  1. Discard half the scan lines; ie. make it "interlaced" , and deinterlace it with a simple algorithm such as "bob" .

    See my footage was 60i and I converted it to 60p using handbrake and bob but this still did not give me noticeable Aliasing to my footage, especially if my camera was not fully in focus, my main question is if there is some kind of filter I can add or any way I can control how much aliasing is in my footage. Also when I upload it to youtube it compresses my footage and makes the aliasing even less noticable

  3. Downscale and repeat. Downscale to SD, interlace/deinterlace/ and apply oversharpenen to generate halos

    When you upscale with a simple/poor algorithm, it will have severe jaggies

    Of course it didn't. Handbrake (and most other software) tries to avoid creating aliasing artifacts. Because nobody in the world but you want's them.

    Easy in AviSynth.

    Ok nice, what would I do in AviSynth to achieve this effect, I've never used it before.

  6. Something like this in AviSynth:

    Code:
    # load source, then
    SeparateFields()
    SelectEven()
    Spline36Resize(720, 576)
    Sharpen(0.0, 1.0)
    before:after

    If your source is very blurry you may need something more extreme. Using an unsharpmask filter:

    blurry source : after unsharpmask

    This is exactly what I was looking for, when I get back home I will make sure to try this.
