Hello there, @barthle_t ...
Sorry to see that your question has been sitting out here unanswered for such a long time. When you posted this question back in May, it wasn't really possible to find your recorded videos. But, that has changed now with a recent Canvas release. Please check out Canvas Release Notes (2020-12-19) - Canvas Community. Specifically, check out the section on New Rich Content Editor: Uploaded Media File Placement. This short video will also explain this in more detail: New Rich Content Editor: Uploaded Media File Place... - Canvas Community.
I hope these resources will be of help to you. Sing out if you have any other questions about this...thanks! Take care, stay safe, and be well.
