please help LPCM audio pleade help

[deedogz]

After converting to DVd using main concept i hear no audio.

i'm the NTSE area so that mean i should use LPCM audio mode or should i use the layer 2 or layer 1 which one?

if it's true i do have to use LPCM audio mode do i need a codec for hear shoud and where can i get it if anyone know please

[erayboul]

If I'm not mistaken Main Concept is a MPEG-1/MPEG-2 encoder only and does not author DVDs. What files or files did you feed into Main Concept? Did you configure Main Concept to output a program stream (a single MPG file that has both audio and video) or elementary streams (separate files: probably m2v for video and wav for audio)? What are you using for authoring your DVD? It's possible that your authoring program requires elementary streams but you only provided it a video file.

Please provide more details about your encoding and authoring process.

The DVD standard for NTSC, by the way, is for 48kHz, 16-bit WAV files (LPCM) or Dolby Digital AC-3. Apparently many NTSC players in Region 1 can also play MPEG 1 Layer II audio (MP2), but that is not standard in the NTSC area.

Sorry about my first post i mad a mistake.
After converting to DVD the audio is still there.
after joining with TMPGNCE my two file (which i have convert to DVD with main concept)
only then after the joining process there is no audio when i play the file.

MainConcept is a find product and a HQ MPEG encoder. I like the program althought I haven't used it that much. The program will select LPCM by default but I always changed it to Layer 2 (MPEG-1 Audio Layer2) to save space on my DVDs. There is a big difference in file size between those two types of audio compression and I can't tell any difference in the sound myself.

You can also click on the "Details" button then "Advanced" then "Audio Settings" tab and specify a bitrate. I generally use 256k for movies and 224k for general stuff.

Good luck.

Ok, in Mainconcept You would load your AVI file for convert. Click "DVD", then click "Program(Video+Audio), NTSC, then Layer2. Then convert. There are other setting I generally change but these may not be necessary.

Joining files in TMPGEnc. I know you already know this. File, Mpeg Tools, Merge&Cut, add files, set file name, run. Pretty easy.

I would make sure my converted files played good before the merge step. Did you try to DeMultiplex on of those no/sound files to see if it actually had an audio stream? It's the tab next to Merge/Cut.

Good luck.

What version of the encoder are you using? What are you using to play the final files?

Previous versions of the mainconcept encoder did not produce true LPCM files, so that may be the case (your player isn't playing the audio because it really isn't true LPCM audio).

[deedogz]

part one of my file is fine when encode with main concept also part two
Before marging i open the file in media player to see if i hear sound which i do only after using tmpg to marge them the output file tmpg give me as no audio just video.

I'm using the latest ver of main concept i think is 1.04.01.
no i did not demulpex the output file tmpg marge gave me should i try it when know i dont hear any audio just to see if it as audio

This is the guide i'm trying to follow
http://ness888.users.btopenworld.com/fromvcd2dvd.htm

Everything goes good until step 2
When step 2 was done i got a file with video and audio but the audio did not match the video

So I start doing step 3 then step 2 which that gave my the file with no audio

Now I think I'm starting to understand what your trying to do.

You have 2 VideoCD disk you are trying to rip to mpeg, merge them together to create 1 complete file, then convert with MainConcept to DVD standards then author with DVD Author and create a DVD movie. Right!!! yeaaa...

Ok, your VCD are fine for DVD as is except for the audio. It's 44.1k and Tmpgenc DVD Author requires 48k audio. If you don't try to convert these VCD files (other than rip them of course) DVD Author will convert the audio for you when you create the HDD folder of your DVD Project. That program can and will convert audio, but it cannot encode video. ok

Many people converts the audio manually before going to author. This can be done by DeMultiplexing the streams in TMPGEnc, converting the audio to 48k (tmpgenc can do that too), then multiplex the streams back together. Done.

To just put those VCDs on DVD I would rip as the guide says, test the files, then author to DVD with DVD Author. You don't want to reencode them with MainConcept unless their like SVCD 480x480 MPEG2. Then you will.

You said they had audio sync issues after being merged but that was after being reencoded right? If you've got a sync issue then you need to establish if it's offset or progressive. Offset = off the same amount throughout the file, progressive means it may be good at the begenning and off at the end. Decide that and get back. ok

Good luck.

After ripping the file from the bin/cue
That was step 1
Step 2 marging after marging syne issue (good in the begaining torward the middle and end sync issue

[deedogz]

So should i follow the guide all the way even know after step 2 when i test the file i have sync issue?

[bottle-necked]

That sounds like a progressive sync issue. If the video was in sync on the original disk (VCD DISK) and now has this sync problem then it might be a resample problem. Heres a link to a guide for fixing that.

I would repair each file (sync issue) before the merge or the author steps. Fixing 2 outosync videos merged together would be a bummer.. haha

Ok now just encode both file with main concept both play fine and both are eccepted by tmpg dvd author program but the file is over the limit of 4.7gb

i thought main concept will encode the file to where it will fit on a DVd

may if i marge them then encode then maybe main concept will brake the file size down so where it can fit will it????

[bottle-necked]

NO...... most defently not.... lol Not after all this.. haha

Download DVD Shrink and shrink that project hard disk drive (hdd) folder to fit a DVD. The program is easy to use and works good.

Just tell DVD Author to ignore size limit and to create the hdd folder anyway. The program will do that, then run DVD Shrink on that folder.

That's the easiest way.

go for it....

[bottle-necked]

Ok, you said MainConcept should of know how to encode those to fit a DVD, well --- no. The program encoded those videos at the bitrate and settings that are programmed in that 'dvd template' it's using. To ensure your project would fit a dvd you would need to calculate the bitrate you could use based on how much time in minutes you wanted to put on a dvd, then setup the program that way. IT probably sounds hard but actually isn't once you do it a time or two.

But for now just shrink the project to fit with DVD Shrink and burn it with an RW rewritable disk. That way if something is wrong you can erase the disk and reuse it again. AFter everything is good then create an R disk.

GOod luck.

thanks i got it to work
