I2V Long Video Extension Master — I2V Infinite Extension

This image-to-video workflow uses an input image and text to generate video, offers extending options, and provides preview images, saved images, and combined video output.

The workflow loads an image, resizes, scales, and batches it, encodes visual and text inputs, runs WanImageToVideo, decodes frames, and combines them into video.

Image inputs can be loaded, resized, scaled, batched, and vision-encoded before video generation.

Text input uses CLIPTextEncode and ttN text; outputs include PreviewImage, SaveImage, and VHS_VideoCombine.
