In my experience, Post-production is the make or break for a Documentary, but for a Narrative film, the make or break stage is pre-production.
If you are making a documentary, you are able to avoid much of the writing process and discover what your film is about by going out and shooting your subject until you have enough footage to create a compelling story during the editing process.
There is much more freedom to experiment during the process of making a documentary, or as Errol Morris explains, “What’s great about documentary, it seems to me, is that it can be experimental filmmaking.” You have a license to do a lot of diverse things under the umbrella of ‘documentary.’
However, if you are making a narrative film, the pre-production section is vital. The more you can plan out your film the easier the rest of the process will be and the better your final product will be. While this is a more vital stage to the success of a Narrative video, it is important in any video production. As Vin Diesel, yes Vin Diesel — Once put it, Quote, The majority of the filmmaking process is in pre-production. The more you’ve planned out the more freedom there is on set to find new stuff, to play around, find new jokes and let the actors kind of breathe – but it needs to come from a place where it’s completely structured.
