Is it better to learn a lot of vocab first before diving deep into grammar?

Hey all! Beginner learner here. I’ve been using Memrise primarily to learn and get a feel for things. I’ve started watching some beginner korean story videos on YouTube to start learning how sentences are structured and hear more speaking/pronunciation. My issue is, as I’m trying to learn the grammar, I’m having to stop nearly every other sentence just to learn a new word.

This turns a 5 minute video into 15 minutes as I have to learn both new vocabulary, pronunciation, and theory behind grammar/sentence structure. Thus, I was thinking perhaps I should get a better grasp of vocab before diving into grammar. That way, I can focus less on learning new words in my grammar lessons and put more focus on sentence modifiers, enders, structure, etc.

Curious how others tackled this problem?
