I've created a walkthrough in Revit 2014. I exported it to an .avi file at 24 fps, but I didn't like the result because the motion seemed too fast. So I changed the walkthrough from the default 300 frames to 600 frames. Now, when attempting to create another .avi file, Revit refuses to export anything except the first frame of the walkthrough. In the export dialog, "All frames" is selected by default, the "From" and "To" boxes both say frame 1, and the length is shown as 00:00:00. If I select the other radio button to export a range of frames, the little arrows next to the boxes are still gray. I can type "600" in the "To" box, but clicking any other button in the dialog, including "OK," changes the "600" back to "1." And even if I type "600" in the "To" box, the length is never shown as anything other than 00:00:00. Clicking "OK" will create an .avi file, but one that contains only one frame of the walkthrough (the first one).
If I go to the "Edit Walkthrough" ribbon, and click on "Previous Key Frame" until I get to the first one, and then click "Play," the entire walkthrough plays as expected. It just cannot be exported.
I tried going to the "Walkthrough Frames" dialog, unselecting "Uniform Speed," and entering "24" in the frames per second box, but this had no effect - Revit still will not export the walkthrough.
I checked under "Options" and hardware acceleration is on.
Am I going to need to delete and recreate the walkthrough? Is there some setting I'm missing?
Thanks,

maybe this can help.
To export a walkthrough:
The Length/Format dialog opens.
You can select which control in the path you want to edit from the drop-down menu. Controls affect the position and direction of the camera.
Dragging the Camera to a New Frame
Changing the Walkthrough Path
The key frames become controls along the path.
Notice that the value in the Frame text box stays constant.

Removing Key Frames
Displaying the Walkthrough View when Editing
As you edit a walkthrough path, you may want to see the results of your changes on the actual view. To open the walkthrough view, click Modify Cameras tabWalkthrough panelOpen Walkthrough.
ennujozlagam,
Thank you for the reply. Perhaps my OP wasn't clear. The difficulty occured at Step 3 of the directions you listed, which state "As you change the number of frames per second, the total time automatically updates." Revit had this locked at 00:00:00 and never updated it, regardless of what was typed in the other boxes in the dialog.
However, I was able to get Revit to export the entire walkthrough, by adjusting the lighting settings. I had placed the sun at a specific date and time. This confused Revit into thinking it was exporting a solar study, rather than a walkthrough (even though "Walkthrough" was selected on the "Export" flyout). Since there was not a range of time defined in the sun positioning (start and end hour were the same), there was only one frame in the "solar study." I changed the sun position to a defined azimuth and elevation angle, rather than a date and time, and then Revit would export the walkthrough.
Oddly, even though it would not export the time-defined sun position setup as a walkthrough, it would play the walkthrough with this setting in the walkthrough edit mode. To this end user this looks like a "bug," but maybe Autodesk considers it a "feature." Fortunately for the intended audience of this particular walkthrough, exact solar positioning is not critical.
Thanks,

Hi, this is a few years to late, but for the benefit of other readers, I too had this issue and found it was solved by changing the rendering settings of the model. In particular changing the lighting to the "Still" setting. It was previously on multi day. I also found the single day produced the same problem when it came to exporting.
In summary:
Make sure your lighting settings are set to 'Still' or 'Lighting' to allow proper export of the video.
Hey Ethan.. Dude you've saved me some hundreds of neurons bro )) I was striving to get this stuff to work. And the solution was that simple. Appreciate it. Cheerz
