Pro Premiere / CapCut Tip:

When positioning auto-generated animated subtitles, set your baseline anchor Y-position to 72% to 75% of frame height. This keeps text directly in the viewer's natural eye-line without clipping into platform caption text.

Step-by-Step Instructions

4 Steps to Completion
1Phase 1

Select your target platform (TikTok, Instagram Reels, YouTube Shorts, or Instagram Feed).

2Phase 2

Choose your base resolution (1080x1920 FHD or 4K UHD 2160x3840).

3Phase 3

Optionally drop a video still or screenshot to test against UI overlays.

4Phase 4

Inspect the safe zone grid and use the copyable CSS / pixel margins in Premiere, CapCut, or DaVinci Resolve.
