Thanks, everyone. Yes, I guess  you need dvix installed to view the video. Thank you for bringing this up. I've taken out the lens flare and this seems to make no difference. I notice it takes about two to three times longer to load this particular Vue file into vue. I'm going to try to render some other things to see if they show the same problem.  Apart from the balloons, the only other thing animated is "animated materials-foam".
