  Q:How to create RT fx & Drop Shadow in FXScript?

  Posted by Lars Fuchs on October 4, 2009 at 11:55 pm

  Hello all,

  I’ve created a simple script that adds a text label to a shot. Its based on the ‘Viewfinder’ filter. It works fine, but it won’t play back unrendered, while the ‘Viewfinder’ plays back fine unrendered. Does any one know what I should do so that my FXScript filter will playback in real time? I’ve pasted the code below. I’d also be grateful if anyone of you FCP gurus out there could tell me how to add a dropshadow option.

  Thanks in advance!

  Here’s the code:

  scriptid "Shotnumber" //DO NOT LOCALIZE
filter "Shot Number G"; //Based on "Viewfinder" Filter
group "Video";
fullFrame;

  input str, "Shot #", text, "S010";
  input fontname, "Font", FontList, "Arial";
  input fontsize, "Size", slider, 40, 8, 1000 ramp 80 detent 20;
  input scolor, "Color", color, 255, 255, 0, 0;
  input origin, "Location", point, -0.32, 0.28;

  InvalEntireItem
  RenderEachFrameWhenStill

  code
  float w, h, a, d, aspect;
  point framesize, originpt, poly[4];
  string snumstr;

  dest = src1;
  resetText;
  scolor.a = 255;

  dimensionsof(dest, framesize.x, framesize.y);

  fontsize *= framesize.h/640;
  setTextFont(fontname);
  setTextSize(fontsize);
  setTextStyle(kplain);
  setTextJustify(kleftjustify);

  boundsof(dest, poly);

  originpt = framesize;
  originpt *= origin;

  aspect = aspectof(dest)

  measurestringplain(str, w, h, a, d, aspect);
makerect(poly, originpt.x, originpt.y, w, a+d);
drawstringplain(str, poly, dest, scolor, aspect);

  Follow-up: on page 7 of the Using FxScript pdf, I found this
  

  Tip:
  It’s possible to create filters of your own that work in real time. You must make sure that the Realtime According To Budget option in the Real-Time Effects (RT) pop-up menu in the Timeline is not selected. This allows your own FXScript filters, transitions, and generators
  to run in real time.

  So setting my RT options to “Unlimited” (obviously the FXScript pdf I’m reading is a bit out of date!) gave me an orange render bar rather than red. Joy! Now, just need to figure out the DropShadow. Can anyone help there?

  Thanks
