Part 6. Why Convert M2TS to MKV File

One situation you need to convert M2TS video to MKV format - If your M2TS files is ripped out of Blu-ray Disc, after converting Blu-ray M2TS video to MKV formats, you have decrypted M2TS file stored on Blu-ray Disc to open source MKV video. It is a desirable Blu-ray Disc backup solution, since you can shrink full content of 50G Dual-layer BD m2ts to 10G video in MKV format, yet the degradation is unperceivable to your eyes!

At the mean time, you can keep original BDAV M2TS audio track, subtitle track, video track (for multi-angle BDAVs), and menu within one single Matroska file. That means, without any Blu-ray movie features abandoned, you can make perfect Blu-ray Disc backup in MKV format. The HD MKV movie viewing experience is just as fantastic as when you playback original Blu-ray M2TS video.

If you pursuits minimum output MKV file size, you can get even smaller size by reducing these redundant Blu-ray elements. For instance, some chapters deliver little information, like Movie Extras, you do not have to reserve computer hard disk space for them. Also you do not need to keep all language and subtitle tracks in your output MKV video if you feel they are useless. And if you transcode the MPEG-2 encoding to a more efficient encoding like H.264, then the new file could use the MKV container format and be substantially smaller.

The other occasion you need M2TS to MKV converting - if you are HD Camcorder shooting lover, then you have great chance to deal with AVCHD camcorder, which records video in M2TS format. Thanks to AVCHD M2TS and MKV video employs H.264 video codec, after converting M2TS to MKV format, you will have lossless output quality. The export MKV image is as appealing as your 1080p AVCHD recordings.

And also, as mentioned above, MKV is open source video format. Open source programs have an arguably higher potential for more creative solutions and broader implementation. When playback AVCHD M2TS video, you definitely have to pay close attention to overheat of your computer, high-end CPU and Graphic Card required, or even you hardly find competent AVCHD Player software. But after converting AVCHD M2TS video to MKV video, there awaits many free MKV players and free MKV editors.

To sum up, no matter your source M2TS video is ripped off from Blu-ray Disc or AVCHD recording, one thing you need to note is that - if you want to use a stand-alone device like a HTPC, Popcorn Hour or a Western Digital player, you'll probably have better compatibility with the MKV container than M2TS.
