Final answer:
Film editing originally involved cutting and splicing celluloid strips with scissors and glue or tape, but this process has since been replaced by digital editing software.
Step-by-step explanation:
Upon its inception, editing occurred by cutting strips of celluloid with scissors and splicing them together with glue or tape.
This process, known as physical film editing, was commonly used in the early days of filmmaking before the introduction of digital editing software.
Editing techniques and technology have since evolved, allowing editors to perform a wide range of tasks digitally using software such as Adobe Premiere Pro or Final Cut Pro.
