Is it possible for a teacher to leave comments on an Arc video to share with students but not allow student commenting? When I have uploaded a video and added comments the only way students could see my comments was if I enabled commenting. It would be nice to add a video and have it part of an assignment without an open discussion.
That does not appear to be possible. You could of course add text to the item where you embed it but you can not link a comment to a specific spot in the video.
