Does anyone have tips on the best to key out black in a Florescent Sign?
Hi there
Basically I have filmed some florescent flashing signs at an amusement park so that basically it just black with the flashing signs. What Id like to do is get rid of the black and if possible change the letters into flat colour…so kind of use them as a mask with a solid behind them that they reveal? Does that make sense? A bit like the motel sign in this image https://www.timmarrs.co.uk/recent/rec_34.jpg
Any help would be much appreciated!
Thanks

The first thing I would try is to simply put the layer with the flourescent letters in Additive mode over your background. This is a common practice when you’ve got a high contrast, light, image with a dark background. Works great for explosions, pixie dust, flares, etc.. Good luck with it!

Is that just ADD under the Blending Mode section? Or do you do it another way?
Thanks

That is exactly it. Just make sure your layer is over what you want it to combine with. Here’s what the AE help says about ADD mode:
Add
Combines the color values of the layer and underlying colors. The resulting color is lighter than the original. This is a good way to combine nonoverlapping images in two layers. Pure black in a layer does not change the underlying color. Pure white in the underlying color is never changed.
