This is a high-quality image-to-video application based on LTX 2.3 multi-image first/last frame guidance + PromptRelay segmented narrative control + three-stage rendering polish + Latent upscaling enhancement. After users upload multiple reference images, the system uses them as keyframes at different stages, injecting them into the video timeline via LTXVAddGuideMulti to maintain stronger directional control from the first frame, through intermediate transition frames, to the final frame. Compared to standard image-to-video, the core advantage of this workflow is: rather than letting a single image improvise freely, it uses multiple keyframes to continuously constrain the video's direction, making character, action, and scene changes much more controllable.
At the same time, this workflow incorporates three-stage sampling, Manual Sigmas, dual LoRA, spatial Latent Upscaler, and tiled decoding to achieve a complete production pipeline from base generation and detail enhancement to final polish. It is especially suitable for: first/last frame transitions, multi-image narrative videos, character styling changes, continuous character action shots, AI short drama storyboarding, e-commerce multi-stage showcases, and high-quality image-to-video content. When using it, it is recommended to focus on three key controls: multiple reference images determine visual changes, PromptRelay determines narrative pacing, and keyframe strength determines transition stability.
