How AI BL Gets Made: From Script to OST

blaiva Editorial Team · November 2, 2026

When you hear "a drama made by AI," it's easy to imagine a video popping out at the push of a button, but in reality it takes a great deal of human effort. We've gathered what creators have shared in their video descriptions and production notes to outline the order in which AI BL dramas are usually made. Every channel works differently, so please read this as a general flow.

1. Story and Script: Written by People

Many channels emphasize that their stories are "original scripts." The character settings, the events of each episode, and the dialogue are mostly written by people themselves. Because AI video is generated in scenes that last only a few seconds, it's important to break the script down into very small scenes at this stage.

2. Character and Scene Images

Next comes the stage of creating the characters' faces, costumes, and backgrounds as images. The same character has to appear with the same face in every episode, so the key technique is to settle on a reference character image first and keep that face consistent from scene to scene. For a historical drama, this is where you decide on things like the colors of the hanbok and the accessories; for a fantasy, symbols such as eye color.

3. From Image to Video

The finalized scene images are brought to life with a video generation tool. Creators generate a few seconds of motion, like turning a head or fingertips touching, dozens or even hundreds of times, then pick the ones worth using. In the production notes on the blaiva listings, tools such as Seedance, Higgsfield, Kling, and Veo appear often.

4. Voices and Music

Dialogue is sometimes recorded by voice actors and sometimes produced with voice synthesis. For the OST, lyrics written by a person are often turned into a song with a music generation tool, which is why theme songs sung by a "virtual singer" show up. On the blaiva listings, Suno is the music tool seen most often.

5. Editing: The Stage That Takes the Most Human Effort

Countless short scenes are stitched together, expressions are matched between cuts, and the timing of music and dialogue is adjusted. The same footage can produce completely different emotions depending on the edit, so it's even possible to re-weave deleted scenes into a brand-new piece, like an OST video.

Good to Know as a Viewer

• AI video can occasionally look off in places, such as fingers or text in the background. These are the things creators worry about most, so please be understanding.
• An "made with AI" label tells you how a work was produced; it doesn't mean no one made it. The story and the editing are still the work of people.
• If you love a work, cheer it on in the comments on the original channel. It's a huge motivation for making the next episode.
