Tmpgenc Encodes to MPEG-2 with No Sound

[Maynard123]

I captured the MiniDV source tape to an AVI file, edited it with Video Factory 2, creating another AVI file, and it looks great.

I then encoded the AVI file to MPEG-2 using tmpgenc, but the resulting file has no sound. As a work around, I encoded the AVI to MPEG using Ulead Movie Factory (and burned to DVD), which worked perfect. However, I don't think the quality is as good as the tmpgenc encoding.

Anyone have any ideas why I might be losing the sound with tmpgenc?

Thanks for any advice you can provide.

If I try to encode an AVI file that has VBR audio with TMPGEnc, often times it will have no sound. When that happens, I open the origional AVI in VirtualDub and set the video to direct stream copy and audio to full processing then save the avi. After that, I have always been able to convert the new AVI file to MPG2 with audio.

Thanks Howard, I'll give that a try!

By the way, is it possible that Tmpgenc would produce an .m2v file with no sound, and simulaneously produce a .wav file with the sound?

Thanks again.

Yikes, sorry about the newbie stuff, but I realized that I did create an .m2v file and a .wav file with tmpgenc.

However, when I use my DVD authoring/burning program, Ulead MovieFactory2, it doesn't seem to have a way of importing two separate files, just the .m2v file.

Thanks for any advice.

I noticed that too about Movie Factory. There is however a place to specify a wav source to use. I'm not sure how to get Movie Factory to pick up mpg audio sources if you sperate the video and audio streams. Movie Factory may have a way to specify the mpa file but I did not see it when I needed to do that.

That is one of the reasons I started using DVD-LAB which I plan to buy once my trial period expires.

You can have TMPGenc encode in either ES (m2v + mp2) or PS (MPEG file muxed with both video and audio). The DVD template defaults to ES, but if you look in the bottom left corner (abov the load/save/edit buttons) you can choose the output format.

Let me also add that you might not want to author your DVDs with wav (uncompressed PCM) audio. The reason is that uncompressed audio files are huge. It's often possible to get a higher video bitrate but encoding your audio to ac3 (eg. w/ besweet).

You can also have TMPGenc output mp2 audio, however not all NTSC standalone players support mp2 audio streams on DVD (the vast majority do, but not all).

Thanks for the great advice guys. It sounds like I have some options, and you have solved my problem

I take it AC3 is more widely compatable with set top DVD players then mpg2 audio? Does it compress down as much as mpg2? My player is fine with mpg2 but I'd like to learn how to make my DVDs compatable in case I run into an odd ball player some day.

I downloaded Besweet but haven't fiddled with it yet.

I created a DVD with MPG audio which plays fine in one of my Toshiba DVD players (about 2 years old) and doesn't play audio in another Toshiba DVD player (about 3 years old). I haven't tried AC3 yet.
