Katechon ArcOur feature, shot by shot
The Fall of Kalak is a 42-minute, 9-episode dark-fantasy feature with 13 characters and 21 locations, made in Arc. We rendered episode 1 on Seedance 2.0 and the rest on Seedance 2.0 Mini, all at 720p. All 427 shots rendered in one day.
| Scope | Model | Clips | Spend | Per clip |
|---|---|---|---|---|
| Episode 1 | Seedance 2.0 720p | 53 | $61 | $1.15 |
| Episodes 2–9 | Seedance 2.0 Mini 720p | 374 | $52 | $0.14 |
Moving episodes 2–9 to Mini cut their video cost by roughly a factor of eight. At Mini's per-clip cost, all 427 shots would have come to about $59. The Wolf Mother, a 47-minute film, used 431 successful generations on Seedance 2.0 Mini.

What else a feature needs
- Narration or voice where clip audio is not enough. We used ElevenLabs narration on The Wolf Mother.
- A score and sound pass, chapter cards and captions, usually in an editor outside the generator.
- Optional upscaling: Topaz upscaling to 4K cost us about $0.07 per output second, roughly $190 for 45 minutes.
- Time. A feature is hundreds of shots; plan for a few days of review even when rendering takes one.
In Arc credits
In Arc, 45 minutes on Seedance 2.0 Mini at 720p in six-second clips is about 29,395 credits, and about 232,581 on Seedance 2.0. Organization covers the Mini version in a month.
Where Katechon Arc fits
Arc handles a feature as a set of episodes or chapters that share one cast and one set of locations, which is how we made our own 40-plus-minute films.
Arc renders shots and assembles a cut; for a theatrical-grade finish you will still edit, score and grade in a desktop editor.
