Even if you crop the video and change the audio pitch, I'd say the video still only has a about a 50/50 chance of survival.
Google: "Videos uploaded to YouTube are scanned against a database of files that have been submitted to us by content owners. Copyright owners get to decide what happens when content in a video on YouTube matches a work they own. When this happens, the video gets a Content ID claim."
I know for a fact that Discovery hunts down their content that others have uploaded and manually files content ID claims.
