Final answer:
A one-sentence summary of a film project is called a log line, whereas an elevator pitch is a quick professional verbal introduction designed for networking and interviews.
Step-by-step explanation:
The term for a one-sentence summary of a film project is a log line. It is designed to provide a quick insight into the story, capturing the essence of the plot and its unique aspect in one concise statement. An elevator pitch, on the other hand, is a brief professional introduction used in networking, cold calling, and interviews. It's a quick, persuasive speech that sparks interest in you and your background and it is typically longer than a log line. While a portfolio showcases a collection of work, plosive is a phonetics term and does not relate to film at all.
