There are several key steps involved in commercial film editing, including:

Assembling the raw footage: This involves going through all of the footage that has been shot and selecting the best takes and shots to use in the final film.

Trimming and cutting: Once the best footage has been selected, the editor will trim and cut the footage to create a rough cut of the film.

Adding transitions: The editor will then add transitions between shots to smooth out the flow of the film and ensure a seamless transition from one scene to the next.

Adding visual effects: Depending on the needs of the film, the editor may also add visual effects to enhance the overall look and feel of the final product.

Adding sound effects and music: Sound effects and music play a crucial role in setting the mood and tone of a film, and the editor will work to select and integrate these elements in a way that enhances the overall impact of the film.

Fine-tuning and refining: The final step in the commercial film editing process is fine-tuning and refining the cut to create the best possible version of the film. This may involve making small adjustments to the pacing, adding or removing shots, and making other subtle changes to create the desired effect.

Overall, commercial film editing is a complex and time-consuming process, but it is an essential part of the film-making process that can greatly impact the success of a film.
