## Content

**Seedance 2.0 (ByteDance, February 2026) + Wan 2.7 (deployed on Mootion, April 15, 2026):**

Key capabilities achieved as of April 2026:
- **Character consistency across camera angles**: no facial drift, characters maintain exact physical traits from any camera angle across shots
- **90-second video clips** with native audio synchronization and cross-scene continuity
- **Phoneme-level lip-sync** across 8+ languages
- **4K resolution** output
- **"AI morphing" problem solved**: the temporal inconsistency that made AI video unsuitable for narrative content (characters changing appearance between shots) is now resolved at the model level

Comparison with competitors: Seedance 2.0 outperforms Sora on character consistency as its clearest differentiator. Baseline character consistency higher than Sora's.

Production cost data (2026):
- 3-minute AI narrative short: $75-175 (vs. $5,000-30,000 traditional) — 97-99% cost reduction confirmed
- Premium AI tools cost 90-99% less than traditional production for comparable short-form outputs

Remaining limitations:
- Micro-expressions and performance nuance: human actor micro-movements cannot yet be replicated
- Long-form coherence: 90-second is current clip limit; feature-length narrative still requires human direction and stitching
- Controllability: fine-grained creative direction beyond prompts is limited

**Tencent CEO at Hainan Island Film Festival (late 2025):** 10-30% of long-form film and animation "dominated by or deeply involving AI" within 2 years. First premium Chinese AI-generated long drama expected H2 2026.

AI filmmaking production cost breakdown (MindStudio, 2026):
- 3-minute narrative short, AI-produced: $75-175
- Same runtime, traditional independent: $5,000-30,000
- For equivalent longer runtime: even premium AI tools are 90-99% cheaper

## Agent Notes

**Why this matters:** Character consistency across shots was the specific technical barrier preventing AI tools from producing coherent serialized narrative content (animated shows, webtoons, episodic storytelling). This was one of the last major technical gaps between AI-produced short-form content and AI-produced serial narrative content. Its resolution in Q1 2026 means the production cost collapse is no longer blocked by this technical limitation for SHORT-form narrative. The remaining barrier (long-form coherence beyond 90 seconds) is now the primary constraint.

**What surprised me:** The "AI morphing" problem being solved isn't a theoretical advance — it's a deployed product feature in Seedance 2.0. This means creators are using character-consistent AI video production TODAY, not in 2-3 years. The Lil Pudgys animated series (TheSoul Publishing, launched April 24, 2026) may be using these tools — TheSoul is known for algorithmically-optimized, cost-efficient production.

**What I expected but didn't find:** More precise data on how the 90-second clip limit scales for long-form production — whether multiple clips can be stitched into coherent long-form content or whether coherence degrades across cuts. The "narrative coherence beyond 90 seconds" problem may be solvable through careful editing + consistent character seeds, but I didn't find specific production data.

**KB connections:**
- [[GenAI is simultaneously sustaining and disruptive depending on whether users pursue progressive syntheticization or progressive control]] — Seedance 2.0 is clearly a "progressive control" tool (start fully synthetic, add human direction) rather than "progressive syntheticization" (make existing workflows cheaper). This is the disruptive path.
- [[non-ATL production costs will converge with the cost of compute as AI replaces labor across the production chain]] — confirmed: 97-99% cost reduction for short-form narrative production in 2026. Long-form (ATL quality) remains the remaining gap.
- [[five factors determine the speed and extent of disruption including quality definition change and ease of incumbent replication]] — quality definition change: from "human performance fidelity" to "character consistency + narrative coherence." The incumbents (studios) cannot easily replicate the independent disruptive path because they're optimizing existing workflows (progressive syntheticization), not starting from fully synthetic.

**Extraction hints:**
1. Update to [[non-ATL production costs will converge with the cost of compute as AI replaces labor across the production chain]]: add 2026 data showing short-form narrative is at 97-99% cost reduction with temporal consistency solved; long-form remains the outstanding technical threshold (~90-second clip limit).
2. New claim candidate: "AI-generated serialized narrative content is viable in 2026 for short-form formats because the temporal consistency problem has been solved, shifting the remaining production barrier to long-form coherence rather than character consistency." This is a precise calibration of the production cost collapse timeline.
3. The Tencent prediction (10-30% of long-form film/animation AI-dominated within 2 years) is a major industry player's forward-looking estimate that should be archived as a prediction to track.

**Context:** Seedance 2.0 was developed by ByteDance (TikTok's parent). The deployment on Mootion represents a specific product update that makes the character consistency capabilities accessible to independent creators. ByteDance's position in AI video production is significant — they have incentives to democratize AI video creation (more content for TikTok) while also holding unique data advantages in short-form video performance.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[non-ATL production costs will converge with the cost of compute as AI replaces labor across the production chain]] — this source provides the most specific 2026 calibration of WHERE on the cost collapse curve we are.
WHY ARCHIVED: The temporal consistency breakthrough (character consistency across shots) is the specific technical milestone that enables AI-produced serialized narrative content, removing the primary barrier to narrative production at near-zero cost.
EXTRACTION HINT: Update the non-ATL production costs claim with 2026 production cost data ($75-175 for 3-minute short) and temporal consistency achievement. Propose new claim on the AI serialized content viability threshold.
