Location plays a very vital role. If your story is based on incidents or a particular period, it needs to match the milieu. For that, you need to have the location locked with proper permissions and approvals.

Sometimes, you will have to push them to provide you with more if they offer little information as a response. You may need to record for long hours to capture the real deal, which translates to lengthy coverage. 

Consequently, you get to spend a relatively long time editing as you may have to cut a lot of parts, eventually. It could be minutes, hours, or days depending on the quantity and quality of the coverage and what you want to achieve in the end.

On the other hand, you have precise control when filming a movie. There is a script that serves as a manual throughout the entire process. In most cases, you will be dealing with people, actors, and actresses who know what they are doing and what is expected of them.

If it is about animals, you can improvise. The coverage and the movie ratio may be almost 50:50, especially if the retakes are few. As a result, editing will also need less time.
