One more round of applause for this 3 1/2 year old post by guns1inger...
An Xvid that was out of synch by about a minute led me to this site, as I thought I would give it one more try. I found guns1inger's post after about four minutes of searching these Forums, downloaded the recommended software, and had a properly synched avi in less than fifteen minutes total. It took all of three changes to the timing (+800ms being golden) to put the file spot on. Outrageous! Another half hour of scanning the site made me want to dive in deeper. Thanks for a great site and for the time and effort put in by all. I hope to become knowledgeable to pay it forward.

I currently use a program called "Next DVD ripper" to convert DVD's to avi files. Often times it converts the dvd to avi with no problems, but I have noticed with some movies that there are some a/v sync issues. I've tried using VirtualDubMod to fix this, but I haven't had any luck. Are there any other fixes that I could try? I am also interested to know if there are any better ways(programs used) to convert my dvd's to avi that maybe some of you more advanced users might use. I am not opposed to using a couple of programs, one that gets through the dvd encryption and then one that encodes to avi, if this will give me better results. Thanks again for all the help!

In VirtualDubMod, I add a VBR audio with Direct Stream Copy and by the end of the runtime, the audio in the resulting file has gained a noticable skew. I didn't choose to rewrite the header. Can I do anything, e.g. in Audio/Video Interleave options to fix it, without converting to CBR?
I'm having some audio sync issues with a video I recorded on my Samsung Galaxy S (Android Phone). It's out of sync on the phone, I didn't do any conversion or work on it. I'm not sure what caused it as I've never had this problem before, but my question here isn't how to avoid it on my phone but rather how to fix the recordings I do have. It appears the audio stream is shorter than the video stream. Is there a way I can fix this? or is it a lost cause?

Kewjoe, your query relates to a container other than the one discussed in this thread - AVI, which is usually for video encoded with XviD or DviX. Your container is 3GP and the codec AVC aka H264. But a constant delay can be easily fixed. In your data the audio is shorter than the video.
Determining the delay in MPC: Play the file and use the "-" key (if audio is late) or the "+" key (if audio is early) on the numeric pad. On a laptop, use the Fn key and the corresponding extension key for "-" and "+". The value will show in the status bar of the player.
Changing the delay in mkvmerge: Add the file, select the audio track, go to the second tab and enter the value in the field for the delay. The output can only be an MKV file.
VLC to determine a value of 500 Audio Skew Correction. Original file size is 697mb. VirtualDubMod status window shows a projected file size of 691.55mb and has been working for 2hrs08mins. The destination folder has my output file showing as 712mb already but is unplayable. The bit rate of the original file is 123kbps. For others who have had success with this approach the process seems to have been fairly quick from what I've read. Any Ideas what I might be Doing wrong or if I have to change a step?
xmediarecode and now have a file of 1.07gb at 128kbps. I'm going to try again and see what happens with this one. If it doesn't work I have one more option with virtualdubmod plus your solution with virtualdub. Thanks again.
OK, so that didn't work. When the Green progress bar reaches the end the job clock just keeps progressing. I have a file of 1.09gb but it is not viewable. The main program window has a header saying(dub in progress).
When I "save file" and select "direct stream copy" should all the check boxes be checked, unchecked or some combination thereof?
Turns out I had two copies of VirtualDubMod, one doesn't work properly. Been so long Since i Used the program I forgot about this issue. Sorry for wasting our time, lol!

I read a number of the pages which talked about MPC early on. It mentioned setting a numeric value during playback to help a sync problem.
I saw no mention of another technique from a popular player:
VLC can change audio delay plus or minus in 50 ms increments from the keyboard.
-- > Use the "k" key to advance
-- > Use the "j" key to subtract time.
This is best done at a Pause in the playback. It's fast and efficient and can indicate what needs to be done for a permanent fix.
I have used it on several movies on my system and have no playback problems at all. I have then independently verified the results on standalone players and it works. I suspect your problems lie elsewhere.
adamstillwell - that's also thing I want to know
I am going to throw my problem out before I have tried some of these solutions. I just want to get an idea if I'm on the right track of trying to open my AVI in Mediaplayer or VLC.
I transferred a feature film from VHS to my PC using a Diamond VC500 capture device and the ArcSoft program that came with it. The audio gets out of sync somewhere, I haven't pin pointed it because I just checked it this morning but it seems to be pretty early on. It's delayed and coming after the actors lips star moving and it's a pretty long delay.
I'm wondering how it gets off during the capturing process?
I really am a newbie. I didn't think to shut down TSR programs like my anti virus software and what not. I will tweak when I get home today and try again!

Software called Plural Eyes will sync all your Audio and Video up, you can then export the settings as an XML file and then import them into your editing software such as Premier or Final Cut, good luck

Why is it that exporting WMV (supposed successor of AVI) fixes vid/aud sync issues (rendering or exporting) in most cases when rendering, isn't that a form of AVI?
Winavi to change over the scenes to dvd arrange, all Ok, sound is fine when I check them. I at that point utilize either nero or TMPGEnc to encode the dvd's. it at this phase things turn out badly, having copied two or three dvd's before checking the dvd's, I found that the sound had left match up on the majority of every scene, by about a second or thereabouts, and completely through. When I have checked the yield on nero before consuming the plates, the sound was out at this stage.
Please delete this reply.
Heyo, would this still be the correct thread to ask for general AVI sync issues?
I'm currently trying to digitalise my NTSC-J VHS tapes and I've tried out various Nero Video versions as well as VirtualDub.
However, whenever I try to digitalise them as AVI files, the audio seems to start a little earlier than it should.
I have already tried the various Timing settings, but they only worsen the problem, if anything.
What I have noticed is that this problem doesn't occur when I use Nero's MPEG format.
I don't think VD is capable of using other formats than AVI, is it?
I've also tried various compressions, none of them seem to work. :/
I should probably mention that I'm a super-newbie in this field, my VCR is not the best and neither is the capture card.
This is my current setup (the PC is a spare lol):
Windows 10 64x
AMD Phenom II x4 975
NVIDIA Quadro 2000
Hitachi DA4-Head M70EM
Hmm, okay, thank you. I will try that, but... is there nothing in VD that can automatically do this?
I mean, I suppose that's what those sync settings are there for, but they don't seem to work with AVI files?
But VD only does AVI, right? So shouldn't that be fixed? @.@
I kinda feel stupid now, damn xD
Because I actually am using VD2, but I thought there wouldn't be any changes to that aspect, since I don't know where to pick the file type^^'
So basically whenever I mention VD, I mean VD2. Sorry for not being clear on that ><
Please tell me, where can I change the file type? I can change the encoding to MPEG, I think, but the resulting file is either super-laggy, has no audio or won't play at all...
