I feel it would be more trouble to deinterlace footage than it could be worth. I know some ways can be bad. I only want to deinterlace still images so that I could post screenshots at larger sizes.
You've got me confused with the circuit board. Is this something you buy seperately or is it part of a motherboard, graphics card or something else?
...Oh I see, it's a chip that can either be in an external capture box or part of the capture card itself.
You don't need to worry about ranting about people on advanced video forums talking way over your head. I'm sure you're justified. And it's so helpful when they tell you to experiment with results. Cause who doesn't have a few hundred dollars to spend on an extra vcr that may or may not do better than what you already have?
Edit: Wait a minute. 80 gb for 30 minutes. That seems a little high. A 25 min video (of which the middle screenshot is taken from) is an avi file that's only 7.5 gb. Don't tell me dv compression can take away more than 7/8 the size and not leave any noticeable blockiness or compression artifacts.
