An opening as episode zero
On this site an opening is simply an episode with a particular shape: one take per character, or two characters per take, each a short held moment in their own set. The sprinter in the stadium tunnel gripping a baton; the detective in the library with a notebook; the mage on the frozen lake with frost at her fingertips. Each take is six to ten seconds with a single line that sums the character up. Stitched behind the title card with eyecatches off, it plays as a brisk introduction of the whole cast in under a minute.
Number it as episode one and let the story begin in episode two, or make it the first episode of a new season when the cast changes.
Staging an introduction shot
Introduction shots want rim light, a held pose and one confident movement: turning to camera, catching a thrown object, pulling goggles down. Write the beat as a single movement and a single line. The anime scaffold adds bright rim light and bloom on every take, and the quiet-staging grammar (held expression, slow push-in) gives the pose time to register. For an action-heavy cast, add one verb and the action grammar takes over with speed lines and a held landing.
Keep the voice styles distinct across the cast: an earnest lead, a deadpan rival, a villain purr, a mentor calm. An opening is where those tags do the most work, because each character only gets one line.
The title card
Every stitched episode opens with a two-second card drawn on the spot: the episode number, the episode name and the show's title, on the site's warm-white paper with a sky band and a sakura rule. For an opening, name the episode after the show or after the season, and the card reads like the title plate of a broadcast series. The card is included in the stitch price.
What an opening is not
There is no music licensing here and no lyric track; takes are rendered with spoken lines and ambient sound. If you want a musical opening, render the takes with short lines or none and add a track in your own editor after downloading the episode file.
It is also not a trailer cut from existing episodes. Each introduction take is rendered fresh from the beat you write, which means you can give the opening its own sets and outfits (the festival yukata, the frost regalia) that the story has not reached yet. Viewers get a promise of where the show is going, and you get a reason to draw the wardrobe early.
