Video format guide

MP4 with H.264 encoding is the most universally compatible video format — it plays on virtually every device, browser and platform. MKV (Matroska) is an open format that supports multiple audio and subtitle tracks. WebM is optimized for web playback and is natively supported by modern browsers.

For audio extraction, MP3 offers excellent compatibility at small file sizes. AAC provides better quality than MP3 at the same bitrate. WAV is uncompressed audio — the largest files but perfect quality, ideal for editing.
