No sound after burning

[janlafata]

Hello,

I am running Vista Basic x64 on an above average powered machine and am using Ulead
DVD MovieFactory 6 Plus to edit and burn. I had this happen once before, so I think I know what the problem is...After I burned this movie file to a DVD+R, I played it back on my home DVD player and there was no sound.

Like I said, this happened once before and it was because I had adjusted the bitrate too low in order to fit it on the DVD. But this is the first time I had to load 2 files for one complete movie and I was just wondering if that also might have had anything to do with it.

After I had loaded it, I noticed on the Ulead that a reference to "joining video" was greyed out, so I'm assuming it did that automatically.

Thanks

Just make sure you used AC3 or LPCM as sound.
Maybe Ulead encoded sound to mp2. Standalone won´t accept that, NTSC.
Check with Gspot the Vob files.

After you load your video file into Ulead, do you see the audio on the timeline? Do you hear audio when you preview it in the editor? What file format are you importing? Ulead may not support the format.

NoBuddy, SCDVD,

Thanks for your replies! NoBuddy...In the past I have always had Dolby set as my sound option, however if you feel that I would be better off AC3 or LPCM, I will try that option. What are the advantages though of going with AC3, and wouldn't you need to have the AC3 Codec installed? Also...What is LPCM?

SCDVD...To answer your question, I haven't seen that option come up yet in the the Ulead DVD MovieFactory but I think it comes up if you want to edit in the subtitles. I am inmporting an avi file and usually I always have to lower the bitrate to get Ulead to it to fit on a 4.7 GB DVD. The Ulead does not do it by default.

Dolby AC3 or LPCM (Linear PCM) are both highly compatible for DVD use. LPCM is similar to CD audio, but uses a lot of space compared to AC3. Most times with DVDs, AC3 is 5.1 surround sound audio, but two channel stereo can also be used.

But check your file with Gspot and see if there is any audio, and what format it is.

Same thing 8)

What is LPCM?

What redwudz stated, it is UNcompressed audio.
DD/AC3 is compressed audio but using LPCM takes up way more space which in turn reduces space available for video content which in turn reduces the quality of said video.

DD can be 1.0, 2.0, 2.1, 4.0, 5.1 and maybe some other variations.
2.0 and 5.1 are the most common on retail dvd's.

DD/AC3 & LPCM are in the NTSC dvd specs, mpg or mp2 audio is NOT and is not required to be playable by standalone NTSC players.

Where mpg or mp2 audio is in the PAL dvd specs.

Just a side note on this. The DVD spec for PAL DVDs, doesn't include AC3. Many but not all PAL players will play AC3 however. Nice mess, huh!
