How to add clips with video and adio fade-in/fade-out

Click the Media panel in the top-center section of the window, right-click to load the raw videos into the panel.
Double click the original video: it will be loaded into the Monitor (top-right section of the window).
Play the video in the monitor and select the IN and OUT cut points using key I and O.
Click the Append Clip button (or press the U key) to insert the selected clip into the timeline (the bottom-center part of the window).
Repeat the above two steps to add all the required clips into the timeline.
Add the fade-in/fade-out effect for both video and audio on each clip:
- Double-click the clip into the timeline: the Edit panel will be displayed in the top-center section.
- Using the + button at the bottom of the Edit panel add two effects:
  - Fade ⇒ Fade to Black In/Out
  - Audio ⇒ Volume
- The two effects will be listed into the Edit panel.
- Click the Hamburger menu button next to the Fade to Black In/Out filter and choose Open in Keyframe Tool.
  - A graph of the filter will be displayed over the clip into the timeline. Here you can add handle points and move them to change the line shape. The fade-in effect is obtained with a line starting from zero and rising to 100 e.g. in 2 seconds. A fade-out is obtained with the line starting from 100 and going down to zero.
  - Click anywhere on the timeline to close the Keyframe Tool.
- Similarly click the Hamburger button next the Volume and Open in Keyframe Tool to set the fade-in fade-out for the audio. Notice that normal volume is 0 dB and silence is -70 dB on the scale.
