@Paul Reznick Ok, it looks like that one frame had a failed tile. As I mentioned in a comment on your video below, this does happen sometimes. I've had it happen to me, normally its not too much of an issue since I render to images and then compile each image into the final video file.

We're working on fixing it though, it will likely be fixed in the beta which we've started coding. Though its going to be a while since all the dev team have day jobs, including me, and we're working on this new design in our spare time as much as we can.

We're also trying to raise funds for the development and running of the website so we can work on this full time. Stay tuned for when we re-launch our campaign. The aim is to get the team working full time on this again so we can deliver crowd render 1.0.0 which will be sooo much better than what we have now :)
