Queries my dude:

Initial:

SELECT * FROM videos
ORDER BY created_at DESC, id DESC -- latest on top
LIMIT 50; -- 50 = pagesize

later: query with ?after_date=<latest_created_at>&after_id=<latest_id>

SELECT * FROM videos
WHERE (created_at, id) < (<latest_created_at>, <latest_id>)
ORDER BY created_at DESC, id DESC
LIMIT 50;

Disadvantages: cannot jump to specific page.
Advantages: very fast and perfect for infinite scrolling
