Leverage browser caching

At GTmetrix I′m receiving 4 recommendations to Leverage browser caching for the following cacheable resources:

https://add.digital/wp-content/uploads/2016/01/Ink-Drop-Paint-in-water_Blue-Free-HD-Stock-Footage-1-online-video-cutter.com_.mp4 (expiration not specified)

https://www.google-analytics.com/plugins/ua/linkid.js (1 hour)
https://www.google-analytics.com/analytics.js (2 hours)

https://add.digital/wp-content/uploads/2015/08/favicon.ico (4 hours)

I′m aware that off site js files are not controled by me, so I can′t cache them. But what about the 2 other files?

How do I do this?
