Audio out of sync

[TheEntertainmentKing]

Hi

Just signed up to the forum though have visited for YEARS....
I am having a problem (sometimes) when burning a DVD using Nero.
The file plays fine on the PC but once it is burned to disc, the audio is out of sync, and we are talking a LOT out of sync too.
Any ideas what the problem could be and how I could work round it.
Most movies turn out OK but a few movies are well out.

Thanks

I would try another dvd converter first and see if it helps, like dvd flick(free) or convertxtodvd.

Might those movies have MP3 VBR audio? You can check that in Gspot 2.70. VBR can cause sync problems when converted to MPEG.

And welcome to our forums.

Thanks Baldrick & Redwudz.
Will use Gspot first to see if this is the problem and then try doing it with the Freebie prog.

Checked this, and no, its CBR..... any other suggestions apprecaited..

ALSO

Reauthored using DVD Flick, it was worse, in so much as the audio ran VERY fast, sounded like it was running double speed or faster. At least gave me a laugh.

what kind of file is it?

You may want to check the running times of both the video and audio, separately.

been visiting for years ?

then you already know converting & burning are different fuctions, and that NERO is NOT a great converting program

that most people here convert with other programs then burn with imgbrn

Years indeed, I sense doubt in the reply....

Apologies for my wrong use of terminology, obviously not as literate as your wise self. I DO however admit to not knowing that Nero is not great at converting as it is not something I do a lot of.

Hence the reason I asked for help and advise of people who know more about this here, which indeed all have helped out with.
Having read your reply I guess your piece of advice is.... Nero is not great at converting.
Thanks for your input and assistance.

Hi Pinstipes, its a AVI, thing that gets me is that it plays fine on the PC as a regular file

[Midzuki]

I'm afraid we are not being given sufficient information.
To say "it is an AVI file" is not very helpful. Questions:
DivX? XviD? None of the above? Codec version?
Audio is stereo, mono, multi-channel? 8-bit, 16-bit, or
even better? And the sampling frequency?

Sorry if I am sounding like Dr. Gregory House, but...

try convertxdvd or dvdflick or favc and the burn with imgburn

use gspot and mediainfo on the your source file, to get the specs, FPS, codec , bitrate, audio stream etc

our advice can then be more specific, vbr audio, or RMVB files cause problems in nero and other programs

you may need to demux ( seperate ) the video and audio streams, convert each one and then author the DVD with gfd then burn

I am a novice when it comes to DVD burning, but i have some success with them. It's been my experience that defragging the HDD's that you use always makes a big difference in any huge overtaking like making a DVD.

TheEntertainmentKing - can you post a JPG of what GSpot says when you open your file? Something really weird is going on here if 2 different programs botch the sound horribly during conversion. I'm wondering if your source has a weird frame rate.

[Nelson37]

The statements you have made imply that AFTER converting the original file to a DVD structure, Playing the "file" has good synch. WHICH FILE????? The original, or the converted file on the HD before burning? Essential to answer this question as this points to two completely different issues.

More than likely your original is a Divx or Xvid AVI file, with a non-standard framerate, which can be played correctly on the PC but will have problems converting.

Load AVI in Vdub. Save the WAV. Frameserve to an encoder. Encode the WAV. Author to HD. Test for synch by playing the converted file. Standard methods for handling such files.

No need to shout Nelson. The file I was referring to is the orginal file on the hardrive which is an AVI.
When it is converted and burned to disc, the disc plays out of sync.

Thanks for the info about non-standard frame rate, this even makes sence to myself, knowing little about these issues.

Thanks

Hi and thanks for posting, I am thinking it is the frame rate (with what others have said)
I have posted link to a grab of what GSpot comes up with

Thanks for that Wizard, regarding seperating etc. probably beyond what I know at present.
1st time for everything though I guess.

Thank you for posting a link to the screen capture. It was very helpful.

The good news - your video frame rate is 25 fps. This is fine. We can debate about whether or not AVI can technically be referred to as PAL video or not, but basically what you should do is convert this to PAL format DVD.

Your audio is AC3. This is VERY important to know. You don't need to convert the audio at all. All I can figure is that the fact that it is 2 channel AC3 (perfectly valid, by the way) MAY be causing problems for a stupid encoder that thinks that AC3 must be 5.1 format (5 channels plus 1 subwoofer channel).

My suggestion would be to convert to PAL format DVD and see if you have an option to NOT convert the audio. There is nothing weird at all in the source AVI file, so it should convert OK. I'd try another conversion program if it was me.

[TheEntertainmentKing]

Thanks for the info.
Any suggestion on what program I can do this with?

Much Appreciated

[jman98]

Baldrick's suggestions are good ones.

[TheEntertainmentKing]

Thanks, will go with that.
