One way of saving costs is by reducing the amount of architectural walkthrough content in the video and increasing the amount of lifestyle footage (e.g Shutterstock footage). One second of 3D animation is more expensive than one second of lifestyle video from Shutterstock. For example, one 1 min video with 20 secs of 3D animation will be cheaper than a 1 min video with 40 secs of 3D animation. Another way of saving costs is to blend drone footage of the surrounding area with the animation, rather than asking the studio to re-create the whole area in 3d. If you’re new to drones, then this guide is a good place to start to get a understanding of how these are used within the context of 3d rendering.
