In 2022, the anime news site Anime! Anime! visited Telecom Animation Film during the production of the film Burū sāmaru (Blue Thermal). Each key animator drew a rough layout. The chief animation director, Tanino Miho, reviewed them. The corrections were added in three colors: green for the director, Tachibana Masaki, yellow for the animation directors, and pink for the chief animation director.
The key animators drew their key frames from these corrections. The animation directors and the directing staff then checked them again before they went to the in-between animators.
