Great stuff you have here. I am saddled with the task of setting up and running a small church video studio. At the moment I use a dell desk top with firewire, and adobe premire to capture from a panasonic 9000 HDV camera and capture real time. And its doing just fine. 1. After 1 hour service I get about 12gig size of footage. How can I get less with good video quality. 2. If I get additional camera what hardware or software will I need to do real time editing, capturing using the two cameras

Hey Fred, Great ques

Hey Fred, Great question. I'll do my best to give you an answer here. First of all, you may want to consider using a different capture method or buying a different camera so that you can ingest the footage to your computer faster than real time. Doing so will not only save you time but will save you the errors that HDV tape will inevitably have (such as dropouts, broken heads, timecode errors, etc). Using a different capture method will also potentially lead to smaller file sizes since, depending on their speeds, different mediums can capture to different formats. The HDV format is actually a very compressed video codec already but is unfortunately at a lower resolution (1440x1080), but there are other codecs that have a higher compression but still have a high resolution output. AVCHD, which can be found in most camcorders today, is one such codec. Though it will take more processing power to edit on your machine, it writes files that are much smaller and still at a higher resolution (1920x1080) than HDV. As such, I would recommend getting either an AVCHD camcorder or a device that can record from the FireWire output on your camcorder in AVCHD like the FireStore FS-H200, Atomos Ninja, and other DTE devices. Lastly, if you want to do real time switching and capturing using two cameras, I would suggest installing a Black Magic DeckLink card into the PCI-e port of your computer. This card will allow you to capture two independent video and audio streams and has plenty of connections. Telestream's Wirecast software can also switch between different video sources but cannot record a program edit. For an even higher end option, you could use a Tricaster Studio box that will allow multiple inputs and live switching. However, it costs quite a bit more than the other options. Grass Valley also sells a K2 Summit Media Server that would do the trick but again, it costs quite a bit. The bottom line is that it's not easy to combine a live switcher that is also a recorder in one machine. Especially in a computer using software. You'll probably end up having to use the computer as a switcher and then record the output from your video card on a separate streaming recording device (like a DVD recorder/player). Hopefully that helps!
