Joseph Martin·Jun 2026

Demo summary

A horizontal cowboy shot is extended into a vertical 9x16 aspect ratio using the Higgsfield plugin's reframe feature to demonstrate background extension.

Step-by-step

Select a horizontal aspect ratio clip in the timeline
Apply the Higgsfield plugin to the clip
Select the reframe feature to extend the frame into a vertical 9x16 aspect ratio
Play the clip to review the background extension and check for warping

Watch out for

The process may result in a slightly over-sharpened look
Complex shots with many moving parts may experience visual warping during extension

Tips

Overlay the original horizontal shot over the extended vertical shot to verify the accuracy of the scene extension

Highlights

“This really is excellent. I mean, you can see... just perfectly extended into a vertical aspect ratio.”
