In drama, it's said that you write a film 3 times: in the script, during filming, and in the edit room.

In animation, there's less filming ("performance" being shared between the voice actors and the animators)... but the editing is constant. The bulk of the editing happens at the start with the animatic, to find the structure of the film in order to eliminate as much unnecessary animation as possible - but as additional detail is added, the edit must be revisited again and again.

The easiest way to illustrate this is to show you two simple sequences from Q Pootle 5, the preschool series I've just finished editing. Even though we used Redboard for the storyboard and the scenes were set up in 3D space with representative backgrounds, things can still change significantly. And, of course, it's still incredibly basic when compared to an animated shot.

Each video shows the animatic more or less as it went into the animation stage (albeit with notes from the producers), a playblast of the animation stage before it went to lighting, and the final version. I've included the full length of each shot from each phase, so there are black sections where there is no video to cover that part of the shot for that stage.

N.B. The animation stage shown is the trimmed version that was sent for animation approval - not the full length of each shot worked up which may have had overlapping actions or excess frames. It matches closely to the final version in terms of action, but the difference lies in the level of detail and any additional fine cutting. A useful additional stage would have been the blocking or early animation - but this wasn't available when I came to put this blog post together.

Example 1: from "Pootle's New Spaceship"

0:00 - Change of angle, changed early in the animation process to better view both characters

0:11 - Action changed to Ray (the bird) closing the nose cone rather than appearing, but the 'beat' of the action remains the same.

0:12 - In the animatic, I wobbled the image to indicate Pootle (green) and Stella (brown) climbing in to the spaceship. This action was eventually replaced by Ray's reaction and the sound effect.

0:23 - Engine start time decided in animation, but the false start matches timing. 

0:24 - Pootle's blustering was cut down in response to animatic feedback from the producers. The shot duration changed accordingly.

0:30 - Hugely different angle, hence different duration. The new angle allowed the point of the shot to be conveyed a lot more quickly.

0:36 - Filling in the animation and letting the animator work the shot as they wished resulted in different timing for this shot, with a more tentative lift-off.

0:40 - A much more cinematic feel for this shot than depicted in the board. Lovely - and a brilliant case for collaboration and encouraging everyone to not be afraid to try things out that are different to what's already there.

0:50 - It was decided after the animatic that Pootle should feel less hesitant about the instructions he's been given, and we shouldn't draw quite so much attention to how bizarre it all seems (in case he doesn't seem in control of the vehicle - preschool audiences aren't as appreciative of mild peril as older children!)

1.01 - End of scene trimmed. The starts and ends of scenes are easy places to add or lose time when cutting to an exact duration.

Angles changing between animatic and animation is a common thing - if there's time and it's a big enough change, new boards will be drawn up to illustrate the intended shot; but often it's quicker and easier for the director to just get it worked up in layout and changed to their specification.

 Example 2: from "The Cosmic Whipple"

0:04 - Adding the rock in the middle of the crater for Oopsy to climb up was a late addition, but added some action to the shot, and was a good opportunity for our most hyperactive character to expend some energy. Of course, this changed the framing a lot from the animatic. And the timing.

0:08 - Blink and you'll miss it: a minor trim to the final at a late stage. A massage of an earlier trim.

0:13 - Shot extended for new action. 

0:20 - There were several shots boarded for this short section of varying duration, but I ended up resizing them in the animatic and merging them at that stage. This accounts for the variation in line thickness and framing.

0:24 - Dead space cleaned up in the fine cut

Often, I would adapt a storyboard to use in an animatic, if it had an element I wanted. This could mean re-sizing, or using a part of a board to replace a part of another board to clarify timing. This often meant a note was added for animatic approval - but I kept my timeline organised to show that it was all part of the same shot, and the metadata reflected that. Sometimes an animatic would end up being the best approximation of the framing from the available boards - I'd put priority on the composition in terms of whether it was a 2-shot, wide, close-up etc.
