This ComfyUI workflow expands the boundaries of an existing video clip using LTX-2.3 with a dedicated Video Outpainting IC LoRA. It decodes your source video with VHS_LoadVideo, feeds frames into the core LTX-2.3 generation node (the custom node with ID 2e37ecc9-770a-4ac2-972c-e953901f49d3) where the LoRA guides the model to synthesize plausible content beyond the original edges, and then stitches the processed frames back into a video with VHS_VideoCombine. A MarkdownNote in the graph provides quick, in-context guidance.

Technically, the LoRA biases the base LTX-2.3 video diffusion model toward temporal, context-aware extrapolation. Controls like skip_first_frames and frame_count let you trim a long clip and iterate quickly on a representative segment before running the full range. Outpainting direction and amount are set on the LTX processing node (per-side expansion), while LoRA strength determines how assertively new content is invented versus preserved from the original. The result is a coherent, time-consistent extension of your scene—useful for reframing, adding headroom/side room, or conforming videos to new aspect ratios without obvious borders.
