Flint was born in Northampton, England. He and his family moved to Bracknell Berkshire in 1994, where he attended primary and secondary school. In 2005 he moved to Dorking, Surrey, where he resides with his parents. He studied a BTEC in Media Production at the North East Surrey College of Technology, which ignited his interest in film-making. This led him to study a degree in Film Production at the University for the Creative Arts in Farnham, where he graduated with First Class Honours in 2012.
Since then he has started a career in freelancing, and is one day hoping to become a professional and dignified DoP, with a particular interest in narrative film. (2012)
