Un-trim (revert trim) a Quicktime file

I just Trimmed and Saved a QT file with QT Player Pro 7 - But I did it wrong!
How to un-trim???  I don't want to have to export a 2 hour long video again!

Well here is the solution:

1) Get the app Hex Fiend here:

2) Open your mistakenly trimmed QT file
3) Search for the text string "free" (like free...lmvhd)
4) Manually replace "free" with "moov"
5) Save

Hop! The trimming is gone! Yeah!  Thank you juliejuliejulie, thank you!
