About GIF → MP4
Why convert GIF to MP4?
MP4 with H.264 + AAC plays on every device, browser and editor. Convert from GIF when you need a file you can share or upload anywhere without worrying about codec support. Converting your animated GIF to a real video typically shrinks the file by 5–10× at the same visual quality, with no 256-colour palette limit. Useful when a GIF is too large to upload or send.
About GIF
GIF is the original looping animation format. Every browser, chat app, document editor and forum can embed it inline without a video player. The trade-off is brutal: GIFs are capped at 256 colours per frame, carry no audio, and are far larger than equivalent video. vexo extracts the trimmed range, resizes if requested, builds an optimised palette, and writes a single GIF — useful for short reactions, demo loops and email-friendly clips.
About MP4
MP4 is the default video container of the modern web. With H.264 video and AAC audio it is the format every iPhone, Android phone, Windows machine, Mac, smart TV, video editor, social platform and browser understands without extra codecs. vexo encodes MP4 with the H.264 'veryfast' preset and 128 kbps stereo AAC — a safe default for talking-head, music and screen recordings.

Supported formats
MP4 is the safest default for web and mobile playback. WebM gives the smallest files for modern browsers. GIF is for short, soundless animations.
WMV, FLV and other legacy/streaming formats are not supported in this version. Please convert those to MP4 first using a desktop tool.
