Troubleshooting
Video codec problems
Potential problem: cannot open Kinect video in iPiStudio.
Possible cause: a broken Microsoft AVI Splitter installation.
One of the symptoms of this problem: unable to play Kinect video with Microsoft Media Player.
Usually this happens when users install third-party (non-Microsoft) video codecs.
At least a few users users reported this problem.
Solution:
1) For Windows XP - install (or re-install) Microsoft Media Player version 9.
2) For all platforms - the following command run with Admin rights should repair the default Microsoft AVI splitter installation:
regsvr32 quartz.dll
(On Windows7 use it like this: Start -> All programs -> Accessories -> Command Prompt -> (right click and select "Run as administrator") -> regsvr32 quartz.dll).
We are working on a more reliable solution for this problem but it may take some time to implement.
Tracking errors caused by wrongly configured background
This is a very common problem. It can be the source of most dramatic tracking errors.
First few seconds of your action video should have clear background (no actor in view of cameras). Failure to provide clear background will result in wrong operation of tracking algorithm.
You can quickly check your background by pushing and holding "Background" button at the top of iPiStudio window. If you see the actor in background then your background is wrong.
To fix this issue, you may need to re-shoot the video. If you have clear background at the end of your action video (or in some other part of your action video, for example, in the middle), you can fix the problem by moving the "Background" region on timeline.
