A still render gets looked at for about a second. A moving one gets watched for fifteen, and watching for fifteen seconds is how someone decides to book a viewing.
The catch is that a walkthrough film built from stills is not a camera moving through your model. It is generated motion. Knowing exactly what that means is the difference between a film that works and one that quietly looks wrong.
Pick the views first
Two to four is the useful range. Choose them like a photographer, not like a surveyor:
- The establishing shot. The whole building with enough context to place it.
- The hero space. Whatever actually sells the property — usually the main living space or the kitchen.
- One detail. A material close-up, a stair, a window reveal. Detail is what makes a place feel real rather than rendered.
- The view out. If there is one, it belongs in the film.
Resist adding every room. A film that visits eight spaces in forty seconds is a slideshow with motion blur.
Order and timing
Put the best shot first. Not second, not "building up to it" — first. Property video loses most of its audience inside twenty seconds, so a slow build is a slow goodbye.
Hold each shot three to five seconds. Shorter feels frantic; longer and the generated motion starts to show its limits, because a move that reads beautifully for three seconds starts to warp at eight. Total length: thirty to forty-five seconds for social, sixty at the very outside.
What generated motion does badly
- Long moves. The further the camera travels, the more the model is inventing, and invention wobbles. Short, contained moves are far more convincing than a long dolly.
- Going through doorways. Passing through an opening requires knowing what is on the other side. From a still, nothing does.
- Continuity between shots. Two clips of the same room from different angles will not agree perfectly on where the sofa is. Cut between different spaces rather than around one.
- People. Generated figures in a generated move are where the uncanny lives. Keep the film empty.
Finish it properly
Quiet music, captions burned in, and the address or the contact at the end rather than the start. Most of this is watched muted on a phone, so the words on screen carry the whole message.
Common questions
How many renders do I need for a walkthrough film?
Two to four good views. More is not better — eight rooms in forty seconds is a slideshow.
Is this the same as a real 3D walkthrough?
No. It is generated motion built from stills, not a camera travelling through real geometry.
How long should the film be?
Thirty to forty-five seconds for social, sixty at the outside. The best shot goes first.
Should it have music and captions?
Quiet music, and captions always — most property video is watched with the sound off.
