Re: "webcam"
@TeeCee,
Yes, it's just a video camera, but I for one welcome the day when amateur film-making isn't tied to closed-platform camcorders.
First up: computer-controlled CCD+lens assembly can be synched with any other audio or video device you can connect to a PC. Currently only high-end cameras contain any synch circuitry, meaning editing of multiple sources is unnecessarily complicated as it relies on the old-school technique of clapper-boards and manual synch.
Secondly: camcorders have restricted storage/compression options. A miniDV tape can only store something like 15 minutes at broadcast quality. Solid-state and DVD cams record at compression ratios that leave the picture well below broadcast quality. HDD camcorders vary, and you're never quite sure what you'll get. If the camera provides an uncompressed HD feed, you're getting ever single thing the camera sees, which means you can rescale, recut, re-edit and compress and still end up with a broadcast-quality video.
Finally: reduction of redundant components. On any film shoot you generally have as many storage devices as input devices (audio recorders & cameras. If your software, your drives and your USB controller can handle the throughput, why not let them control more than one device. You're not only reducing bulk, but you're also making it easier to find related material.
