Abstract: The visual quality of archival videos is shaped by degradations introduced across the stages of their lifecycle and corresponding enhancement methods. This survey consolidates research on restoration and enhancement techniques spanning the capture, content creation, content delivery, and content consumption stages. Beyond stage-specific approaches, the survey also reviews emerging all-in-one frameworks designed to address multiple degradations jointly. By unifying these perspectives, it offers insights for developing pipelines that enhance visual fidelity while preserving historical authenticity.
