Make a video look like it was taken from further away
When you shoot from further away you use a "longer" lens, in other words a lens with a longer focal length. This has a few effects, that you'll have to fake to make it look real.

First, the perspective tends to get flattened with long lenses. You've probably seen this in the classic cinema trope of a long shot of a crowd walking along a footpath, where everyone seems to be about to step on the heels of the person in front. This is because the angle of view is very shallow, so someone in the foreground is not going to be much bigger than someone in the background. Conversely a wide angle shot has exaggerated perspective. See just about any Public Enemy video where Chuck D and Flavour Flav pop their heads into the camera and get massively bigger than the people in the background, just by moving a few feet.

This perspective  compression is going to be very difficult to fake after the fact, unless you're really good at rotoscoping and compositing.

If you look at the long lens shot you'll also see that there's often a pretty shallow depth of field. This is often used by film makers, like Scorsese in this clip from Taxi Driver to highlight the central character, by racking the focus to follow them.

Now a wide angle lens and a phone lens (for different reasons) have very deep depth of field. So you'll have to selectively blur the foreground and background. However if you do this without matching the geometry of a telephoto lens (the compressed perspective discussed earlier) it's going to look like it's actually teeny-tiny, because it will look like another kind of lens with a shallow depth of field, a macro lens.

Another thing that telephoto lenses do is magnify any camera movement, where small movements are magnified by the narrow field of view. You could fake this by reframing, using a wiggle expression to drive the movement, however it might not necessarily achieve the look you want: If you're shooting telephoto you're unlikely to hand-hold the camera because it would look awful, so you'd lock it down on a tripod - see the shutterstock and Scorsese examples.

So depending on what the subject of your video is, this could be quite a challenge. Of course if your phone has a 4K sensor, you could actually make a telephoto shot out of a wide by just cropping. Of course this reduces your resolution, so it will look pretty ugly on most phones, and obviously you have to compose the shot with all the action in the center.
