Making course videos available to as many learners as possible can be a complex undertaking.
To reach as many learners as possible, we recommend that you upload copies of your videos in multiple formats and on more than one hosting site.
After you upload a video on a hosting site, make sure you have the URL for that copy of the video. If you upload copies of your video on more than one hosting site, make sure you have the URL for each video location.
When a learner views a video in your course, if YouTube is not available in that learner’s location or if the YouTube video does not play, the video on the additional hosting site starts playing automatically. You can also allow the learners to download the video from the additional site.
You can use any video hosting site that you want. However, keep in mind that the site where you upload the videos might need to handle high traffic volume.
The URL for the video that you upload on a third-party hosting site must end in .mp4, .mpeg, .webm, or .ogg. (To help make sure all standard browsers can play your video, edX strongly recommends that you use .mp4 format.) The video player cannot support videos that you upload on sites such as Vimeo.
