This video is an example of a procedure that allows the designer to quickly create multiple “walk through” animations for client design proposals and reviews.
Creating just one fully rendered walk-through animation could take several days when using Revit. Using this procedure, the designer can create multiple video animations while providing the owner with photo-realistic images of their proposed building design.

The procedure incorporates rendered, image snapshots into a Revit “shaded with edges” walk-through animation.
It’s a quick and simple way to walk your client through several design option proposals; while giving them a flavor of the lighting and materials.

We recently updated this Revit model with our new Bradley Advocate AV-Series lavatory system in a matter of minutes. We then rendered the scene for engineering.
Here are the 5 Basic Steps I used:
1. Create a walk-through (set path & camera) from a plan view in your Revit model. Once completed, I changed the original Property Path Settings’ “walkthrough frames” from the default 300 frames to 1200 frames.
First, by adding frames (300 to 1200); this slows down the video and provides smoother movement as I am turning corners inside this locker room.
Second, I can further decrease or increase the Accelerator values to slow down (going into a path curve) or speed up (coming out of path curve).
2. Export the walk-through to an AVI file from Revit. Make sure that you are in an “Edit Walkthrough” view.
Use the Microsoft Video 1 compression when exporting to an AVI file.
3. Go to Frame #1 and render the view. When the view completes rendering; save the image in the project file AND export the image to a project folder.
Push the Play button and continue to the next “interesting ” spot on your camera’s path…then push Pause. Render the view’s image. As you complete the walkthrough; render the last frame.
Plan your best “stop, view and render” points along the camera path. This provides the viewer regularly scheduled (maybe every 10-15 seconds) stop & views.
4. Give each exported image file a name that uses the frame number at the spot in the walk through animation. This will be helpful for inserting the correct image at the correct “splice point” in the next step.
I insert the video 1st on the Camtasia timeline. Next I insert the 1st & last images on the timeline at the beginning and end of the video.
I play/preview the video in Camtasia and stop at the corresponding frame of the rendered image. Next, I use the “split video” command. Then, insert the appropriate rendered image into that frame.
Finally, using the Camtasia “Produce Command”; the final video with the integrated rendered images is produced in a variety of video formats for both PC, Mac, iPhone, iPad or iPod.
