  scale diff size media to a constant value

  Posted by Antony Dupsta on September 11, 2015 at 12:03 am

  Howdy,

  Just curious if someone, (Dan) can point me to a solution for scaling footage to a fixed size.

  I have 6k, 4k, HD, footage… My current script scales footage to 25% of it original.
  .property (“Scale”).setValue([25,25]);

  The problem here is this is a ratio rather than a fixed size.
  So the result of the Poster image varies. 25% of the original.

  Can you suggest a way to set the resolution to a fixed Resolution. Something like 720×407. The constant is the aspect ratio, as it will always be 1.1:78 16×9.

  So any size footage (assuming 1:78) will scale to a fixed 720×407.

  Thanks for you help! Hope I explained that OK?

  It might be as simple as something like this:

  var s = (720/myLayer.width)*100;
  myLayer.property(“Scale”).setValue([s,s]);

  It is pretty cool you can do that…

  This works perfect and I like how you only set the width property to a value. This way I guess it does not matter what the aspect ratio is, this will maintain it with out squeezing it. Thanks!
