VLC - Automatic Deinterlace

It gets old to manually select deinterlace options for videos, so I enable it by default.

Click Tools > Preferences
Under Show Settings (lower left) select All.
In the left column, expand Video (click the + beside it)
Select Filters (not expand).
In the right column under Video filter module (first section) check the Deinterlacing video filter option.
Expand the the Filters section in the left column. (click the + beside it)
Select Deinterlacing.
In the right column select the preferred modes. I like X.
Save settings.
