Having a good lecture recording where the sound and presentation is clear will greatly benefit the students, but any lecture recordings where the sound is indistinguishable is of no benefit to the students.
Depending on the size of the video recording, uploading to Canvas studio may take some time to complete.
By having good captions on the video, not only will it help students with accessible needs, but it also provides you with the ability to generate a transcript from the captions. Having transcripts, not only makes it accessible to everyone, but it makes the information searchable and provides a great alternative format for people who have low bandwidth needs.
Once the video has been uploaded to Canvas Studio, you are then able to embed the video into the appropriate page (e.g. Learning Materials Page) using the ‘V’ symbol in the editor. Select studio and it will lead you to your uploads.
