Teach Video Download Techniques

I have more than fifty game-related videos hosted on a personal website that loads them through a custom web player. When I open Chrome DevTools all I see are blob: URLs, no .m3u8 or .mp4 links, so my usual tricks don’t work.

My priority is to learn a repeatable workflow that lets me fetch every video on my own whenever I need to, not just receive a one-off batch. I’m comfortable following clear instructions but I’m not a developer, so the steps must be beginner-friendly and Windows-compatible.

Here’s what I need from you:
• A step-by-step guide (text or short screen-recording) showing how to locate the real media stream, handle any HLS/DASH manifests, and assemble the final file.
• A ready-to-run script or command template—ffmpeg, yt-dlp/youtube-dl, Streamlink, or another tool of your choice—that can batch-download 50+ videos once I supply the page URLs.
• A brief Q&A session after delivery to be sure I can reproduce the process unaided.

I already have written permission from the content owner; this is purely for personal offline use. Let me know your proposed approach, how long the job will take, and your fee.

Thank you!
