and that might be what you want to achieve creatively,

I'm going to zoom in in the timeline panel

我將在時間線面板中放大

so we can see the join between these two clips.

所以我們可以看到這兩個片段之間的連接。

And right now I have linking turned on on the timeline,

而現在我在時間軸上打開了鏈接功能。

so when I select one of these clips,

I'm getting its audio as well.

我也得到了它的音頻。

If I click this button at the top left

and then deselect by clicking

and this time I'm going to drag up over this edit

而這次我將在這個編輯上拖起來

to select it, it's the same effect really as clicking,

來選擇它，這和點擊的效果其實是一樣的。

and now I'm going to use a keyboard shortcut

If you press Command or Control + D

an audio cross fade, because it's audio.

I'm going to want this cross fade to be much longer
