Change the total duration of a walkthrough animation, change its speed at different points, or reset the camera targets to previous positions.
- Open the walkthrough and set up views.
- On the Options Bar, click
(Walkthrough Frame Edit button).
The Walkthrough Frames Dialog displays.
If you want to... Then... change the total duration of the walkthrough animation
increase or decrease the total number of frames or the number of frames per second. The default duration of the entire walkthrough is 20 seconds.
The total time of the walkthrough is based on the number of frames and the frames per second.
For example, 300 frames at 15 frames per second results in a 20-second walkthrough. To produce a walkthrough that is 40 seconds total duration, change the frames to 600 or the frames per second to 7.5.
change the speed of a section of the walkthrough
clear the Uniform Speed check box and enter a value for the desired key frame in the Accelerator column. Valid accelerator values are between 0.1 and 10. The Accelerator is used as a factor to change the speed (distance per second) of the camera from one key frame to the next.
For example, when you use an Accelerator value of 0.5 on a key frame with a Speed value of 4600mm, the speed changes to 2300mm. Because the camera must travel along the complete path during the walkthrough, a change to the Accelerator value in one key frame slightly modifies the Speed value in the other key frames.
see all frames along the path
select Indicators in the Walkthrough Frames dialog. This option adds indicators along the path at each frame location, not just key frames.
make the camera travel along the path at a uniform speed
select the Uniform Speed option (default).
