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
