12.2.1 Frame skip

The frame skip number (n) is used to reduce the frame rate of the output. The exporter will perform

down sampling by skipping every n frames (n = 0 to 10) of the original file (after smoothing) in the output.

Note that if no smoothing is specified, no smoothing will be applied when using frame skip.

The output rate is given by: original sample rate / (1 + skip factor).

For example, an MVN file recorded at 100 Hz:

frame skip = 1, output frame rate = 50 Hz

frame skip = 2, output frame rate = 33 Hz

frame skip = 3, output frame rate = 25 Hz

Or for example, an MVN file recorded at 240 Hz:

frame skip = 1, output frame rate = 120 Hz

frame skip = 2, output frame rate = 80 Hz

frame skip = 3, output frame rate = 60 Hz

So, take care when selecting your preferred motion capture update rate if you need a specific output

frame rate, it can make your life easier.

12.2.2 Overwrite first frame with T-pose

To align the captured motion data with an animation model, the T-pose will actually be inserted before

the first frame of the data. The position and orientation of all segments can be found in the MVNX file in

the <tpose>section.

12.2.3 Output Presets

Several Output Presets are available that fit specific applications:

 Motion Builder

 3D Studio Max

 Poser 6

12.2.4 Output Unit

Select the desired output unit that is used in the animation program.
