How severely does this bug affect you? It prevents me from using Vuo at all.
the picking of the files with {getting random file from list} is always a fraction (I din’t measure exactly) late in comparison to the changing of the new position of the video.
We don’t think this is a bug. We couldn’t reproduce it, but this is what we think is happening: It takes a moment for the Play Movie node to initialize the movie, so the position of the image layer might lead the movie output. If you want the movement to synchronize with the output of Play Movie, then you can use a Hold node that is triggered by the the changing timestamp on the video frames output. Let us know if this solves your problem.
