Looking for locally hosted tool to create English subtitles from videos

A user is seeking a locally hosted, self-contained app to generate English subtitles (in .srt or .ass format) from video files. They consider Qwen-ASR and Whisper as strong options but report poor subtitle timing in ComfyUI implementations and unreliable performance with older models like those in storytoolkitAI. They ask for recommendations that work well on Windows and can handle multiple languages.

LegalHalluLens: Auditing Hallucinations in Legal AI

LegalHalluLens introduces a framework to audit AI hallucinations in legal contexts by analyzing typed hallucination profiles across four claim categories. It reveals a 38-40 point gap between obligation/numeric and temporal claims, and shows two systems with identical 52% hallucination rates can have opposite risk directions. The framework uses a Risk Direction Index and calibrated debate pipelines to reduce fabricated detections by 45%, offering actionable diagnostics for trustworthy legal AI deployment.

Recursive Masked Diffusion Models Introduce New Scaling Axis

Recursive Masked Diffusion Models (R-MDMs) introduce recursive depth as a third scaling axis by reapplying a denoising transformer within each diffusion step. This recursion enables iterative output refinement without increasing parameter count, achieving performance comparable to non-recursive models with up to L times more parameters, where L is the number of iterations. R-MDMs also reduce inference compute by partially replacing denoising steps with recursive refinement.

Baseline Evaluation of Open-Source LLMs for Multi-Label ATT&CK Classification

A ground-truth dataset of 2,076 human-annotated sentences from 83 complex CTI reports was constructed and mapped to 114 ATT&CK techniques with \k{appa} = 0.68 inter-annotator agreement. Seven open-source LLMs ranging from 8B to 236B parameters were evaluated, achieving a maximum micro-averaged F1 score of 0.22. Parameter size showed a statistically significant positive correlation with F1 score, while prompt strategy and temperature did not yield significant improvements, indicating current open-source LLMs are insufficient for production-grade ATT&CK classification.
