Tutorial Transcript

In this tutorial, we will show you how to import your audio and mix it to your template.

First you have to open your project. Select the audio file of your choice on your computer and import it in the Project panel. Then drag it into the RENDER THIS composition. If needed, you can see the waveform of your audio file : simply select the audio layer and hit the L key twice.

If your audio file is longer than your project duration, you can adjust the audio levels to create a fade out. To proceed, place the time locator approximately one second before the end of your composition, and click on the Level key frame. Now go at the end of the composition, click again on the level key frame but turn it down to the minimum of – 48dB.

If your audio file is shorter than your composition, you can loop it with After Effects. Here is how to proceed : in the Project panel, right click on your audio file and select Interpret Footage. On the bottom of the window, you can set the loop options. In our case, we will repeat the audio 5 times. You are now able to extend the audio layer in the RENDER THIS composition to fit with your project duration. You can again add a fade out at the end of your composition for a better result.
