In Motive, the Edit Tools pane can be accessed under the View tab or by clicking icon on the main toolbar.
The Edit Tools pane contains the functionality to modify 3D data. Four main functions exist: trimming trials, filling gaps, smoothing trajectories and swapping data points. Trimming trials refers to the clearing of data points before and after a gap. Filling gaps is the process of filling in a markers trajectory for each frame that has no data. Smoothing trajectories filters out unwanted noise in the signal. Swapping allows two markers to swap their trajectories.
Read through the Data Editing page to learn about utilizing the edit tools.
Trim on Selected: Trim on Selected trims selected trajectories within the selected time region. Gaps outside the selected time region are not trimmed. Trajectories that are not selected are untouched.
Trim on All: Trim on All trims all trajectories within the selected time region. Gaps outside the selected time region are not trimmed.
Leading: Default: 3 frames. The Trim Size Leading defines how many data points will be deleted before a gap.
Trailing: Default: 3 frames. The Trim Size Trailing defines how many data points will be deleted after a gap.
Smart Trim: Default: ON. When enabled the Smart Trim feature will trim trajectories based on the trajectory history. It is often not needed to delete numerous data points before or after a gap, but there are some cases where it's usefully to delete more data points then others. Automatic will delete an appropriate number of frames, up the the Leading and Trailing limited defined by the user.
Minimum segment size: Default: 5 frames. The Minimum Segment Size set the minimum size that a trajectory can be cut down by. For instance with a Minimum Segment Size of 5, if a trajectory is continuous up to frame 100, is gaped during frames 101 and 102, is continuous for another 4 frames, is gapped at frames 107 and 108 and is continuous after, no trimming will occur on the 4 frames in the middle of the two gaps. Use this to define the smallest trajectory that is touches by the trimming feature.
Gap size threshold: Default: 10 frames. The Gap Size Threshold defines the minimum size of a gap that is affected by trimming. Any gaps that are smaller than this value are untouched by trimming feature. Use this to limit trimming to only the larger gaps. In general it is best to keep this at or above the default, as trimming is only affective on larger trajectories.
Find Previous: Find Previous searches through the selected trajectory and highlights the range and moves the cursor to the center of a gap before the current frame.
Find Next: Find Next searches through the selected trajectory and highlights the range and moves the cursor to the center of a gap after the current frame.
Fill Selected: Fills the currently selected gap.
Fill All: Fills all gaps in the currently selected track.
Fill Everything: Fills all gaps in all tracks of the timeline.
Max Gap Size: The maximum size, in frames, that a gap can be for Motive to fill. Raising this will allow larger gaps to be filled. However, larger gaps may be more prone to incorrect interpolation.
Interpolation: Sets which interpolation method to be used. Available patterns are constant, linear, cubic, pattern-based, and model-based. For more information, read Data Editing page.
Pattern Target: The target marker which the selected interpolation will be performed on.
Smooth Selection: Applies smoothing to the selection portion of the track.
Smooth Track: Applies smoothing to all frames of the track.
Smooth All Tracks: Applies smoothing to all frames of all tracks of the currently selected timeline.
Max. Freq (Hz): Determines how strongly your data will be smoothed. The lower the setting, the more smoothed the data will be. High frequencies are present during sharp transitions in the data, such as footplants, but can also be introduced by noise in the data. Commonly used ranges for Filter Cutoff Frequency are 7-12 Hz, but you may want to adjust that up for fast, sharp motions to avoid softening transitions in the motion that need to stay sharp.
Find Previous: Jumps to the most recent detected marker swap.
Find Next: Jumps to the next detected marker swap.
Markers to Swap Selects the markers to be swapped.
Apply Swap: Swaps two markers selected in the Markers to Swap
