PersonaShot (arXiv 2608.16717v1, 17 Aug 2026) has about 1,000 multi-shot segments and 16 metrics; Identity Consistency (ID) is tracked-character cross-shot embedding similarity. In its Table 2 (shot-level prompts) ID is Seedance 0.673, HoloCine 0.582, LTX-2.3 0.572, MultiShotMaster 0.557, EchoShot 0.463; under global prompts ID is LTX-2.3 0.697, VGoT 0.683, Seedance 0.642. The headline finding is that visual fidelity does not predict continuity: ShotStream has VF 0.994 but aggregate 0.601, and the authors say physical-state resets and abrupt affective shifts persist even in good-looking videos. Three specialist evaluators (distilled from Qwen3.5-397B into Qwen3.5-4B LoRA) correlate 0.69-0.75 with human MOS. No code or data link was found.
