How can I get metadata, such as frame rate, resolution, audio and video bitrate, from a video file? Can this data be obtained from players like VLC and Media Player Classic?
Most players will have a way of giving this information. It may also be provided by the OS, depending on which one you are using (Windows 7 shows it in the status pane).
In any case, what you can do is to install a shell-extension like MediaInfo to give you this information on demand.
I use Super software for this, is shows everything about a media file and can covert it to other formats.

Drag the file to the lower pane of the software
Then double click the file in the lower pane to see the file properties, it also has an extended analysis feature which gives much more information, looks like it uses the mediainfo website to gather this info.
