Supported Video Formats and Technical Limits
Twitter accepts several mainstream video formats, with MP4 being the most reliable across devices. The platform prefers H.264 video encoding and AAC audio encoding to balance quality and file size. Keeping your videos within the size limit and recommended resolution ensures quicker processing and better playback.
Video Duration and Aspect Ratio Guidelines
While Twitter previously supported longer videos, the current focus is on short, engaging content. Aim for aspect ratios that fit seamlessly into feeds, especially vertical formats for mobile viewers. Adhering to duration and ratio recommendations reduces the chance of upload issues and improves viewer retention.
Upload Best Practices and Compatibility
For the best results, compress your video without significant quality loss and use the standard MP4 container. Ensure your footage is well-lit and clear, and preview the upload on both web and mobile to confirm playback. Following these practices makes your content look sharp on any device or connection.
Advanced Tips for Creators and Developers
Power users and developers can leverage specific codecs and upload endpoints to streamline workflows. Choosing the right combination of format, resolution, and bitrate helps you maintain quality while staying within platform restrictions. These advanced adjustments are especially useful for media teams and automated publishing setups.
