large file size prob-xvid to svcd

[mufaa]

hi guys,
i am extremely new to the world of encoding.
after reading many guides from here and doom9.org
i couldnt find a problem i encountered with TMPGEnc
i am currently trying to convert xvid(ac3) to svcd with TMPGEnc.
the problem is that the final file size is like upto 1GB.
movie playback time is 1hr 12 mins 52sec.
orginial file size is like 700mb+.
is the file size(1gb) normal? how can i reduce it to fit in one cd and not 2.
i knw theres dvd2svcd software but i am not that statisfied with it nd i want to use/learn TMPGEnc alone.
i knw i have to cut the file into 2 but as u knw ac3 versions movies are usually 2cds and i wouldnt want to make 4svcd cds for the whole movie.
u understand wat i say here?
the thing is when i use dvd2svcd it makes one cd for one avi file like i want it to and can fit in one cd unlike TMPGEnc which makes very large file size.
the funny thing is dvd2svcd uses TMPEnc to encode but then it makes one cd,than i try to convert with TMPGEnc alone.

plss someone help me out here.plss feel free to ask any info from me concerning the conversion.

Quite normal.
82 minutes on one SVCD won't look good. A one CD VCD of 83 minutes might be possible to squeeze onto a 80 min CD with overburning.
You'll probably need a 90 min CD-R tho.
You can try and make a XVCD by lowering the audio bit rate (without much quality loss) to 192 kbps to make the XVCD fit a 80 min CD-R
There are only 2 factors that determine what file size to expect: Length of movie (time) and bit rate used for audio and video.
VCD is a fixed standard, the bit rates are fixed, but you can experiment with different bit rates if your player can play off specs VCD. But since VCD look pretty bad (old VHS tape) as it is, don't expect miracles if you lower the video bit rate.
SVCD has higher resolution, hence requires higher bit rates - don't go below 1800 kbps.
A compromize is CVD that is SVCD with a lower resolution - that may still look good down to 14-1500 kbps.
What looks good and not is individual - you have to make your own mind up what is acceptable to you.

Take a look at what is, to get info on bit rates and stuff for (S)VCD/CVD. Use a bit rate calculator to calculate bit rates vs time vs media size.

73 minutes is too much to fit on one SVCD. You could, but the quality would be lousy. Filesize depends only on the bitrate used and the length of the clip, actual size of the source doesn't really matter.

In TMPGEnc you can use the Source Range function to select which part of the clip to encode. Use it to select each half of the movie, this means setting up 2 encoding projects and you can use the batch encode function to do them in sequence. If you are using the Project wizard, then the bitrate setting screen will help you to select the correct bitrate to fill up your CD. If you are doing CBR encoding then I recommend that you don't drop your bitrate below 2000, this will give 45-50 minutes on a disk. At the last screen of the wizard select "create another project" to set uo the second part.

Good luck.
