Do some research and find videos that embody the same kind of content, mood or visual treatment that you want and share them with your producer. This will give them a good idea of what you want done and how you want it done. Best that you research a Singaporean company as the videos will be for a Singaporean audience.
Quantity is key here. Do not stop at 1. Selecting at least 3 videos will give your producer enough depth and variety to fully understand your needs.
