Your videos can contain whatever content you want to include in the course. The following resources can help you to create good video content that is based on extensive experimental research in student learning.
When you create video files, keep the following guidelines in mind.
Additionally, for information about ensuring that your videos are available to learners who use the edX mobile apps, see Configuring Video Modules for Mobile.
For courses on edx.org, in a later step, you upload your videos to edX, and edX then automatically transforms each of your uploaded video files into several different formats. For this process to succeed, you must upload videos in .mp4 or .mov format. For more information, see Uploading Videos in Studio.
Each video file must have a unique name. We strongly recommend that organizations define a naming convention for video files, and apply that convention to videos for all courses to facilitate identifying and tracking video files.
At a minimum, your naming convention should include these elements.
For example, you might use the following naming convention.
This convention might yield the following file name.
Include only alphanumeric characters and underscores in video file names. Do not use periods except for the period before the file name extension (for example, .mp4).
After you create a video, you upload the video to a hosting site so that the video is available for viewing. In a later step, you create a video component, and then you add a link to the video that you uploaded.
You might upload your videos to YouTube, or you may use a different site such as Amazon Web Services (AWS) Simple Storage Service (S3). Different sites have different compression specifications. The following video compression specifications are strongly recommended, but not required.
Videos for courses on edx.org must comply with the following specifications for YouTube videos.
