Remove Black or White Background in After Effects

In this quick tip, we’ll take a look at how to remove a black or white background from our footage or images to get an alpha channel. We’ll be doing this without using any 3rd party plugins and will only be using built-in effects. This technique is very useful over blending modes in situations where you do not want to blend (either Screen, Add, or Multiple) your asset into the scene because they may be faded or blown out. This is also a nice way to “key out” the background so you can overlay the items nicely in your NLE without messing with blending modes.

Additional Tips

Another quick tip is to use a matte to cut out your objects, obtaining an alpha. Since your background is white or black, using a series of Luma/Luma Inverted mattes could be very beneficial. You may need to clean up the edges with a matte choker of some sort though. Red Giant also has a free plugin called Knoll Unmult which can remove blacks (not white). We cannot use Keylight to key out the black/white background as many beginners would assume because Keylight is a chroma keyer, meaning it only keys colors (RGB) and not black/white. I decided to do this quick tip while working on a project for a client. The client only had his logo on a white background. Using blending modes would’ve distorted the look of his logo, and I felt too lazy to hop into Photoshop to get a proper selection. By doing it this way, you’ll be able to stay within After Effects and avoid delay. This method also works with footage, something Photoshop can’t handle at the moment. I hope this technique helped some of you, especially using the presets. If you have any questions or comments, feel free to ask them below! Special thanks to Squarespace for sponsoring this tutorial.

  1. Can you make a tutorial about how to make the intro of Modern Warfare 3 ? 😀 That would be awesome lol!

  2. very new to AE, but is it possible to mask out a certain region to not convert white to transparent? specifically i have white text in the middle of my video that i want to remain, but everything outside of a rectangular bounding box i want transparent. this difficult to do?

    1. Usually you would have separate layers so separating the text shouldn’t be a problem. If it’s all 1 layer, perhaps apply the effect to an adjustment layer and mask the adjustment layer.

  3. For professional images I dont think that built-in tool is a good choice. Rather I prefer to do this stuff in photoshop using pen tool and clipping path technique.

  4. Hello,i saw your preset on youtube and its something i was serching for some while.Unfortunately i`m not using facebook or twitter.Is it possible to get the preset without it?Thanks

  5. Thank you verry much Son, anyway if i have a white wall at home, can i remove it quickly?
    Cam on!

    1. You can remove white using the preset, although keying out white is usually discouraged since so many things contain “white”. If you’re trying to key something out, try and grab a green screen or some other uncommon color 🙂

  6. This is really awesome tutorial man, i knew after effect only for animation work but this tool also can do background remove i really didnt knew it. And tip you given below in the video this is also very helpful for using this tool. And one thing is clear this work happened by very professional one, normal hand cant be able to bring this type of texture. This is really awesome work you have done. Want more like this.

  7. Not bad at all. The tutorial taught us how to remove a black and white background even after the editing. This is pretty tough because after when the editing is done the edges are tough to handle, they must be handled with great care to make it done.
