| Yes, as Dave said I am talking about firewire. Firewire transfers data and therefore there is not quality loss during the transfer. After editing the video I would store it on a DVD but if I need an analogues copy then I would send it back to the camera with firewire which instantly produces an analogue video output.
In any case, my argument is not there. I simply say that a dedicated card that assists in video editing or even one of the professional real-time video editing stations don’t do anything a PC can’t do. These cards/stations have special processors with a powerful instruction set for digital signal processing. They can do things faster (even real-time) but they all treat video as data that has to be manipulated to produce the result. The same algorithm can run on your PC and can produce the same result. It will just take longer.

aircombat, so here is what I know. Why don’t you tell us now what you know. How do these cards work that magically restore the pixels you cropped during rotation without quality loss.
John O, for information only... there is actually a camera that was developed at the place where I work (Rutherford Appleton Laboratory). It is not in my department so I don’t know the exact details. I am in the electron accelerator controls group. Anyway, I saw the camera in a monthly newsletter which I think it is still sitting on my desk. I’ll scan the article and let you see it. This is still a prototype. They claim it is portable and can be used to scan passengers at the airport to see if they have guns on then. The picture is more like an infrared scan, like the one at the old Predator movie. The camera works using low power Terahertz frequencies. It is therefore more like a radar. In theory it could penetrate a wall. |
