Export settings for vertical video

Short answer

For Reels, Shorts and TikTok, export vertical 9:16 video at 1080 by 1920 in an MP4 container with H.264 video and AAC audio. Keep the frame rate the same as your footage, and avoid exporting larger than needed. Platform limits on length and file size change, so check each platform's current help page.

Setting	Safe default
Aspect ratio	9:16 vertical
Resolution	1080 × 1920
