Its main purpose is to take a source video or control video, define the region that needs to be modified, and regenerate that part through LTX 2.3 while preserving the original timing, motion rhythm, audio, frame rate, and overall scene structure as much as possible.Unlike a simple blur, crop, overlay, or single-frame repair method, this workflow is built as a video-level local reconstruction pipeline. The goal is not to destroy the whole shot and regenerate everything from scratch. Instead, the workflow keeps the source material as the structural guide, uses masks to define the editable area, and lets LTX 2.3 repaint only the required region while maintaining temporal continuity across frames. This makes it useful for authorized video cleanup, local object replacement, detail correction, character-area adjustment, controlled visual repair, and reference-guided video transformation.The workflow uses LTX 2.3 as the main video generation backbone, with LTX video VAE, LTX audio VAE, LTXVAudioVAEEncode, LTXVConditioning, LTXVCropGuides, LTXVConcatAVLatent, LTXVSeparateAVLatent, SamplerCustomAdvanced, tiled VAE decoding, and final audio-video export logic. It also uses SetNode / GetNode routing for shared components such as FPS, total frames, duration, base model, video VAE, audio VAE, CLIP, control video, latent conditioning, masks, result frames, and audio. This modular structure makes the workflow easier to adapt to different videos and repeated local redraw tasks.A key part of the workflow is the mask and guide system. The source video or control video is used to determine the frame size, frame count, and timing. SolidMask and related mask-routing logic define the region that should be affected. The workflow then crops and manages guide conditioning so that the model can focus on the intended local area instead of drifting across the full frame. This is important for video inpainting because uncontrolled redraw can easily change the face, clothing, background, camera angle, lighting, or motion outside the edited area.The audio route is also preserved. The workflow includes audio loading / recording, audio VAE encoding, audio latent handling, and final audio routing. This means the final output can remain a complete video instead of becoming a silent visual-only repair. For creators working on AI video demonstrations, talking characters, short dramas, product clips, or social media edits, keeping the audio-video structure intact is a major practical advantage.The workflow also uses multiple generation and refinement stages. The first stage builds the repaired latent video under the source guide and mask constraints. Later stages can continue refining the result, decode with tiled VAE logic, and prepare the final output. This makes the workflow more suitable for real production testing than a small single-pass experiment.This workflow is ideal for creators who want to repair or modify a specific video region while keeping the rest of the shot stable. It can be used for LTX 2.3 local redraw tests, reference-guided video inpainting, AI video cleanup, controlled character-region edits, object-region repair, and Civitai / RunningHub workflow demonstrations.
