I mean still do the long exposure as you're doing for your stills. And use say, 25 long exposure photos per second for the video. But make the patterns animated, so for example with https://www.stavros.io/posts/behold-ledonardo/maria-small.jpg https://www.stavros.io/posts/behold-ledonardo/maria-small.jp... you could have the light appear to rotate around the lady. I imagine it'd be extremely slow work, creating enough photos though!
