Part 1: About AVCHD Format

AVCHD is a video format and the name stands for Advanced Video Coding High Definition. With it spelled out, you can probably guess that it's a high-quality video format. AVCHD will give you television viewing quality on any device! It is developed Sony and Panasonic collectively, which is originally designed for HD camcorders use for digital recording and HD video playback. It records video at a resolution, ranging from 720p to 1080p or higher. Though some brands of HD camcorder also employ MPEG-4, they are not as popular as AVCHD video anyway. Videos in AVCHD format can be burnt to a standard DVD disc that can be playable on an HDTV and Blu-ray Disc player.

Supported Video Formats
AVCHD supports a variety of video resolutions which was further extended in 2011. Most AVCHD camcorders support only a handful of the video and audio formats which are allowed in the AVCHD standard. When it comes to video formats, AVCHD supports both standard definition (AVCHD-SD) and high definition (AVCHD 1080i) interlaced video.
Supported Audio Formats

Most AVCHD camcorders record audio using Dolby Digital (AC-3) compression. Stereo and multi-channel audio is also supported. It is important to note that as a distribution format, while DVDs that have the AVCHD file recorded on it, will be called a AVCHD disc, it cannot be played on the standard DVD player, but can be played on most Blu-ray disc players.

Audio, video, subtitle, and ancillary streams are multiplexed into an MPEG transport stream and stored on media as binary files. Usually, memory cards and HDDs use the FAT file system, while optical discs employ UDF or ISO9660.

Audio and Video File Extensions
AVCHD files are stored with a .MTS or .m2ts file extensions, which mainly depends on the brand or whether you're copying the files to a PC or Mac. There is no significant difference in the contents of the video files that use different extensions.

The advantage of AVCHD MTS/M2TS video

1. Recording HD image onto random-access media, including 8cm DVD discs, hard disk drives and removable flash media such as SD/SDHC memory cards and "Memory Stick" cards. This is crucial factor for why AVCHD format could weed out other type-based HD video recording formats, like HDV.

2. AVCHD utilizes MPEG-4 AVC/H.264 (AVC) video compression codec and either Dolby AC-3 (Dolby Digital) or linear PCM (is used for the lossless encoding of audio data) audio compression codec. It permits AVCHD MTS video to feature Efficient Reduction in the Size of the data file, provide Sufficient Shooting Time while maintain the High Picture Quality of the HD recording.

3. Compatibility with Blu-ray Disc. Since the structure of AVCHD video is derived from the Blu-ray Disc specification, it has been designed to be compatible with Blu-ray Disc format and can be used for authoring of high definition video on DVD media, though not all Blu-ray players are compatible with AVCHD discs.

4. What makes AVCHD an Unique and Advanced Codec Compression (comparing with other Videos like AVC, MPEG-4, AVI, MKV, MOV, etc) is that it includes features to improve media presentation such as: Menu Navigation, Slide Shows and Subtitles.

The same case with DVD (somehow AVCHD video is similar to DVD movies, like vivid image and selectable language track), AVCHD video allows you to freely choose the audio/language tracks. If your native speaking is not English or you want to learn other language, it is definitely a useful feature far beyond your imagination.

Detailed information about what AVCHD is doesn't end here, keep reading to dig out all the mystery of AVCHD.

If your current media player is already compatible with one of these options, go ahead and select it. While there are some minor quality differences between these three formats, it's not enough for you to notice unless you're watching the videos on an extremely large screen. So, it's worth saving yourself the time and trouble and using a format already playable on your device.
