  BCC LED Filter: How to make a realistic glow

  Posted by Maxwell Federman on September 17, 2009 at 4:20 pm

  Hello

  The BCC LED Filter does make a very realistic effect. I am working on some new promos and intend to create a series of compositions wherein client’s content will appear to be showing on billboards, buildings, etc.

  I am curious as to which lighting effect I should experiment with to add a realistic “glow” to come off the simulated LED signs; since several of the background shots were shot at night. I have looked thru the Filter gallery but didn’t see any specific filter that seems like it would work.

  Thanks for taking a moment to read this post; I appreciate any help you have to offer.

  Hi Max,

  Here’s what I would suggest:

  • start by applying the BCC LED filter to the image clip
  • set the LED Gap parameter value to 2
  • set the LED Size parameter value to 6
  • set the Glow size to 10
  • set the Glow Brightness to 25
  • set the Brightness to 220

  Then add the BCC Colorize Glow filter on top of the BCC LED filter
  • set the Blur Amount parameter value to 10
  • then adjust the value of the Intensity parameter and you should have a nice glowing result.

  If you have a preexisting alpha channel, you can always use the BCC Glow Alpha Edges filter, or you can generate some alpha using one of the Keys and Matte category, precomp / nest, and and then use the BCC Glow Alpha Edges filter to generate a nice looking glow result.

  I hope this helps.

  Peter.
