Maestro/Spruce Up & Inconsistent Bitrate AC3

[anders@dac.se]

i've ripped two logos from two diffrent dvds,

i get these error when including them in my DVD autering program..

Bit rate are different between "AC3 Audio "dolby AC3 T01 3_2ch 448Kb""(448000) and "thx AC3 T01 3_2ch 384Kbps"(384000).

it looks like i need to change the bit rate, so i downloaded BeSweet and AC3Machine.

this is the command that AC3Machien sends, and the answer i get from BeSweet...

I have BeSweet 1.3 and BeSweet GUI and AC3 Machine. I cannot figure it out.

I have the audio demuxed in 2 ways:

rules AC3 T02 3_2ch 384Kbps DELAY -66ms.ac3 <<< done by DVD2AVI but is a VBR AC3 and DVDMaestro squawks

vts_02_([0x81]_Audio_English_AC3(6Ch)_48kHz___)_Delay_-67ms.ac3 <<< done by SmartRipper but the bitrate is WAY too highyou need to re-encode your second stream with AC3Machine to bitrate of 384.
then, you might wanna join the two tracks with BeSweet (read FAQ).

[KeithXP]

DSPguru,

I must be doing something wrong. Here's my command:

"BeSweet.exe" -core( -input "F:\Rules\vts_02_([0x81]_Audio_English_AC3(6Ch)_48kHz___)_Delay_-67ms.ac3" -output "F:\Rules\Output.ac3" -logfilea BeSweet.log ) -azid( -c normal ) -ssrc( --rate 48000 ) -ac3enc( -b 384 )

I start with an .ac3 file that is 427,966,768 bytes large and end up with a 122,268,800 byte .ac3 file that does not load in DVDMaestro. I get a Media Detection Error when I try to import it. It also plays back just noise.

Help,
KeithXP

Thanks but that did not work either. Same thing. Same file siz and Media Detection Error when importing into DVDMaestro.

Help!

[pacohaas]

browse the forum a bit (http://forum.doom9.org/showthread.php?s=&threadid=32277)

[KeithXP]

Thanks pacohaas,

Let me post something that may help someone after me. Here's what I found:

If your DVDMaestro screams you have a high bitrate, use AC3Machine and lower the bitrate of your .ac3 file. I did a search for AC3Machine and looked at most of the topics, but I should have searched for BeSweet because you need it. Here's the key:

BeSweet 1.4+ supports ac3 encoding. Don't even try any version before that!

If you're using the Robshot method to backup DVD's and you're to the point where DVDmaestro won't accept your .ac3 because it has inconsistent bitrate, then use SmartRipper or something of the like to demux your .ac3 file without using DVD2AVI, then AC3Machine that file as above.

I hope this helps,
KeithXP

I have been trying to import assets into Spruce Up (video & audio)

Video is no problem, but the audio is .ac3.

I keep getting the following message :-

Inconsistent bitrates were found among audio frames. Bitreate should be consistent throughout the stream.

I have tried changing the file extension from.ac3 to .wav to try and fool it, but no luck.

Unfortunateley, if I try and save the audio as a .wav file, it becomes to large to join with the video.

Any suggestions please ??

I guess as a last resort I could try and convert the .wav to .ac3 and see if that works ??

By the way, the movie is Pearl Harbor.

HomerJ

[pacohaas]

it may be a vbr ac3, you can use AC3Machine to reencode it to a CBR ac3.

[HomerJ]

pacohaas,

Thanks for such a quick response. It looks as if the problem is with the movie itself. (Pearl Harbor).

I did all sorts of "technical searches" i.e. .ac3 bitrate etc.....

As I wrote the thread, ending it with "pearl Harbor" I thought, "searh on "Pearl Harbor".

So I did.

Looks like chapter 45 is a "dummy".

So, I am just about to rip the audio minus chapter 45 and see what happens.

I'll keep you posted.

HomerJ :)

Hi

I have a problem with a ac3 file. I´ve created a ac3 file with dvd2avi and when i try to import it to spruce maestro, maestro gives an error and it says: "Inconsistent bitrates were found among audio frames. Bitrate shoul be consistent throughout the stream (0xc1070052).

Any ideas to fix this?? Wich is the best program to get a ac3 file like dvd2avi??

Thanks in advance.

P.S. The movie wich this happens its Pearl Harbour...

[alturismo]

same prob here with the ac3

cant imoirt into maestro, also when listening to it sounds very
strange.

what i thought, cause its an multi angel movie

may any help

thx ahead

[alturismo]

oki

solved the problem here now

it was the multi angel stuff

when i demux the tracks with dvd2avi, it doesnt seem to work with it,
also the d2v file is useless, cause it makes errors with the movie too (had after using that d2v file an movielength from 2.30h instead
of 1.35h, same with ac3)

what i did now, opened the "files" with smartripper, and demuxed
the audio there from "angel 1", and, that was it, ac3 fine now,

then i ripped "angel 1" from movie again and reencoded that one now,

and that was it, prob solved here for me with multi angel movies.

the movie im on is "liberty stands still"

may that helps some
