Can I bi-pass "Capture" feature of VS X2 Pro

I'm finding the speed/performance of VS X2 Pro to be pretty poor, despite having a desktop thats a quad core 2.66 GHz with 4GB NECC Dual Channel memory.... I'm getting to the point that I'm close to buying alternative software.

I've spent a large number of hours stuggling with VS X2 Pro and am not seeing too much improvement with its response time when editing video foortage. I'm guessing it's largely due to the way I'm using the software.

Do I have to "Capture" the video footage direct from my camera - via the "Capture" tab in VS? I haven't done this, instead I've gone straight to the "Edit" tab and have opened the video files directly from my hard drive, as I had previously copied the footage directly from my 8gb SD card to my C drive.

I'm guessing this may be the cause of my speed issue because the files I'm working may still be fully compressed (compressed by Xvid codec & the audio is encoded using the MPEG 1 Layer II codec scheme). I read somewhere that a fully compressed file is more difficult to edit. (note: the video camera I have is not a mainstream camera. It is a POV (point of view) helmet camera. The resolution is 720 x 480).

If I was to use the "Capture" feature, does this feature decompress the original files via DivX and if this is the case will it make VS operate more efficiently when I am editing the footage?

No, the capture step is for one purpose only, and that is to get the video files from a source onto your PC. Since you already have your video files on your system there is no need to capture it. The fastest means for you is to do as you have already done, drag and drop the files.

The speed issue you're having is due to the source compression, (CODEC), Xvid. While this is not nearly as compressed as AVCHD, it is still a highly compressed format. The reality of video editing is that these highly compressed formats were never meant to be edited. They are meant to be the end product of a slightly compressed video format, DV (avi). However due to public demand, for higher-quality, and more distribution options, program developers were pushed into providing these formats in recording devices, and thus making their products capable of editing them. This does not necessarily mean that editing will be as easy or fast.

I guess you could compare how long it's taking you to edit and render your video files with that of Hollywood type animations like Shrek. Those take days, not hours, to render just a few minutes of video animation, on very, very powerful rendering farms. There are very few of these render farms. If you could buy one, or make one yourself it would only set you back a few hundred thousand dollars...;)

Even a Quad-Core system in comparison to professional systems, are very slow...
