Social platform specifications can change, and each placement may have different dimensions or duration rules. Check the current publishing interface for your intended format. Create a copy that matches the destination instead of using a single export for every placement.
Set the frame for the placement
A vertical Reel, square feed post and landscape video frame different parts of the scene. Compose important faces and text within the safe area for that placement.
Keep text readable on mobile
Small captions and UI details can disappear when the platform scales a clip. Review a phone-sized preview and use captions where spoken content matters.
Let the platform requirements lead
Codec, duration, size and aspect-ratio guidance can change. Verify the latest requirements in the publishing flow before exporting.
A practical checklist
- Choose the post type and aspect ratio.
- Review the current upload recommendations.
- Export a destination-specific copy.
- Check crop, sound, captions and text on a phone.
Common mistakes to avoid
- Reusing a landscape video without checking the vertical crop.
- Relying on static recommendations from older posts.
- Assuming the uploaded file will display at its original resolution.
Questions people ask
What format does Instagram accept?
Accepted formats and constraints may change. Check current official help or the upload interface.
Should I upload the highest resolution possible?
Use a clean source that meets current recommendations, then inspect the result. Larger files are not automatically better after platform processing.
