Zooming while filming video on the iPhone?

I'm having a hard time finding anything concrete on this, it doesn't seem like too complicated of a request. The goal is to simply start recording and then zoom from one end to the other all the way in to all the way out, even including digital but cannot find anything on either a technique or a third party app, though this seems like it would be fairly easy for a developer to create.

I know you can pinch and zoom, you can also hold for the wheel then roll it from side to side but you have to pull your finger off and move it to continue the scroll so it's choppy, the goal is a single shot smoothly scrolling all the way.

Wish I had time to write you the app. Would be nice if such app let you set the two zoom extremes, and the time intervals in each direction.

This is a great idea. IDK why Apple hasn't already done it.

Or a third party developer for that matter, at least from what I can find.

How about being able to record synchronized parallel tracks on both lenses with a framing guide (like a green box) for the telephoto alignment. Then you could render an interpolated zoom in post (perhaps with a zoom curve editor), and it would look just as good as a live zoom.

It would need it too, as it is I ran a test today (iPhone 17 Pro Max) and I can sort of get it smooth but it's automatically pausing briefly as it switches between all 3 cameras.

Then perhaps it lacks the bandwidth to read more than one CCD at a time. There can be a lot of correction going on in video recording: my friend was recording fall colors as we drove I94 through Minnesota a few years ago, and the passing image was rock steady as you could see the car bouncing up and down. I suppose this also means the sensor has excess margin top and bottom.
