Footwork of judoka caught in video recording (3,5)
I believe the answer is:
tap dance
'footwork' is the definition.
'judoka caught in video recording' is the wordplay.
'judoka' becomes 'dan' (both can mean a judo expert).
'caught' becomes 'c' (cricket abbreviation).
'in' indicates putting letters inside.
'video recording' becomes 'tape' (I've seen this before).
'dan'+'c'='danc'
'danc' put into 'tape' is 'TAP-DANCE'.
'of' acts as a link.
(Other definitions for tap dance that I've seen before include "Rhythmical entertainment" , "Rhythmic performance" , "Dent a cap (anag.)" , "moving performance" , "Source of rhythmic clatter" .)
