A film editor of 30 years built an app so producers can follow the cut

A veteran film editor built a swipeable film strip that shows producers each sequence, its intent and running time as the edit happens.

After more than 30 years in the editing room, this editor knows the moment when everyone stops really seeing the film. Instead of accepting it, they built a simple app that lets directors and producers follow the edit and the reasoning behind it without rewatching a frame. It is a lovely example of deep craft knowledge turned into a working tool.

Tag Along - Follow your editor's mind

Before

For decades, this editor fought a quiet problem: people losing their judgment after watching the same footage too many times. On one commercial, the client debated how version 3 beat version 1 when the two were exactly the same. The editor tricked their own brain by watching with only their ears or changing pitch and colours. On long features and series, producers and directors often lost track of what came before and after what.

“They would go into long discussions about how version 3 was so much better than version 1, and they were exactly the same.”

In their own words

The turning point

In the program's AI project, they decided to tackle these two problems of cognition directly. They set up an Airtable that sits open on a second screen while they edit, logging every new sequence as it is added. They connected it to a Glide app so the people waiting on the cut could see it instantly.

“Countless times I watched the film only with my ears, or changed the pitch, or the colors, so that I could de-automate my brain.”

In their own words

After

Now they have a working prototype, a film strip for each cut that stakeholders can swipe through with a finger. Each card shows the keyframe, the sequence, and the editor's notes on what is happening and why. They already picture a version 2.0 that turns the edit into graphs to visualise the whole film.

What it lets people do

Directors and producers can see the order of sequences, their intent, duration, section and total running time without sitting through the film again. They save hours of rewatching, emailing and messaging, and stay up to date on where the edit is heading. A planned field lets them respond to the editor right inside the app.

What they learned

They learned that a problem they had lived with for 30 years could be solved with something very simple. The key was making the editor's thinking visible, so others know what path is being taken and why. A tool does not need every field on day one to show its value.

Picasso said that sometimes he hung his paintings upside down in his studio because he needed to see them with fresh eyes. Film editors often have to speak to producers and directors who simply don’t “see” it anymore. Once, I edited a commercial for Coca-Cola. The client and the agency were very demanding, but they simply did not see what I saw. To the point of me making three versions and showing them as if they were five. They would go into long discussions about how version 3 was so much better than version 1, and they were exactly the same. Sounds ridiculous? I know, but it’s true. If people lose their sense of judgment in 30-second commercials, how would they keep it on 2-hour films in rough cut stage? I’ve been a film editor for over 30 years. A few times, the syndrome of not seeing what I was watching hit me strong. Countless times I watched the film only with my ears, or changed the pitch, or the colors, so that I could de-automate my brain. Another huge problem in the field is being on the long journey of editing a feature film or a series for Netflix, and the producers and directors simply not knowing what comes before and after what. To solve these two problems of cognition, I am developing a very simple, yet extremely efficient app: the Tag Along - Follow your editor's mind (temporary name, of course!). In it, all the stakeholders can follow the edit without having to actually re-watch it. Just by sliding their fingers, they know what sequence comes after which, the intent, the duration, the section, the total running time, and the length of that particular sequence. As I am editing a film with the airtable open on a second screen, every time I add a new sequence, it’s registered there, and the producer and director can know instantly what path I am taking and WHY I am going that route. Having this close eye solves several problems. The precious time of the producer/director does not have to be spent watching and rewatching, emailing, and messaging the editor, and he/she/they can always be up to date on where the edit is going. Also, in a v 2.0, it can generate graphs to visualize the film. Unfortunately, due to time constraints of this context, I was not able to add all the columns and fields to the app but imagine that below the keyframe there’s the following info: - Sequence number - Running time at the beginning - Duration - Part, segment, story point - Scene description - Editor notes - and a field for director/producer interaction Please log in to the app here: https://editfollowup.glide.page Thank you for your attention and all the teachings!
