Renu was born into a Punjabi Family. Her family always supported her and encouraged her to pursue a career in Hindi Film Industry. When Renu applied to the Film and Television Institute of India Pune in 1974, editing was only her second choice. She had applied for direction and did not get through the direction interview. But she did pass the editing interview and was persuaded by her parents to go ahead with it. She finally passed out of Editing course in 1976, and entered the hitherto all-male bastion of film editing in India. Sify.com, 2009-03-12.
