Re: Is FireWire worthless/obsolete?

If you use the right search terms, you can find examples of people
who capture, via the Firewire port, live video from their camcorder.

With the wrong search terms, you can find totally bizarre and
difficult to believe stuff on the Internet.

Some of the high end camcorders now have HDMI outputs on them, for
the same purpose, but you need an HDMI capture card (Intensity
Pro) to use that.

There are also industrial cameras that use Firewire. This one uses
1394b or Firewire 800, and captures 1600x1200 at 15FPS or 640x480
at 90FPS (the latter figure not stated in this advert, but stated
elsewhere). That translates to more than 80MB/sec (assuming 24 bit
color per pixel). The lower resolution is done via high speed
binning (ignoring some of the pixels while clocking out the data).

There is a company in town, where I'm living, that makes high res
Firewire cameras, like that Sony example. So Firewire is still
alive and well for niche applications.

USB is preferred for high volume items (webcams for <$100),
because you can find a decent USB port on virtually all new PCs.

Camcorders that cost thousands of US dollars use USB.

My mainboard has FireWire ports. As far as I know, WebCams are the
most likely user of FireWire on a personal computer, but almost none
use FireWire. So one might guess that it's nearly obsolete for
personal computing.
