Twitter video converter

This tool accepts a source video and exports a Twitter-ready MP4 file using H.264 video and AAC audio. It enforces Twitter's duration limit (140 seconds) and supports common aspect ratios (1:1, 16:9, 9:16) to fit feed, story, and thread formats. Conceptually, the system reads media metadata, applies user-specified constraints, trims or crops as needed, and re-encodes to a platform-friendly container. It balances quality and processing speed by applying standard encoding presets and preserves audio-video synchronization. The result is a single, shareable MP4 file with metadata describing final duration and size. This workflow benefits content creators, social media teams, and marketers who publish frequently and require consistent, compliant exports without external software. Unique value lies in tight Twitter alignment, predictable file sizes, and streamlined parameter control, enabling rapid iteration for campaigns and timely posting. Core features include file upload, aspect ratio presets, duration enforcement, bitrate controls, and optional trimming. Use cases include preparing clips for tweets, Twitter threads, and mobile-first posts with preserved quality across devices. The tool avoids watermarking, batch processing in one run, and non-MP4 outputs to maintain compatibility with social platforms and editors.
