File size while capturing from Digial 8 camcorder

[javapro]

Hi! I capture video from my Sony Digital 8 camcorder (DCR-TV530) through FireWire using Adobe Premiere. Then I create a DIVX compressed AVI file with the following properties:

Video: 720 x 480, 24 bits, 29.97 frames/sec
Audio: 16 bit, 48 kHz, stereo

I get a huge file - 460 MB for 14 minutes of video. I have some DIVX movies that are only 700 MB for 1.5 hours of video with a pretty good resolution (can be viewed full screen easily with little distortion).

Why do I get such huge files? Am I doing something wrong? I am pretty good with computers but new to video capture.

P.S. I have P4 1.8 GHz, 768 MB of RAM, 40 GB HD, GeForce 2 MX 440 video card, SB Live! sound card

what version of DivX are you using and what audio codec??
it's probably your video bitrate is set too high for what you need though - try it again with half the bitrate you used previously and see what difference it makes to
the quality of the video
and the final file size
I'm guessing you won't see any quality drop and a huge size drop

When I used DivX(Various versions from 3-5), I learned that it works best at bitrates of 1mbps or lower.Anything higher than that sort of defeats the purpose of using divx because the quality/bitrate ratio drops and movies no longer fit on 1 CD.

also, the resolution of the 1.5 hour divx files most likely were not 740x480.. try making the resolution smaller.
