Editor Sequence

CookieGoals Posts: 2 Just Starting Out*

Hello! I have been a Hitfilm user for years but this is my first time using the discussion board. I apologize in advance if this is under the wrong category.

Never have I ever used the option of "changing editor sequence settings to match clip" in Hitfilm. I decided to use it recently and clicked the option "yes, I would like editor sequence to change settings to match the clip". After doing so, I noticed a blue line that began to load a little bit above the clip in the "Editor" section. Hopefully the attached image gives an idea of what I am talking about.

I was just curious as to what this blue line is meant to do? I've noticed that it tends to freeze at parts where I input text in a Composite Shot as well. Is this normal? Sorry if this may seem too confusing.
