Adding video to the Library and assigning them
You can add video to your Perusall course alongside your reading assignments. To add a video, select Library > Add content > Video and then enter a URL based on where the video is stored.
Enter the URL of the page in YouTube that has the video you want to add (e.g., https://www.youtube.com/watch?v=WTQJp9wllow). The video must be publicly accessible (Perusall won't be able to import private videos).
Accessibility notes: Perusall will show captions on YouTube videos when available. YouTube only provides captions to Perusall when they are uploaded by the video author (i.e., YouTube's automatically-generated captions won't show up in the Perusall player). Due to a technical limitation, captions will always be shown within the Perusall player when available. To access the original YouTube video and any associated transcript or additional captions that aren't accessible within Perusall, click "View original web page" in the Perusall Library entry for that video.
Enter the URL of the page in Vimeo that has the video you want to add (e.g., https://vimeo.com/98256980).
In the file list in Google Drive, right-click on the video and click Get shareable link; then paste that URL into Perusall. Alternatively: open up the video, click the three dots button in the upper-right corner, click Share, click Copy link at the bottom, then paste the link into Perusall. The link must be publicly accessible (Perusall won't be able to import files that are only shared privately).
(Note: We recommend only using Google Drive for small video files. Google Drive places bandwidth restrictions on how much can be streamed from your account. This is not a limit on our side--The limit platforms like google drive is not just on how much storage space is used, but how much is transferred/downloaded by students-- example: when a student watches the video the video is downloaded to their computer--so if a lot of students watch the video over a short period of time and the video file is large then you could hit the bandwidth limit. Consider using YouTube or Vimeo for larger files.)
Find the file in Dropbox, then click the Share button. In the resulting dialog: click Create link, click Copy link, then paste the link into Perusall.
(Note: We recommend only using Dropbox for small video files. Dropbox places bandwidth restrictions on how much can be streamed from your account. If you exceed 20 GB per day in bandwidth across all shared files on your Dropbox account -- 200 GB per day for Plus, Family, Professional, and Business accounts -- then none of your shared links will work for at least 24 hours, including any Dropbox videos in your Perusall course. This is not a limit on our side--The limit platforms like Dropbox is not just on how much storage space is used, but how much is transferred/downloaded by students-- example: when a student watches the video the video is downloaded to their computer--so if a lot of students watch the video over a short period of time and the video file is large then you could hit the bandwidth limit. Consider using YouTube or Vimeo for larger files.)
You will need to locate the direct file for the video. See below for instructions:
- Open the inspect tab (developer tools), go to the network tab, and filter on only XHR;
- Click to a random part in the video and you should see a few new entries. Mouse over each looking for one starting with
https://cfvod.kaltura.com/scf/hls/p/...This is the next few seconds of video your browser just buffered;
- Copy the link and replace the
scf/hlsat the beginning of the link with
https://cfvod.kaltura.com/pd/p/...and you're left with the source link.
You can then use this URL to upload your video to your Perusall course.
Video hosted on your server
If your video is hosted elsewhere in MP4, MPEG, or Ogg format, you can provide Perusall with a direct link to the file. The file must not be behind a login and must be set to public.
For example, Yuja videos will need to use the permalink option. The URL should start with
If you have multiple videos that should run simultaneously (e.g. a video of a lecturer along with the slide show), enter URLs to both videos in the Video URL and Secondary Video URL field. The secondary video will display in a smaller box above the main video, but progress will be synchronized between the two videos. (Note: YouTube and Vimeo videos cannot be displayed simultaneously with other videos.)
Adding comments to videos
When viewing a video, click the Add comment button in the upper right corner of the video to pause the video and start a conversation. A blue (instructor) or yellow (student) dot will appear in the video timeline to show there is a conversation at that point in the timeline.
