[b]converting avi to DVD audio problem[/b]

[Shamone MO FO]

Hello All,

I've come to tap into your fountain of knowledge again! lol.

I wanna convert an avi to DVD. I'm using TMPGEnc 2.5 Plus I successfully did this but the audio was a little shoddy and out of sync. I've converted the avi to MPEG VCD and this was fine so I know the original source must be ok.

I used Virtual Dub to rip the sound to a WAV file and then TMPEG to convert to DVD but I noticed the sound was 48000 ....is this correct for DVD?

If this is not correct ca someone tell me how to use VD to rip the sound to the correct rate.

I was well impressed with the video quality though!

What I have done is demultiplexed so I have the video file now woth no audio so hopefully i can just multiplex the correct sound back in with the video - any suggestions on this too?

Please help!

Thanks in Advance!!

Hi Shamone MO FO,

Yes.

Where's your AVI from? Mine is from when I transfer from DV cam to PC. See this link:

...for the steps I take to go from DV cam to DVD disk with menus and good quality. I don't claim it's the best way or the right way as there's loads of ways and loads of different tools. But it will give you a good insight into what you need to do, typical tools and settings.

If your aiming to get over (approx.) 100mins onto a DVD, you'll either need to reduce the quality (by reducing the bitrate, see below) or keep the quality and split the output on more than 1 disc.

A bitrate calculator is used to tell you what bitrate you need to use either:
1. As a max for Constant Bitrate encoding - CBR, or
2. As the average for Variable Bitrate encoding - VBR (as I use in the link above).

A good one is the DVDRHelp Bitrate Calculator, but there are others in the Tools section.

Hope that helps. Good luck - It's a minefield and seems hellish at first, but the effort is worth the reward and the satisfaction.

Thanks Daamon!

Another friend of mine told me that is most likely that the original source is NTSC and I'm converting to PAL so maybe thats the answer! I'll try converting to NTSC!

All update this thread too if anyone else encounters this problem!

Hi Shamone MO FO,

No probs.

Use either / both of Gspot and AVICodec on your AVI to give you loads of info about the video, audio and associated codecs.

NTSC to PAL is possible (I've never done it). There are guides to the left that will help you, but I think it's fairly involved.

Keeping it in NTSC might be OK, but only as long as your stand-alone DVD player (I'm presuming that's what your using to view) accepts and plays NTSC - some do, some dont. It might say in the "DVD Players" link to the left.

Good luck.

Ah well tried that and it didn't work. I am determined to master this and I am still soldiering on so I'll let you know when I have ....See you in a year or two! LOL

Hi Shamone MO FO,

Ah well tried that and it didn't work.

What exactly did you try and what was the actual result?

What did either of GSpot or AVICodec say about your AVI, particularly the audio?

If it's the (original) audio problem, it might be that VirtualDub isn't a fan of the audio format (identified above). I know that there are other "flavours" of VirtualDub - one of these might be the one to do the job.

Posting specific details / results will help...
