Get collection items from the same year as the current item

I had a little trouble filtering a collection to a specific year — ex: all of 2014.

These didn't work how I guessed:

# Nope
{{ collection:videos since="2014" until="2014" }}

# Nope
{{ collection:videos since="2014" until="2015" }}

# Nope
{{ collection:videos date:is_between:"2014-01-01":"2014-12-31" }}

So I found an alternative using a conditional inside the loop. Answer below.
