Audio sync issue...

[aconnell]

I am having the classic audio sync issue when taking an MPEG (MPEG2 video, audio sampled at 48000Hz 16bit) and adding it to a project in VS8.0 with a menu that contains no audio. The beginning of the video is ok... but it gradually gets out of sync so that when you reach 45m, it's about 3-5s out of sync.

I've tried converting the MPEG as an AVI, but the AVI resulted with sync issues as well. I've made sure all my drives are defragmented and disabled just about every startup application... and I don't use the PC while the build is ongoing. I build to an ISO to check and see if the sync issues are ok, then the plan is to burn that to a DVD. Before burning I disable antivirus. I've also tried disabling the Smart Render.

My Hardware:
P4 2.4 Ghz w/ HyperThreading
Asus P4S533 motherboard with onboard audio (ADI AD1980 6-channel CODEC)
1GB RAM
30GB OS/programs drive, 300GB data drive (w/ 200GB+ free)
ATI Radeon 9800 Pro 128MB (w/ latest drivers)
My Software:
WinXP Pro SP2

Could there be some settings I have not yet checked or something on the video card?

Your video card has nothing to do with video except displaying it unless your using a ATI AIW. Realistically any video card will do.

Have you checked to see if it's in sync before import it? Test it in a few different players too don't just trust one.

Yes, I've tried it in 3 different players on one PC, and in two players (WMP10 and WinDVD) on my work laptop. Yes the source video is in sync.

I tried the MPEG2 -> <disable smart render> save as video file (mpg) -> import results into the DVD project and it helped quite a bit... but by the end of a 45 min movie, it was about 1-1.5 seconds out of sync.

Thanks for the reply... any other ideas?

The OOS problem has existed far too long!!! Everything I have made in the last 2-3 months has shown an Audio/Video synchronization problem.

It is affecting everyone. Ulead has not taken this problem seriously. They must be made aware that the entire user community is frustrated and fed up with their lack of response.

Everyone on this forum must file complaints with Ulead Tech Support AND with Ulead Customer Support!

I agree with you jchunter. I had no OOS problems when I was using Video Studio 7SE and Movie Factory 2SE. I recently upgraded to Video Studio to ver 8 and Movie Factory to ver 3 and now every dvd I try to make has OOS problems.

I'm wondering whether the problem was caused by one of the updates I downloaded and installed. I may clean out my system and re-install Video Studio and Movie Factory without any updates and run a few tests and see if the OOS problem goes away.

Just curious and not that it should make a difference but does the audio go out of sync if you use AVI? as a source from start to finish.

Merlin, over the past two weeks I've completely cleaned my system, re-formatted the hard drive, re-installed Windows XP and installed only the minimum software I need to reduce the chances some other program might interfere with DVD burning. Other than reading email, lurking on newsgroups and surfing the Internet, there is little more I wish to do on this computer than create useful (not necessarily perfect, but useful and watchable) DVDs of selected analog cable TV recordings. These I either capture directly to my hard drive through an ATI AIW 9600XT or capture from previously recorded VHS. Ulead VideoStudio has been my editing/authoring software of choice from the time I installed version 6 which came with my Sony DRU510A burner. I've subsequently upgraded to UVS7 and later to UVS8.

Since Wednesday of last week I've done little else than attempt to create one, single DVD that didn't have the audio/video sync problems expressed by so many others on this forum. Researching and reading everything I can find, I have practically lived on this forum as well as http://www.videohelp.com and Lordsmurf's http://www.digitalfaq.com/ and have tried virtually every suggestion offered here -- thus far without success. Every video I've attempted to process is perfect -- until it is processed in the Share mode. (Yes, I make sure there is nothing in the Time Line when I begin this process.)

I thought I might devote today towards editing my 2-hour clip (which, BTW, consists of removing commercials only) in VideoReDo and then trying to author in USV8 with SmartRendering turned OFF. (When I tried this earlier in the week with a VideoReDo edit but with the SmartRender process ACTIVE during the share mode, I feared the potentially 4-hour rendering process and the indicative stresses it seemed to be placing on my system might damage to the processor (P4-2.8C) or the power supply (475W). I aborted when the temps reached and stayed at 48 C for some 20 minutes.)

I simply want to see if UVS8 will take a clip rendered by VideoReDo, allow me to add chapter points and a menu in UVS8 and then prepare Video_TS files that ARE IN SYNC. Honestly, I am not very optimistic.

Having devoted huge amounts of time in the attempt to resolve issues that now seem more likely a product of UVS8, I am swiftly moving to the conclusion suggested above by jchunter. Perhaps there will come a time when you, too, will consider the same.

I'm not sure if this helps, but I own both Ulead VideoStudio8 and Roxio's Easy Media Creator v7. Both applications have problems with the audio sync... leading me to believe there must be an issue with some setting or with native MPEG2 files. The sync issue is MUCH worse on both programs when using MPEGs vs. when I use AVI's.

Unfortunately, the process of creating an AVI from an MPEG is problematic as well with sync issues resulting in the AVIs.

I seriously doubt it's an issue with my hardware and more with some setting:
P4 2.4Ghz
1GB RAM
30GB OS/Programs, 300GB for data
ATI Radeon 9800 Pro 128MB

Both applications have no problems capturing video... it's just the build of something using MPEG as the source.

What's frustrating about this process is no one seems to post any success stories or how they've gotten around their issues... only people post who have issues but don't follow up success stories... that is assuming there are success stories.

Unfortunately, the process of creating an AVI from an MPEG is problematic as well with sync issues resulting in the AVIs.

Have you tried it by capturing AVI and using it as your source, no rendering etc. to right before you burn, I know you should be able edit mpeg, but VS8 isn't the only video editing app that has issues with MPEG nor is Roxio.

MPEG was never meant to be an editable video, AVI's such as DV or one using the huffy codec on the other hand were made for it. http://www.digitalfaq.com/capture/avivsmpeg.htm

I'll tell you how my work flow goes, I'm taking for granted I already have a AVI in sync on file. I'm using MSP but you can apply it to your apps. I set my project settings to exactly match my AVI, the reason for this is I like to preview a lot so the only encoding that has to be done is where I've edited. Once my edits are done I export as MPEG using whatever my final output is. that's it there's nothing left to be done to the video. It has gone through as little processing as it can. I import into DVDWS and create my disc, I use the "do not convert" feature and create a disc.

Doing it this way I have never had any sync issue....none. Another thing I would like to point out is that you didn't see too many people on hear having sync issues using AVI.

[aconnell]

What about the cases where you have an MPEG2 and you can't get it to an AVI? What you described about using AVI as the source is just about what I am trying to get to.. and don't have too many problems doing such... it's just getting them to the AVI that's causing a problem.

[thecoalman]

You capture in AVI, if your using a a harware encoder card then you out of luck. What are you using to capture?

edit: you could try converting your mpeg's to AVI...if need be but you want to process the video as little as possible.

[frankhad]

Just curious and not that it should make a difference but does the audio go out of sync if you use AVI? as a source from start to finish.

I've been reading your earlier postings (here and on videohelp.com) with considerable interest; and given much thought to your suggestion that videos are best captured in AVI. Lordsmurf, as you already know, suggests that analog captures requiring only the removal of clip segments (such as removing commercials) need not be construed as true "editing" and therefore ought to remain unchanged since nothing within the remaining clip will have changed. I'm still not sure this is totally accurate since I can understand that the ending, and leading frames between that portion of a clip that has been removed can conceivably be altered in some way. For the moment I'm content to leave this for you and he (and those far more experienced than I) to resolve.

Nor have I attempted to record or capture anything in AVI since I currently have several 30-min to 2-hr (MPEG) programs stored on one of three hard drives. I perfer to deal with these before experimenting with the AVI vs MPEG issue.

This brings me to your comment above.

My recordings are simple (analog) cable TV programs in which I wish only to remove commercial ad segments, create chapter points and a menu before burning to DVD. Please trust that I have been meticulous regarding the setting of all properties and ensuring these properties match all the way through the capture/edit/author process.

Most of my captured MPEGs have commercial ads all throughout the clip which I remove during the editing process. However, because I've been having the same audio/video sync problems as so many others, I've been experimenting with a 2-hour commercial-free movie (captured from TCM) that requires nothing to be removed from within the movie itself. I'm simply deleting an unneeded portion from the beginning and from the end.

The most important point to be made here is that everything I do in this entire process plays back perfectly UNTIL the final product is produced in the Share mode. So my question to you is this: If audio/video problems are inherent in a clip that has been captured in MPEG and NOT in AVI, wouldn't they show themselves in earlier renderings and BEFORE the attempt at the final process?

When I bring a clip into the Edit mode of UVS8 and delete the unneeded beginning and ending portion, the remaining clip is saved and becomes another seperate clip altogether. I have never had an audio sync problem at this stage. It is only at the final stage when I process in the Share mode and save this rendering to disk that the clip is OOS. (And YES, I make sure this clip is NOT in the Time Line when I begin the Share Mode.)

What do you think?

What do you think?

I think there's a bug in the program.... Especially considering the fact that this has suddenly appeared, apparently this wasn't an issue before? That's just specualtion on my part though.

The point is why bash your head against the wall . Try a different route. If it's happening to so many then why fight it?

Complain if that's the case


I like that last emoticon...hehe

[aconnell]

I can capture to AVI just fine... I have some MPEG2 files that I need to put on a DVD. I didn't capture these... they are captured by another device which I do not have access or the abilityto change it and tell it to capture to AVI instead... it can only capture ot MPEG2.

[thecoalman]

I can capture to AVI just fine... .

Well give it shot, I'm curious to find out what happens and I don't even own the program. Just make sure you use the same setting right up until last stage?

What device are using to capture AVI?
