Its main purpose is to take a video or frame-guided video input, preserve the original motion and structure, and use LTX 2.3 with an IC-LoRA Colorizer route to rebuild the clip with stronger color, more coherent lighting, and a more cinematic final look.Unlike a simple video filter or LUT-based color correction workflow, this setup does not only push saturation or contrast on top of the original frames. It uses LTX 2.3 generation, video latent conditioning, image-to-video guidance, IC-LoRA guide injection, prompt-based color direction, tiled decoding, and audio-video latent routing to regenerate the video while keeping the underlying motion consistent. This makes it more useful for AI video restoration, grayscale-to-color tests, stylized recoloring, cinematic color enhancement, and controlled visual remastering.The workflow uses ltx-2.3-22b-dev as the main video model route, combined with ltx-2.3-22b-distilled-lora-384 and LTX-2.3-22b-IC-LoRA-Colorizer-0.9. It also includes LTX video VAE, LTX audio VAE, Gemma / LTX text encoding, LTXVPreprocess, EmptyLTXVLatentVideo, LTXVImgToVideoConditionOnly, LTXAddVideoICLoRAGuide, LTXVConcatAVLatent, LTXVSeparateAVLatent, LTXVCropGuides, SamplerCustomAdvanced, VAEDecodeTiled, and final audio-video export logic.The most important part of this workflow is the IC-LoRA color guide. LTXAddVideoICLoRAGuide injects the guide image or video reference into the latent process, allowing the model to follow the original structure while applying the intended color and visual direction. This is useful when you want the final video to retain the same movement, framing, and scene layout, but gain richer color, stronger material separation, more realistic lighting, or a more stylized cinematic palette.The workflow is also built for manual prompt control. Instead of fully relying on automatic enhancement, the creator can describe the target color style directly: realistic skin tones, warm sunlight, neon cyberpunk lighting, dark fantasy grading, natural outdoor colors, filmic contrast, or any other visual direction. This gives the workflow more creative flexibility than a fixed colorization model.The graph also includes structure-control tools such as DepthCrafter, Canny edge preprocessing, and DW pose preprocessing routes. These help preserve spatial depth, edge structure, and body motion when needed. For video colorization, this matters because color changes should not break the original motion, deform the subject, or destabilize the scene.The workflow keeps an audio-video structure through LTXVEmptyLatentAudio, LTXVConcatAVLatent, LTXVSeparateAVLatent, and LTXVAudioVAEDecode. This means the final output can remain a complete video instead of becoming a silent frame sequence. Tiled VAE decoding is used to make the final video decoding more stable and practical for larger frames.This workflow is ideal for AI video colorization, black-and-white video remastering, stylized recoloring, cinematic grading tests, old-video enhancement, character video cleanup, LTX 2.3 IC-LoRA experiments, RunningHub demos, and Civitai workflow previews.
