Anime Production Process

Mentioned Kikakusho / Pitch package of Neon Genesis Evangelion.
Settai
Settai is collection of model sheets and important places (can be a house, place or anything important). The designs go through multiple stages, so they can change over time. The final drawings are used by staff as the character standard. Depending on the budget, settai can have very high details.

Extra
Settai Dreams & Character Design References have a lot of model sheets. Visit these sites for more examples.
E-Konte
E-Konte / storyboard shows all the sequences in rough sketches so the director can show the vision to the animators and organize accordingly. It generally has 5 columns:
- Scene & cut number
- Scene rough drawing
- Animation instructions
- Dialogue & SFX
- Time & frame number
Formatting of a storyboard can change depending on the studio and director.

Extra
rinri posts a lot of stuff regarding storyboard. You can check out her posts there.
Genga
Genga means tie-down drawings or raw keyframes, drawn by genga artists. The drawn genga goes though a multi-step process.
Genga generally goes for important details of a scene. It can be just the character (or part of the character) or the character and their surrounding if the character is interacting with it. Genga doesn't generally include frame in-betweens, so it will be rough in motion by nature.
Short note
If you look at the sakuga, we can see a few numbers.
- 160 -> Scene number
- 01 -> Time (in seconds) of that scene
- 16 -> Shot number of that scene

Extra
We tried to really simplify the process. For more details, check out Dong Chang, Sakuga Foundry & Iwane Masaaki’s Animating Channel.
Timesheet

Extra
Free PDF book by Miyakawa contains a lot of info about timesheets / exposure sheets. Liss has been doing an unofficial English translation of the book. You can find a partial compiled version here and for the latest updates, click here.
Douga
More cleaned up frames, done by key animators. Dougas are way more completed and have more shading in general. The final animation looks pretty close to douga. In-betweens are also added in this step. Sometime, genga and douga can look pretty close depending on the artist.
