  FXScript frame variable

  Posted by Bob Wyttenbach on December 8, 2010 at 8:15 pm

  I’m delving into FXScript for the first time. I want a video generator that writes the current frame number on each frame. When I run this in FXBuilder, it works, with the number increasing. However, when I save the script as a plug-in, restart Final Cut, and put the generator on the timeline, the frame number stays at zero all the time (the duration is shown correctly). Why isn’t the frame number incremented?

  Here’s the script:

  float a, d, w, h, i;
  point framesize, fbox[4];
  string fnum, dur, lbl;

  resetText;
  fontcolor.a = 255;

  dimensionsof(dest, framesize.x, framesize.y);
  fontsize /= 320/framesize.x;

  setTextFont(fontname);
  setTextSize(fontsize);
  setTextjustify(kleftjustify);

  NumToString(frame,fnum,kInteger);
  NumToString(duration,dur,kInteger);

  lbl = fnum + “/” + dur;
  measurestringplain(lbl, w, h, a, d, aspectof(dest));
  makerect(fbox, 0, 0, w, a);
  drawstringplain(lbl, fbox, dest, fontcolor, aspectof(dest));

  Hey Bob, I’m a little too rusty to help you with your specific code, but…

  Have you tried inspecting the source code of the built in timecode generator/timecode reader effects to see how they go about accomplishing this?

  It took me a while to find and edit the built-in timecode generator, but that helped. I think the key was adding RenderEachFrameWhenStill before the code section.
