Out of Sync Sound with 2 hr Project Rendered to DVD

Post by BandOnthe »

I just spent a pile of money on Studio Pro 8.0, but then when I tried to make a ~2hr video tape into a DVD, I found the audio was 1-3 seconds off by the end of the movie. I spent days trying to find the fix to this on the internet. After making sure I was capturing the avi as a 48kh DV-1 file, ..., trying Studio 8 (e.g. DVD Factory), DVD workshop (I have version 1 without Dolby), ... I was extremely frustrated. The avi file played fine with no sound sync problems, but the DVD file was always out of sync. Finally, I found a bunch of internet articles blaming problems like this on DVD Factory on ULead. Sure enough, when I used Sonic MyDVD with the avi file, the sound was fine on the DVD. (The picture was a bit pixilated and no Dolby, of course.)

I'm really ticked off at ULead. Going to the DVD Factory forum, I think they're (you're) in a state of denial. I can assure you, if you don't get this fixed my next purchase will be Adobe and I'll never come back to ULead. I'll also be happy to share my experience with all comers.

I suggest a patch, quick!

(This post is essentially repeated on the DVD Factory forum.)

How did you get the AVI file into your computer?
ieee1394 cable
USB 1/2
TV Card etc.

Please could you go to your profile page and complete your system specification details.
Thank you

My guess is definitely a software conversion problem. I have the exact same problem / behavior with the copy of Ulead Videostudio 9 I just purchased. The .AVI is captured fine but conversion to MPEG for DVD is always out of sync at the end of a long (> 30 min) video no matter how many settings or recommended procedures I've tried. It is definitely time related, like a small error that builds over time. I can take the same piece of video that has the audio out of sync at the end of a long piece and if I only convert a short segment of the end that short segment is fine.

Sorry I can't be of help. I haven't heard back from Ulead yet. You're not alone and my solution will be the same as yours if they can't get this resolved quickly -- "goodbye Ulead, hello Adobe and tell everyone I know".

Sorry but I must pose the same question to you as that posed to BandonThe
Neither of you have supplied any information regarding your capture methods. OK many people have posted out of synch queries. In most cases the problem has ben traced back to incorrect capture methods.

Incidentally the only time I ever suffered out of synch issues was in my early days when tried working with MPEG files. I made a lot of research about the subject to discover what an MPEG file is - it is the JPG equivalant of a BMP in the still image world and not designed to be edited other than with a specialist MPG editor such as Womble or Video Redo.

This Web Forum is not supposed to be a moaning ground, it is a place where we users can exchange ideas and share our past experiences and hopefully assist each other. If one of us has a problem the chances are that another user HAD that problem and is able to tell us what they did to resolve it.

This is not restricted to Ulead products, go and have a look at the user boards of the competitors products and you will find the same issues arise in their postings.

Sorry, the details are posted in the VS9 forum..... Just seems like more than coincidence that another user of a different ULEAD product is experiencing the same problem. Makes it seem like the probability is greater that there is some common problem in the .AVI to MPEG conversion process.

Sorry for the complaining at the end but I can empathize with his frustration as I've spent a lot of hours trying to identify the cause and get the same problem resolved. Hours I'd hoped to spend getting my videos onto DVDs.....

I used to have this problem fairly regularly in MSP7, but haven't run into it yet with MSP8. In my editing I'm often forced to use a mixture of DV and MPG sources (not the best method, but I often work with a mixture of digital and analog cameras).

One way I found to get around it when creating the MPG output for DVD is to load the project file and go onto the timeline in MediaStudio - and using the scissors, cut the video every minute or two. You might want to do this using a copy of the project file (so you don't mess up your original). Once you've done this, render the MPG video file as usual.

This seems to make MSP treat these as a bunch of short videos (seamlessly streamed together on output) and prevents the final video output from drifting and getting out of sync.

There are a series of threads on this web board that discuss some of the reasons why your audio might get out of sync - you might want to look back through these a bit. It's been suggested that this might be caused by the odd dropped video frame in the original capture (without a corresponding drop in the audio), which will cause it to drift a bit.

I hope this helps...

Another frequent cause is using MP3 audio for, e.g., background music. This goes away if you convert to wav before putting it on the timeline.

My longest DVD project was >3 hours (from DV) and it is perfectly synched throughout, and many others have succeeded in doing the same, so it may be concluded that there is nothing inherently wrong with the software; whether your problem is due to hardware, input files, incompatibility with other software (Roxio and Nero are devils in this respect) or whatever, I have no means of telling.

The Problem
By the end of a DVD, there is a ~2 second offset between movement of peoples mouths and the words themselves when viewing the DVD via WinDVD. This happened with MovieFactory (and also DVD Workshop on the same machine), but not with MyDVD on the same machine.

Properties of your source files (format, file size, where did you get it?)
I produced my avi file (Microsoft AVI, 29.970 fps, DV Video Encoder - type 1, 720x480, 4.3, DV Audio - NTSC, 48,000 kHz, Stereo) by playing a 2 hour VHS tape through my Sony PC115 DV Recorder, connected to my Laptop (see below) via FireWire. I've since deleted the file, but recall it was 20 to 25 gigs in size. I captured it using the Capture feature of Studio Pro. It was 1hr 59m in length with no significant dropped frames. More importantly, when I played the avi directly through InterVideo WinDVD, there was no loss of audio sync at the end of the file.

What devices are involved and their mode of connection?
See above.

Project Settings
The avi file was not modified within Studio Pro, but in Studio Pro I envoked the MovieFactory DVD authoring utility, pointed it to the avi and then set it loose.

Output format (file, DVD, VCD, SVCD)
DVD

PAL or NTSC
NTSC

Error Codes (if any)
There were no error codes.

System information (please fill this up in your User Profile).
HP Pavilion zd8000 with a 3.4GHz processor, 2G of ram and a 100G hard drive, although the avi was on a USB 2.0 160G HD. I run XP SP 2.

What were your settings for encoding within MF4? Bitrates, audio format etc.?

A total of 8256 kbit/s is too high for many DVD players to handle, especially for DL which you must be using to pack it in to one DVD.

I suggest you do a try at 6000 kbit/s CBR with the audio at 192 kbit/s and 90% quality. You probably won't notice the quality difference (this is determined largely by the DV format) and there is a better chance the audio won't trip up.

OK, I'd given up in disgust but started over (rerecording the avi) as suggested: same effect. By the end of the film, the sound was running a second or more ahead of the picture. Very obvious and irritating. Note this happened when I viewed the ~6 GB DVD folder directly from my hard drive, using WinDVD. Sound on the avi file itself is synchronized, as viewed with WinDVD from the hard drive.

Properties of st4_0001.avi created 11/28/05:
Microsoft AVI files - Open DML
25,147,589 KB
29.970 fps
7140.674 s
628.04 kbps
DV Video Encoder - type 1
24 bits, 720 x 480, 4:3
214,006 frams
DV Audio - NTSC
48,000 kHz, 16 Bit, Stereo
342,752,352 samples
Sound and image in sync when viewed with WinDVD directly from my hard drive.

MovieFactory DVD Setup (envoked through Video Editor 8.0):
NTSC DVD
90 Quality
Constant 6000 kbps
Dolby Digital audio
192 kbps
6.08 GB DVD file produced in about 2 hrs. Audio a second or so ahead of image when viewed from disk on WinDVD.

Note it's my usual approach to produce a DVD Folder of arbitrary size, then shrink it to fit a standard DVD using DVDShrink. However, the sync problem appeared before this step, on the file produced directly by ULead MovieFactory.

My equipment is described in a previous post but more than meets the nominal requirements for MS Pro. The avi and DVD Folder are on 160 GB USB 2 hard drives. MovieFactory should have had no time problem, since it was using an available avi file, not capturing a live signal.

As before, just to show what I expect, I again used MyDVD to make a DVD folder from the avi and, as before, the sound was perfectly synchronized when I viewed the oversized DVD folder on my hard drive.

I hope someone can help or that ULead will provide a fix.

Do you have the possibility of transferring the avi to an IDE hard drive then encoding to an IDE hard drive. I'm not saying this is the cause, but others have reported similar problems when using USB HDDs, especially when more than one item is plugged into USB ports (keyboard, mouse, memory stick, converters, multiple drives etc.). The problem may be due to queuing in the bus. Worth the try, anyway.
