How to change the face in a video with another face?

Hi, I believe FaceFusion is a simpler and more intuitive tool for face swapping. It's a free, open-source software that makes the process easy and accessible.

Per what Neil mentioned this can be an advanced thing and I wouldn't consider Premiere the best place to do this elegantly. If you're going for a result that needs to express intent without elegance, such as an obvious result that may look funny for a comedic piece, as one example, you might be able to produce a crude face replacement in Premiere... but beyond that, there's so much to take into account especially if there's a lot of movement, angled movement, lighting differences between replacement and replaceee content and all that.

If you're just playing around with the tools, trying to do this in Premiere can be good way to learn its masking and tracking tools, see the limitations, appreciate what's good, what's not right for this, etc. I use Premiere to replace/block simple things quite a bit... often quite effectively. AE is a workhorse of masking... with Roto Brush and the like... it's the place most folks would direct you for this.

If this is a learning experience and you just want to see what Premiere can do... find tutorials for masking effects in Premiere and tracking those masks... and how to replace and block out objects.

Blocking out is usually easier because a visible block like a blur usually doesn't have to be hidden from the viewer.

Removing objects can be trickier but for simple things (not faces) Premiere works rather well quite often. ... the other day I removed a bread crumb from a shot that zoomed into a coffee cup on a table... technically the crumb was moving given the zoom so I needed to track the crumb... then I needed to replace it with a clean part of the table... sort of like a simple clone/stamp. By common standards, that's an easy chore. I've removed objects from rooms with Premiere and all that... it's usually easy with stationary objects (despite camera movement) so long as you have good replacement content... with moving objects it's more involved. Both cases can be complex and difficult though, even for non-face simple objects. It depends on the scene and what/how you will replace things.

Replacing a face... my bet is you'll only get crude results in Premiere unless the face you are replacing it with is still along with the camera... and even if you're lucky and everything is still, it can be tough. If either are moving, I'm gathering Premiere is largely going to be crude here. Even in AE, I wouldn't consider this an easy task... but I feel someone learning can benefit from the experience if they're just playing around... to dive in a try. If it's a paid job, proceed with caution until you know what you're getting into.

Learning how to mask and track in Premiere has value generally so if you can't use it for your needs now the experience of diving in and trying will only make you better.

That's a fairly advanced thing to do for the most part. Yes, it can be done, but to do so means a tracked mask on the subject's face area, and a second video track with the other face/head showing through a tracked mask on that video track ... and tracking the position of that second track so that the face showing through that track's mask stays in the proper place on the first track. Probably will need a fair number of other things to keep it "clean". Realistically, may take some work in AfterEffects.

So ... can it be done? Yea. Easily? ... Um, probably not so easy. And depending on what you need may need someone skilled in AfterEffects also.
