MP4: Metadata tags.. How to add?

[a.fowler]

Hello,

I have several hundred WMV video files with bad embedded author/title/date information that I am about to convert to MP4 for use on an iPod using MediaCoder.

However, the correct information is correctly encoded in the file name.. i.e. "title-author-date.wmv"

So, two questions:

1) Can I set MediaCoder to extract the tags from the file name?

2) Failing that, is there command-line program I can use to clear the MP4 metadata and add my own? (I'm willing to write a Python script to automate it, if needed.)

-- Thank you
