Drop in one video and see where it is ready to publish, where it needs changes, and exactly which requirement failed.
Drop a video into the checker. It stays on your device and is never uploaded to PostPeer.
We read its size, duration, dimensions, orientation, aspect ratio, and container.
Open each platform verdict, correct any failed requirements, then publish everywhere.
Catch rejected uploads before they enter your publishing workflow. The validator checks one file against eight common social video destinations.

Confirm that the filename uses a supported MP4, MOV, WebM, or platform-specific container.
