MTS is the most common file format used for HD video clips. It supports the 1080i x 720p resolution yet its file size is not that huge. MTS is the extension that is commonly used in AVCHD videos. AVCHD stands for Advanced Video Coding High Definition and these are the files that were normally burned onto Blu-ray discs for use on Blu-ray devices. AVCHD files are based on the MPEG-4 codec.
There are other variations and file extensions of MTS and these are M2TS and TS. Generally speaking, all of them are media containers that can hold audio, video, and data information. They support the H.262, H.264, and the SMPTE VC-1 video compressions. As for the audio format, they utilize Dolby Digital, DTS, or the Linear PCM.
The advantages of using this file are HD viewing experience, high fidelity sound, and advanced codec compression. The MTS file is highly compatible with almost all Blu-ray disc players, thus making it the format of choice for burning movies into a DVD.
