Platform Validation
Check uploaded videos against platform publishing requirements before posting.
Automated Video Validation for Social Publishing
Video Validator - Check Your Video Before Publishing
Postly's Video Validator checks your uploaded videos against platform publishing requirements before they go live. It validates file format, video codec, audio codec, resolution, aspect ratio, frame rate, duration, file size, bitrate, and other platform-specific requirements.
Postly does not compress, modify, transcode, or re-encode your uploaded videos. We only validate the file using platform requirements and notify you if any issues are found before publishing.

- Check video and audio codec compatibility before publishing
- Verify resolution, aspect ratio, duration, bitrate, frame rate, and file size

How Video Validation Works
- Upload your video or select it from your Postly media library.
- Choose the platforms where you want to publish.
- Postly validates the file against each platform's requirements.
- If the video passes validation, it can be submitted for publishing.
- If issues are found, Postly informs you before publishing continues.
Why Validation Matters
Each social platform has its own video requirements. A file that works on one platform may fail on another because of duration, aspect ratio, codec, bitrate, file size, or resolution limits. Postly helps you catch these issues before the post is submitted.
- Reduce failed video uploads
- Confirm platform readiness before scheduling
- Keep your original video file unchanged
- Give teams clearer publishing feedback
