Interlaced rendering demo

E.g. 720p and 1080i require about the same number of pixels per frame. But with good deinterlacing, 1080i offers much better resolution for still images.

Problem is that your monitor doesnt have motion compensated deinterlacing.

If you rely on the eyes to do the deinterlacing then you will get a whole lotta flicker if you actually try to use 1080i without any vertical blur (and once you use vertical blur the advantage of the vertical resolution is a bit academic).

Motion compensated deinterlacing? Sounds like something I could get in dscaler, and I never liked dscaler's quality. Looked to always lose half the frames in 60fps source material, always had jaggy errors, was horrible for 640x480 source material as well, and at best would only approach the quality of a bad tv. Eh, at least it didn't have color bleeding.

what if your monitor is a CRT and your refresh rate is high (100Hz or higher). I think it would make sense to just display the interlaced signal.

I don't really see the point of interlacing then deinterlacing (unless you want to display 480i or 1080i TV material on a LCD or plasma panel), in my humble opinion you'd better either render "progressive scan" stuff for displaying in progressive scan or render interlaced stuff for displaying it interlaced.
