Capture to 2 channel Dobly Digital AC3

[Kairo]

Ok, Im going to try and keep this short. Is it possible to capture (to) 2 channel Dobly Digital AC3 in "ATI Multimedia Center" or "VirtualDub". I do want to make it clear so there is no misunderstanding, Im not wanting to caputre from a Dolby Digital or DTS source. Im wanting the resulting captured file to contain a Stereo AC3 auido track as this would save me alot of editing time.

There's an AC3 version of Virtualdub that's supposed to do that...Not sure if it works.
If you have an AC3 encoder, then vdub should use it, if you choose audio compression.

I'm not sure that the AC3 codecs available work like that... They are usually Decoders, NOT Encoders. The AC3 encoders that do exist usually want you to input another file format such as WAV or MPEG. You may be stuck with having to capture in either WAV or MPEG, and then converting afterwards... 8)

Duh! Sheesh I was blonde there for a bit.
Try your capture in Nerovision Express 3, it will encode AC3 on the fly.
I don't know about any others, except the expensive stuff.

Thanks reboot Im going to try Nerovision Express. I had the app for a long time and never used it. But I am wondering in if there is a codec that exist that allows for AC3 encoding and not just decoding? I have many AC3 decoders. What Ive been doing is capturing the audio to uncompressed PCM then latter converting it to DD with BeSweet. I was hopeing there was a way I could skip this step altogether. Oh well, Thanks again reboot.[/quote]

Most AC3 encoders are expensive addons to other apps. I haven't found one yet that I could possibly bother with, or afford.
I was rather hoping that the tmpgenc ac3 addon would give me some ac3 encoding support for capture, but that was too much to hope for.
I usually rip to .wav and transcode in ffmpeggui (easier than besweet, but uses the same engine).
I have found that it's output volume can be very low, so I usually double (approximately) the .wav volume in Goldwave, save .wav, then transcode.

This has little to do with my previous post but... This is to reboot. I have ran into the same problem with volume when dealing with Dolby Digital tracks. What I've concluded from my own experiences is that it quite possibly may have nothing to do with the file its self or the encoder at use, but the app/decoder that is in use when playing the track. Here is an example. Ive had a track that I ecoded with Nero Wave Editor that when played in Windows Media Player and WinAmp seem to have a very low volume. But when I play the same file (without changing any default settings) in VLC Media Player or PowerDVD or on a standalone player it has the same volume as the file I started with before I converted it. This would lead me to believe that its a problem with the decoder the player is useing. Not sure if thats why? Oh, just to save myself from posting again. Does DVDLab have a steap learning curve? Ive never used it or read much on it. Is it a better program then Ulead DVD Workshop 2? Thats what I'm useing right now. I want to be able to use multiple DD 5.1S audio tracks, subtitles, and Progressive Mpeg2 in 16:9 Widescreen format. Thanks in advance.

First, I think it may only be my standalone player that sees my recorded AC3 as low volume. The files play on the computer just fine.

Second, yes, DLP does have quite a steep curve, but for what you want to do, there's nothing better, and it's miles ahead of Ulead stuff.
Start with the guides.

Readers should note that ffmpeggui and besweet do not produce 100% DVD compliant AC3 files, so any problems you have, could be due to this...

[reboot]

The only problem player (so far) that I know of with ffmpeggui's ac3, is the cyberhome...but evidently it has problems with all sorts of things, not just audio.

My old Pioneer DV343 (and the DV434 I believe) won't play anything with AC3 from ffmpeggui/Besweet.
