Panasonic HDCSD9 - Convert AVCHD to AVI
This section deals with the specifics of decoding HD video from a HDC-SD9 camera. The HDC-SD9 is Panasonic’s third generation of memory card-based camcorders. The HDC-SD9 camera uses the AVCHD audio/video format. We need to tailor our switches to these formats.

Understanding the Output
First you need to find the video bitrate, audio bitrate of your HD video.You can do this by passing the video file to ffmpeg with no switches
ffmpeg -i 00001.mts The output gives the video/audio bitrates, as well as a lot of other useful information needed to decode properly.
Input #0, mpegts, from '00001.mts':
Duration: 00:00:04.3, start: 0.378211, bitrate: 10197 kb/s
Stream #0.0[0x1011]: Video: h264, yuv420p, 1440x1080, 29.97 fps(r)
Stream #0.1[0x1100]: Audio: ac3, 48000 Hz, 5:1, 384 kb/s
Output #0, vcd, to '00001.mpg':
Stream #0.0: Video: mpeg1video, yuv420p, 352x240, q=2-31, 1150 kb/s,29.97 fps(c)In this example the video bitrate is 10197 kb/s, and audio bitrate is 384 kb/s.
Decoding the AVCHD Video
This command manually specifies the video bitrate, video codec, audio codec, audio bitrate, audio channels, audio bitrate, and video resolution.
ffmpeg -i input.mts -vcodec libxvid -b 10000k -acodec libmp3lame -ac 2
-ab 384k -s 1440x1080 output.aviThere you go, a specfic example of using Ffmpeg to convert AVCHD video files from the Sony HDCSD9
