    So this code resizes to 1/2 width and then resizes back to full width, with the result being a software extrapolation and blending? I was actually thinking about this.

    I also was thinking about resizing the 1440 scan width down to 780, but since no pixels are being extrapolated I assume all the noise detail would remain.

    This further confirms I need to stay with the s-video capture (I was wavering). I really believe a pixel-level compare (after SeparateFields) with the pixel above and below would eliminate 90% of the noise. I guess I need to learn C++.

    Yes. Note I added a second method using Blur().

    As mentioned numerous times before composite blurs the output since its bandwidth is limited compared to the Y/C source, If you smooth out or soften the noise you are washing out the details you can't have it both ways.

    Your capture card may have a frame synchronizer but I don't think it's built in TBC, Frame synch function is to add or remove frames to stay in sych with the source so you don't get audio delay or advance, A TBC in the other hand takes the v blanking signal and time correct it to an internal clock and output a new clean and timed signal. If you are sure your card has a frame synchronizer you can disable frame drop/add in the software or experiment with different combinations to see which one works best.
