Hard disk space for video editing.

I would like to know why many people recommend a large hard drive for video editing?

i guess that my typical workflow would be to capture video form the cam which should take up 12.6 GB for an hour. I edit it and either burn it to DVD or compress it with DIvx or transfer it back to miniDV.

So lets say at a time I would not store more than 3 hours of video then why do i need a large 200-400 GB HDD?

Secondly can you all give me examples of your workflow like I gave mine above?

Thank You

Just some FYI:

A lot depends on how you capture the video from you MiniDV camera.
If you WANT the best quality, you the best quality setting! Makes sense!
Most programs the high quality setting is the default.
This will result in large files 10min will be about 2gb at this setting or 12.6gb per hour as you said, but they are compressed files! When you import them into your video editing program it must uncompress them to be able to edit them, now the fun starts.
The uncompressed data rate of MiniDV is 25mb/sec or 1.53gb/min or 91.8gb/hour, yes 91.8giga bytes. this is why you need a large hard drive. John

A larger drive will give you more working room. If you get the bare minimum amount of storage needed for a couple of tapes of video, you will have a painstakingly slow video editing process.

Also want to point out that the bitrate for miniDV is total about 36 MegaBITS/sec or about 4.3 MegaBYTES of data/sec. This equals about one GByte per four minutes or 20GBytes per hour of video. So, there is no 90.1 GBytes of storage space needed for one tape.

one last question.
what did people do when hard disks were smaller and hard disks of sizes upto 80 GB were luxuries. at that time they DID have DV cams so what did u guys do?
