ClearText-Video (CTVid) is a large-scale, scene-text-aware benchmark that examines text-centric video understanding under varying quality conditions. It comprises 4,639 real-world egocentric videos, over 550,000 frames, 1.6 million human-verified scene-text annotations, and more than 220,000 spatial/temporal question–answer pairs in Chinese and English. For each high-quality video, CTVid provides matched degraded- and restored-quality variants, enabling studies of Text-Centric Video Restoration and Multi-Quality VideoQA, and revealing that visual enhancement does not always improve textual fidelity or downstream reasoning.

FlexReader is a scene text recognition model that supports multiple decoding strides, allowing a single model to balance accuracy and efficiency across various datasets. It introduces a Sub-string Perception module to extract target substrings from visual features and uses parallel decoding blocks to independently decode each character. During inference, an Adaptive Prefix Decoding strategy selects the optimal stride at each step based on confidence, enabling robust recognition of long, curved, or occluded text while speeding up decoding up to 6× compared to autoregressive methods.

TextVBench is a new benchmark and evaluation framework for assessing how well video generation models render and preserve text. It introduces two tracks—TextVBench‑T2V for prompt‑specified text creation and maintenance, and TextVBench‑Ref2V for preserving text from reference images—using a multi‑target, multi‑instance spatiotemporal correspondence approach. The framework employs target‑conditioned candidate selection, supports multiple OCR regions per target, and separates spatial and temporal fidelity, summarizing results with a length‑weighted harmonic score and detailed diagnostics.
