Which process would most likely be conducted during post-production?

The process of editing and color correction is a crucial step that takes place during post-production. This phase occurs after all the footage has been shot and involves piecing together the recorded material to create a coherent narrative. Editing allows filmmakers to select the best takes, establish pacing, and incorporate visual storytelling techniques that enhance the film's overall flow.

Color correction further enhances the visual quality of the film by adjusting the colors and lighting of the footage, ensuring consistency across various scenes, and creating a specific mood or atmosphere. Both editing and color correction are vital for refining the film and preparing it for distribution, making this choice the most appropriate answer when identifying processes specific to post-production.

The other options are associated with pre-production or production stages rather than post-production. Principal photography is the actual shooting phase, casting is done before filming to select actors, and location scouting involves finding and securing sites for the shoot before any filming occurs.
