Problem
A split-screen tutorial becomes unreadable in vertical format because each panel is reduced below the minimum useful visual size instead of being re-edited sequentially.
Solution
Root Cause / Diagnostic:
Compressing a horizontal side-by-side split-screen layout into a 9:16 container shrinks horizontal resolution by roughly 70%, rendering small UI text, cursor paths, and code completely illegible. Treating multi-panel horizontal workflows as a static scaling problem rather than an editorial sequencing problem causes immediate mobile viewer fatigue.
Actionable Step-by-Step Fix:
1. Re-Edit Panels Sequentially: Dismantle the simultaneous split-screen and cut between full-screen zooms of the UI step and the resulting output sequentially.
2. Stack Panels Vertically at 1:1 Scale: If simultaneous viewing is required, stack the two panels vertically (top and bottom) and crop each panel to focus tightly on the active UI window.
3. Apply Dynamic Punch-In Zooms: Crop into the active interface element at 200–300% scale so desktop text scales to a minimum of 36pt font equivalent on mobile displays.
Pro Creator Tip:
Never shrink a side-by-side desktop tutorial into vertical video; convert the side-by-side layout into a top/bottom vertical stack with 150% zoom on the active application cursor.
