Moodle 3.5 has introduced the ability to record audio/video directly into the Atto editor via the RecordRTC icons/buttons.
However, as a teacher, when entering feedback comments in the Assignment activity, there are no RecordRTC icons in the Atto editor.
- Add an assignment activity to a course, configure with Feedback comments enabled
- Log in as a student and submit an assignment
- Log in as a teacher
- Go to the Assignment activity and click on [Grade] to grade the student
As a consequence, it is not possible to record video/audio directly into the Atto editor for a Teacher giving Feedback comments in an Assignment.
https://tracker.moodle.org/browse/MDL-60848 states that this functionality should "crucially, add the capability for this to be used in the HTML feedback part of the assignment and gradebook so that multi-media feedback can be given"
