I have encoded a kvcd with no problems using just TMPGenc but when I do the sound it seems to have a slight distortion to it when played on my standalone player.

If I were to encode the video with no audio in TMPGenc is there a program I could use to mix the video and audio (wav) or any idea as to why sound is slightly distorted?

The accepted practice around here is to separate the audio and video, and then multiplex them at the end. To do this you need to:

Extract the audio into WAV format from your AVI source, using VirtualDub.

Convert the WAV into MP2 format, using BeSweet or HeadAC3he.

Mux your MP2 audio with your M1V video, using BBMpeg.

Many of the guides here will go into more detail (BlackPrince's DIVX to KVCD is a good one, as is Red-M's KVCD from scratch) with regards to program settings, but these are the basic steps.

Thanks for the reply but still get the same problem.

I used highest rate audio pcm for sound when capturing as is only one that seems to show in virtual dub as having 16 bit sample precision. When I play back recording it sounds a little better but not much.

I took out my Yamaha XG sound card and tried the on board AC97 audio but is exactly the same.

I have an XP1800 Athalon, new hard drive, 256 Mb memory and Pinnacle TV capture card (although my original card a few months back had the same problem with distorted sound). Any ideas?

It is like a small distortion, almost as if a slight tinny distortion sound is added yet I have this only with captures, whatever tv card and software I use.

Help!

Thanks )

Ok, so, have you actually tried to playback the sound via Standalone DVD Player or just on your machine?
I used to have a computer, where (due to some weird hardware conflict) I could hear the machine working through the speakers I know it sounds weird, but whenever the harddisk of the computer was working, my speakers made a sound that sounded like distortion...

Well have you checked downsampling to 44.1 khz in Headache too?

I have tried all my kvcd`s on my standalone player as I don`t play dvd`s or vcds on my pc anymore and they sound the same whether I convert the audio or not. I did some searching before posting here and found some posts via googles search engine of people elsewhere having the same problem but none had it resolved.

I love the KVCD format and browsing the forums, and I definitely appreciate the help here and won`t continue to post questions a lot but being new to it all I am learning very quickly.

Am I right in thinking that when Virtualdub shows an avi has a sample precision of 8 bit that means the sound itself is only eight bit

Anyway, thankyou very much for being patient with a kvcd newbie (not a computer newbie though) and I shall continue to browse the forums and see what best settings, etcetera, are.

Thankyou
