We discovered that Zoom creates very large files, the first Let's Go Online video was 55 minutes and 500mb. This will take much time and bandwidth to upload and download. An alternative is to save zoom videos locally and then compress them, which Handbrake can do with you. Of course, if only audio is important, zoom also creates and audio file and you could post that. However, if you need the video, Handbrake can manage the file size for you.

Here's How (the attached file includes screen captures, which makes this much clearer). You can also find instructions online that might be Windows-based. These are for Mac system.

How to Use Handbrake to Compress Zoom (or other video) Files (Fast Version by Porter)

Download Handbrake: https://handbrake.fr/
Follow the installation instructions.
Launch Handbrake.
Open Source:

Locate and Select the File that you want to shrink:

Find Presets, near top-left (Very Fast 480p 30 will render a small, fine-for-zoom file):

If you want to get very fancy, there are many, many presets to tinker with.

Save As, bottom left, to Name the file and Browse (right) to choose location:
Push the Green Start Button. Handbrake will tell you when it is done.
You should now have a much small file to post to Panopto in Canvas.
