I was looking for that landslide effect (as seen even in Sora and Kling) where land seems moving very disproportionally to everything else. It makes me motion sick. I have not seen those Sora demo videos a second time for that reason.

These are smooth, consistent, no landslide (except sloth floating in water, the stones on right are moving at much higher rate than the dock coming closer), no things appearing out of nowhere. Editing seems not as high quality (the candle to bubble example).

To me, these didn't induce nausea while being very high quality makes it best among current video generators.
