  Content retargeting is crucial for social media creators. Once great content
is created, it is important to reach as broad an audience as possible. This is
particularly important in journalism where younger audiences are shifting away
from print and towards short-video platforms. Many newspapers already create
rich graphics for the web that they want to be able to reuse for social media.
One example is scrollytelling sequences or "scrollies" -- immersive articles
with graphics like animation, charts, and 3D visualizations that appear as a
user scrolls. We present a system that helps transform scrollies into social
media videos. By using the scriptwriting concept of narrative beats to extract
fundamental storytelling units, we can create videos that are more aligned with
narration, and allow for better pacing and stylistic changes. Narrative beats
are thus an important primitive to retargeting content that matches the style
of a new medium while maintaining the cohesiveness of the original content.
