Automated 9:16 Background Blur Padding
Eliminate ugly black letterbox bars when sharing landscape clips to vertical social feeds. PostAutoPro creates a professional, soft-focus background duplicate while keeping your central content crisp and centered.
Why Background Blur Padding Outperforms Cropping
Cutting off the left and right sides of a 16:9 video often loses critical speakers, product demonstrations, subtitles, or key graphical elements.
Retains 100% of your source horizontal footage, centered perfectly with an auto-scaled blurred duplicate behind it. High visual aesthetic, zero lost context.
GPU-Accelerated FFmpeg Transcoding
Transcodes video files in seconds in the cloud with zero CPU overhead on your local computer or mobile device.
Per-Platform Destination Control
You decide when to apply blur padding. Keep 16:9 for YouTube videos, and enable blur padding only for TikTok, Instagram Reels, and YouTube Shorts.
