What's a WebM File?

WebM was proposed by Google and has been becoming an open, free media file format. The WebM video format is actually based on the Matroska (MKV) container format, but usually includes VP8 encoded video and Vorbis encoded audio. WebM aims to provide high quality video compression for use with HTML5. Google says WebM's format is quite efficient and should be able to be used smoothly on laptops, tablets, handheld devices, and more. Currently, the VP8/VP9 codecs are licensed similar to the way of BSD, which means you can use it free for personal or commercial purpose, and therefore should not have those potential patent issue like H.264.

The WebM format is now widely supported by most giant companies in the world. It's indubitable that Youtube is using WebM codec to transcode uploaded video to webm. Adobe's Flash Player also supports the WebM format, as well as AMD, ARM, Broadcom, Freescale, NVIDIA, Qualcomm, TI, etc. But Intel does not support it yet. As for web browsers, Chrome, Firefox and Opera are all compatible with WebM. However, Microsoft Internet Explorer support is not so direct, only H.264 video is fully supported, but if you download and install VP8, you can play WebM videos in IE without any problem. Other applications that can open and edit WebM include the followings: Movavi Video Editor, KMPlayer, PotPlayer, VLC, iMovie, Final Cut Pro, Wondershare Filmora, Adobe After Effects, Adobe Premiere, etc.

Question: Is Safari compatible with WebM embedded video?

Answer: No, Safari is incompatible with WebM yet. But there is a workaround that helps you to play WebM video in Safari. All you need to do is to install the VLC Web Browser Plugin. Download it here. This way when you open a WebM video on a new tab, it will play the video with the embeddable VLC player automatically. If you don't like autoplay, you could install the Click To Plugin extension, which will disable autoplay and requires you to click first to play WebM video in Safari. Get it here. Too complicated? Why not use Chrome! WebM works perfectly with Chrome.
