No video loading I get the message "Total generated frames: 0, Video length: 0.00 seconds (FPS-30). The video is being extended now ..."

As the title says, I try to generate a video, I get latent images but nothing in the video preview window and I get the Total generated frames: 0, Video length: 0.00 seconds (FPS-30). The video is being extended now ...message above the loading bar. When everything is done there is no video.


Any advice?

Start by reproducing the reported video generation failure and inspect the video preview window, loading bar, and generated-frame counters. The issue does not name a source file, test, or environment, so first identify the entry point responsible for turning latent images into the preview video. Done means generation produces a video with nonzero frames and duration.
