ATI 600 USB for ADC vs Denon AVR-890 for ADC
A comparison to show what effect the AVR-890's inbuilt TBC has on VHS jitter. Both captures were made using the same VCR in Edit mode. For whatever it's worth, the Denon capture was made close to a year after the ATI capture.
Here are the AviSynth scripts I used on the source captures. My goal with the scripts was just to get them looking similar. When actually encoding this video for storage I'll bring the brightest parts down to 235.

Ugh, Imageshack has totally destroyed a bunch of the images in the first post. I would just attach them, but then they are gigantic to scroll through when there are so many (sort of like this post).
Anyway, a new comparison. Denon AVR-890 vs the "Xcard" from danno78.
First I captured with the Denon using its default proc amp settings (because none of its options are actually useful). Then I adjusted it a little using ColorYUV.
Following that, I attempted to match the Xcard's proc amp options to get an output close to the adjusted Denon frame. The bottom 8 pixels of all images here are masked off, and the Xcard frames are shifted down 2 pixels to match the alignment of the Denon.
Xcard - sharpness 110
Xcard - sharpness 115
Xcard - sharpness 255 (cranked way too high)
I like the available contrast latitude of the Xcard better than what the Denon offers, but sharpness and detail are irking me. Somehow Denon seems to give the most "natural" sharpness level and has more detail. Maybe I'm imagining it. The detail I'm seeing is in the small diagonals of the ANIMANIACS logo: A, N, M. On the Xcard shots, the "Weekdays!" text appears to have little dots inside the text that aren't there on the Denon shots.
I've updated the OP so that it's actually useful again. The messed up ImageShack links are gone and replaced with thumbnailed attachments. Took forever because the darn image uploader spits things out in a random order!!
