AVI to Mpeg ???

[boing]

I have two AVI files both in 4cc: xvid/MP3 format, I want to put them onto a vcd (one per vcd not both on a single vcd)

The first one is 585MB long and when opened in Tmpegenc ready to encode it says the finished output will be 645MB long, no problem there

Now the second one is the same 4ccvid/mp3 type according to gspot and is 644MB in length but after I have opened it up into Tmpgenc ready to encode it says the finished output will a whopping 1320MB

Why the HUGE difference?, why is the second one practically double its original length and is there anything I can do to acheive a much smaller file size with the second file?

MP3 VBR audio? That will cause that type of problem. Strip out the audio with Virtualdub as a WAV and encode the video and the WAV audio.

The file (I am having NO problems with) has audio that gspot says is 56 kb/s (28/ch, stereo) CBR

The second file (the BIG file) gspot says has 128 kb/s (64/ch, stereo) CBR

Anyhoo, after running the source avi through vitualdubmod I have stripped the audio and now have a wav audio (120MB)

Am I supposed to be compressing the original avi somehow?, I have just started virtualdub and choosen fast recompress, it says the projected file size is 5330MB and climbing???, is this right?

Hmmm, I think Ill abort virtuadub for now

Help lol
Now what?

For this I use VDMOD only for saving out the WAV audio. I don't do anything with the video, unless it needs filtering or resizing.

Then I put the original video into TMPGEnc and select the WAV file for the audio in. Then encode them both. I use MPEG-1, Layer 2 audio encoded to 44K for VCD. TMPGEnc should convert it for you.

Ive been thinking about this and it occurs to me that the avi file (644MB) is actually 'not bad' quality and the film is 2hr 30mins long SO I am guessing it isnt possible to compress it further?

2Hr 30mins of OKish quality inside 700MB seems good, am I right in thinking I cannot covert it to an Mpeg of similar size?


Bloody thing wont even fit on a dvd at 3000 bitrate lol
