This ComfyUI workflow removes persistent watermarks from a video by inpainting over them frame by frame with a LoRA-enhanced diffusion pass. It starts with LoadVideo to ingest your clip and GetVideoComponents to extract frames, dimensions, and timing info. The core processing is handled by two custom nodes (UUIDs 3b019976-c705-40af-8f45-081975d72105 and 83cfc570-fff1-4869-8c43-d39ef189634b), which apply an LTX 2.3 LoRA-guided inpainting step across the sequence to reconstruct clean background detail where the watermark sits. Finally, SaveVideo reassembles the processed frames into a new video file.

Technically, the pipeline performs video-to-video inpainting using a Stable Diffusion-style model augmented by the LTX 2.3 LoRA adapter to bias reconstruction toward plausible content while suppressing the watermark. The custom processing stage maintains per-frame consistency and uses mask-driven edits so only the marked area is regenerated, preserving the rest of the frame. Because the work happens at the frame level and is driven by inpainting, the result avoids typical blur or smudge artifacts of traditional filters and holds up better on semi-transparent, corner logos. It’s a practical, one-click solution for cleaning owned or licensed footage without manual rotoscoping.
