## Lecture Videos
### New Features
- Users can upload Lecture Videos when creating or updating assistants,
similar to file uploads for File Search and Code Interpreter. _This
feature is not available in the UI with this PR._
- Setting up Lecture Videos assistants now requires a manifest file with
information about comprehension questions. Only single-select multiple
choice questions are currently supported. _Because this change is not
reflected in the UI, Lecture Video assistants are not editable in the
UI._
- Adds database support for (intro and outro) narration files for each
question. _This feature is not available in the UI with this PR._
### Updates & Improvements
- Lecture Videos and the underlying Lecture Video Stored Objects are now
separate in the database, allowing a single LVSO to point to multiple
LVs. This change allows easy copying of lecture-video mode assistants.
### Resolved Issues
- Fixed: When copying a Lecture Video assistant, the Lecture Video
configuration is not copied to the new assistant.
