Part 1: Warming Up Before Converting M2TS/MTS to FLV on Mac

I bet you have already learnt a lot about FLV video file. Therefore I guess we can bypass the introduction to FLV here in this part. But still, before we start to convert M2TS to FLV Mac or convert MTS to FLV Mac, we'd better figure out what M2TS is, what MTS is and the differences between those two video files.

What is M2TS?

M2TS is a file name extension used for the Blu-ray Disc Audio-Video (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is used for multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container. This container format is commonly used for high definition video on Blu-ray Disc and AVCHD.

What is MTS?

MTS is a file extension for an AVCHD (Advanced Video Coding High Definition) video clip format for high-definition video.

Differences between M2TS and MTS:

Before the recorded HD videos are collected, the format they display on the AVCHD digital camcorders are MTS. But after they are collected or upload to software, their extensions are changed to M2TS. Although MTS and M2TS are different extensions for the same AVCHD video, they still has a slight difference. That is in the M2TS files, videos are saved in the high def Blu-ray BDAV format. The video data on the Blu-ray discs can be encoded in two different video codecs: MPEG2 and H.264. And the audio data can be even in five audio codecs: Dolby AC-3, MP2, DTS, AAC or linear PCM 7.1.
