0:42 - 0:43 seconds?
How is this done. If I slow it down it looks so simple.but am unable to achieve it. If anyone who knows how could be of help?
As long as you don't post any actual link to whatever clip you are referring to you won't get any useful answers.
Well, that's not a seamless zoom, they just do in such a way that it appears that way.
I'd just search some tutorials on this but it's a combination of taking your wide shot and your close shot and matching them together during your animated zoom, some blur, etc.
Actually, what first came to mind to me was Andrew Kramer's Earth tutorial. Same concept, actually easier since you are only doing basically two images/video where he does multiple here. Once you see how he does two, you should get it.
