  • Color Bleed/Seeping Effect.

    hey all,

    i’m going to be doing a music video where color seems to seep or bleed through into white objects, walls, floors, etc. I was wondering if anyone has ever tried to pull off this look before, it would be similar to the effect used in Pan’s Labyrinth, when the little girl opens the book and the ink seems to paint and flourish itself onto the pages. I’m going to use motion tracking dots to get the perspective right, but I was just wondering if there was a filter, transition, plug-in, footage anyone has ever used to achieve the “seeping in, bleeding, painting of color” effect.

    thanks all!

    Hi,

    A real simple approach is a combination of roughen edges (to get a more random edge quality) combined with using a “simple choker” effect. Set the matte choker border to a high number so that the material to be bled in is gone and then animate its value to a lower number so it seems to bleed on. Use a blending mode such as darken or overlay to have it pick up background texture.

    I suppose this could be pre-comped with further masks to more specifically control where and when the “ink” bleeds on.

    Hope this helps,

    Lars

    The Transition > Gradient Wipe effect can be used to control the reveal very accurately. You will need to create a grayscale image to control what appears first, at 0% completion the entire image will be visible, at 100% completion it will be entirely transparent, as you move from 0% toward 100% the darker areas become transparent first.

    Here’s more info on that effect:
