Why convert WebM to MP4?
WebM is the default format for Chrome screen recordings and browser-based capture tools. It plays fine in Chrome and Firefox, but is not natively supported on iPhone, most smart TVs, or many video editors.
Converting WebM to MP4 (H.264) gives you a file that works everywhere — no plugins, no compatibility issues.
