Problem
After adding music to your videos, we can also edit the audio and add some other effects. To combine the video and audio more naturally, we can fade audio--to fade in or out audio according to your needs.
Solution
With Camtasia Studio 5, you can easily fade audio. Here we take fade out audio for example.
Use the same operation to fade in audio.
Tips
If there is more than one audio track on the Timeline, when a selection is made on the Timeline, all of the audio tracks will be affected by the fade in and out properties that are applied.
