HUGE wav file

[maynardjames]

I am trying to encode a 500 meg movie (knockin on heavens door) into an mpg for a vcd. I have about a gig of mem left but when i try to encode this file the wav uses it all. I don't think a 110 minute wav file should take 1 gig. Can anybody help me?

For a 110min movie, an uncompressed wav file will be about 1 gig. Here's the calculation:

1 MB of 16 bit, 44k stereo wav file = 5 seconds of audio (approx).
so
12 MB = 1 minute of audio

For a 110 min movie with uncompressed wav audio,

110 x 12 MB = 1320 MB of audio.


Remedy:

Re-encode the wave file as an mp2 or mp3 and re-multiplex it to your DiVX (?) movie. The resulting mp2 or 3 will only be about 100 MB for a 110 min movie.

Sorry, I didn't read the question properly

I think I see what is happening. Is your source AVI a DivX? If so, they will always re-encode much larger to mpg - well over 1 gig for a 110 min movie. That's why people use divX. Unfortunately it's not compatible with DVD players.
It's not the audio that's hogging the space in your resultant mpg file. Its the video component. About 80% of the total mpg is video in an mpg-1 file. The audio component will only be about 200 MB

I'm sorry i probably should have been more specific, when Tmpgenc starts (i use toolame) it says at the bottom "Creating Temporal Wav File" and at about 65% i run out of space. I am pretty sure it is a Divx file but i am pretty stupid about that (it says mpg4 under the codec collum in Morpheus).

OK, I see now. What you need to do is not use TOOLame for the audio conversion. leave that whole audio compression option blank, not linked to any external audio encoder. TMPGEnc will automatically use its own internal converter which will take the source audio from the mpg4 clip and convert it to mpg-1 audio (which isolated by itself is mp2 compression). This is provided you use load the standard "Video CD (PAL)" or "Video CD (NTSC)" template that comes with TMPGEnc.

Be aware, though, that you'll still use up your disk space, because a 110 min movie converted to VCD will still be about 1.2G, 80% being the video data. Break your encode session up into 2 parts, the 1st part of the movie about 70 mins long, the 2nd one with what's left over, then burn them to 2 CD's. Full length standard VCD movies NEVER fit on one CD. That's just the way it is

Thanks for the help. What i ended up doing was cutting the Divx file into two pieces, put one on a CDRW then i encoded the other. It actually worked quite well.
