[Ronny Courtens] “You can put them in a nest to group them, but when you apply video or audio effects to the nest and then you break the nest apart again you also lose all the effects.”
Exactly. Technically *every* clip is a compound clip. The effect is applied to its “container”. Delete the container, you delete the effects. As long as you know that, you can simply use the Paste Attributes to reapply them after the detach… if you insist on doing it that way. But then I, too, would opt for the disabling of the audio in the channel configuration (or anything else) over detaching either way.
