Pixmap Plugin After Effects ⇒ «EASY»

Pixmap plugins are excellent for transitioning from abstract data to concrete footage. You can use a map of pixels to display statistics—where each pixel represents a unit of data—and then transition those pixels into a video image. This is a common technique in tech documentaries and explainer videos.

Define a slider for blur radius:

static PF_Err 
ParamSetup (PF_InData *in_data, PF_OutData *out_data, PF_ParamDef *params[]) 
    // Blur Radius parameter
    PF_ParamDef blur_param;
    AEFX_CLR_STRUCT(blur_param);
    blur_param.param_type = PF_Param_FLOAT_SLIDER;
    blur_param.u.fs_d.value = 5.0f;
    blur_param.u.fs_d.min = 0.0f;
    blur_param.u.fs_d.max = 50.0f;
    blur_param.u.fs_d.precision = 1; // one decimal place
    PF_STRCPY(blur_param.name, "Blur Radius");
AddParamToEffect(in_data, &blur_param);
return PF_Err_NONE;

Then read the parameter during render:

float blur_radius = params[BLUR_RADIUS_IDX]->u.fs_d.value;
