app.py 页面没有生成视频的啊？都是图像的

视频生成的在哪啊？能加在app.py 里面吗？感谢
thx

Start with app.py, which the issue identifies as the current image-generation entry point, and inspect how its existing generation flow is exposed. Determine whether video generation is supported by the project and what integration scope is required; the work is done when the intended video-generation behavior is available through app.py.
