Not sure if this helps, but I want to capture pixel perfect captures and I've been reading up on Integer-ratio scaling.
This article seems to help shed a lot of light on the subject.
Integer ratio scaling and line doubling/tripling, etc are essentially the same thing . The OSSC is a great tool for generating integer-ratio scaled video from a vintage/retro PC or console's output and minimizing (sometimes eliminating) the amount of actual non-integer scaling that a typical monitor (usually do not fo integer-ratio scaling) has to do, which results in a sharper image .
As for capture, high quality pixel-perfect capture can be done with a card like the E1S directly . Alternatively, you can combine an OSSC and E1S, if you like (which is what I am doing, for now) .
