9.2.2. Create a Video
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.
- Videos should be as short as possible. Learners are more likely to finish
watching videos that are no more than 5-10 minutes long.
- Each video file that you upload must be less than 5GB in size.
- Each video should follow established file naming conventions and video compression specifications.
- The video player supports videos in .mp4, .mov, .mpeg, .webm, and .ogg
format. However, to help make sure all standard browsers can play your video,
we strongly recommend that you use the .mp4 format.
- We strongly recommend that you create copies of your videos in the
following resolutions. When multiple resolutions are available, the video
player automatically plays the best video for each learner’s device and
internet connection.
To facilitate identifying and tracking video files, we strongly recommend that
organizations define and use a naming convention for all video files in all
courses. At a minimum, your naming convention should include these elements.
- A course identifier.
- The year of the initial course run.
- A revision or version number.
For example, you might use the following naming convention.
{course number}_{year}_{section}_{subsection}_{unit}_{version}.{type}
This convention might yield the following file name.
SPU27_2015_S1_SS3_U4_v2.mp4
Additionally, when you name your video files, we recommend that you follow
these guidelines.
- Make sure that each video file in your organization has a unique name.
- Include only alphanumeric characters and underscores in video file names.
- Make sure that the video file name contains no special characters, such as ç,
å, or ó.
- Do not use periods except for the period before the file name extension (for
example, .mp4).
The following video compression specifications are strongly recommended, but
not required.
Codec |
H.264 .mp4 |
Resolution & Frame Rate |
1920x1080, progressive, 29.97 fps
Note
Typically, you export at the same frame rate that was used when you
created the media file. For example, if you create the file in a
country that uses the PAL system, you export at 25 fps
instead of the NTSC standard of 29.97 fps.
