About MTS and AAC
MTS: MTS/M2TS files come from Sony, Panasonic and Canon HD camcorders (AVCHD). They are high quality but hard to play on phones.
AAC: AAC is the successor to MP3 and the audio codec behind YouTube, iTunes and most streaming services. A .aac file stores the raw AAC stream without an MP4 wrapper.
