I want to transfer a bunch of Video 8 (camera) tapes to Video CD for both
convenience and permanence reasons. My camera has analog output only.

From reading this newsgroup, it seems I should stay away from USB 2 capture
cards. Though lots of reputable manufacturers seem to have moved to USB 2
(Belkin, Hauppauge).

PCMCIA is good for me (laptop is convenient), but I'll go with PCI if
necessary.

Basic questions:

1. The PCMCIA cards I've looked at talk about 30 fps at 320 x 240
resolution. That seems very small. Is that really the right resolution to
capture my Video 8 tapes? Is 30 fps fast enough?

2. A quick calculation tells me this is about 2.3 Mbytes per second with 256
colours, or 4.6 Mbytes per second with 65536 colours. What speed,
resolution and colour depth would I need to achieve my goal?
(Trying to figure how much disk space I need.)

3. Am I wasting my time, or can I do this for around $50 to $100?

4. The Hauppauge USB Live II claims CIF 352 x 288 at 30 fps. Is this what I
want (even though it's USB)?

Thanks!

Yes, stay away from USB(2)

PCMCIA sounds scary to me. Go for PCI.

NTSC is 30fps, so yes that's fats enough. However, since your video is most
likely interlaced, I wouldn't recommend you capture to VCD (352x240), but
instead go for SVCD (480x480) as this format supports interlace. DVD burners
are also dirt-cheap these days, so why not go for this option instead?
352x480 offers an excellent compromise between size and quality, and is
legal DVD spec.

If you use a card withouy hardware compression, you would need quite a lot
of HD space. You can grab in several chunks, but anything less that 40gb
really isn't recommended. It is possible, though. I used to do video editing
on a P200 with 10mb HD space.

You can pick up a good capture card for well below $100. I use a Hauppauge
WinTV, which I paid around $40 for, and there are quite a few other brands
out there at similar prices.

It would be 352x240 at 30fps for NTSC. 352x288 at 25fps is PAL. You can use
those resolutions for VCD, but like I said, you are better off going for an
interlaced format, or your video will look rubbish, and you will need a
capture device that has a higher resolution than that.

Correction: 10gb :-)
