Don't know much about the flash-memory based ones, what format do these record in? Any recommendations?
Ok just did a bit of research and flash based still record in AVCHD or MPEG-2. If I just go for a SD are the file sizes going to be a lot smaller? 40GB/hr seems a lot!
AVCHD is always in HD. MPEG-2 comes in many flavors, including HD and SD.
If you're only interested in SD, then you have a couple of options. Flash, DVD, HDD, and miniDV. miniDV is out since you don't have Firewire. Of the 3 remaining, I would go with Flash for the same reasons as my previous post.
I think many of the newer SD-Flash camcorders record in MPEG-4, which iMovie can edit natively. Some of the older SD-Flash camcorders record in MPEG-2, which iMovie can't edit natively.
I would go with an MPEG-4 model. As for file sizes, it depends on the bit rate. The very popular Flip Mino records at 4 Mbps, which according to them equates to 2 GB/hr. I'm not sure about iMovie compatibilty, but I pretty sure they are. They are at least, Mac compatible.
There are plenty of other SD-flash camcorders from Panasonic, Canon, Sony, etc.
