  Get text changes from CSV/TSV table

  Posted by Daniel Salaw on May 28, 2021 at 8:58 pm

  Hi guys,

  I am trying to link the values from a heart rate monitor to a text layer using an expression. I have a TSV file with the time in frames and the value. The table looks like this:

  timeInFrames	heartRate
  0	9
  75	96
  650	95
  800	95

  // etc.

  I didn’t manage to work with the TSV file, nor with hardcoded values, like this:

  if (timeToFrames() >= 0){text.sourceText = ’96’;}

  if (timeToFrames() >= 75){text.sourceText = ’96’;}

  if (timeToFrames() >= 650){text.sourceText = ’95’;}

  if (timeToFrames() >= 800){text.sourceText = ’95’;}

  Do you have a tip for me, how I can change the text automatically at the appropriate time?Thanks for your help!

  You can’t modify property values like that via expressions. The way expressions work is the property takes the last value from the expression. Try this.

  if (timeToFrames() >= 0){val = '96';}
  if (timeToFrames() >= 75){val = '96';}
  if (timeToFrames() >= 650){val = '95';}
  if (timeToFrames() >= 800){val = '95';}
  val
