AI editing for short-form video
A good short-form video is more than a landscape clip cropped to 9:16. It needs a moment that stands on its own, tight pacing, mobile-friendly framing, readable captions, and enough visual movement to keep the edit from feeling static. Cubix handles those editing steps while keeping the finished clip fully adjustable.
What Cubix can edit automatically
Tighten the pacing
Remove dead air, hesitation, and unnecessary gaps without making the clip feel unnatural.
How to edit short-form videos with AI
