Audio and video are unsynchonized
When making a movie, the audio/video are unsynchronized at times. When I exported the first time (file imported from disk) after making a movie, the video froze but the audio kept playing. The second time, when I moved the VTS file off the DVD directly, the synchronizing problem occurred. And strangely, when I exported that movie as an MPEG-4, there was no video at all and WMP played it as an audio file.

Hi Andrew-
There have numerous threads on audio/video sync problems with various versions of Nero but this doesn't seem to fit the mold.
Is this a commercial disc which might be copy protected?
Can you post the vts.... file at a website such as pogoplug so that we can download and test it. -
-
No. It's a burned DVD. It's scratched a bit and a section of the video was bad. I used the file I imported off the disk the first time and edited out the bad section, and it fixed the problem...that one time, and not the audio-only exported file. I later started a third test project and the sound was still off even after I trimmed the vid back to before the bad section.

You can try recoding the file to mpeg-4 in Recode, in case there's some dropped frames.
You could also post it, as I suggested before. -

I tried to edit another video I downloaded from You Tube and when I exported it there was just a black screen and no sound.
When I downloaded Nero 12 from the purchase email, I didn't download the content pack. Could that be the problem?
How do I send the videos to Nero to look at? -

Register with NeroBackItUp and get 5 GB for free.
http://my.nerobackitup.com/register
Then upload your files there and share the link. -

The Content pack should have no effect on what you're seeing.
I don't know which installer was linked in your e-mail. Go to nero.com, downloads, previous product downloads, Nero 12 versions. Download the appropriate installer. Uninstall your version and install the download. After installation, run the check for updates. Then download and install the Content pack.
Then check to see if the problems still occur.
The suggestion by Nero for providing the file doesn't apply because you don't have Nero Backitup 2014 or 2015. Nero MediaHome has Backitup features but I'm not sure you can create an account for it since you have v12. You could try it.
You can use any other free upload service. For instance, I use filedropper.com. After uploading, it will provide a link which you can post here. Note that filedropper has a section which involves internet backup and has a fee. Don't use that page. You could also use dropbox or others. -

Andrew,
The 5 GB of free space offered by Nero is independent of your BackItUp installation. The account can be accessed via your browser - no need to have Nero BackItUp. -
-
I had to buy a new PC (again), so I had to redownload Nero 12. The exported video problem occurred again. How do I send the vid to Nero for analysis as suggested by Wither?

You should send an e-mail to techsupport@nero.com. However, they will need your file so you would need to post it at a website that they can access. As described above, you could upload it to pogoplug via creating an account in nerobacktiup.com. After uploading, you can add the link to your e-mail.
If you do that, please provide a link to the file here so us volunteers can look at it as well. -
-
When I try to start a backitup.com account via my Nero installation, I get a message that an internet connection cannot be established. Same thing when I go to the site directly.

I assume you uploaded the file. You can get a link to it by selecting one of the icons at the top. Pogoplug is acting funky for me today so I can't tell you which one. You can then use the link in your e-mail.

Is that the stream file off of the disc or is it processed in some way?
The video doesn't play, as you mentioned but I just need to be clear what it is. Tech support will need the original stream file or the vts.....vob that you're working with.
Is this video similar to this- https://www.youtube.com/watch?v=Z_kTa... -

I don't think there was image stabilization, but I did timelapse it myself with Nero. It was downloaded from YT.
-
Andrew L,
Please post a link to the YouTube video. -
-
-
-
-
Okay. Where did the comment about image stabilization and time lapse come from? Maybe I missed something earlier in the thread.
Also, your original post dealt with files on a DVD so how did we get to YouTube?
I just want an original file that your using and hasn't been processed by Nero so that we're all working on the same page when testing in regards to no video. Of course, that doesn't do anything for the sync problem. -
-
Sorry. I got sidetracked because I discovered that downloaded videos were blank when rendered with Nero special effects added. They still are, but to get back on topic, here are my own videos. The bad (0001) video has no video (as I mentioned in the first post) but when I imported it back into Nero and re-rendered it as an MPEG 4, (test) the video works and the audio is synchronized again, although the picture quality is bad. Here they are for analysis so you can find the original problem:
PS: I can't get the "get link" option on pogoplug anymore...

Andrew,
You are selecting multiple files. Try doing one at a time. -

Strange. Both videos play fine for me in WMP, NMH, Nero Video, etc. The one that you recoded seems to have been edited.
-
-
Here's a sample .VOB taken directly off the disk. I can't play it in WMP either, but it opens in Nero. Also, when I play the DVD itself, the picture is better than after editing with Nero.

Did another test with an .mpeg 2 setting and again there's no picture.
It works as an MP4, but the picture quality is bad, even with a 2-pass export setting.
Will send files if needed. -
-
Okay Andrew- I played it in NMH, VLC Player and WLMM. It won't play in WMP 11 but that may because I don't think WMP 11 supports AC3 audio.
I went through it piecemeal to find where people are talking so I could see if there's a lip sync issue. Honestly, I don't see it. The best example is where the two guys are sitting at the picnic table eating and one of them asked you if you were calling him old. Didn't see a sync issue there.
Do you have 2014 Platinum? -
-
The sync problem is gone too. When it happened, the audio was MINUTES out of sync and started hallway through. But the quality and file type (mpeg 2) playback issues are still there. Did you notice the better quality with the raw VTS/VOB file?
I'm using Nero 12. -
-
What do you mean "The sync problem is gone too."? I don't know what you did.
I used the last file you posted at pogoplug. -
-
-
-
I really wanted to know what you did to get rid of the sync problem. A couple of days ago, you were messing with mpeg-2 and mp4 and had problems. Did it just disappear on it's own?

Isn't that special! Technology is great- when it works.
Thanks for the reply. -
