decrompressing sound with avi2vcd

[urbantus]

I have an avi on my pc which runs for 90 minutes

when i decompress it with the decompress proggy in avi2vcd it makes a new file which is only 23 mins long [pcm.avi]
Roughly only half the film is left

How can I compress it and get full length film

thx

[urbantus]

oops
I mean decompress it

Use Virtual Dub. Under audio choose "full process mode." Under video in "compression" choose "uncompressed rgb" and "full process mode." Then under file choose "save as avi." You will get a warning stating you are about to save an uncompressed file which will be very large. Click ok and then save your file. If you only want to save an uncompressed audio file under audio choose "full process mode", and under file choose "save wav." You will then have an uncompressed wav file. A better choice for saving an uncompressed audio file is a tool called goldwave.

that didnt work

i got a file 4 gigs big after 4 mins of film

Sp you want an avi with uncompressed audio but original video. Well, Laddydaddy was nearly right.

Open the avi in virtualdub.

Select:
Video->Direct Stream copy
Audio->Full processing Mode
Audio->Compression, PCM (none)
File-> save Avi

This will save a new copy of your avi with uncompressed audio but the original video stream.

Hope this helps

I now have a new avi file 1.5 gigs big

whats best programme to split it into two so i can make two vcds
thx

You can split the avi with virtualdub, or if you encode with Tmpgenc, use the source range feature to encode the one ivi file into two mpeg files.

[urbantus]

Did all that and ended up with two files ready for burning

Prob is my film now has bad lip synch problem and is unwatchable

[bugster]

Both parts?

How did you split, the Avi with vdub or with TmpGenc?

[urbantus]

converted avi with tmp genc

i set it so it would only do one half first as you said

it made me a new file

at first the lips were in sync but just got worse

[bugster]

A common cause of progressive sync loss like you describe is often caused by a framerate mismatch. Make sure you select a framerate in TmpGenc that matches tha framerate of the avi. Use vdub, File-File info to see waht framerate the avi is.

[urbantus]

from vdub
frame size is 25fps

[matneaves]

oi urbantus, did you read me guide in detail :P

defo true about frame mismatch, in vdub load the avi and then click file>file information and look top line will say either 25 or 23.967 or 29.97
which is pal/ntscfilm/ntsc

thats the same framerate you select in tmpgenc

[urbantus]

The above avi file has lip sync problems

the original avi was perfect

starting from scratch with the original avi how can i end up with a file or two that i can use to produce a perfect vcd

thx

[matneaves]

yep is 1.5 gigs because its now decompressed, dont worry about that at the mo as you will get yourself confused, beleive me i encoded a 15 gig, yes 15 gig avi to 1 vcd op 700 megs, with me guide

now load the avi into vdub and do the file/fileinformation bit and write down the fps (25.000,23.976,29.970) which in your case is 25 (PAL)

then goto audio/compression/none pcm

then save wav

in tmpgenc use the filmename_pcm.avi (your decompressed avi) as your video source

and the stripped wav as the audio

and go from there

[urbantus]

But the 1.5 gig file had poor lip sync

At the mo Ive split the original avi into two files using AVI MPEG splitter
I then decompressed both with avi2vcd successfully
I ended up with two files containing the whole film
Im now in process of converting each into mpeg using avi2vcd
Ill let you know how I get on

Cant think why I couldnt use decompressor prog succesfully with original avi
But it works ok when avi split into two files

Very odd

BTW I do want to use your way of getting a film onto one cd

But Ill try it on another film later

[matneaves]

that is strange, so let me get right your steps

you got avi and decompressed to create the _pcm.avi file and that was outta sync when played?

[urbantus]

At the mo Ive split the original avi into two files using AVI MPEG splitter
I then decompressed both with avi2vcd successfully
I ended up with two files containing the whole film
pcm_avi files

The lip sync is good

Ive then tried to change them into pcm_mpeg with avi2vcd
and there is lip sync

What can I do to these two pcm_avi files so I can end up with one or two cds with a viewable film

thx

[matneaves]

why are you using mpeg splitter

not needed

decompress original file with the decompresser it will create an avi called filename_pcm.avi, load that into vdub and then save wav with no compression (pcm)

http://homepage.ntlworld.com/matthew.neaves1/decompress.zip

here is the decompressor

thjen use that _pcm.avi for your video source and the saved wav as your audio

[urbantus]

As I said already
For some unknown reason the decompresor will only give me a file which runs for approx 28 minutes
My film should be 90 minutes
