Audio out of sync gradualy

[Sergula]

Hi!
First, i'm sorry for my bad English, I'm french.

I have a big problem and I need help!
In VIDEO CONVERTER to AVI, the video and the audio, at the beginning of the movies I convert is ok... but the more I go near the end, the more the audio is
out of sync! (audio late over 5 sec )

Profile: generic. avi. divx. mp3
Got same when converting to WMV.
Got same when converting with XVID, DIVX, 1 or 2 pass,

Thanks for the help... I need it!
Serenna.


P:S. version of my dvdfab is 8.0.2.2

Go to Common settings of DVDFab and then change the A/V codec to software. not sure what video card you use but if it ati this might help changing to software

[Sergula]

The videocard is a ATI Radeon X1250

All the settings are at SOFTWARE... all the others are NOT supported by my videocard

I uninstalled the k-lite codec to put all the new one... NOTHING
plz, find something ?

Have you checked that the source FPS is the same as the converted FPS - you can use something like Gspot to do this (or load it back into FAB?) - if the audio moves gradually out of sync this can be the case - it happens when I Rip Blu ray to MP4 because FAB does not produce an MP4 output other than 23.976 FPS even though the option is same as source. As a result my 25 fps source is turned into a 23.976 output with major av sync problems.

I'm new to DVDFab.
Where do I find "Common settings"

Try the little green tick mark at the top right of the Fab pane.

ok, I've check with YAAI, and there it is :
ORIGINAL IS : framerate 23.9751 fps
microsecond per frame 41710 ms
frames 129572

and the copy is :

framerate 23.9760 fps
microsecond per frame 41708 ms
frames 129316

This would seem to be the cause or your problem but the source FPS seems a bit puzzling. Are you using the 'same as source' FPS option on the converter (and what is your source - ripped DVD, Blu-ray?) (I dont use the converter myself just the Blu ray Ripper). What bit rate options do you use on the converter?

[Sergula]

I did try the ''same as source'' , here it is :


original: copie:

running time : 5404.45s running time 5392.08
framerate 23.9751 fps framerate 23.9750
microseconds per frame 41710ms microseconds per frame 41710
frames 129572 frames 129275
sample rate 44100Hz sample rate 48000Hz
bit depth 16 bits bit depth o bits ( ??? )
color depth 24 bits color depth 8 bits


it's an AVI file that I wish to crop, but got that problem with ALL files now!

missing second part...

the copie is :


copie:

running time 5392.08
framerate 23.9750
microseconds per frame 41710
frames 129275
sample rate 48000Hz
bit depth o bits ( ??? )
color depth 8 bits

You English is better than my French but I'm a little confused - in the second example you give, the 12 second difference in running time cannot be explained by the .0001 FPS difference. Do you still get the gradual shift in AV sync with this or is there a sudden switch of sync?
Also is your source a ripped DVD?
Do you get the sync problem with all sources?
Does the coverter allow you to specify a fixed or variable bit rate?

Thanks for the English part!

Yes I still got the sync problem
Is it sudden ? gosh, I did not think about that! I will look at it tonight!
the source, it's downloaded movies and yes, it's with all sources now.
the converter allow me to specify a fixed or variable bit rate,
but it did not help.

p:s. on my old cpu, I did not have those problem ( single core )
But with this cpu ( e1203a dual core ) with win xp 32 bit, I did got the sync problems, so I remove DVDFAB and installed it again, still out of sync.
After I did a clean install of WINDOWS 7 ULTIMATE 64 bit ( the real one ) and same thing. I reinstalled the codecs (k-lite) and same shit!

I need help, BAD.

We do not discuss the copying of downloaded movie on this forum.

As stated by the administer any thread mentioning downloaded movies will be closed . No exception.
