OpenToonz was utilized for pencil testing by animators and a director.
Studio Chizu had used another software for pencil testing. They decided to migrate to OpenToonz for the production of "Belle" after hearing successful precedents of other studios.
They put camera stands on every drawing desks so that the animators can check their own animation on the fly. For animators working from home they also built the same environment at home for pencil testing.

Comments from staff in the studio:
"Since OpenToonz was more stable than the conventional software we could use it for production without any critical problem. The animators had learned to use the software relatively quickly. It is a user-friendly and powerful tool."

"Natsuzora" is a television drama series depicting the life of a heroine who becomes an animator in the early days of Japanese animation industry. OpenToonz was utilized in the production of the opening titles and many of the animated sequences to process effect compositions and cinematography.

Comments from Yoichi Senzui, the director of photography:
"I decided to use OpenToonz considering that it is useful for inputting the Xsheet and also it is easy to modify the painted drawings. During the production I could start creating the scene in parallel with ink & paint work. And in case there were adjustments in animation drawings, we could handle the changes seamlessly in the same software. So, using OpenToonz was timesaver."

OpenToonz was utilized for pencil testing by keyframe and inbetween animators.

TRIGGER had been introduced OpenToonz for pencil testing since the production of "Kiznaiver". In "Promare" production, OpenToonz was used not only by animators for checking thier own work, but also by an animation director and a director for checking and modifying timing of all animation footages.

OpenToonz was also utilized for "線撮"(Sensatsu, line compositing) on a trial basis. "線撮" is a workflow of making pre-visualization movie by using intermediate materials, which is to be used for post-production in case the production runs behind schedule.The clapperboard feature and the time code fx were newly developed and introduced for that purpose.

The camera capture feature of OpenToonz was utilized for pencil testing by keyframe and inbetween animators. It’s notable that the camera capture feature was originally demanded by the director Kitaro Kousaka and introduced to the production for the first time.

In one of the triple feature ”Invisible”, OpenToonz and GTS were utilized in all digital workflows including scanning, color designing, ink & painting, and compositing.

BATMAN NINJA is an animated film created mainly by 3DCG. However certain scenes incorporate traditional 2D animation. OpenToonz was utilized in the production of those scenes to process strokes, effect compositions and cinematography (e.g. camera works). One of the reasons why OpenToonz was chosen for this film was because it processes drawing in a special format which preserves the halftone information required to replicate the natural look of a pencil’s stroke and subtle faint lines. Additionally, OpenToonz uses a palette system which enables the user to work flexibly - a user can for example work on the cinematography of materials before the colorization process or change the color specification without having to go back to the finishing process.
