Hi Jorel, I will keep bitrate the same 384.

Seeing as BeSweet via PS gives me this freezing error in playback on my Standalone DVD player I just wanted to encode the audio from an external encoder.

Im not to sure if I can simply use the ac3 file generated by DVD2AVI or do I need to use AC3Machine or another tool to re-encode or to clean up and avoid the quiet volume issue as Inc mentioned.

yes, you can use the ac3 file extracted from dvd2avi!

The file you get from DVD2AVI is _exactly_ the same that you hear when you play the original DVD in your standalone. As jorel said, use the original track, don't re-encode.

@Jorel & Boulder

So this means really even if my AC3 is 2ch or 5.1 I can just use the ac3 track extracted by DVD2AVI without the bother of converting 2ch AC3 to mp2.

This is excellent news guys I thank you both so much for your helpful info and same goes to Inc and Phil.

Thanks guys.

Out of interest if I did want fix an ac3 made via PS to avoid the audio being to quiet what settings would I need.

These are the current settings i have:

What should be the correct/optimum settings?

Thanks again guys.

"Fixing" an AC3 ??? Thats not the way!
Do use the orig AC3 or whatever and use AC3 machine inc. "Auto find max gain" as you showed in your AC3 machine settings.

BUT! Some parameters in Besweets engines did change! And so I would use Packshots generated Besweet commandline but in azid a "-g max", this will make the ac3 encoding louder.

BUT as AC3machine ALSO like Packshot bases on the ac3enc.dll ... then you will end up with the SAME type of AC3!
So do first look if ONLY issues do occur if your Player gets 2.0 CH reencoded AC3s.

If there still problems do occur (on my player they doesnt) ... you should use in DVD decrypter "demuxed" streams output where you go into packshot using the resulted m2v from dvd decrypter and the outputted AC3s you can reencode (If wanted) using SOFTENCODE ... which is known as one of the best AC3 encoding apps. ---- but it costs money!

Note: I have made an amendment to the topic title as suggested by Inc.

Since I now know that the freezing issue was caused by the audio and not the video it makes better sense for others to not to be mislead by topic title.

Thanks again guys for all your help.

Adding:

Its also senseful as for audioencoding BeSweet is used in Packshot, and DSPguru WON'T that it could be seen that ac3enc.dll is a fixed part of Besweet! Its just a standalone.dll independend from DSPgurus developement - Thats also the reason why he wanted me to add that "warning message window" if AC3 encoding is choosen in Packshot.



And a resumeé is that this issue above is Player-Brand/Model/Type dependant!

Thanks Inc, I fully understand that ac3enc.dll is an external part of both PackShot and BeSweet and hence im not blaming either products for my ac3 problems.

I dont know if there is a bug in the ac3enc.dll and if there will be any updates of it to address the problems it has.

Hi Michael!

AC3enc.dll related very useful links!!:

http://forum.doom9.org/showthread.php?s=&threadid=43466

http://forum.doom9.org/showthread.php?s=&threadid=52263

As you can read there the incompatibility issue "should" have been solved and thats why a new ac3enc.dll came out (which in regular is in the latest besweet package included!) ... so do check your ac3enc.dll version.
Also there seemed to be only an issue related to player crashings when encoding to AC3 2 CH.

Volume related .... well as said, do use in Packshot in case of AC3 Gain = Auto which gives the right parameter to azid ( -g max ) which avoids only 50% volume on AC3 outputs.

In one of the threads above (at the end) you can see a post from J-Wo who said that a ota ( -G 1) "postgaining" (not pregaining!) instead of azid (-g max ) would give even louder AC3 outputs ... I'll check that.

Thanks for the links and info Inc, I shall read them.

As the the ac3enc.dll I downloaded it at the same time as PackShot as you suggested when you first released PS on the 15/5/04.

So basically I dont know when was the last time ac3enc.dll was updated but im sure my is the current release I got it from DSPguru's site in the plugin section.
