2Camera+ vs PostProof

2Camera+ is a dual-camera app for creators and everyday storytellers. Capture the front and rear cameras at the same time, combine them in picture-in-picture or split layouts, and put “what you see” and “your reaction” in one frame — less post-production stitching. Highlights - Dual live preview: On iPhones that support concurrent multi-camera (MultiCam), preview front and rear at once; unsupported devices show a message and fall back to single-camera mode. - Picture-in-picture (PiP): One main and one overlay feed by default; drag the overlay, pinch to resize, double-tap or use controls to swap main and secondary. - Split layouts: Side-by-side or stacked splits — switch layouts to match your shot. - Overlay shapes: Multiple mask styles (e.g. rounded rect, circle, star) to style the secondary view. - Synced still capture: Capture both cameras and output a composite (format and resolution depend on device and system). - Synced recording: One composite video file (typically HEVC or similar, per device and settings) for easy sharing and editing. - Save to Photos: Save composites to the library when write access is granted; if denied, behavior follows sandbox limits and in-app messaging. - Orientation: Preview and output follow device orientation where possible for a consistent WYSIWYG experience. - Dark Mode: UI follows system light/dark appearance. - Localization: Interface strings follow system language where available (exact languages depend on the build and App Store locale settings). - Teleprompter (optional): overlay notes, editing and scrolling; prompt text is not burned into exported photos or videos. - Single-camera capture: Settings switch to one camera for lower power; single-file still or video output. - Preview framing: full-screen or 16:9 / 4:3 / 1:1 style ratios aligned to screen long edge. Ideal for vlogs (presenter + subject), online teaching, events, and any shot that needs two angles on one screen. Full dual-camera capability requires hardware and OS support for multi-camera capture — try on a real device for the best experience.

NEW — Retention Radar: a whole-clip pacing timeline that finds the boring middle. Motion-energy curve, scene-cut count, and located dead spots with timestamps, all measured on device. PostProof is a final-pass video checker for creators who want to catch publishing problems before export. Import a short-form video, pick a generic layout, and PostProof shows pixel-accurate safe zones, stylized feed controls, caption risk with coverage percentages, face risk, cover options, trim controls, export settings, and a publish-readiness plan in one focused workflow. What you can do with PostProof: - preview a clip inside a generic short-form video overlay - run FrameCheck to see whether text, faces, or details may be covered - compare coverage results across the bundled layouts - get a ranked Publish Readiness Plan with the highest-priority fixes first - review safe-zone, audio, readable-text, frame-fill, cover, and Stop Score checks together - get a Stop Score, muted-readability score, loop score, and tap-to-open score breakdowns - place a short caption that snaps inside the center-safe area - browse an offline specs cheat sheet for aspect, duration, resolution, bitrate, and frame rate - use bundled caption prompts and tags for drafting posting copy - choose a cover frame scored on exposure, sharpness, contrast, and subject presence - trim the start and end before export - export a 720p or 1080p posting copy - save each run to a local Proofs history - see a Stop Score trend chart across saved proofs - compare two saved proofs side by side - open a full detail sheet with score breakdowns and caption copy Layouts use generic, layout-descriptive names such as Tall-Caption Vertical, Right-Rail Vertical, Title-Bar Vertical, and Square Timeline. PostProof uses no social-platform brand names. PostProof is not a social network and does not post for you. It is the quick check before you upload: make sure the caption is readable, the face stays clear, the cover is strong, and the clip is ready to share. Privacy is simple: - no account required - no developer cloud - no analytics SDK - no advertising SDK - no tracking - video analysis runs on device PostProof is not affiliated with, endorsed by, or sponsored by any social media platform.
