Reshoot
Extracted from the Wikipedia article Pick-up (filmmaking).
Later editing
Pick-ups and reshoots themselves can pose significant continuity issues. For example, if the original costumers or makeup artists are unavailable (or if rented costumes and wigs were returned and original makeup supplies were entirely used up), then their replacements must study their predecessors' work, and precisely match whatever was used during the original film shoot.
