Titles and sound balancing are important aspects of pre-production. Dynamic titles created in software like After Effects or Photoshop can help set the mood, while balanced audio connections are needed for high-quality sound recording. Low-budget films can use hand-drawn or printed titles. Credits should thank all contributors and appear long enough to be read. Non-diegetic sounds like music are added in post-production for effect rather than being part of the story world. Foley artists record replacement sounds in a studio, while voiceovers can narrate or be added during ADR. Music establishes themes and mood depending on the film's genre and budget.
