After you apply a filter to a layer or group, the filter is represented in the following places in the Motion project window, allowing you to make adjustments:
In the Filters Inspector, where you can turn the filter’s effect on or off, select and delete the filter, or adjust its parameters using sliders and other controls. See Adjust filters in the Inspector or HUD. For a list of parameter controls available for each filter type, see Filter types overview.
In the canvas, where you can manipulate the filter’s onscreen controls (where available). See Adjust filters using onscreen controls.
In the Layers list and Timeline layers list, underneath the layer or group the filter was applied to, where you can select the filter, turn its effect on or off, reorder it, or lock it to prevent modification. See Layers list overview.
In the Timeline track area, as a purple bar underneath the blue bar of the layer or group it was applied to, where you can select the filter and modify its timing by slipping or trimming the bar. See Edit in the Timeline track area.
In the HUD, where you can adjust many filter parameters using sliders and other controls. See Adjust filters in the Inspector or HUD.
