IPi Mocap Studio Changelog
From iPiSoft Wiki
Here you can find history of recent versions of iPi Mocap Studio.
iPi Mocap Studio has built-in auto update functionality. Auto update feature is configured so that checks for update are made once per day. It helps to reduce the start time of the application. If you want to update ASAP — you can use the Help > Check for Update menu item.
Note that both these features require Internet connection. Alternatively (in case of troubles with auto update), you can download and run the updated installation program from our website.

ver. 2.4.0.154
|
Download |
N E W F E A T U R E S:
- Multiple actors support (Standard edition only).
- See this article for details.
- Multiple video cards support (Standard edition only).
- See this article for details.
- Batch processing (Standard edition only).
- See this article for details.
- Removed 2GB file size limitation for video export.
- Official support for tracking with 8 color cameras (Standard edition only). Support for 8 cameras is especially actual for multiple persons tracking.
- Recent releases already support 8 PS Eyes, but this feature is marked as "experimental" (there is a corresponding warning). In this release we just remove this warning. Some of our customers successfully track with 8 cameras for a long period of time, so we may consider it as stable now.
- Minor improvements of tracking accuracy.
- New Jitter Removal algorithm now preserves more details of the motion. Default value for Jitter Removal changed to 2.
- Inverted mouse wheel behavior in viewport.
- A motivation for this change was to make the behavior consistent with multi-touch "pinch to zoom" gesture, as well as with the majority of other apps. In the future releases this may become a user-defined setting. Sorry for inconvenience.
- Minor improvements in look-and-feel of Jitter Removal Options dialog.
- Tabs area width is restored from the previous launch of application (same as with window size).
New features of Standard edition can be tried in other editions. When using these features, projects are saved in the trial format prohibiting the export of animations.
B U G F I X E S:
- Fixed video opening error when project and video are located on different drives.
ver. 2.3.2.150
|
Download |
N E W F E A T U R E S:

- MRU lists for poses in the context menu for a hand key frame.
- Recently saved/loaded hand poses are automatically put to the context menu for hand key frames of the corresponding hand, just below the standard poses. So to apply one of those poses you do not need to click Edit > Load Pose from File, then Ctrl + V. Just open context menu for a key frame and choose a pose.
B U G F I X E S:
- Fixed error when clicking on markers during the calibration process.
ver. 2.3.1.149

N E W F E A T U R E S:
- Hand keyframing (poses for fingers). See Getting Started guide.
- Changes in timeline:
- Multi-colored tracks and items.
- New context menu, including items for toggling the visibility of particular tracks.
- Zoom and Scroll to Current Frame buttons — moved to the right side above the timeline.
- Strobe settings moved to the context menu of the strobe marker, and the strobe track made invisible by default.
- Tracking option for spine:
- Stiff Lower Spine (like version 1.x — default for new projects)
- Flexible Lower Spine (previous default behaviour of version 2.x)
- Renamed tracking option for shoulders (now with drop-down list instead of checkbox):
- Shoulder position calculated from arm position
- Shoulder position tracked from video (useful for some movements like boxing or dancing)
- Improved calibration for dual depth sensors:
- Removed 90/180 degrees setting (no longer needed — auto-detected in new version).
- Better accuracy of the ground detection.
- Implemented auto-restore of last size and state (normal/maximized) of the main window at application startup.
- Undo also restores previous bone selection.
- Initially active tab for calibration projects is now set to Calibration; for action projects to Tracking.
B U G F I X E S:

- Timeline zoom and scrolling.
- Color picker tools for actor appearance items.
- Additional capabilities in 3D Viewport navigation:

N E W F E A T U R E S:
- Support for hand/prop tracking using data recorded from motion controllers. See Getting Started guide.
- Warning. Projects with motion controller data cannot be open by previous versions of iPi Mocap Studio.
- Long-awaited Undo/Redo for manual editing and for automatic processing. Standard shortcuts Ctrl+Z, Ctrl+Y work.
- Additional commands for working with pose (under menu Edit):
- Copy pose of selected bone's children (and all descendants) only. Available only as menu item. Useful for copying hand poses (without rotation of hand's joint itself).
- Paste pose to all frames within ROI (Ctrl+Shift+V).
- Save pose to a file from the Clipboard (Ctrl+P). Using this and the following command, you can make a sort of a pose library.
- Load pose from a file to the Clipboard (Ctrl+L).
- Navigating through skeleton using the keyboard:
- Go to parent bone ([)
- Go to child bone (]). Moves selection to a first child. If there are no children, moves to a next sibling bone (or parent's sibling, etc). Makes a full walk around the skeleton.
- Cycle through bones of the same level of hierarchy (Shift+[, Shift+])
- Improved skeleton visualization. Joint size and bone thickness are proportional to bone length. Now fingers are much easier to edit.
- Improved calibration accuracy for dual depth sensor configuration.
- Improved accuracy of feet tracking with PS Eyes.
- Improved actor's model.
- Menu item Help > Keyboard Shortcuts shows all keyboard shortcuts in one place. The same information is available as a wiki page.
B U G F I X E S:
- Opening video causes Device does not support multi-level texture width and height values that are not powers of 2. error with some video cards.
- Running calibration with ROI less than 8 frames crashes the app.
ver. 2.1.3.143

Download |
N E W F E A T U R E S:
- New items in Edit menu for coping parts of body position:
- Copy Pose of Selected Bone — copies rotations for selected bone to Clipboard. For paste use Paste Pose menu item.
- Copy Pose of Selected Bone with Children — copies rotations for selected bone and all its children to Clipboard. For paste use Paste Pose menu item.
- If video from depth sensors like MS Kinect or ASUS Xtion has RGB channel then now you can colorize 3D point cloud using data from RGB camera. To turn on this feature please use View > Color Point Cloud with RGB Data menu item.
- Added iPiMocap: namespace only for MotionBuilder-optimized FBX output (Export > For MotionBuilder (FBX, BVH) menu item).
- Improved look and feel of Open and Save file dialogs for modern operating systems like Windows 7.

N E W F E A T U R E S:
- Head tracking. Enabled by the Enable head tracking checkbox on the Tracking tab.
- Note. This version does not track face orientation, that is head rotation around Y axis.
- Switched places of Track Forward and Track Backward buttons. The new placement is more intuitive, but may cause confusion for existing users.
- Improvements in Jitter Removal.
- Simplified rules for auto-adjusting the Region of Interest. Now it's touched only if the tracking starts when the current position is outside the ROI.
