That’s about what it is. A short fast zoom. It’s often used when characters reveal something, or when characters are introduced. They’re used for much more than just that though.
Here’s a .gif (animated so you may have to wait around a while) of a shaw zoom from Crippled Avengers (of which i’ve posted about on here before) where we are introduced to Meng Lo’s character. The zoom isn’t quite this fast, but you should get the drift.
Hopefully that file isn’t too large. If it slows down the page too much i’ll take it down, or lower the size.
