As a system administrator, I can recompute the renditions of the videos within a folderish document and its children

Behavior is similar as [REINDEX-FOLDER]
With the following differences:

Tab name: "Folder"

"Generate the video renditions of a document and all of its children"

Parameters:

• Document ID or path
  • Placeholder: Document ID or path
• Conversion names
  • Helper text: Provide a list of conversion names to generate, or leave this field empty to regenerate them all. Separate each entry by a comma.
• Information to recompute
  • Recompute missing information only (default) / Recompute all video information (exposed as a dropdown)
