Nice, that looks very effective!

Thanks!

@Andrea: 843.75KHz is no magic number. I just chose it after some experimentation and enjoy that it's equivalent to DV's 4:1:1 horizontally, at least.

You can, for instance, get 675KHz with 72 (e.g., Spline16Resize(144, 480)) instead of 90.

675KHz gets pretty close to "narrow band" NTSC.

Do note that this is only for NTSC. You'll have to work out other numbers if you want to try it with PAL, but it should be the same procedure.
