Help! No Sound on video after rendering

[schiass Profile Private messageWebsite]

I am trying to finish a huge project that has to be ready tomorrow. It has short video clips from both a mini dv digital camcorder and 8mm analog. They all sound fine in Proshow but after burning to DVD the clips from the analog camera have no sound. I captured, edited, and rendered the video in Pinnacle though my Canopus converter, then dropped the clips into Proshow. I have also tried to just render to a file and the file plays fine, then I tried to burn the file, no sound again.

Anybody have any ideas? I'm freaking out right now!

Thanks!

Hi schiass,
I'm no expert in video matters, but I'm trying to help.
The programs with which you converted are not important. What is important is to what you converted.
So, please tell me exactly to what format of video you converted, and most importantly what type of audio is in your video.
If you don't know, then install the program gspot which will help you identify your video type.
Download and install from here: http://www.headbands.com/gspot/

I opened it with gspot and it says:

Audio

Codec PCM Audio

Info 48000Hz 1536 kb/s tot (2 chnls)

No Codec Required

I render both types as AVI files. Both types of video say exactly the same thing in gspot. But only the video that was originally analog has no sound on the dvd.

As I said, I'm no expert, but PCM is not recommended.

If you are making an NTSC DVD, then try to convert your movies to avi with audio AC3 (Dolby Digital 5.1) and see if
it doesn't solve your problem.
Maybe somebody else can help more.

While I don't have the answer, I do need to make a comment on the
LPCM statement -- *if* you are using NTSC and creating a DVD,
the spec for that actually says that at least 1 audio track must be
either LPCM or AC3. AC3 requires an encoder, so many people
do NOT have access to that and most of the video editors seem to
want to put the audio in Mpeg Layer 2 (compressed). While *most*
of the current crop of DVD players will play NTSC disks with the
audio in Mpeg Layer 2, not all of the older ones will and the result
is usually someone you loan a DVD to (or make one for) comes
back and says "Nice show, but no sound" and yet the same disk
plays in other players just fine. The standard for PAL says that
Mpeg Layer 2 audio is acceptable for one of the audio channels
though. Ain't standards wonderful ?? (I know about this because
I ran into that exact situation "nice show, but no sound" and had
to do some research to figure out what the issue was).

This might be too late but if not, have you tried separating the video and audio in Pinnacle as "video with no audio" and "audio only wav file" and importing each into PSP?

ALL my shows play just fine in my "newer" DVD player (which is about 2.5 yrs. old), music and all.
But no sound when I play on my "older" DVD player.

And you have encoded the audio to Mpeg layer2 right ??
That is the issue I ran into - plays fine in most, but not
all (same physical disk). If you encode with PCM, I bet
it will play in the old one that will not play it now

I finally figured it out, I guess. Well, I got it working. I'm sure sure exactly how. I rendered the video in Pinnacle in AVI and MPEG2 format which put the audio in PCM and MPEG respectively. Neither had sound after burning. My DVD player is very new. I then tried NERO to capture the video in MPEG2 format and it worked.

Thanks for all the responses!

Well, that is kind of an odd path, but if you need to stand on your
left foot to make it work, go for it !! Been there done that !
(although once you get this hot project out, it would be a good idea
to figure out just where things got confused ... )
