Horizontal & Vertical Camera vs Bothways

It supports simultaneous shooting 16:9 and 9:16 video, the two videos are automatically cropped from the original video. There are horizontal and vertical reference lines on the shooting interface, what you see is what you get.

Record once. Export twice. A true creator's camera. Bothways captures video from your iPhone camera and simultaneously writes two professionally formatted files: a 16:9 landscape version and a 9:16 portrait version, with a live Picture-In-Picture preview of the alternate format — both encoded in real-time using hardware-accelerated H.264. The portrait crop isn't a dumb center-slice. Bothways uses Apple's Vision framework to detect faces in every frame and smoothly tracks the subject, keeping them centered in the vertical frame. No face visible? It gracefully falls back to a center crop. Built for creators who post to YouTube and TikTok from the same shoot. Built for filmmakers who need both formats without re-editing. Built for anyone who's tired of choosing between landscape and portrait before they hit record.
