Ignoring 2 Pass and Dual Audio
Hi Folks,
I am struggling to get an MakeMKV BD rip transcoded the way I want.
For some reason, HB is ignoring 2 pass and dual audio.
Here is a pastebin of the source file, HB command line, and output files shown in avconv and mediainfo.

What am I doing wrong?
Thanks in advance for your help.

Re: Ignoring 2 Pass and Dual Audio
Could you please post your encode log as well.

Re: Ignoring 2 Pass and Dual Audio
Is the encode log kept somewhere in particular, or do I just copy and paste the terminal command line output from my screen?
I shall have to redo the test encode if it's not saved anywhere.

Re: Ignoring 2 Pass and Dual Audio
Got it, thanks. I shall do that soon and post here.
Re: Ignoring 2 Pass and Dual Audio
You're not setting a video bitrate; the default rate control method (constant rate factor) only requires one pass.
You're passing two audio encoders and audio bitrates, but only one audio track; try --audio 2,2

Ah, that explains it, thank you.Rodeo wrote:You're not setting a video bitrate; the default rate control method (constant rate factor) only requires one pass.
I have watched the 5 min test and it is great quality, so I'm happy to ignore the 2 pass.
Is that OK to do?
Is it really worth the extra time?
Ah, I shall try this now... third time lucky!Rodeo wrote:You're passing two audio encoders and audio bitrates, but only one audio track; try --audio 2,2
Re: Ignoring 2 Pass and Dual Audio
No, constant RF (single pass) is the way to go (you may adjust quality via the -q option). Only use 2-pass if you must use average bitrate encoding for some reason.

Re: Ignoring 2 Pass and Dual Audio
Bingo, problem solved...
--audio 2,2
Thanks!

--audio 2,2
Code: Select all

[17:58:32] + decoder: English (DTS) (5.1 ch) (track 2, id 0x2)
[17:58:32] + bitrate: 1536 kbps, samplerate: 48000 Hz
[17:58:32] + mixdown: Dolby Pro Logic II
[17:58:32] + encoder: AAC (libavcodec)
[17:58:32] + bitrate: 160 kbps, samplerate: 48000 Hz
