AI short drama brief, Nov 12: Seedance 2.5 4K reaches Krea and Picsart, Luma halves video-to-video rates, a one-person AI series passes 100 million views

Three lines for today

1. Models: ByteDance's Seedance 2.5 4K has moved from enterprise trials to consumer platforms, with Krea and Picsart announcing it on November 11; the pitch is to test shots as 480p drafts and render only the keepers in 4K. BytePlus still has not published an official price.

2. Prices: Luma cut its marketplace video-to-video rates by about half and now bills generated plus reference seconds; at its Plus plan rate, Seedance 2.5 text-to-video at 720p works out to about $0.23 a second, roughly a fifth below Runway's reseller price.

3. Production: China Daily reported on November 11 that a former game artist made the 21-episode AI sci-fi series Guixu alone, passing 100 million views on more than 200,000 yuan of compute, and that a six-person remote team's Armed into the Song Dynasty has topped 12 billion views over about 1,000 episodes without paid promotion.

Models and pricing

Seedance 2.5 4K opens up to ordinary creators. BytePlus's October 27 blog post framed it as an enterprise model with 4K output, 10-bit color, a 480p draft mode and sharper fine text from reference material such as posters and packaging, on trial with selected film and post-production companies. On November 11 Krea and Picsart announced it on their official X accounts; Krea's sample clip includes a 3840×2160 version, and Picsart lists scenes of up to 30 seconds from one prompt, character consistency across up to 50 references and dialogue in 20 languages. BytePlus has published no general-availability notice or price, each platform bills differently, and we have not reconciled the 20-language claim with BytePlus's documentation.

Luma roughly halves video-to-video rates. Luma's pricing page, read November 12, now bills video-to-video per second of generated plus reference video: Seedance 2.0 at 720p is 32 credits a second, MiniMax H3 at 768p 28 and Kling 4.0 Omni at 1080p 47; SlopTV, citing PricingSaaS's November 2 capture, puts the old rates at 64, 56 and 98. The page also adds Kling 4.0 Flash and Flash Omni at 32 credits a second for 720p. The $30 Plus plan buys 10,000 credits, about $0.003 each, so Seedance 2.5 text-to-video at 720p (78 credits) is about $0.23 a second, its 480p draft (36) about $0.11, and Kling 4.0 at 720p (53) about $0.16. The longer your reference clip, the more the new billing basis eats the cut.

No official change at the other sources we checked: Runway's developer price list and Google's Omni 1.2 Flash (see our November 10 and 11 briefs).

Platforms and channels

European public broadcasters are making their own vertical dramas. Bavarian broadcaster BR said on November 11 that it has wrapped STAY, its first microdrama: 40 episodes of 60 to 90 seconds, shot entirely in 9:16, releasing in spring 2027 on a Bayern 3 channel on Instagram and TikTok, produced by WennDann Shorts. With RTL+ and TF1+ also moving, European broadcasters are a new kind of buyer and partner, though what they want is local live action.

A checkable revenue number for Indian subscription microdrama. Vertical Observer, citing Entrackr's November 10 report, says QuickTV, the microdrama app of ShareChat parent Mohalla Tech, brought in Rs 293 crore of subscription revenue in FY26, while the company's business development spending rose 8.7 times to Rs 335 crore and it spent Rs 1.75 for each rupee of operating revenue. This is a press account of annual results; subscription revenue is recognized over the subscription period.

Charts and hooks

Dramagoing reported on November 11 that Chinese companies are the main distributors of 82 of October's top 100 overseas short dramas, with NetShort holding 63 places and DramaBox 9, and that from January to September DramaBox earned $302 million overseas, ReelShort $265 million and NetShort $205 million. The chart is not named, so treat these as secondhand. For the weekly chart, see our November 10 brief.

Methods and workflow

AI series made by one person and by six. China Daily reports that Guixu runs 21 episodes of about eight minutes, with its creator handling worldbuilding, script, image generation, editing and score alone; a few seconds of cinematic footage often took a prompt of over 1,000 characters, and raw compute cost more than 200,000 yuan. Armed into the Song Dynasty was made by six people who have never met, working remotely, and had passed 12 billion views over 10 seasons and about 1,000 episodes by November 7; after it took off, the team cut output to work on the story. These are figures as reported.

Using a security-camera format to stop large scenes jumping in space. On November 10 X user @liyue_ai published a 30-second Seedance 2.5 prompt that frames the whole piece as fixed black-and-white surveillance footage: no camera movement and no cuts within each segment, one switch at 12 seconds, a fixed screen layout (land on the left 40%, river on the right 60%), a fixed direction of attack, per-second timestamps and a list of banned moves (close-ups, slow motion, aerials, fast cutting). Reproducibility: shown by the author only; we did not generate a test. The trade is spatial stability for camera movement.

What it means today

1. If you are choosing a video model: run the same scene as 480p drafts on Krea or Picsart and render only the chosen shots in 4K, and log what each platform actually charges, since there is no official price to budget against yet.

2. If you do retakes or restyles: video-to-video is now about half price on Luma, and trimming the reference clip before sending it is how you keep most of the saving.

3. If you are writing fights or crowd scenes: draft the blocking with a fixed camera, a screen layout, a direction rule and a banned-moves list, then add camera movement once the geography holds.

What remains unclear

BytePlus has not published Seedance 2.5 4K's general pricing, duration limits or quotas, and platform claims such as "highest quality" and "20 languages" are unverified; Luma's earlier rates come from a third-party capture; the QuickTV and overseas top-100 figures are press accounts; the Guixu and Song Dynasty figures are as reported by the creators or the paper. We generated no test footage with any model and contacted none of the parties.
