MP4 and WEBM
MP4 with H.264 video plays on virtually every phone, browser, TV and editor.
WebM uses the open VP9 and Opus codecs and is made for playback in web browsers.
In Settings you can cap the resolution (4K down to 480p) and choose High, Balanced or Small file quality.
Why convert on your computer?
Online converters upload your MP4 files to someone else’s server, limit file sizes and often add queues or watermarks. nxtconvert does the work locally with the same engines professional tools use, so it’s private, works offline and handles large files and big batches.
