Problems importing into iMovie and which is the required space..

Question

Hi Karsten!
I could see that you know about video editing. And I have some problems and doubts I would like to ask.
The thing is that I have just bougth an ibook of 80 Gb hard disk RAM 512 MB Speed 1.67 GHz and I am trying to edit a documentary with it. The thing is that I started to importing images from a HDV 1080i Sony Camcorder into iMovie and the speed wasnt in real time, was slowing down to half of the original speed. I went to visit the help of iMovie it was saying when it happens is due to the desfragmentation of the disk, but I dont know if it is the real problem, it is a new computer, and how I can solve it.
And I also would like to know if I could have better results in the video importing and editing with an external hard driver other wise I could add more ram and more memory for the hard disk in the computer...
And the last thing, I would like to know how much space would I need in my computer for install and using Final Cut Pro and if it would be easy with more memory or an external hard drive...
Please Karsten or whoever who can have knowledge about these matter could help me. I really need it so much to start with my docu...
Thank you

"..which is the difference between FCP and FCE?.."
FCE is Final Cut Express, a cheaper and 'cut-down' version of FCP (Final Cut Pro).
FCE changes HDV (hi-definition) video into a slightly different format called 'Apple Intermediate Codec' when it's importing HDV material - just like iMovie HD does. This means that importing is generally slower than importing ordinary DV, because the movie has to be converted while it's importing. On a G4 PowerBook or iBook HDV might import at half-speed, or take even longer (..maybe 4x 'real time'), as you've found.
The latest version of FCP can import HDV, and edit it, without any conversion, Apple says. But I don't know if that applies on any Mac, or if that needs a special capture card to be fitted into a PowerMac. In theory, I'd expect that importing and editing HDV using FCP HD 5 (..the latest version..) would be faster than on a PowerBook - because there's no conversion involved - but I can't say for certain till I receive my latest version of FCP (..I just did an Apple "cross-grade" to convert my FCP HD 4.5 into FCP HD 5).
HDV doesn't take up any more room on a tape than normal DV, because the high-definition is 'squashed' onto the tape, using MPEG-2 compression. Because iMovie HD and FCE HD can't handle this kind of compressed material directly, they convert it into the Apple Intermediate Codec, and that form of the video takes up more storage on a hard disc than the normal DV does!
So although normal DV uses about 13 gigabytes of hard disc space per hour of running time, the converted HDV (..converted into 'AIC'..) takes up, er ..I'm looking for a recent project ..most are on an external disc ..are here's a simple one: one-and-a-quarter minutes' worth uses 904 megabytes; nearly 1 gigabyte! ..Here's another: four-and-a-half minutes' worth takes up 6.5 gigabytes!
Using normal DV, 6.5 gigabytes would hold half an hour's worth of video, not 4.5 minutes' worth!
So you will need a big external hard disc to store hi-def footage. At least, with iMovie HD or FCE HD.
I don't know if FCP HD 5 would store imported footage in the original HDV format, that is with the same storage requirements of ordinary DV - like HDV tapes. If so, that means that you could store hi-def (..if you're using FCP HD 5..) in just the same amount of space as normal DV ..but I don't know for sure. Maybe you could ask in the FCP Discussions. I probably can't tell you till next week or so..
Where to get a 300gb hard disc? I'm sure there must be at least one shop, or electronics store, in Istanbul which sells them at reasonable prices. Otherwise, look online. There are many companies which now sell 300gb discs: Maxtor and LaCie, for example. But you do need one with a FireWire connection; not just USB. You don't need to buy from an Apple store: buy one from any computer shop ..an external hard disc for a PC works exactly the same ..but you must format it for use with a Mac, as described before.
All I know of Istanbul is Cumhuriyet Caddesi, Taksim Square, and the areas around what used to be the floating bridge, and the Spice Market, and round Haigha Sophia, but there must be lots of computer shops somewhere in the city.
"..I have never used iMovie for editing, I understood it is only good for capturing, sample and concise.." and it's also good for transitions, titles, adding photos and audio, adding video effects and for audio tweaking. And it integrates perfectly with iPhoto, iDVD, GarageBand ..and now 'iWeb'.
