"Popping" Sound In DVD Audio Track

[D.V. Dee]

I recently burned a DVD video with Video Studio Pro X5, and encountered a very brief, but audible "popping" sound in the audio track (the video plays just fine)...

The video footage was originally shot in FlipVideo MPEG-4 and converted with TEnCoder, so I could import it OK into VS Pro X5...here are the output parameters for that footage converted by TEncoder:

Video:
Codec Xvid
Bitrate 2000
Common Sizes 640:480
FPS 30
Aspect Ratio 4/3
Audio:
Codec MP3
Bitrate 128 Kbps
Channels 2
Srate 44100

Container AVI
Encoder Mencoder


VS Pro X5 DVD Burning Output:
NTSC drop frame 29.97 fps
MPEG 24 bits / 720 x 480
Upper Field first
[DVD-NTSC] 16:9
Video Data rate Variable [Max 8000 Kbps]
LPCM Audio 40000 Hz Stereo

Does this data give any clue as to the "popping" sound in the audio track?

Was there "popping" from the tencoder export before importing ? or at the timeline preview stage ?

Did you export an ISO or did you burn directly from Video Studio Pro ?

Did you apply any audio effects ?, normalization , that sort of thing ?



As an aside I wouldn't use MP3 as an intermediate for import, I would have used uncompressed audio (since that's what you're using for the DVD anyway) . 128Kbps MP3 is just losing quality for no good reason . At least use a higher bitrate (but even better use uncompressed audio) . Same goes with xvid for video

There was no "popping" on the TEncoder export before importing...and no "popping" at the Timeline preview stage...

I burned directly from VS Pro...No audio effects or Normalization...

What higher bitrate would be better? (I'll try uncompressed audio, too)

Thanks!

Better for quality, but probably won't help the "popping" you're hearing



If you export another file format from the timeline, like xvid/mp3 can you hear "popping" as well ?

Does the program allow you to export a DVD ISO or authored video files? That way you can test with something like VLC or other software to narrow down the problem

Haven't exported another file format from the Timeline yet, will give it a try...

Yes, VS Pro X5 lets you export a DVD ISO....
