I cannot, and I am sure others here as well, or will not, download from external sites. Use pictures which can be much more insightful for debugging purposes. Plus, they can be hosted on the same server as the nice forum that ANSYS has set up for us.
Have you tried using the TUI to create the video? The cxa animations are under /solve/animate/playback. The other thing is you could just output the individual images and then use any number of other programs, even websites, to stitch them into a video.
The biggest problem I see, is that you only have 30 frames. At a standard ~24 frames per second, there is no wonder your video is only 1 second long. Even if you increased the spacing between frames, there isn’t much there.
