NEW โ€” 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.
