From the After Effects Manual: When specifying the color depth for an output image, the plus sign (as in Millions Of Colors+) denotes an alpha channel. Similarly, choosing to output to 32 bits per pixel implies an output depth of 8 bits per channel for each of four channels: RGBA. May 10, 2018 The background is set to be transparent. When I try to import Gif with transparent background into After Effects, it didn’t work out, the background colour turned into white automatically. Adobe After Effects, Image with a transparent background have a box around it. I am trying to put a shine effect on the logo but the effect wont pass the invisible border around the image.

Keying out black backgrounds in After Effects is no problem with this quick technique!

While it’s always best to get pre-keyed footage, it isn’t necessarily difficult to key out elements on a black background yourself using After Effects. So if you have elements to key out, or you’re simply interested in keying out black backgrounds, follow these quick steps for great results.

Make Background Transparent After Effects

Step 1: Prep Your Footage

Before you key your footage, you need to make sure that your clip is a good candidate to have the black pixels removed. Keep in mind that this effect will remove all of the dark pixels in your scene in order of luminance. So, you may need to mask certain areas if your footage needs to have dark elements in it and still be keyed. I recommend adding a levels and curves effect without adjusting anything just yet. These will simply help us tweak the final key once we’re done.

Step 2: Add the Shift Channels Effect

Simply drag and drop the shift channels effect onto the layer which you want to be keyed. It should also be noted that this effect works with adjustment layers as well.

Step 3: Take Alpha From Luminance

In the shift channels effect, simply change the “Take Alpha From” checkbox to “Luminance”. You should instantly see your footage keyed out now. If not, make sure you toggle the transparency grid button at the bottom of your composition panel.

Step 4: Tweak Color Values as Needed

Using the levels and curves effects that we mentioned in step one, continue to adjust as needed until you get your key just right. Try different variations of curves and levels before and after the shift channels effect until you get it just right.
