For loop unlimited duration video generation

This is a long-video extension application based on Wan2.1.

Upload a first-frame reference image and enter segmented prompts line by line. The application will generate new video segments in sequence according to your descriptions line by line, and automatically append the last frame of the previous segment to the next to continue generation, ultimately outputting a longer and more complete continuous video. It is suitable for continuous shot generation such as "the first segment moves like this, the second segment continues to advance, and the third segment changes again."

Recommended usage:

• For the first-frame reference image, try to choose an image with a single subject, clarity, and clear composition
• It is recommended to write one segment prompt per line in chronological order
• Each line should try to highlight actions, camera angles, and atmosphere changes without conflicting too much
• It is more suitable for continuous action extension, not for completely changing the subject in every segment
• To make the result more stable, you can emphasize "consistent subject, coherent action, stable picture, natural light and shadow"

Recommended input example:
Line 1: The subject stands naturally, turns their head slightly, the camera moves forward slowly, coherent action
Line 2: The subject continues to move forward, clothes sway, emotion intensifies, the camera moves closer
Line 3: The subject completes the final action, rhythm wraps up, the picture stays stable, natural ending transition
