The process may involve:
Screening all the footage to get a sense of what is available and what might be usable.
Selecting the best takes of each shot, based on factors such as framing, lighting, focus, and performance.
Creating a database or catalog of all the footage, including information about each shot, such as the camera used, the location, and any relevant notes.
Organizing the footage into a folder structure that makes it easy to find the clips needed for specific scenes or sequences.
Creating proxies or low-resolution copies of the footage to speed up the editing process.
