'concealing' is the definition.
The definition and answer can be both to do with perception as well as being present participle verbs.
Perhaps there's a link between them I don't understand?

'some youtube clips ingeniously' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
