If you want students to watch and comment on each other's films, the easiest way is to use discussion forums.

We suggest that you recommend that students use the Studio icon in the discussion forum to either upload an existing video or create a new video directly into the rich content editor (RCE) window in the forum reply function:

Upload or record video from Studio in the forum

Video showing how students (and teachers) record directly into the RCE

In this video (5:14min) Carina Bois shows you how to record a video directly into the RCE. She also shows you how to publish the closed captions for the video in step 2.

Video via discussion forum

Create a new discussion forum
Write an instruction stating that the students must report by creating and uploading a video. Point out that they should click the blue Studio icon in the content editor.
If it is a compulsory assignment and the students are to be assessed, click in Graded. In this case, the discussion automatically becomes an assignment that appears in the gradebook. You can also comment and grade the task in Speedgrader.

Speedgrader feedback

Students can upload an existing video, taken on their mobile phone, or click Create when they open the Studio Library, to record a video directly into the page. This student has uploaded a video recorded in Zoom using an avatar - maybe they were having a bad hair day? The teacher can grade and give feedback in Speedgrader.
