Reprocessing - reprocess the mvn files before exporting. Options are None, Normal Quality and HD Quality. More information of reprocessing: Reprocess (HD)
Save MVN file after reprocessing - save the result of the reprocessing to the MVN file
Force reprocessing - force the reprocessing regardless of the quality of the MVN file
Use GNSS Data - check to use GNSS data in the selected exports (checking automatically sets Reprocessing to HD Quality)

 

Exporter types

There are multiple exporters available in MVN depending on the software:

Exporter MVN Animate MVN Animate Pro MVN Analyze
BVH
C3D
Excel X X
FBX
Movie X
MVNX

 
In the Export tab, you can click  "Show Options" to access the advanced options for the selected exporter.

Below you will see the various subsections for exporter options: BVH, C3D, FBX, MVNX, Movie and Excel Exporter.


BioVision Hierarchical Data (BVH)

BVH files embed captured motion data in ASCII format which can be imported in many animation applications.

Exporter frame skip (for downsampling) - skips 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. More info on frame skip.

Overwrite first frame with T-pose - T-pose will be inserted before the first frame of the data.

Output preset - Motion Builder, 3D Studio Max, Poser 6

Output unit - there are a few options available: millimeters, centimeters, decimeters, meters, kilometers, feet, inches

Coordinate 3D (C3D)

 C3D files is a file format designed to contain 3D coordinate data, usually in the form of bony landmarks.

mceclip11.png

Exporter frame skip (for downsampling) - skips 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. More info on frame skip.

Overwrite first frame with T-pose - T-pose will be inserted before the first frame of the data.

Output data format - Most systems accept the 16 bit integer output format. However, when this is not the case, the single precision floating point (IEEE 754) can be chosen, which will enhance resolution (less output quantization).

Allow files containing over 65535 frames - In the past C3D was designed to accept no more than 65535 frames. Tick the box to allow trials longer than 65535.

Point set - There are two lists of points that can be exported, “All available points” and “External Points”. External Points are included in the “All available” selection

Excel Exporter (XLSX)

Each corresponding section of the navigator (ie. Segments, joints etc.) will have its own tab in the xlsx file, each joint/segment will have its own column, with the frames listed in the rows.

Exporter frame skip (for downsampling) - skips 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. More info on frame skip.

 

Filmbox (FBX)

FBX files is a platform-independent 3D file format which gives you access to content authored in software packages such as MotionBuilder, Maya, Unity or Softimage and  contain both position and orientation information of all 23 segments.

Exporter frame skip (for downsampling) - skips 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. More info on frame skip.

Overwrite first frame with T-pose - T-pose will be inserted before the first frame of the data.

Output preset -  option to choose “Default” and “Skeleton”. “Default” export contains position and orientation information of all 23 segments in global coordinates. “Skeleton” export contains skeleton hierarchy information in a way that is used by many common 3D software packages like MotionBuilder, Maya, Unity and Houdini.

Output unit - there are a few options available: millimeters, centimeters, decimeters, meters, kilometers, feet, inches

Time increment mode - fixed and dynamic

Start at - 0 and real time

Walk on the spot - fixes the avatar to the orgin

Movie Exporter (MP4, AVI)

Exporting movie data enables the user to export the 3D viewport of MVN to either .m4v or .avi. this facilitates presenting MVN information to audiences without the need for installation of MVN.

Resolution  - Allows you to choose the desired resolution for export. There are multiple options all the way up to 1080P.

Frame rate  - Allows you to choose the desired frame rate for export up to 120

Encoder - mpeg-4 and avi is available

MVN Open XML Format (MVNX)

mceclip15.png

MVNX contains as default, 3D segment and position data. Additional values can be exported as shown, including: 3D Position, linear and angular acceleration and velocity of all 23 segments. 3D Joint angles of 22 joints. 3D Orientation, acceleration, angular velocity and magnetic field data of all 17 MT’s.

MVNX Version  - Allows you to choose which version you'd like to export as 3 or 4

Exporter frame skip (for downsampling) - skips 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. More info on frame skip.
