+**LTX2.3-ICEdit-Insight** is a task-aware video restoration and editing model family developed by **JoyFox Lab**, built on top of the **LTX-2.3 DiT-based audio-video foundation model**.
+This release focuses on four practical video editing directions:
+- **Video Restoration**: degradation recovery, compression cleanup, blur and noise reduction, and damaged detail restoration.
+- **Video HD Enhancement**: super-resolution, detail reconstruction, texture sharpening, and perceptual quality improvement.
+- **Watermark Removal**: logo cleanup, semi-transparent overlay removal, and occlusion-aware background reconstruction.
+- **Subtitle Removal**: hard subtitle removal, caption cleanup, text overlay removal, and temporally stable inpainting.
+Unlike conventional frame-level enhancement pipelines, this model family operates as a **generative video restoration system** in latent video space. It is designed to preserve global structure, camera motion, object identity, and temporal consistency while reconstructing missing or degraded visual content.

+## 📄 Paper
+- **Title**: *LTX-Insight: Unified Video Restoration and Semantic Editing via Task-Aware Adaptation and Temporal Consistency*
+- **Authors**: Fan Tang, Siyuan Li
+- **Venue**: Research Square
+- **Posted date**: May 25, 2026
+- **DOI**: [`10.21203/rs.3.rs-9775063/v1`](https://doi.org/10.21203/rs.3.rs-9775063/v1)
+- **Paper URL**: https://www.researchsquare.com/article/rs-9775063/v1
+This model release corresponds to the paper's unified video post-processing framework built around three high-level settings: video super-resolution/enhancement, occlusion removal and repair, and instruction-driven semantic editing.
+In the currently released inference package, those ideas are exposed through four practical routes:
+- **Video Restoration**
+- **Video HD Enhancement**
+- **Watermark Removal**
+- **Subtitle Removal**
+The paper introduces three core components:
+- **TADA (Task-Aware Decoupled Adapter)** for separating structure restoration from texture/semantic editing under a shared backbone.
+- **FGLC (Flow-Guided Latent Consistency)** for explicit temporal consistency modeling in latent space using optical-flow alignment and cross-frame attention bias.
+- **PMTR (Progressive Multi-Task Routing)** for more stable joint multi-task training through curriculum scheduling and collaborative routing.

+## ✨ Key Improvements
+### Task-Aware IC-Edit Framework
+We introduce a task-aware IC-Edit training framework for LTX-2.3, where each restoration direction is optimized with dedicated instruction conditioning and task-specific IC-LoRA adapters.
+The model is trained not only to improve visual quality, but also to understand the editing goal behind different restoration tasks, including watermark removal, subtitle cleanup, damaged region recovery, and high-definition enhancement.
+### LTX-2.3 DiT Backbone Adaptation
+The model family is built on the LTX-2.3 foundation architecture, a diffusion-transformer video model designed for high-fidelity image-to-video and video generation workflows.
+Our adaptation targets video restoration by improving:
+- latent-space editability
+- instruction-following behavior
+- frame-to-frame stability
+- high-frequency detail recovery
+- local reconstruction around degraded or occluded regions
+### Spatiotemporal Consistency Optimization
+Video restoration requires more than strong single-frame quality. We optimize temporal consistency so that restored areas remain stable across adjacent frames.
+This reduces common artifacts such as:
+- flickering textures
+- unstable reconstructed backgrounds
+- inconsistent watermark removal
+- subtitle ghosting
+- frame-wise color shift
+- detail popping during motion
+### Degradation-Aware Training Curriculum
+The training curriculum covers realistic video defects including:
+- compression artifacts
+- motion blur
+- sensor noise
+- low-bitrate video
+- text overlays
+- hard subtitles
+- semi-transparent watermarks
+- platform logos
+- local occlusions
+- low-resolution inputs
+This improves generalization across short videos, social-media clips, mobile footage, downloaded videos, and compressed production material.
+### Occlusion-Aware Reconstruction
+For watermark and subtitle removal, the model is optimized to reconstruct the hidden visual content behind occluded regions.
+Instead of smearing or blurring the target area, it uses surrounding spatial context and temporal cues to infer plausible background structure, object boundaries, lighting, and texture continuity.
+### Frequency-Enhanced HD Restoration
+For HD enhancement, the model improves perceptual sharpness and fine visual detail through frequency-aware restoration training.
+This is especially helpful for recovering:
+- hair strands
+- fabric texture
+- skin detail
+- product edges
+- background patterns
+- typography-like fine structures
+- natural image clarity
+## 🧠 Inference Notes
+- Single-stage inference is recommended for most editing tasks.
+- Two-stage refinement can improve visual polish but may weaken task-specific LoRA constraints.
+- Watermark and subtitle removal perform best when the occlusion area is stable and not excessively large.
+- HD enhancement quality depends on input resolution, motion complexity, and compression level.
+- Higher output resolution improves detail but requires more VRAM.
+- For strong-motion videos, conservative denoising settings are recommended to preserve temporal structure.
+- Frame count should follow the `8k + 1` rule.
+- Output height and width should be multiples of `32` in single-stage inference.
