Here is the error

❯ brew install homebrew/science/opencv --with-ffmpeg Error: No available formula with the name "homebrew/science/opencv" ==> Searching for a previously deleted formula (in the last month)... Warning: homebrew/science is shallow clone. To get complete history run: git -C "$(brew --repo homebrew/science)" fetch --unshallow

Error: No previously deleted formula found. ==> Searching for similarly named formulae... ==> Searching local taps... Error: No similarly named formulae found.

Try using this

$ brew tap homebrew/science

$ brew install opencv3 --with-contrib --with-python3 --HEAD

If the head shows headless or something just remove --HEAD from the end
