Low Quality Audio, High Quality Video

[punkster103]

Every time I try to encode something with TMPGEnc on any template, and burn onto a SVCD/VCD and pop in my Pioneer DV353, I turn the TV up very loud and it seems as though there's a weird echoy effect, and it sounds very bad. Anyone know what the problem(s) are/is? I extract the audio with VDub, and encode with TMPG 2.58.

In the TMPGEnc Audio settings Choose 48,000KHZ and 128KB/s..see if it works...because I think you might be converting your movie in a low Audio Bitrate

have you checked the source audio file "BEFORE" you encode with tmpeg, with a program like cooledit or sound forge?? What is the original source file? .wav, .mp2, .mpa,.ac3 ??
Remember, shit in, shit out!!

It's a DivX file, I extract the audio from it with Vdub, save it as an ucompressed .wav file. I thought I already noted that..

Thanks DivXerouS, I will try that.

punkster103: The built in audio encoder in TMPG isn't that great especially when it has to change sampling rates. The best thing for you to do is to download Toolame and set up TMPG to use that as the external audio encoder.

If your audio sounds like people are talking through a metal pipe, it's probably the sample rate converter in tmpgenc. It doesn't always do a very good job. For best results, you should probably use ssrc or besweet for sample rate conversion (I have tmpgenc configured to use ssrc automatically), and toolame or some other external MP2 encoder.

48kHz isn't a "legal" sample rate for VCD/SVCD, but it will probably work. But the difference between 44.1kHz and 48kHz probably won't be that major. 128k is probably too low for good MP2 quality. I never put the audio below 160k, and most of the time I keep it at 224k.

You are correct the legal limit is 160KB/s and lower than that might not provide good quality...BUT ! in the Audio settings, Channel mode Set it DUAL Channel because I think you are converting it in Stereo mode...because I converted a movie at 48KHZ 128KB/s dual channel the sound came out pretty good..Try that it might work...
