‌Path Filtering Dialog ‌

The path filtering dialog controls the filtering of the camera path and field of view, if any, that takes places after solving or directly upon your command. Launched from the Filtering Control button on the solver panel or the Window/Path filtering menu item. It displays values for the selected camera or object (in the viewports), or more normally the camera or object listed as the active tracker host (on the toolbar).

Warning : Path and FOV filtering CAUSE sliding, because they move the camera path AWAY from the position that produces the best, locked-on, results.

The filtering is best used as part of a workflow where you only filter a few axes, lock them after filtering, then refine the solution to accommodate the effect of the filtering.

The selection of solve or seed path and whole shot or playback range are available only interactively; the solving process always filters the whole shot into the solve path (if enabled).

Frequency. Animated spinner. Cutoff frequency controlling how quickly the parameter is allowed to change, in cycles per second (Hz), ranging up to at most 1/2 the frame rate.

Strength. Animated spinner. Controls how strongly the filtering is applied, ranging from 0 (none) to 1 (completely filtered at the given frequency).

X/Y/Z. Checkboxes. One checkbox for each translational axis, controlling whether or not it will be filtered.

Rotation. Checkbox. Controls whether rotation is filtered. Note that there are no separate channels to filter or not for rotation.

Distance. Checkbox. Controls whether the camera/origin (camera tracks) or object/camera (object tracks) distance is filtered or not. Primarily intended for difficult object tracks where most error is in the direction towards or away from the camera.

FOV. Checkbox. Controls whether or not the field of view is filtered.

To Solve Path. The filtered path (and/or FOV) is written into the solve tracks (normal default).

To Seed Path. The filtered path (and/or FOV) is written into the seed tracks, which is available only interactively and is intended to generate data for hard or soft locking the axes.

Whole Shot. The entire shot is filtered (normal default).

Playback range. Only the portion of the shot between the green and red playback range markers on the timebar will be filtered. For interactive use (only), this can be quicker and easier than setting up an animated strength value to adjust a portion of a shot. The filtering will blend in and out at each end of the playback range.
