Add a subtle glow/diffusion effect to the highlights and deepen the shadows to hide static, un-rendered backgrounds. 4. Technical Summary: Software Toolkit for Editors
: Editors apply a slight unsharp mask or use AI-driven anime upscalers (such as Waifu2x or video-based neural networks) to recalculate the line vectors. This sharpens the character outlines and flattens color bands, restoring the original crisp, high-definition studio appearance.

This led to : stray vector points, unclosed paths, corrupted alpha channels, and “ghost frames” where a character’s limb would stop moving for 1–3 frames mid-action. In fan circles, this era is called Shinseki no Wana (New Century Trap).
Large portions of the animation were drawn "on threes" or "on fours," meaning a single illustrated frame stayed on screen for three to four frames of video. This resulted in a choppy 6 to 8 frames per second (FPS) during intense sequences.
