Amateur recording movie shot in high definition initially earns Oscar (4,5)

'amateur recording' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'movie shot in high definition initially earns oscar' is the wordplay.
'shot' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'initially' indicates taking the first letters.
'earns' becomes 'e' (this might be a standard abbreviation which I don't know about).
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
The first letters of 'high definition' is 'hd'.
'movie' anagrammed gives 'omevi'.
'omevi' inserted into 'hd' is 'homevid'.
'homevid'+'e'+'o'='HOME VIDEO'
