Tools for exploring .mov containers
If you just want to look inside a video file, check its individual streams and all metadata, you can use MediaInfo, which will show you everything there is to know about your file and the streams it contains.

If you want to extract, remux or reencode the video file's streams, you can use FFmpeg. If you are not comfortable using a command-line tool, there are several GUI-based programs out there (most of which are built around FFmpeg), such as XMedia Recode.
