View Full Version : Problems Burning AVIs

I use Nero, and when I try to burn AVIs to disk (VCD not DVD) the first thing it does is convert them to MPEGs. I also have a video converter that allows me to convert them to MPEGs independant of Nero. Whichever way I do it, the converted file suffers from a sound lag despite the fact that the original AVI didn't. I have found a program that edits video files called Virtual Dub wich will read MPEGs but won't write them. Using Virtual Dub I have found that if I adjust the frame rate of the MPEG it solves the problem, picture and sound in perfect harmony, but, as it only writes AVIs and therefor will only save to AVI, that puts me back to square one. I've now tried several video editing programs but can't find any that allows me to adjust the frame rate of a MPEG. By the way, syncronising audio and picture as I have found in many of these programs doesn't seem to work, it seems I really do need to adjust the frame rate. Anyone know of a good free (or at the least cheap) program I can get that will allow me to do this? :tilted :tol :wings :fire

I feel your pain.... Doesn't converting to mpg really reduce the quality of the picture?
There's a few standalone avi players available in the UK for pretty cheap. They will play all your DVDs, VCDs, and mpg, and avi files all in one unit. No conversion neccessary, no quality lost, no frustration!
But to address your question, I've noobed around with vdub a little myself, and it seems to be the defacto standard - I'm not up on too many other programs...
Have you checked www.doom9.org (http://www.doom9.org) and www.afterdawn.com (http://www.afterdawn.com)?

The audio of the original avi file was encoded in CBR or VBR? Did you also try TMPGEnc to convert it to mpeg1 (VCD standard)?

Just downloaded the trial version of TMPGEnc, and I keep getting the error message "Cannot load file...ect". Thanks anyway guys.
Anyone else?

You'll still need to give more information on the original avi file, do you also have a copy of GSpot?

What information do you need?
It plays just fine as an AVI in Media Player. It plays fine in Nero when I try to burn it. It's just when I try to convert it into MPEG in order to burn it the sound goes out of sync. I've tried a couple of other AVIs and they did the same. However files that I have downloaded as MPEGs work as they are supposed to and burn just fine. My problem is in the encoding process. I know the logical answer is to just download MPEGs, but they are getting harder to find. Maybe I'm missing a codec. Or if there's a writer that will burn AVIs without converting, that would solve it. But what I'm really looking for is a program that will allow me to adjust the frame rate in the MPEG and then save the edited file as an MPEG.
Haven't got G-spot, I'll have a look for it now.
Thanks for all help. :;) :gj

I stand corrected. I have got G-spot, I've downloade so many things in the last week trying to solve this problem I've lost track. However, I have no idea how to use it.

This might be a bit of a walk but here we go
Get a prog called avi2wav and use that to extract the audio from the avi.
this will give you a wav file exactly the length of the avi (ie:in sync)
Take the avi and use a prog called Vcd Gear to convert the avi to mpeg
this will convert the video but not the audio hence the need for a wav of said audio.
Then take TMPGenc and load up the mpeg as the video source and the wav
as the audio source and then reencode.
you should get an mpeg in sync
What might be happening is if your video is corrupt it might get caught up in nero
slowing down video encoding but not audio, giving you the audio gap.
This may or may not fix it if you have the patience
if this solution does not work then I am stumped too

OK, done that.

What the hell is that? I've just spent the last hour trying to figure it out and I feel that I know how to use it less than I did when I started. This is coming from someone who never reads help files because I can figure out any bit of software put in front of me better on my own without going to what I call the hinderence file. So this time I give up and look for said hinderence file, it takes a bit of finding I can tell you, then when I click on it nothing happens (it's the god of help files getting his own back at me for not having any faith in him, I'm Sure). Can someone help me understand Vcd Gear please.

At the bottom left hand side of the Vcd gear window you should have an option
to browse for a file, find the avi and load it up.
There should be a drop dopwn menu that will let you select avi to mpeg in the same area
select and hit start. I am pretty sure vcd gear does that type of conversion.
Hope it works :D

The reason I asked for more information was because VCD (mpeg1) uses CBR (constant bit rate) but if AVI contains mpeg2 VBR (variable bit rate) audio, convert them directly will cause it to be out of sync.! So, phuquit is right to have you convert audio to WAV or PCM first!

I can find nothing on the entire programe that mentions AVI at all. The only pull down menu I can find is in the top left corner, no mention of AVI to MPEG. When you load the file it only looks for RAR files unless you select the ALL FILES option. When you click on START an error message pops up saying "Source file could not be opened or accessed". Could there be 2 programes called VCD gear and I got the wrong one?

Well we did that with avi2wav..so he has the wav...I was sure Vcd gear did avi to mpeg...
damn....I know the error he talks about with TMPGenc too, used to get it every now
and again. Pissed me off and made me find ways around it like this but
if vcd gear cant do it......fuck you know what?
Try using TMPGenc and use the wav as the audio source
This is assuming you only tried to encode just the avi with TMPGenc
use the avi as video and wav as audio in TMPGenc and see if you get the same beans.
Its been a while since I used Vcd gear (used to extract mpegs from bins)
was sure it would work, apologies.
Try the above thought and see...

No need to apologise, I'm greatfull for all attempts to help. Anyway, what you're suggesting there is what I'm trying at this very moment. It's gonna take a while, I've got the encode going at the slowest highest quality rate possible, so don't hold your breath waiting for the results. I'll be going to bed before it finnishes myself. I'll report back tommorow.

OK, sorted. It seems, on that file anyway, all I had to do was encode it with TMPGenc at the highest quality then burn as normal with Nero. Thanks Guys, couldn't have done it without you.
