RunningHub has many workflows related to generating the first and last frames of videos 

and consistent last frames. However, if you want to make a long, coherent video,

 generating the last frames one by one is still quite painful and time-consuming. 

You will also find that you need to break down the pictures frame by frame according to 

the plot you set, because when you generate the next frame, it no longer knows what the

 previous frame was about. That's why you need this workflow to help you generate 

storyboards with one click!
