I'm seeing this a lot, I wonder if I'm missing anything. When you define a safe area for your logo, doesn't it suppose to relate to a part of the logo itself?

What 1x means?

• If I want to use this logo. Can I put 1 pixel as 1x or 500px or 1x, does both usage is alright?

I like the process video tho, I'm not familiar with smooth tool. I was like watching the whole video asking myself "Why he keeps breaking those nodes!!!"
