Forcing "No-Reencode" of Video in BDR

Greetings, all!

Please, I am wondering if someone could detail a foolproof way to -FORCE- BD Rebuilder to -NOT- re-encode a supposedly Blu-Ray compliant video stream (which is imported as a video file [File-->Import-->Video File])?

My AV video files are compliant enough to create 1.78:1 or 4:3 AR NON-reencoded AVCHDs using multiAVCHD (or 1.85:1, I just accept the 3.8% horizontal "squeeze" of AVCHD to 1.78:1 video). Of course, AVCHD will not help with widescreen or 1.66:1 (or, technically, with 1.85:1) AR videos.

In testing BDR, I've tried:

1) In the BDR install directory, in the file "BDREBUILDER.INI", I've inserted the parm "FORCE_NOENCODE=1" as line 5.

2) At the same time, I've also tried BOTH keeping other video encoding parms below that one, AND deleting them from "BDREBUILDER.INI":
[line 3] ENCODER=0
ENCODE_QUALITY=2
ONEPASS_ENCODING=2
AUTO_QUALITY=0
PRIORITY_CLASS=0

3) I've also tried taking the Input BD size from the log, multiplying it by 1024, and plugging the result into the parm "Custom Target Size" at the bottom of the Setup dialogue panel (before starting up the backup again, from scratch):
"- Input BD size: 4.10 GB"
4.10 x 1024 = 4198.4
"Custom Target Size:" 4198 "Megabytes"

THE BOTTOM LINE:
The parm "FORCE_NOENCODE=1" is accepted by BDR, and it emits the message "- FORCE_NOENCODE: May violate standards". HOWEVER, RBR announces it is "Reencoding video"--and it appears to me that it is really reencoding, since it indicates an ETA of about 89 min. for a 93 min. video (for x264 1-pass VBR encoding, at "Default"["Slow"?] quality).

Help! Am I doing one or more stupid things, or is non-reencoding imported MKVs/MP4s just not possible with current versions of BDR? --Or is this significant processing time normal, and I am I just not waiting long enough through the process?

Many thanks in advance!

"supposedly compliant", but BD-RD finds a reason to reencode, so... mediainfo of your source please.
BD-RB log please.

For what it's worth. I author MP4's to Blu-ray (using multiAVCHD) all the time, the audio and video of which appear to be Blu-ray compliant. The resulting video plays fine if I don't re-encode, both with my software and hardware based Blu-ray players. Here's the catch though, at least in my case. When attempting to rewind, fast forward, or advance through the chapter stops it's extremely laggy. It's laggy to the point it might as well not even work. If I re-encode the same video there are no issues with the resulting Blu-ray. The ability to rewind, fast forward and advance through the chapter stops is always silky smooth. As for BD Rebuilder, I only use BD Rebuilder to create "Quick-Play" menus, so perhaps others will chime in.

I fed it a folder created by BR Rebuilder as the source and the re-encode was indeed skipped
It seemed OK when I used the complete bdmv folder as the source.

But when I copied the m2ts file out and used file/import /video files,
the file was successfully imported, the pseudo structure was build, and it proceed to re-encode.

Why?

It seems to me that the source MP4s you're talking about were not encoded specifying keyint or it was set too long, which is what causes horrible lag when searching or skipping, but especially searching. And when you re-encode the video, you or the encoding software are setting keyint to a shorter length, so it's easier for you to search or skip chapters.

From my usual, favorite x264 parms, these two have seemed to work fine with multiAVCHD-created discs on an older Sony BR player:
--keyint 250 --min-keyint 1

I don't know too much about x264 encoding, but I always select the encoding parm "zero latency". Could this parm be a factor in this case of search/skipping lag?

That, honestly, I don't know. I just know from experience that not setting a keyint to a lower number like one or two seconds as opposed to the default, which I think it's 250, which would be ten PAL seconds, produces videos that are a pain to search whether it's played on computer or disc player.

Look here for some sample x264 bluray compliant command lines

There is no 960 width in Blu-ray, so non-compliant, BD-RB has to reencode.

There is no 29.970 fps with 720p in Blu-ray, so non-compliant, BD-RB has to reencode.

1280x720 @ 59,94p 16:9 DAR would be a compliant 720p source.
Pad with black bars before encoding, frameinterpolate to 59,94fps.

If the content needs to stay 29,97fps
then
pad & resize to 1440x1080x29,97i @16:9 DAR (progressive content, encoded as fake interlaced is possible)
Or
pad & resize to 1920x1080x29,97i @16:9 DAR (progressive content, encoded as fake interlaced is possible)

After weeks of researching this, I learned that there's one setting that is named differently, but works as FORCE_NOENCODE=1 does, of course as long as the total of your files is less than your target disc size.

The setting is:



And I see that this setting is off in your ini file. In the ini file, you can find it as "BDMV_CERT_ONLY=0". If it's 1 instead of 0, then your disc will build without re-encoding, but that doesn't mean that it will play fine in every player.

Emulgator is right in this last post, you have sources that are way off spec, so the disc might build without re-encoding, but when you want to play that particular file, or the whole things if it's just one, it may stop playback or turn off the player.
