"..I have a large internal hard-drive and two external hard-drives (250, and 500 GBs respectively), but I can still see that at 1 GB per minute, I would definitely have a storage issue.."
When I found that my G4 laptop couldn't cope with - was too slow at importing - HDV, I bought a "tower" desktop Mac with plenty of room for extra hard discs inside. I added one extra internal for storing photos and finished movies, and added a pair of very fast hard discs arranged as a 'RAID' (..two discs splitting storage between them..) for importing video onto.
So I resolved my storage issue by dedicating a separate hard disc (..or pair of them..) to hold iMovie projects, and then exporting, or offloading, finished projects onto a
third disc so that I could erase and re-use the 'importing' disc(s) ready for the next project.
I keep many finished movies on several other external FireWire hard discs which can be plugged in as required.
"..And what happens with those large files when I burn my iMovies to iDVD? Isn't there a 4.5 gb limit with iDVD?.." ..When you burn a DVD, iDVD automatically converts the movie into MPEG-2 format (..the format which is used on normal, standard-definition DVDs). So you don't need to worry about the
capacity of a DVD; the 'squeezed' or compressed MPEG-2 format can put 1 hr of best quality material onto a DVD, or 2 hrs of fractionally lower quality onto a DVD. So it doesn't matter that your hi-def video is many gigabytes large ..iDVD will compress it down to whatever running time - up to just under 2hrs - that you specify.
However, note that iDVD will compress it to
standard-definition instead of hi-def. By using Roxio's '
Toast' and/or its
hi-def plug-in you should be able to burn a hi-def version ..running for maybe 20 mins.. on a normal DVD, or a proper full-length hi-def version on a Blu-Ray disc ..as long as you have a separate Blu-Ray burner.
"..you do not have to use HD even though you are using a HD camcorder -- how does this work?.."
On all tape-based
HDV camcorders you can choose to shoot in hi-def HDV or normal DV. But if you shoot normal DV it's rather a waste of money - in my opinion - to have paid for the HDV facility and not to use it. Most (..all?..) AVCHD (memory card or hard disc) camcorders, however, shoot hi-def
only, so there's no option to switch down to standard-def.
"..I really don't know which camcorder to get.." ..That's another reason why I, and Forest and others, think that tape-based HDV is a better choice than AVCHD ..it gives you more flexibility, as in:
(a) You can shoot in hi-def HDV or in standard-def DV
(b) You don't need to make any backup 'archive' of your original material, as you'll always have the original tape on which you shot it. (..When memory chips or the hard disc inside a camcorder gets full, where d'you store all the material you've shot?..)
(c) A slight glitch on a tape may mean that you lose a few seconds of video and audio: if a camcorder's disc crashes - or memory gets corrupted - you may lose
everything you've shot on it
(d) The better, lower compression of HDV gives smoother, "truer" video than the higher-compressed AVCHD
..but against that, people may argue that:
(e) AVCHD memory-chip camcorders have fewer moving parts, so there's less to go wrong
(f) New MacBooks don't have a FireWire socket, so they do connect to USB-connection AVCHD camcorders but do
not connect to FireWire-connected HDV camcorders
(g) AVCHD camcorders tend to be lighter and more compact than tape-based HDV camcorders so they easily slip into a pocket (..though that lightness can give slightly more wobbly movies..)
(h) Chips and chip-capacities will become cheaper and greater, so that 32GB and 64GB capacity chips will enable huge amounts of video to be recorded on a single lightweight SD card, compared with the 1-hour limit of each HDV tape (..but see (c), above..)
"..I am leaning hard toward the HDR-HC9, but I am now a little scared about jumping into the HD world at all.."
..As long as you have a fast Mac, which you
do have, and plenty of RAM (..I'd upgrade your 2GB to 4GB if possible..) and a good size external
FireWire hard disc, for storing everything, you'll be OK.
HOWEVER, Canon camcorders do
NOT like to have other FireWire equipment in the circuit while they're being used. So a
Sony HDR-HC9 will happily work with an external FireWire hard disc connected to your Mac, but the equivalent
Canon HV30 won't ..that'll only import to your Mac's
internal hard disc.
Hi-def is already the standard, and with TVs getting bigger and wider all the time, standard-def DV looks a bit fuzzy now - and will look even more fuzzy in 5 years' time, when everything else will be far sharper! ..Just as no films are shown now in 'Academy' ratio (4:3 shape)..
..but in various versions of
widescreen..
..so standard-def home movies will look really odd in a couple of years' time.
So; AVCHD: small, handy, 'snapshot'-style hi-def. Simple slip-in (easily lost) high-capacity tiny memory cards. Expands to much larger file sizes when imported for
editing (..which the camera makers don't mention!)
HDV: a bit larger, heavier, slightly better quality, 1-hour-only small tapes, imports in 'real-time' with a fast Mac, expands to larger file sizes too.
Both use deceptively small "media" (tiny memory cards, or reasonably small tapes) which give no suggestion of the large hard-disc storage needed when you come to expand (..to enable
editing..) the compressed footage.
..As they used to say on "Blind Date" .."the choice is yours!"
