If you mean doing an aspect change in post - it's really easy - just depends on the software - it's different in each one. If you let me know what software you are working with, I can probably help you.

 

If you mean change aspect in camera - that is a little different, and can't say I have ever heard of this being done. Usually, aspect in camera is gate and format dependent in film, though in digital it can often be changed in the menu settings, with different quality results.

Landon,

I am using the Adobe CC 2017 software. Thanks!

An aspect ratio change between cuts is as simple as a normal cut. You would only have to decide whether you wanted the two aspect ratios to share a common top/bottom or common sides.

 

With common top/bottom you would need to pillarbox the 1.78:1, and with common sides you would need to letterbox the 2.39:1. If the idea is to make the 2.39:1 feel larger and more epic by comparison, then I would suggest common top/bottom so that the 2.39:1 frame is physically larger.

 

If you want the aspect ratio to change in shot, then you would need to add that effect in post. It could be as simple as a one-frame pillarbox/letterbox overlay, or a more complicated animation of the frame edges expanding over several frames. Perhaps the effect you are thinking of is something like the the original 1950s CinemaScope presentation where the curtain slowly opens to reveal the full width of the widescreen?

 

Or are you asking about how to do the aspect ratio change in-camera?

Hi Satsuki,

I've been looking for tutorials on your last comment regarding expanding frame edges over several frames in the shot. I have footage the we are using an anamorphic crop .png over, but I am interested in transitioning from the crop to the full ratio it was shot in. Would you happen to have a resource right off hand? The scene is an over head drone shot of open fields and just want to give the feeling of expansion. Thanks in advance!
