Our current 100 MB file size limit in Moodle is a necessary step in ensuring the accessibility and longevity of our learning management system, but it will often mean editing and compressing video files prior to adding them to your course. Here, we have collected strategies for keeping or converting video clips to under 100 megabytes. Please keep in mind that video files by nature are very large in size, and that this is not an exact science. Please expect to spend some time experimenting; finding your best solution may require some trial and error.
Where possible, plan in advance to either record a shorter video, or to make a series of clips. (This is often the better pedagogical goal in any case; your learners’ attention is likely to wane after viewing five minutes of video content.) While the file sizes that Zoom makes are variable, depending on what happens on the screen, shorter is almost always better, and the most basic way to keep files under the 100MB limit is to limit your recording time per file to well under ten minutes. Those files can be uploaded to Moodle directly, with no need for further compression.
When in a Zoom call, each time that you turn on the recording feature, and then turn it off again, Zoom will create a separate video recording. One way to minimize file size, therefore, is to turn the recording tool on and off as you go. This can be a challenge if running a live session. Consider asking a trustworthy participant in the meeting to do this for you, and turn on the ability for that participant to record the meeting.
If you are recording a full course session or a lengthy lecture, there two ways to keep the file size under Moodle’s 100MB limit: you can edit a single long file into a series of one or more clips, or you can compress that full file, keeping it as one file but degrading the image quality. We’ll discuss each of these in turn below. Fortunately, Mac and Windows 10 users both have access to free built-in tools for basic video editing.
When Zoom generates a meeting recording, the software already compresses it quite a bit. A video of about 1 hour will be somewhere in the 300MB range in size. The actual size can vary, however, due to a number of factors, including the device on which it was recorded, or what was happening during the meeting. For example, lots of video conversation back and forth between multiple users, such as during a seminar discussion, will generate a larger file than a shared screen of a static image, such as during a virtual lecture.
To reduce Zoom meeting recordings down to under 100MB, you can further compress the file using a free software title called Handbrake. Once you have Handbrake successfully installed on your machine, here are the steps you would take to further compress your recording.
