my name is Marcell, I'm living in Germany as an expat. As I really like learning German by watching videos, I decided to make this process a bit more efficient. First, here are two of my favorite tools:
YouTube: It's fun, engaging, beyond the content you get the value of the real spoken language. I find it especially useful with subtitles.
Linguee: The best dictionary I know. You get not just the meaning, but explanation, grammar forms, examples.
So I decided to combine the two. You can click on each word of the subtitle and it will hit up linguee.com immediately. Here's an example (German, A1) https://www.interpolly.com
If you'd like to try it with another video (other language, other level, etc.) drop me a message, hopefully I can help. I built this primarily for myself, but due to the good feedback I decided to make it public very soon.
Have a nice day!
