Perfect WebM file for website?

Hi guys,

I want to prepare WebM video files for my buyers (for those who work with websites). So I’m curious about dimensions and sizes of videos I would have to upload. Maybe people who work with web development could share their thoughts and ideas about it :smile: I’m interested in file size/bitrate (how many megabites in one second) you need and dimensions you would love to see (1280x720, 960x540 or smaller?)

Best regards,
