How to convert M2TS to WebM or WebM to M2TS? This article will give you the reasons to convert between them and compare the 2 formats. Also, it highlights 2 fabulous file converters: MiniTool Video Converter and AConvert.
Overview of M2TS
M2TS (MPEG-2 Transport Stream) is an open-source video container format developed by the Blu-ray Disc Association. It contains audio, video, and data. Besides, M2TS is primarily used for high-definition video on Blu-ray Disc and AVCHD. It is also compatible with DVDs, hard drives, and solid-state storage cards.
Overview of WebM
WebM is a royalty-free video file format funded by Google. It utilizes VP8, VP9, and AVI video codecs. WebM also adopts Vorbis and Opus audio codecs. Plus, it is container-based on the Matroska format. By the way, WebM is compatible with Google Chrome, Mozilla Firefox, and Opera.
Comparisons of M2TS and WebM
What are the key differences between M2TS and WebM? Let’s focus on their file size and compatibility.
1. File Size
Under the same video quality, WebM is usually smaller than M2TS. M2TS occupies a lot of memory space, making it slow to transfer and share. WebM saves storage space with its smaller size, which is convenient and fast to upload and share.
2. Compatibility
WebM has better compatibility with cross-platform devices and websites, like mobile phones, smart TVs, live streaming platforms, and web pages. M2TS is primarily compatible with Blu-ray discs, hard disks, and more. Typically, M2TS can’t open with the media player on computers.
Why Turn M2TS into WebM
If you want to play M2TS videos on devices such as mobile phones, computers, and smart TVs, you can convert them to WebM for better compatibility. In addition, if you have a specific need to store and play WebM files on a Blu-ray disc or hard drive, you can convert WebM to M2TS.
