Giới thiệu về chuyển đổi WMV sang WebM
WMV was Microsoft's answer to web video streaming, while WebM is Google's open-source response. WebM uses VP8 or VP9 video codecs (royalty-free) with Vorbis or Opus audio in a Matroska-derived container. WebM is natively supported in Chrome, Firefox, Edge, Opera, and Safari (since Big Sur), making it the standard for patent-free HTML5 video. VP9 achieves compression on par with H.265 — roughly 30–50% more efficient than H.264. Converting WMV to WebM modernizes Microsoft's legacy format for today's web.
Tại sao nên chuyển đổi WMV sang WebM?
WMV cannot play in any web browser natively — Flash and Silverlight, which once provided WMV web playback, are both discontinued. WebM provides native <video> element support in all modern browsers without plugins. If you are publishing video on the web, WebM with VP9 and Opus delivers the best compression available in a royalty-free format, reducing bandwidth costs and improving load times.
