Help Please - Audio out of Sync with TMPGEnc

[klm1702]

I have a problem when converting to Mpeg in TMPGEnc, the audio goes way out of Sync.

I've read the guides and tried everything suggested but it still won't work. Each time I preview in Windows Media Player everything looks fine yet as soon as I copy onto disk and try watching with my DVD player the audio is way off.

I think the problem is when I convert with TMPG but I could be wrong. I just don't understand what the problem could be so any help would be appreciated.

The most frustrating thing is this is one of the best video quality movies I've had yet! If only I could get the audio to slow done a bit!!!

Thanks in advance for any advice.

[eric5417]

have you tried compressing the audio. that worked for me.

[klm1702]

I don't think I've tried that, how did you do it?

Thank you

[eric5417]

first you split the movie into video only and audio only with the de-multiplex in tmpegenc. then you play the video only file with real player or whatever and write down the total time of the video. then open up the audio only in a sound editing program like sound forge, cool edit or what i use, audio cleaning lab. then in the program go to edit (could be different for some programs) and select resampling/timestretching. now click on the option for timestretching and there should be two text boxes--one with the old time of the audio track and one with the new time. change the new time to match the length of the video only file. then press okay, let it resample, export as wav. then bring the files back into tmpegenc and put the video back together.

Thanks for your help with this. I will give it a try, fingers crossed!!!

Is there any good freeware sound editing programs? If not, does anyone know which is the easiest to use?

Thank you

[secretagent]

well goldwave at goldwave.com is shareware. it will do what the others will but that is not the way to fix your audio synch problem.
get virtual dub (free) from this site in the tools section
then open your file go to audio on the file menu check full processing mode, then go to audio again and check conversion, then check 44100. 16bit, hi quality, stereo. then go to file menu and choose save as wav. then open video in tmpgenc and use your new wav as the audio source and viola your problem is fixed.

[klm1702]

I tried to do what you suggested in VirtualDub but when I go to file/sav wav I get an error message saying:-

ACM failed to suggest audio decompression format

Do you have any ideas what the problem is?

I really appreciate everyone's help with this.

Thank you

Is it a Divx or an Xvid avi filethat you are encoding?

[secretagent]

you must give more information about your file. in vdub from the file menu check file information and it will tell you about the video and audio types
also you can downlooad gspot from the tools section and it will tell you what codec is used and whether you have it installed or not.. if your audip info says unknown tag 00xxx or some number you may be dealing with xvid, windows audio, ac3 of osomething like that

I have a problem when converting to Mpeg in TMPGEnc, the audio goes way out of Sync.

I had this when capturing with Virtualdub. I learnt it was because I had ticked the 'lock video to audio' tab, once I unticked it everything was fine.
Just while I'm typing....
....Be careful using the mpeg tools function in TMPGEnc - this will result in out of sync issues if you join too many.
I joined twelve fifteen min mpegs and the the 12th was out by a second - most frustrating.
I corrected it by joining two at a time and created six mpegs - no problems whatsoever
Also, it was suggested to me *never* use WMP to view avi's or mpeg's - I found if I played an mpeg in WMP the sound was out of sync but not when using the ATI video player.
Very strange!
What are you creating by the way?
vcd, svcd or dvd?

Thanks everyone for your help with all of this, I really appreciate it!

Okay, here is the Information on the file from VirtualDub:-

Decompressor - Xvid MPEG-4 Codec
# Key Frames - 840

min/avg/max/total delta frame - 89/4022/24677 (308661K)
DivX Quality - N/A

Audio Stream

Sampling Rate - 48000Hz

Hope some of you understand this because I find it a bit confusing

Thanks guys

I forgot to mention, I ran my avi file through gspot and it came up saying all codecs are installed. File rendered successfully, no errors reported.

Karen

[secretagent]

ok you have an xvid file and unknown tag 0055 which is mp3 audio
you will need to find and download and install the xvid codec. I don't have a link handy but if you do a search in the forums here for xvid codec you will find the link, or maybe someone will post it here.

[klm1702]

According to Gspot under the Video format it says I have Xvid MPEG-4 video decoder. For Audio it says I have MPEG Layer-3 Audio decoder.

Do I need to install something different?

I think it's under preferences, or maybe the compression settings but I'll check for sure when I get home.

I have no diea if this process will be the same for your video card, but...
...I have to run my ATI capture software first, before Virtualdub, otherwise it won't work.
You aren't running a dvd at the same time are you?
I got this message when I was ripping a dvd (I had the disk on 'pause') and opened up capture in virtualdub.
If you are, that's why

try this ,this maybe a round about way off doing things but it wrks for me and i have no prob's at all, i doit this way with audio which has ac3 & mp3 and has been coded with xvid video and i get know probs when loading audio or video in tmpgenc

u will need following programs which u will beable to find in tools section:

1. avi2vcd
2. virtualdub
3. tmpgenc

a) first off all u will need to decompress the audio, open avi2vcd load yr ie movie.avi file which u wish to decompress this will leave u a file something that looks like this movie_pcm.mpg.

b) open virtualdub then open file which u ran throu.. decompressor ie movie_pcm.mpg, save this to a wave format ie movie_pcm.wave

c)now load yr oringinal video file:movie.avi under video tab select full processing mode then compression here i select divx codec 4.12
then hit ok.

d)now select audio wave, browse to where u saved yr movie_pcm.wave..

e)press play in virtualdub and listen to see if yr audio is in sync with movie, if it is not press stop ,go to audio tab and select interleaving u can preload audio or not, here i usually untick preload audio and go back to virtual dub and listern to see if in sync if not go back to interleaving until u get it in sync,

f)once u are happy with audio and video being in sync just do save movie.avi this will take depending on movie size and cpu usually 700meg about 40mins..


now just load in tmpgnc and u will have no problems with tmpgenc saying unsurpported audio or video or module errors,,plus the audio and video will be from same source....

hope this wrks does for me..good luck

Of course you do, you would be looking at a blank monitor screen if you hadn't (and your computer wouldn't be running).
Go into control panel, system, device manager and have a look what your 'display' is, that should tell you what you have.
Let me know and I'll help all I can

Karen,

There's a specific version of virtualdub with mp3 support enabled. You'll need this because you're going to split the audio from the video. tmpgenc doesn't handle mp3 audio.

Open it in vdub_mp3. You may get an warning message about skewed audio sync from vdub, but just ignore it. Under the audio menu, select full processing and save the audio portion as a wav(Save wav..). The wav file will be as big as the entire video file, FYI.

In tmpgenc, select the avi as your video source and select the wav file as your audio source. Then encode and you should be just fine.

I've included a link to a similar discussion previously in this forum.

well...my 2 cents...maybe not even 2..

back to the orig prob...audio out of sync......

yes u can do all the above mentioned.....but when it comes to video editing ect. SPEED counts...according to ur computer profile you have a p2?? u need a p4.... i went from a 450mghz to a 1.6 gghz and it solved my tmpeg audio problems in 1 foul swoop ...mind u it cost $$$$$ but im MUCH happier, and video encoding, ripping, re-encoding ect. goes much faster with less problems

beside speed...RAM RAM and more RAM for video stuff!!!!!!

my 2 cents

thanks

Good point!
Sounds like three cents to me pal
I don't have any sound issues since I went from a Duron 800 to an Athlon XP2000+ but like you say, it cost me £££££££
