Much less than the cost of original production, perhaps only a third. Here is a case study. Below are three videos produced for the same resort. The first was an establishing 60 second video for inclusion on a destination DVD that is used widely by the island government and resorts, on the property website, YouTube and 20 other social media.

From the same base of footage we edited a marketing video that combined both the property and destination storyline in one 4 minute comprehensive marketing video that the resort uses as their signature collateral for shows, and on a custom DVD.

Finally, from the same footage we edited a music video named “Dreaming of Point Grace” for a specific promotional use by guests who want to anticipate the experience before traveling.

The cost of production of the 4 minute and 2 minute videos together was less than the cost of the original 60 second video. We were assisted by having been based at the resort that gave us extra opportunities to capture footage.
