"Industry standard" for video clips

I know this is a suitably vague question but I am doing a personal favour for a friend and helping him negotiate a content-based license for a video he is producing.

The video is sports-oriented, specifically mountain-biking. Stills and portions may be incorporated into a television series.

The royalty provisions are for a percentage of gross and advertising over and above a set amount i.e. if the distributor will be paid above a certain amount, then my friend, the video producer will receive a percentage.

So, my question - what is the range of "industry standard" for such a video and what is customary licensing practise for such a deal; ie. is this royalty method commonly used or does the video producer "normally" receive a straight percentage of gross and advertising.

I know this is a market-driven exercise but even a wild guess is appreciated.
