Before I convert the AVI to mpeg I demultiplex the WAV file, and then using the SCMPX I encode it to STD PAL VCD 44100Hz 244kbps stereo.
When I multiplexing the m1v and mp2 (from SCMPX) TMPGENC 2.59 always warned me that the mpeg is UNDERFLOW and might not be played.
I have found when I already made them a VCD, the sound is very poor with a click or something.
Anybody know how to repair my WAV file ?
It is a PCM 44100Hz 172kbps.

Thanks.

You will Not get that error if you Use SCMPX with Tmpgenc, You can Load SCMPX to be the Audio encoder for Tmpgenc, Go to Options" to "Enviromental Settings" to "Audio Engine" and Load SCMPX as the Audio encoder..Now you won"t need to Multiplex the audio to the video Cuz Tmpgenc will do it while encodeing and you will still have SCMPX to encode the audio..

Hello everybody ....
Does anyone know whether there is any way to timestretch an AC3 audio file and maintain all the seperate channels (such as would be done in Cooledit with a WAV file.)

Cheers

No Not with AC3, But you can convert the AC3 into a 6 chanel WAV file with HeadAc3e then use something like Cool edit or Sound forge to time stretch it then you would need to seperate all 6 chanels into 6 Mono wav files Cuz AC3 encoders only seem to accept Mono Wav Files and encode it back to AC3..But this is A very Long way to do it But I don"t know of any other way Cuz I don"t know of any Audio editing programs that accept AC3..

Here is a revision of a previous question that i have posted. Origionally i was concered with the output of a 22 minute divx file converted to mpeg-1 being about ( approx 1h and 15min ) 650 megs. Now after making many attempts at different settings i have found that the video is converted properly for the most part. But the last frame is frozen for the remaining tie of the video, and no audio has been added or encoded.

thanks Fenix

The last few frames must be corrupt. Two things you can do here, one is use the source range function to end the encode before the corrupt frame or use Virtualdub to try and fix the bad frames.

As for your audio problem use either AVImux or Virtualdub to extract the audio to a wav file and use that as your audio source.

I have been using TMPGenc plus version 2.53 with no problems. I used rip the DVD, use DVD2AVI and then load the dv2 file for video and the wav for audio. I've no problems. I recently downloaded 2.59 and now I am getting no audio, even though I have loaded the wav file. I tried suggestion of increasing the Direct Show priority (in the environment settings), but it hasn't worked.

Any ideas?

Ok, have you set the stream type setting to 'System(Video+Audio'?
If so goto Setting>Audio>Setting then click the play button. Can you hear any audio?

ASHY

hy,
I´ve the same problem, but I´ve the version 2.54.
Okay, so I´m went to settings>audio>setting. But now I see that I can`t click the play button, because the button isn`t deposits. I really don´t know what to do. Please help

Stanley

The reason you can't click the play button is because TMPG cannot decode your audio or there is no audio loaded.

Use virtualdub or AVImux to extract the audio to a wav.

ASHY

And than???
I mean I have a wav file and an mpg2 file. But how can I bring them together???
Or should I first take the wave file out of my avi file and bring them by the encoding together???

Stanley

P.S. I must fixed the Browse

Sorry, but my English isn´t really good, isn´t it???

Yes, extract the wav file from your AVI then load the AVI as your Video source and the wav as your Audio source then encode.

ASHY

oki, I want to proof this!
See ya in an hour or so! ty

Stanley

So, I get AVImux. I don´t know how to serv.
Where are you from????

Stanley

Virtualdub I`have too. Which is better???
I don´t know how to manage, please help me!

Stanley

AVImux is more reliable as it can extract Ac3 to wav also.

Follow these instructions:

Load the AVI into avimux. Uncheck the Video, highlight the audio then right click it. Choose 'Select compression' from the menu and select PCM. In the next box choose the default which should be 44.100khz, 16bit, stereo.

Click 'Output AVI' and name your output with a wav extension then click 'Go'

If you have audio problems such as the sound breaking up in the extracted wav set the 'Pre-roll' and 'Interleave' settings to 100ms.


ASHY

Sorry I don´t understand your explanation

Hi,

I used DVD2AVI and there should have been 2 files saved (I believe) .d2v and a .wav file. I can only find the .d2v file. There is no .wav file. What am I doing wrong?? There are also 4 files with the extension of .ac3 and I have no idea what these are for. This is my first time doing this, so any help is greatly appreciated. (By the way, I'm using the DVD Rip guide that was is located on www.dvdripguides.com)

Thanks!

Denice,
The ac3 files your getting are your audio streams (1 per language in the movie). Depending on what you're planning to do you can go ahead with them. If you absolutely need wav files, you have to select the "output to wav" option (or something like that) under the audio tab of dvd2avi.

You have selected the wrong settings in DVD2AVI. Choose the settings as follows.

1. Click 'Audio' then 'Track number' and select 'Track 1' from the menu.

2. Click 'Audio' then 'Channel format' and select 'Auto select'

3. Next click 'Audio' then 'Dolby digital' select 'Decode' and 'Dolby surround downmix' from the menu.

Now create your d2v again and you should have a wav when finished.

Hi I found the angle potion codec on my machine and removed it. This elliminated some of the pink color from my MPEG-1's There's still some there.
I got this post from a different question about the pink color: "Have you Tried Raising the Priority of the "Direct Show File Reader" in the "Vfapi Plugins" to "2"?" Mine under the enviromental settings is set to 0 but it's uneditable. Can someone please help me change it to 2 ? I can't figure out how to do it!
Thanks,
Lisa......


--------------------------------------------------------------------------------

Right button click and select higher priority. This will add 1 to the value so if you want to add to do it twice.

Rick

Thanks Rick!
Will have to run another test to see if it makes a difference.

CPU useage on a processor system will be at 100% for both processors when not using the 'Noise Reduction' filter. When 'Noise Reduction' is used (makes VCDs look great BTW) the CPU useage drops to around 50% for both processors.

Would be nice to have 100% utilisation when using the filter.

Is there any way to encode MPEG2 PCM audio instead? I am using:

TMPGEnc Plus 2.58.44.152, Core 1.90.140
For DVD MPEG2 NTSC compatible:
MPEG-2 720x480 29.97fps CBR 8000kbps, Layer-2 48000Hz 384kbps (with error protection)
DVD+R disks
DVD using DVD Workshop 1.3 for authoring (w/do not re-encode)
Use a lot of WAV audio when editing DV, then authoring to AVI before suing TMPGEnc

Got any suggestions, please? PCM is more compatible in more stand-alone DVD players, right? Thanks.

It is Not nesessarily More compatible..Most players will Play MP2 and WAV audio and Dolby Digital AC3 audio...With the 2.59 Version it will let you out put the audio to Wav but I don"t think it Muxes the audio to the Video with this Option, I think it gives you a Mpeg Video file and a Seperate WAV file..

PCM audio may not even be a legal audio format for mpeg files.

To get PCM on a DVD you load it seperately from the video into most authoring tools.

It is annoying that you can't have an mpeg file with uncompressed audio, especially for music performances.

Thats too much time, so I am forced to encode using "estimate" in Motion Search. Then, using "estimate" search, I can encode a 50 minute movie and it takes only about 2 hours. I've used TMPGEnc before on "High" and it took only about 6 to 8 hours, but now with my new HHD, it says it will take 20 hours. I've never let it go ahead and encode at "high" because I don't want to wait 20 hours. I'm using:

TMPGEnc Plus 2.58.44.152, Core 1.90.140
For DVD MPEG2 NTSC compatible:
MPEG-2 720x480 29.97fps CBR 8000kbps, Layer-2 48000Hz 384kbps (with error protection)
DVD+R disks

When I encode with "estimate" search and author using DVD Workshop 1.3 with "Do not Re-encode", I get a good DVD movie disk that plays on my stand-alone DVD player, but the vidio is a bit jerky, not real smooth. I've tried 2-Pass VBR (8000, 6000, 5000) with "High" motion search, but again it says 20 hours or about, so I don't go ahead and encode it... too long time.

QUESTION: why so long time on "High" motion search? Or, is the program not telling the truth and it will, if I go ahead, only take 8 hours instead of 20?

You should Be able to get good Results just useing the "Normal" setting..But stay away from the "Highest" setting Cuz that will take forever...If you wait for a While the encodeing time should go down a Bit, But if you want to encode fast then use a Faster encoder..

There are a few things that will effect how fast you can encode. On the hardware side is the cpu speed (the faster the better and P4s are the better choice of the intels), ram (more the better), disk access time ( SCSI U320 probably the best single drive but raids of scsi is better and ide raids are good, Single ide start at ata 133 and go down as well as rpm and buffer size play a role. Software, if the drive supports DMA make sure it is turned on, shut down software that runs in the background such as Nortons System works or other virus software that might be monitoring the system constantly. I only encode SVCDs from Dvix and average 2 hours for every hour of movie at the highest quality setting. I have a 47" widescreen and that higher setting does seem to help. Hope this helps.

Rick

I doubt that the 'Motion search' setting is in any way connected to your jerky playback problem.

There is more likely something else causing this.
Have you set the 'Field order' abd 'Frame rate' correctly?
What are the details of your source file?

Secondly '2 pass' is not a good setting for encoding DVD.

If the source is reasonably good quality you will get better results in a much faster time using the VBR method 'Constant quality(CQ)'.
This is also similar to the VBR method CCE uses and, as anybody who knows anything about encoding will tell you, you can't beat CCE for quality.

The 'Motion estimate search' setting will give you good results if not identical results to the 'High quality' setting as long as the source is decent and shouldn't affect the playback.

Also I don't think it is necessary to set the Minimum bitrate so high.
