How to render an After Effects composition with an alpha channel and transparent background?Įxporting ,rendering a video with an alpha channel is actually very straight forward just follow these simple steps below. Hello, I've been making my own custom overlays inside Adobe After Effects and after rendering them with transparent backgrounds (RGB + Alpha). The alpha channel is used primarily in alpha blending and alpha compositing. If the value is in between, the resulting color has a varying degree of transparency/opacity, which creates a translucent effect.

If the alpha value is opaque, the source color overwrites the destination color if transparent, the source color is invisible, allowing the background color to show through. When a color (source) is blended with another color (background), e.g., when an image is overlaid onto another image, the alpha value of the source color is used to determine the resulting color.

That's how a professional would create an animated gif using After Effects.My simple definition of alpha channel, a colored image has 3 standard channels red,green,blue, the 4th channel is the alpha which allows you to control the opacity or transparency. Using After Effects, if the frame rate was only 10 fps you would have 600 frames. Using this technique you can create a 1-minute long animated gif that pauses on 6 different images for 10 seconds and has a 10 frame transition between frames that only contains 66 frames.

I don't even think the option should exist. Exporting an animated Gif directly from AE is not only inefficient, but you lose all control over color and dithering. Using this workflow you get the best color control, the smallest file size, and you have complete control. Export the Animated Gif using the File menu in Photoshop.Step through the timeline in Photoshop and set the duration of any frames you want to pause.
