Video Extension 3.0 | OmniNFT Relay Distillation 1.1 | Vertical Screen Expansion

This is a vertical-to-horizontal video expansion application based on LTX2.3 Dev-Dare merged distilled 1.1 + IC Outpaint LoRA + video frame preprocessing + Resize / Pad canvas expansion + LTXAddVideoICLoRAGuide original video reference guidance + LTX video sampling + tiled decoding output. After a user uploads a vertical video, the system reads the original video frames, expands the footage to a wider landscape aspect ratio, and uses IC Outpaint LoRA to generate the missing left and right areas, naturally converting vertical footage into a landscape video as much as possible.

The core advantage of this workflow is: It is neither simple stretching nor cropping, but generative inpainting. It is suitable for expanding vertical talking-head videos, vertical character videos, smartphone-shot footage, short video clips, live stream cuts, AI digital human videos, vertical MVs, and vertical product videos into landscape 16:9. Compared to regular image expansion, it processes video frames, requiring the preservation of the main character, background lighting and shadows, camera motion, and inter-frame consistency as much as possible. Although the current file title contains OmniNFT / Relay, the actual main pipeline does not show the corresponding nodes. Therefore, it is recommended to feature IC Outpaint Video Expansion primarily upon release, rather than OmniNFT / Relay, unless the nodes are subsequently added and tested. When using, it is recommended to focus on controlling four items: Input video determines the original subject, output width and height determine the expansion ratio, expansion prompts determine the completion content, and the dark scene correction switch determines whether dark videos can stably expand their edges.
