I isolated the error to the following in display_video_snippet.html

 {% if video.project %}
          |<a href="{% url 'website:project' video.project.short_name %}">{{ video.project.name }}</a>
      {% endif %}

At some point, we allowed videos to be associated with multiple videos, so video.project no longer exists. In fact, it's commented out in the Video model:

class Video(models.Model):
    video_url = models.URLField(blank=True, null=True)
    video_preview_url = models.URLField(blank=True, null=True)
    title = models.CharField(max_length=255)
    caption = models.CharField(max_length=255, blank=True, null=True)
    date = models.DateField(null=True)

    projects = models.ManyToManyField('Project', blank=True, null=True, related_name='videos')
    #project = models.ForeignKey('Project', blank=True, null=True, on_delete=models.SET_NULL)

So, the solution is something like we have in display_pub_snippet:

{% for project in video.projects.all %}
        {% if forloop.first and video.projects.all|length > 0 %}| {% endif %}
        {% if project.can_show_online %}
            <a href="{% url 'website:project' project.short_name %}">{{ project.name }}</a>{% if not forloop.last %} • {% endif %}
        {% endif %}
      {% endfor %}
