Microdrama makers say the first 30 seconds decide a vertical series, not the shoot

Two microdrama studio heads told the Taiwan Creative Content Fest in Taipei on Sunday what keeps viewers in a vertical feed. Sawamura Naomichi, CEO of emole, which runs Japan's Bump app, said Bump tracks drop-off in the first 30 seconds of episode 1. İlkin Kavukcu of Turkey's İki Dakika said a hook needs emotional recognition, not a twist, Variety reported.

For AI creators the useful part is what nobody on stage talked about: production cost. Cheap production does not buy attention. The first episode, and its first 30 seconds, decide whether a series lives, so the hook and a villain the audience wants punished are worth more than any saving on the shoot. Neither speaker mentioned AI and both studios shoot live action, so this is a playbook AI makers inherit rather than one they wrote. The coverage also missed the money: Bump is putting up to 5 million yen (about $32,000) into new original series right now.

What holds the feed

The session, The Attention War, was moderated by Yvonne Chen of the Taiwanese short-drama producer CHOCO Media. Kavukcu, a former TV journalist whose studio has posted vertical series to TikTok, Instagram and YouTube since October 2025, said her studio looks for moments when viewers see something of their own lives and stop scrolling. Sharing, in her account, is the sign a series has connected, and the studio builds long-running characters instead of stacking one-off plot twists.

Sawamura, who launched Bump in December 2022, named the four genres that work in Japan: female rivalry, hidden identity, infidelity and revenge, and lightly suggestive dramas aimed at men. Hidden-identity stories travel furthest, he said, because the series can keep delaying the reveal and the confrontation. His villain rule is simple: make the villain infuriating enough and viewers stay to see them punished. He named the same first three genres in a TV Guide interview a year ago, so this is a settled view.

Bump's two numbers

The 30-second check is the line that will travel, but it is only the top of Bump's funnel. Sawamura said Bump also watches whether viewers move on to episode 2, and in a case study by the analytics firm Repro its product team names a different top metric: the 7-day completion rate, the share of new users who finish a whole series within a week.

The production numbers show where the time goes. Sawamura said Bump spends about two months developing a project before the script is approved, then roughly 30 days on filming and post. A 25-episode series running about 45 minutes in total is shot in four days, and Bump has 20 to 30 projects in production at once. Development takes twice as long as making the thing: the script is the bottleneck.

Brands inside the story

Kavukcu described a model in which brands help build the story world and its economics, not just place a product in an episode. She said İki Dakika has worked with around 30 brands and is developing Italian co-productions. Asked whether microdrama IP can move into other formats, she answered: "We are already doing this. We can shoot in both vertical and horizontal formats, as long as we have a long enough production schedule. In Turkey, companies including Disney are also interested in trying this." We found no statement from Disney, so that part is her word only. Bump sells the same idea in Japan: on Friday 30 October the ad agency Dentsu Digital and emole launched a short-drama ad product for TikTok.

The money on the table

The detail missing from the session report is Bump's open checkbook. Its BUMP Creative Challenge, opened on Thursday 24 September, offers up to 5 million yen per original series of 25 or more episodes, covering at most half of a budget of up to 10 million yen (about $64,000), in exchange for exclusivity on Bump. Entries closed on Sunday 1 November and results are due Monday 30 November. The rules say nothing about AI. Bump's own announcement puts July revenue at about nine times a year earlier, with payouts to producers and creators up about sixfold.

Treat Bump's scale claim with care. Session materials cite more than 4 million downloads and 7 billion social media views, but the views are plays of promotional clips on Bump's own social accounts, not plays inside the app, and its August release said 6.5 billion.

What it means for AI creators

AI makers can produce a season faster than a live-action crew shoots one, which makes these craft points worth more, not less.

• Write the first 30 seconds as its own deliverable: the protagonist's stakes, the conflict and the payoff to come.
• Measure the finish as well as the start, because a hook that wins the click and loses the series is a trailer, not a show.
• Spend your saved shoot time on development, since a studio that can film 25 episodes in four days still gives the script two months.
• Hidden identity travels best, and it rewards characters who stay consistent across many episodes, which is where AI series still slip.
• Bump funds originals in the open and its current rules do not exclude AI, so it is worth reading the terms for the next round.

Our take: the studios that hold a vertical feed win on writing and on knowing where viewers leave, and AI changes neither. Makers who spend the savings on episode 1 can beat live action on its own terms.
