large video size

[prmdoc]

I have downloaded my video clips from my miniDV, then
edited them and added music on MM2. My entire movie is
15 minutes. I wanted to upload it back to my miniDV
camera, and MM2 tells me that I need 3.7 gig of free
space for temp files. Why does it need so much disk
space? Also, when I initially downloaded my video clips
at the DV-AVI setting, it took about 900 mb of disk
space. Why so much for only 15 min? At this rate a full
movie such as Lord of the Rings should not fit on a DVD?
This is my first time doing this, so for give my
ignorance.

Thanks

DV-AVI files take up 12-13gb of hard drive space per hour of footage. That
makes 15 minutes.... yes, you've guessed, somewhere between 3 and 4gb. Your
PC (and MM2) is entirely correct in its mathematical calculations.

Almost all commercial movies are burned on dual layer DVDs... ie twice 4.3gb
which a single layer DVD allows for. Dual layer burners are now in stores.
Dual layer DVD disks will be in stores towards the end of next month and
will be approximately $6-10 each.

As a little extra, to capture your movie at 900mb, it could not have been in
dv-avi, probably WMV. Commercial disc manufacturers also have machines with
codecs worth many thousands of pounds, which allows them to reduce the
bitrate down quite low compared to home burnig and achieve amazingly good
results.
