Even with a fresh dump, it would lag behind YouTube, since a video only gets in once someone links it on HN.

I took all the channels HN keeps recommending (3+ videos in Karpathy's data) and made a page with their fresh uploads as they come in: https://hn.youtldr.com

(I make YouTLDR, which writes the one-line answer under each video.)

first do a search, then on top you'll see "Filter". might try to make more prominent from main page
