• In After Effects Software, it is an important
  aspect of motion graphics because you are going
  to want to render out graphics elements to use in
  a video editing app.
• With transparency, you can drag and drop the
  graphics files on top of your video tracks.
• Lets take a look at how to make happen in after
  effects software.

• Video files are made up of red, green and blue
  channels.
• There is a fourth Alpha Channel, but only certain
  video codecs can include an alpha.
• To add a sequence to the Render Queue in after
  effect software by default it will not include an
  alpha channel.
• It means your graphics will lack any transparency
  information in the final file.
• So how do we properly handle this thing in after
  effects?

• Let's figure out how to view transparency data
  inside the After Effects software.
• As with the exported files, After Effects by
  default does not show the transparency in the
  composition panel.
• Instead, see the background color of the
  composition.

12

• For changing the color
• Go to Composition gt Composition Settings.
• To instantly view the transparency in After
  effects software, click on the Toggle
  Transparency button at the bottom of the
  composition panel.
• If you want to view individual channels, you will
  also find a show channel button to the left.

• When you are exporting a file from the Render
  Queue After Effects software will default to the
  composition background color where transparency
  exists.
• To export with the transparency in after effects
  follow these steps

15

• Step 1 Add to Render QueueAdd sequence to render
  queue.
• To do this, Go to Composition gt Add to Render
  Queue.
• Step 2 Add Alpha ChannelClick on Lossless to
  bring up the Output Module Settings.
• Just Video Output, open the channels dropdown
  menu. Select RGB Alpha, then click on OK.

16

• Define where you want the file to output to click
  then Render.
• Step 3 Drag and DropYou have a file which
  includes the corresponding transparency
  information.
• Bring that file in video editing app and drag and
  drop it over the desired footage.

17

• Now that you know how to include alpha channels
  in exports, it's time to get back to creating in
  Adobe After Effects software.
