How to convert video in camcorder to YUV file?

[snakefeet]

I got video recorded in JVC camcorder. Now I have to read each frame into MatLab as a individual picture(for transportation surveillances). Does it mean that I've to convert the video into YUV file and then to individual image?
My problem is:
(1)What's the video format in JVC camcorder
(2)I have 1394 firewall to transfer video to PC. Can you introduce me some software that can record only video. I use movie player to record data, but it contain both video and audio.
(3)After getting data, What software can help me to convert it to YUV file. There are lots of playing tools, but I just want the converted data stored as a file.
Thanks!

Transfer the file with WinDV/DVIO or any other DV capable 'capture' tool. Assuming your JVC camcorder does have a 1394 interface.

Load the DV AVI in VirtualDub, set video codec to Uncompressed RGB/YUV, set Audio to none, File save as.. ! Done.

Failing that get ffdshow, select it as codec in VirtualDub. Under the encoder tab select Uncompressed, pick the required YUV colorspace. Set audio to none again and save it as a file.

Prepare for HUGE files ;)

Thanks communist! But I want .YUV file or .Y, .U, .V file. VirtualDub save as... still in AVI format. I don't know AVI format's detail. What should I do after get uncompressed AVI file as you have advised? How extract .YUV file from it?

:-(. I must be a fool.

For that, it would be great if you know how to use VEGAS... you can also customize your video by using that software...
