How to Export Threads-Ready Clips
- Set your project to 9:16 (vertical) aspect ratio for best appearance.
- Limit export resolution to 1080x1920 (vertical) or up to 1920 px wide for other ratios.
- Keep file size under 1 GB by adjusting bitrate or using shorter clips.
- Export as MP4 (H.264) for maximum compatibility.
- Set frame rate between 23 and 60 fps.
- Burn in captions during export, as Threads does not support SRT or auto-generated captions.
Safe Zones and Visual Tips
Threads crops or letterboxes videos that don’t match the recommended 9:16 ratio. To avoid cut-off text or graphics:
- Keep key text and visuals away from the very top/bottom (safe zone: ~150 px from each edge in 1920 px height).
- Preview your video in a 9:16 frame before exporting.
