BD rebuilder Profile Hight@4.1?

[BlayzeX]

how do you get bdrebuilder to set teh profile...seems it is defaulting to 4.0?

[Sharc]

It sets the profile automatically to 4.0 or 4.1 according to the target and other settings, in order to ensure device playback compatibility.
There is no reason to change this.

thanks

What other settings determine the profile? I am having the same issue with .mkv output.

What issue are you referring to?
The automatic profile setting?

I"m using Alternate Movie-Only Output and it keeps defaulting to
Level 4.0. Trying to get Level 4.1

"C:\Users\xxx\Documents\BD_Rebuilder\tools\x264.exe" "E:\MISC\BD REBUILDER\WORKFILES\VID_00000.AVS" --preset medium --bluray-compat --b-pyramid none --weightp 1 --qpmin=0 --bitrate 14000 --level 4.0 --qpfile "E:\MISC\BD REBUILDER\WORKFILES\VID_00000.CHP" --aud --nal-hrd vbr --pic-struct --vbv-bufsize 30000 --keyint 24 --min-keyint 1 --ipratio 1.1 --pbratio 1.1 --vbv-maxrate 30000 --threads auto --thread-input --stats "E:\MISC\BD REBUILDER\WORKFILES\VID_00000.AVS.264.stats" --pass 1 --output NUL

Looking at the cmd line, I have to ask...
Why do you need Level 4.1

[gonca]

From Hiddenopts.txt

TWEAK_PASS_ONE=s s = X264 pass 1 command line tweak(s)(warning -- for experts only, bugs not supported)
TWEAK_PASS_TWO=s s = X264 pass 2 command line tweak(s)(warning -- for experts only, bugs not supported)

Did you try these settings?

[rax_y]

Yes I have. Along with "TWEAK_ALTERNATE=s". I'm new to BR Rebuilder so I am probably not entering the correct code. That's specifically why I joined this forum. Appreciate the feedback. I"m going to start a new thread if you do not have any other suggestions?


Thanks,

[gonca]

TWEAK_PASS_ONE= --level 4.1
TWEAK_PASS_TWO= --level 4.1

[rax_y]

I will give it a shot. Level 4.1 is the original blu ray level. Trying to retain that.



Thanks,

Well if you set the level to --level 4.0 of course you are going to get level 4.0 out of it. And 4.1 level is needed when the bitrate exceeds 24000 kbits which is very unlikely when you set it at 14000. I see no reason to use it in this case since the target bitrate is far below spec and using 4.1 means you will need to use 4 slices which reduces compression efficiency.

Gser, I'm not setting the profile level. That is my LASTCMD.TXT. This is why I made the original post. Trying to figure out why it's defaulting to 4.0.

As has been said by others: The level depends on the max. bitrate and resolution. For best playback compatibility it should not be set higher than absolutely needed. Every 4.1 compliant player/device will play 4.0, but not vice versa.
Because you re-encode your original blu-ray with a lower bitrate the level is automatically reduced from 4.1 to 4.0 by BD-RB.

[rax_y]

Sharc, if that is the case. How come I am seeing this when I change the mode from Movie only backup to full backup using the same source?

"C:\Users\xxx\Documents\BD_Rebuilder\tools\x264.exe" "E:\MISC\BD REBUILDER\WORKFILES\VID_00000.AVS" --preset medium --bluray-compat --b-pyramid none --weightp 1 --qpmin=0 --bitrate 4825 --level 4.1 --qpfile "E:\MISC\BD REBUILDER\WORKFILES\VID_00000.CHP" --sar 1:1 --aud --nal-hrd vbr --pic-struct --vbv-bufsize 13000 --keyint 24 --min-keyint 1 --ipratio 1.1 --pbratio 1.1 --vbv-maxrate 15000 --threads auto --slices 4 --thread-input --stats "E:\MISC\BD REBUILDER\WORKFILES\VID_00000.AVS.264.stats" --pass 1 --output NUL

[Sharc]

Well, just guessing:
When you do a full backup the encode is supposed to be burned to a disc which will be played on a Blu-ray player which supports level 4.1, so it's a matter of blu-ray compliant encoding.
When you encode to Alternate movie only it's likely that the file will be played on any device like a mobile phone, tablet etc. which may not support level 4.1. but 4.0 AVCHD only. You don't loose anything with 4.0.

[rax_y]

OK. Thanks
