What is Alpha Channel?Having an alpha channel will let you use your graphics in more creative ways.Before I ever touched Photoshop or Premiere Pro, I used PowerPoint for school projects. It amazed me that dragging a PNG file into the software made the white background disappear. However, as I advanced in my creative career, I came to learn that the white background wasn’t vanishing, it simply wasn’t there to begin with. See, when you view a PNG on a website or your desktop, you’ll note that the image’s background isn’t always the same color, but the color of the website/photo viewer background. This could be light gray or sky blue. This is because the website/software is populating the background information as it’s being told that element of the image is transparent. Adobe says,
That alpha channel, you’re going to want this if you need to lay graphics over other media files. Having a logo with transparency allows you to put it over anything you want. I always use the alpha channel in After Effects. Without it, graphics that go over videos—lower thirds, accent graphics, etc.—would need to be rendered out in their exact composition dimensions. Just thinking about that is giving me a headache. If you don’t render out the alpha channel, After Effects will fill in the empty space with black. How Do You Render with Transparency?First, see how much of your composition is transparent. Find the transparency grid under your main composition, and toggle it on and off. See any gray and white checkered patterns? Those are your transparent spots. Turning this grid on or off won’t affect the final render, it just allows you to see a preview of the final product. Step 1: Render QueueTo render a video with transparency, you need to add it to the render queue. So, under Composition, click Add to Render Queue. Step 2: LosslessNext, navigate over and click on Lossless. A window called Output Module Settings will pop up. Step 3: Output Module SettingsChange the Output Module Settings here.This is where you can change the codec, color depth, format, and channel. For transparency, you should be in the animation codec (or any other that allows the alpha channel to be exported). Note that some codecs do not support transparency or RGB + Alpha. There’s a red, green, and blue channel, then the fourth invisible one called the alpha channel. Transparency is the alpha channel. Once you pick the correct channel combination for your video, you should be good to render it out. RGB + AlphaYou can export the entire 4K video out with RGB and alpha channels.I love to use transparency when I’m exporting out lower thirds. If I correctly position the lower third in a 4K comp, then I export the entire 4K video out with the RGB and alpha channels. Doing this allows me to drag-and-drop the entire video into Premiere Pro without making any position changes. Of course, not all projects require you to render out the alpha channel, but it’s important to know what the alpha channel is and how to use it. Further quick tips from Adobe:
