MPEG2 offers the best quality in relation to file size for capturing video.
DV or otherwise know as DIGITAL VIDEO will need 4 GB for every 20 minutes of video. DV is
good for some applications, when you want to capture in DV, Edit in DV and OUTPUT back to
DV. (Back to camcorder). This is why you need firewire for DV. The data being sent back and
forth from a DV camcorder is huge. 25 Megabits per second, thats 3.6 Megabytes per second.
With the USB Instant DVD for Mac, video can be captured at relatively low bit rates but VERY
GOOD quality. For connecting to your Mac, USB 1.1 as an interface is sufficient since USB
offers up to 12 Megabits of throughput per second. Plenty of bandwidth to capture video with
DVD quality.
If you plan to make DVD or VCD movies, USB Instant DVD for Mac is the perfect solution. It
captures in MPEG2, which means you are one step closer to making a DVD disk. Just run
CaptyDVD and author/publish the captured video to DVD.
Other DVD authoring/publishing solutions like Apple’s IDVD software actually capture the video
in DV. It then transcodes, in laymens terms, saves the file as an MPEG2 file. This is a two step
process. Although the transcoding process via software is done very well, it is no comparison
to capturing your video source REAL TIME into an MPEG2 File.
