I think you’ve missed my point, and focused on the tangent.
OP applies the Crossfade function (01). Behind the scenes, it extends the audio portion of the clips on both sides of the cut point and applies fades via the handles (02). If you then select Remove Fades (03), behind the scenes it removes the handle adjustment, but leaves the audio ends of the clips extended (04) and you can’t reapply fades using the Crossfade command (05), unless you first trim back the audio components to the original video cut point (06, 07).
It was not my intention to imply that the video cut was ‘the way forward’, simply an anecdote about an alternate way to crossfade en masse that you can readily see on the timeline without expanding components. And in/out fade types are adjustable in the inspector. Apparently, it’s too late to edit the post and remove the comment which is unfortunate, as it is poorly worded and implies much that I hadn’t intended.
If OP were to set the Audio Fade duration to the same value as Crossfade in prefs, then Modify / Apply Fades would operate on those extensions to re-apply the original Crossfade without having to trim them all back.
