The “motion blur” technique, essential in animation to create fluid, natural transitions, can be applied to screenwriting to make moments of narrative transformation more organic.
What makes the movement of a cartoon fluid is, on the one hand, the 24 frames per second that break down the various positions of movements, and on the other, the slight blurring present in each still image on the edges of moving objects or bodies. Indeed, at 24 images per second, when filming relatively rapid movements, with each image exposed to light for 1/48th of a second, the edges of objects and the objects themselves appear slightly or very blurred (because they were moving during the time the shot was taken). You might think that this is a defect. But if each image were exposed to light for 1/1000th of a second, for example, and each image decomposing the movement was sharp (this is very easy to do in contemporary cameras), it would seem a priori more correct. But the movement would be, as we say, “stroboscopic”: the sensation of movement would be jerky, there would be no fluidity, and it would be extremely painful on the eyes. You can watch a few seconds of this type of movement, but beyond 30 seconds, it’s unbearable and you can’t watch the film any more. We reserve this for very specific effects.
So, for movement to be technically fluid and felt as natural by the viewer, there must be blur on the movements. This is well known in animation. For example, After Effects digital animation software incorporates the Motion Blur filter, which is always applied, and is one of the conditions for successful animation.
We can apply this concept of motion blur to the narrative itself, i.e. right from the script stage: when something moves, when there’s a transition from one state to another-be it psychological, mechanical, geographical, etc.-in order for it to appear natural and be experienced as such by the viewer, there needs to be imprecision, vagueness, surprise and incoherence in these moments. This is what will give the movement an almost natural beat-of-life dimension. If the movement is too perfect, it will feel mechanical, it will give an impression of rigidity, we won’t feel it as natural, and we’ll find it hard to believe.
So I encourage you to think about motion blur when writing a screenplay, at moments in the story when there are strong changes: birth, death, an encounter, a tipping point in the story.
Tools and Techniques for Screenwriting and Film Project Development.
In our world where artificial intelligences create films directly from the desires of their authors expressed in very few words, in this world where 3.5-hour films in dark theaters coexist with 10-second videos on social networks—which of these require screenplays, why, and what is a screenplay?
Is a screenplay still useful in an era where everyone carries in their pocket audiovisual creation tools of nearly professional quality? What is the purpose of a screenplay?
For writers, directors, producers, and especially content creators, as they are most often called today, I believe that the screenplay, its methods of creation, its writing techniques, and its ways of telling stories, is an extremely powerful tool to help us create the most impactful audiovisual works possible—works that will best connect with their audiences today and tomorrow, across their respective distribution platforms, whether in movie theaters, on television screens, on SVOD platforms, on community video sites, or on new media built exclusively around collaborative video like TikTok.
This guide does not claim to be exhaustive, but it is based on concrete experiences—those I have lived and those I have facilitated. For over 30 years, I have supported thousands of people in making films of all genres, founded and directed several film festivals, created numerous innovative events around audiovisual media, and also served on creative funding committees. What I share here is therefore subjective and practical, drawn from my journey and my observations in practice.
