Redirect / video requirements
Upload the highest resolution source video or image available without letter or pillar boxing (No black bars). Most file types are supported. However, for videos, we recommend H.264 compression, square pixels, fixed frame rate, progressive scan, and stereo AAC audio compression at 128kbps+.
Consider leaving roughly 14% (250 pixels) of the top and bottom of the video free from text and logos to avoid covering these key elements with the profile icon or CTA. This means, if your video is 1080x1920, ensure key elements appear within a 1080x1420 title-safe area.
