// ABOUT
DualCam Studio is the professional dual-stream recording app built for creators who publish on multiple platforms. Stop choosing between formats. Stop re-editing the same clip twice. With DualCam Studio, every take you record is already YouTube-ready and TikTok-ready at the same time. KEY FEATURES • Single-Lens Dual-Crop — Record 16:9 horizontal and 9:16 vertical simultaneously from one lens, both in true 4K, with no quality loss between framings. • Multi-Camera Concurrent — Capture front and rear cameras at the same time for reactions, interviews, vlogs and behind-the-scenes content. • True 4K Master Files — Each output is a full-quality master, not a re-crop of a preview. Recordings are written through dedicated writer pipelines for broadcast-grade results. • Real Zoom Per Camera — Optical and digital zoom per device, with smooth ramps and cinematic 0.5×/1×/2× switching. No stretching, no fake digital zoom artifacts. • Independent Viewports — Set framing, mirroring, rotation and crop per output view without affecting the other. Master and PiP behave like two real cameras. • Hero & Context Framing — Smart auto-framing tracks the subject in the Hero view while the Context view holds the environment, hands or product. The two views complement each other instead of duplicating. • Zero-Copy GPU Pipeline — All transformations happen on the GPU, so the device runs cool even during long 4K sessions. • Deterministic Export — Crops, rotations and framing are stored as metadata, not baked into preview. Exports are recomputed from the masters for pristine final files. WHO IT'S FOR Content creators publishing simultaneously on YouTube and TikTok, Reels or Shorts. Interviewers and podcasters who need a clean wide shot plus a vertical angle. Coaches, demonstrators and tutorial makers who film a subject and a context (hands, screen, product). Solo videographers who would otherwise need two phones and an editing suite. WHY DUALCAM STUDIO Most "dual" camera apps simply mirror the preview into a second frame. DualCam Studio doesn't. It records two true masters with their own metadata timelines, then composes the final files at export. That means your 16:9 and 9:16 deliverables are not crops of the same preview — they are independently framed productions. REQUIREMENTS • iPhone with A12 Bionic or newer for full 4K dual-stream • iOS 16 or later • Adequate free storage for 4K masters PRIVACY DualCam Studio records locally on your device. We do not upload, analyze or share your footage.
