When editing my video, I'd like to zoom in on my friends face, and make it so he also isn't blurry. Along with this, I'd like to make sure the entire video isn't blurry too. How can I do this? If a source link is required to see the video, please let me know, I'd be happy to work with one of the staff members to learn how to edit

Hello and welcome!

With a given output resolution, zooming-in with DVE reduces resolution by nature. That makes the picture look blurry more or less, depending on the zoom-factor.

I think you are after something magical and impossible? (What resolution is your original footage in, and what resolution are you going to be rendering to?)

Though, it did remind me of some deep-learning research I was reading about the other day: www.technologyreview.com/s/601258/artificial-intelligence-can-now-design-realistic-video-and-game-imagery/

However, even if Lightworks had this bleeding edge technology, what you would get when you zoom in is a generic face (the average of all the similar faces in the data it was trained on), not your friend's face.

That is the decisive question, and:
Is your material an image or a video?

Unfortunately, Lightworks still has weaknesses in this regard.

Assuming your footage is 4k, then you could export with the pro-license in 4k.

My answer to the initial question is, use a good optical zoom on your camera when recording.

I suspect that you've seen the "magic zoom" where in a cop show they take security footage from a street camera then zoom in to someone's phone and read the text on the screen. I hate to break it to you, but that's pure fantasy. There is nothing that can do that.

You will only be able to zoom in on your friend's face to a certain amount before it becomes too soft to use. There are external applications that will get you a slightly better result, but they have their limitations too - for example BorisFx UpRez can do a fair job of expanding a standard definition image to high def, but that's a little over a 2:1 blow up, and the quality of the end result is very dependant on the quality of the original footage.
