algo, i.e. NEW_CRF_PREDICTION=1
