No sound mainconcept

[snatch69]

just done a re-install of xp installed guardian knot codec pack and main concept , now when i encode i get no sound on the output file, any ideas??

Double check you gordian knot settings and make sure you have the proper audio files installed.

There is are step by step procedures here: http://gordianknot.sourceforge.net/

Mainconcept can be a pain in the ASS when it comes to sound. It's a known glitch - but there's no known workaround.

Sure there is.
Extract audio to .wav in virtualdub.
Use that .wav as audio source in MCE.
(Only if you must for your authoring application).

Actually that is NOT always a fix.

My method of converting:

1. Demux AVI in virtualdub.
2. Load WAV and sound-less AVI into Mainconcept.
3. Encode

But half the time the sound would disappear in the middle... and when that happened, usually NOT demuxing would make it work ok - just load up the original file.

Conversely, sometimes when the original file made an MPEG with no sound, I'd demux and THEN it would work.

Like I said, Mainconcept has audio issues - the times when it failed, there was no log entry, no warning, no error - it just finished up the encode and made an MPEG with no sound.

I agree. MainConcept is really a pain in the ... you know where !

I have tried to encode so many AVIs / mpeg1 / mpeg2 / experimented with separate sound etc etc ... with MC but somewhere down the line MC screws up with sound.

snatch69, dump MC and go for TMPGEnc. It may be slow but it will get the job done.

I don't agree with the asessment. There are issues with the encoded (downloaded) files not with MC Enc. Never failed here. Sound is often encoded to a God knows what piece of crap that MC is not happy with. It does what it does and it does it pretty well but you cannot open a can with it. Call it a "bug". It wasn't obviously designed to do what you want it to do. There are apps that are; use them or learn how to deal with your audio issues.

Proxy:

Here's the problem - I convert that audio to a WAV. There's no such thing as a "poorly encoded" WAV. It's raw, uncompressed, WAV audio.

And Mainconcept... well, just gives up partway through sometimes.

It's replicable, it happens all the damn time. I love Mainconcept, don't get me wrong. But when it fails, it fails - and there's no error. I'd be PERFECTLY HAPPY with it saying "hey fix that audio file", but frankly I have no idea HOW to "fix" a WAV anyway. If it's uncompressed WAV data generated by Virtualdub, how exactly would you propose that I provide "cleaner" data to MC?

[proxyx99]

Obviously if it is extra clean then the issue is combining A and V where properties of both may not match at some point. Ever thought about that?Seems that the problem is more complicated than what you seem toi suggest considering the fact that MC is a pretty capable app.

In case of potentially incompatible/problematic source encoding to elementary stream is much better. Why load wav during encoding, you can mux afterwards. MC can recode audio separatelely as well so you can save yourself extra aggrevation. Other then that MC is a damn good, robust and effective encoder. I always consider the source while assessing the best way to complete the project. Poor source always means trouble, one way or the other. You know that. How many times MC has failed you with a good source like a DV or good MPEG stream? Not once in my case. Problems with encoders always have to do with source corruption or degradation. Internet stuff (that we are talking about) is well known for that. As I said, with a decent source MC is just great, never failed.

Exactly. Don't blame MC.
Tmpgenc may just have the same issues, and it's easily twice as slow or more.

[Gurm]

Oh, I'm not saying MC isn't capable, and yes I've ended up doing them separately and remuxing afterwards. And you ARE right - it tends to ONLY happen when doing DIVX/XVID video, not "cleaner" AVI codecs or good clean MPEG source data.
