Line TBC should nuke the timing wiggle at top of frame. It presents different in both cards, but still present, still bad.
Frame TBC should nuke some whole-frame movements seen.
The Tevion present slightly different person system, never sure why. Adjust internal card proc amp down by about -5 in the
VirtualDub settings.
That Elgato is severely overdark to the source, with some excess color bleeding. Appears to also drop frames not shown in the Tevion, though both are dropping (lack of frame TBC).
