The correct sentence from the video is: "It would, pointed out one observer, have been cheaper to hire a prostitute for the day than to buy an image of her." The "pointed out" part is a clause inserted into the main sentence, so you can re-arrange it to make it a little easier to understand.

For example: "One observer pointed out that it would have been cheaper to hire a prostitute [...]".

Or: "It was pointed out by one observer that it would have been cheaper to hire a prostitute [...]".
