Eli Review is a program that allows students to upload drafts and complete peer reviews online. It has a lot more tools than the Canvas peer review feature. It collects data and saves all the comments so that students can self-reflect as writers during their revision process and self-assess as peer reviewers in order to provide stronger feedback. 

I made a screencast providing an overview of where and how you can create videos in Canvas. This won't be a replacement for other tools like Kaltura Capture and Zoom, but it might provide a nice way to increase a sense of teacher presence for your students.
