  1. Hi, I have been experiencing a noticeable popping sound in certain parts of the audio of my DVD mpg files. This problem only seems to occur when the file is multiplexed, when I play either the source .wav or split .mp2 file (or even the audio portion of the captured .avi for that matter), it sounds perfect. It also seems to only apply to DVD files, as the same file encoded as an SVCD is perfect. I believe that I may be incorrectly configuring TMPG for DVD encoding, but I am not sure where as VCD's and SVCD's work great. Here is a summary of the process I use:

    1. Capture from camcorder using SCLive;
    2. Write AVIsynth script utilizing selected filters to clean up VHS;
    3. Open script in VDub;
    4. Save audio to .wav file;
    5. Open .wav in Cool Edit to remove hiss;
    6. In VDub set audio to 'No Audio';
    7. Start frameserver;
    8. Open frameserved file in TMPG;
    9. Select .wav file as audio source;

    Aside from the encoding rate (CQ 1000-max 5k, min 2k, enable padding checked), I am not changing any of the settings of the DVD template in TMPG.

    A couple of things I have tried:

    - Demuxed the mpg to get the video portion, then used tooLame to convert the .wav to an .mp2 and remuxed;

    - created an alternate script with no filters, opened it in VDub and re-saved the audio to an alternate .wav, then converted this twice, once with tooLame and once with TMPG, created two additional remuxed mpgs.

    What I noticed with these alternate files was that I still heard pops but this time at a different point in time of the video.

    Aside from a few loud pops, the audio and video are perfect and in sync.

    I suppose I will probably have to try re-encoding the video with no audio and mux them afterwards, but I am trying to get around that as it takes a very long time with filters. Anyone have any ideas as to how I can resolve this?

    Thanks in advance for your consideration.

  2. Actually, it turns out the problem was a specific filter, as re-encoding without it seems to have resolved the problem.

    Thanks anyway.

  3. What filter exactly was causing your pops? I am getting the same thing in a vcd i am making. I took my Band of brothers dvd:
    1. ripped it to my Hd with smartripper
    2. used dvd dvd2avi to get my d2v file and convert audio to wav down to a 2ch 384Kbps 44.1KHz.wav
    3. used the d2v file in tmpg as the video source
    4. used the wav file as my audio
    5. Used the general vcd ntsc film outline in tmpg encoder.
    For expert setting source i set the the aspect ratio to 16:9, i leave the field order to field A, and I set video type to interlacing,
    6. then under other setting:advanced, i set the video arrange method to custom since I need to bring the picture to 352X194 to make my aspect correct.

    thats all....my movie quality comes out great, but every 5-10 minutes I get a loud scratch, hiss, pop, noise. I have tried running my wav file (that doesn't clip at all ) in sound forge 6. I've normalized it and researched that well. It only happens once tmpg encodes it. any help

  4. The problem I was having was when I was converting to DVD only, the same clip encoded using the same method but to SVCD did not have any clicks or pops. It was only DVD format and it only seemed to be when converted to mpeg audio. Since one of my DVD players won't read the disc if I use mpeg audio anyway, I have since been converting all DVD audio to ac3 instead using BeSweet.

    Sorry I couldn't provide you with more insight to your problem.

    Good luck!
