Hello dear Stackoverflow ppl,

I know HTML and so I want to code myself a little website with a collection of all of my favourite videos from youtube and other websites I have currently stored as simple bookmarks in my browser. To do this I need the embed link of all the videos you can get by clicking on "share" and "embed link" under a video (then you will get an iframe with thumbnail and so on). However I need to do this not just once, but for hundreds and thousands of videos, so I can't copypaste all of them one by one. Kind of a batch process is required. I have absolutely no idea on how to do this. I want a html document with many thousands of iframes as an end result.

Thank you for any suggestions <3
