Wow, I never realized uncompressed video used THAT much space. I just imported 30 seconds as a test from my new digital camcorder into iMovie and it took 98MB. Does that mean one hour uses like 10 gigabytes? That's crazy!

anywhere from 3 to 9 Mb/sec.
I did a two hour project that ate up about 60 gigs. It adds a lot more with filters and trasistions.

I'm pretty sure DV is not variable bitrate, and it's always about 3.6 MB/s
obviously the real-world hard drive space taken is more for more complicated editing because any new rendering you do has to be stored as DV too

one second video has 25/30 pics! (pal/ntsc)
every pic has 700x500 pixel (estimate)
evrey pixel contains 8 bit of information
every minute has 60 seconds
every hour 3600 seconds
.... hm, what about sound…?
any questions ;-)?
just for hobby (i do 4 projects simutaniosly) i do use 500 GIG of hd!, cause you do need extra space for some photoshop jobs, you do need LOTS of space, if you do dvd authoring, etc....
video needs BIG hds.... ;-(

That's not uncompressed, that's DV compressed (5:1). Rule-of-thumb; DV eats up your HD at the rate of 13GB per hour. Not really that crazy - it's 4 times the data rate of an average DVD.
10-bit uncompressed runs at 26MB/sec, estimate 100GB per hour.
10-bit HD runs at 94MB/sec - 350GB/hr
Uncompressed editing runs expensive - big, speedy HDs needed!

In the FCP browser, it says how many m/sec and i mine varies quite a bit, the lowest is 3.5/sec
