Download Purchased Course Videos

I have full, paid access to an online course, but the platform only streams the lessons through the browser and offers no official download button. I’d like every lesson saved as standalone video files (ideally MP4 in their original resolution) so I can build a personal library for later review when I’m away from the internet. You’ll need to work directly from my login on the course website, capture or download each video without quality loss, and return them neatly organised by module/lesson. A brief note on the method you used will help me repeat the process if the course is updated in the future. If you already have experience pulling protected or segmented streams (HLS/DASH) or using tools such as yt-dl / yt-dlp, ffmpeg, or similar workflow-automation scripts, this should be straightforward. I simply need the full set of files delivered and playable offline; no re-encoding is required unless it preserves quality and keeps file sizes reasonable. Let me know your approach and an estimated turnaround time, and we can get started right away.
