Fair use rationale:

• Purpose: the image is to be used in the article discussing EVL
• Nature of work: the original video is factual in nature, being documentation of work done at EVL
• Amount: the image is a single frame from a longer work, and also lacks the explanatory audio
• Effect: the use should have no significant economic impact on the original work (which is not commercially available, to the best of my knowledge)
