How to crossfade songs on iMovie ?
I wand to crossfade and overlap songs in iMovie like this;
but for this I need to add small video or photo to upper track, like this
My aim to create very long remix by crossfading songs (Don't worry its for my personal use), I only want audio, not a video
Is there any way to add 2 or 3 layers of audio without attachment of photo or video to upper track ?
