Only the soundtrack survives: the video stream is dropped, and the MP2 audio inside the MPEG file is re-encoded as ALAC.
The size drop is dramatic because the video stream is where nearly all the data lives. A minute of MPEG runs around 41 MB; the extracted ALAC is roughly 6 MB per minute.
ALAC is lossless, but the ceiling is the soundtrack already inside the video. That track is usually MP2, which is lossy, so ALAC preserves it exactly rather than improving it.
The source can carry more than one audio track, for example alternate languages or a commentary. Extraction takes the primary track.
This tool takes the audio track from inside a MPEG file, a MPEG-1/2 Program Stream container from 1993, and saves it on its own as ALAC. Everything visual is left behind.
MPEG comes from MPEG and dates to 1993. It usually holds MPEG-1 or MPEG-2 video with MP2 or MP3 sound, and those streams set the ceiling for anything converted out of it.
ALAC comes from Apple and dates to 2004. It carries losslessly compressed audio (ALAC), and without installing anything it plays on macOS and iOS.
