Working with the Pre Encoding filters list
If you choose multiple Pre Encoding filters, you can turn any combination of the filters on or off. This capability is useful if you want to view versions of your project with different filters applied. If you turn off a filter, be aware that when you save the preset, or switch to another pane, the Media Encoder removes the filter from the list. You can also change the order in which the Adobe Media Encoder applies the filters.
To activate or deactivate Pre Encoding filters:
Click the Eye icon to the left of the filter name to deactivate the filter. Click again to activate it.
To change the order of the filters:
Drag a filter to another location in the filter list.
To delete filters from the list:
Select a filter from the filter list, and click the Remove button
