Why aren't my latest videos showing?
Vimeography galleries use a cache layer in order to speed up the gallery load time. Vimeography only checks for new videos according to the settings for each gallery. That way, Vimeography can load the videos quickly based on the ones that existed last time it checked for new videos.
Every check for new videos takes time, so Vimeography will elect to limit those checks. You can modify this setting to adjust the time between checks within your Vimeography gallery editor for an individual gallery.
