I don't see where you need to "capture" (Digitize an analog video signal

the output of your camera to work with.

I need the capture device for the 20-30 hours of existing video,
all of which is Hi8 or VHS.



There is a reason most VCRs only output over a composite
interface, and while your Hi8 is closer to S-VHS it's still
only ~420 lines.

**Caution the following is an opinion of mine that not all
here agree with**

Most corrections/improvements to an analog source are
best addressed while it is still analog, prior to its being
digitized.

The processing while analog should include TBC, then
the separation of the composite video signal into its
component analog signals and the application of NR to each
(as is appropriate), then the adjustment of the separated
RGB analog signals so as to effect any color correction
needed, and finally a "preamp" sort of strengthening of the
overall analog video signal.

*** End of the Heresy***

As a by product of this processing it is easy to output
the analog signal in higher bandwidth interface formats,
like S-Video and Component interfaces. (While the signal
is now cleaner and stronger, and these interfaces will
preserve that, the mature of the video material [such as
its ~420 Horz. TV line bandwidth] will remain the same.)
Still, equipment made to deal with higher quality S-Video
and/or Component Video is generally processing the video,
and made, to a higher standard; than that which is built to
process composite video.

If you are willing to spend the money on trying to extract
as much of a silk purse from a sow's ear as is possible,
then you should consider something like the Canopus
ADVC-300, and obtaining the best VHS playback deck
you can find/afford. For many, the amount of improvement
obtainable doesn't justify the added expense and effort.

If you truly only have these 20-30 to do, you might
want to look around and see if you can find a service
that will convert them properly for you, at ~ the $500
cost of an ADVC-300. (Good luck on that.)


As you are going to be working in MPEG anyway (HDV)
and the most available from your Hi8 and VHS is low
bandwidth SD, (converting it to 24Mbps DV AVI, won't
change that); You might as well consider capturing VHS
source material directly to the highest bandwidth MPEG
practical for SD material. In practical terms this will
normally mean to Main Profile/Main Level DVD
Compliant MPEG. Most HDV capable MPEG Editing
programs have made some provisions for having both on
the same timeline.

A quality DVD Recorder, at its best settings, can often
do as well or better than a PC capture card costing a
great deal more. By recording to a reusable media like
DVD-RAM or DVD-RW disks you can bring the video
to your PC for editing.


Luck;
