Turn this MP4 into WebM.
Make a silent website animation, or keep the sound. Choose the width, frame rate, quality and exact section, then check the WebM before downloading.

Conversion runs at playback speed, so a 12-second clip takes roughly 12 seconds. Keep this tab active until it finishes.
Useful to know
Four quick answers.
Know the limit.
WebM is not automatically smaller or better. Width, frame rate, bitrate and clip length decide the result, and some older apps still prefer MP4.
What should I check?
Play the exported file from beginning to end, then check its dimensions, motion quality, file size and whether it loops cleanly on the real page.
One useful thing.
WebM is a video format built for the web. Start with 960 px, 24 fps and no audio for a silent landing-page animation, then increase quality only if you can see a problem.
