Large Mpg Size

[Crash1hd]

I was reading a post in hear that someone was able to compress a 1 gig file down to almost 650 mgs I was wondering how they went about that useing Tmpgenc as that is the program that they said that they used to do it with! I have a 798 mg file that is 91 mins long and I only have an 80 min cdr I am not really fond of the idea of overburning to make it fit on one cd! I know that I can cut it into to mpg files and put it on 2 cd's but is there a way that I can make it into 1 vcd without loosing a lot in the image quality! I mean the average movie is either 90 mins or longer!

Please help

You need to lower the bitrate to get it to fit on 1 disc. This will create an XVCD not a VCD.

Using TMPGEnc

Load the unlock template so you can change the bitrate.

Use a bitrate calculator so you can work out what bitrate to use to get your movie to fit.

Make sure under settings you set the video stream type to mpeg1 video CD (non standard). If you dont do this the mpeg will be padded out and will still not fit.

Then reencode.

There will inevitably be a reduction in quality due to the extra encoding process and the lower bitrate. Whether this is acceptable that is up to you.

If you have already encoded to VCD standard mpeg from an AVI file it would be better to encode the non standard mpeg from the original AVI (if you still have it) rather than the VCD compliant mpeg.

Just read your post more thoroughly.

A 798MB 91 minute mpeg file is not VCD compliant. A 91 minute mpeg VCD compliant file would be approx 910MB. So this file has already been encoded to fit on 1 disc.

Using mode 2 burning (which is what is used for (X)VCD) you can get nearly 800MB on an 80min 700MB CDR. I think it is actually 797MB, so you are only 1MB over, providing your burner supports overburning this will fit easily.

How would I know if my burner supports overburn! Its a liteon 48x12x48x

Also does it depend on the type of cdr that is used!

and in the nero over burn section it is default to over burn to 82 mins would I have to raise it to 92 mins?

Lite-on's are very good at supporting overburn. I have a 52x24x52. To get it to overburn I had to put a maximum overburn time of 98:58, I got this information here, although it is a bit dated now and only shows lite-on's up to 40x. I overburn to 99 min discs and slightly overburn 80 min discs (you can get about an extra 1-1.5min or 10-15MB (VCD) on an 80min disc, so your 1MB should be no problem), but if I put any time lower than 98:58 it would not overburn at all.
