-    AVCHD (MTS) is basically a container format for MPEG4-AVC video and AC-3 Audio. It's commonly found on modern camcorders. I have pulled files off a Sony Camcorder, which records in 1080i@50Hz. It seems there are timestamp problems, and both the even and odd fields are stamped with the same time, and not 1/50th of a second apart as you'd expect. This currently breaks ffmpeg (0.6~svn20100711), and the mencoder (SVN-r31722) internal demuxer doesn't like it either. The libavformat (lavf 0.6~svn20100711) demuxer/muxer seems to handle it, so that's what we'll use.+AVCHD (MTS) is basically a container format for MPEG4-AVC video and AC-3 Audio.

 +Does everything look right? The playback on .mp4 is still obviously interlaced but it seems to be worse than before. When usually I get better playback. Previously, I had always used Adobe Media Encoder on Windows (deinterlaces the file). Can I deinterlace this file (reencode with ''mencoder'')? Are my settings right for converting this like yours?
