Each file in there is a jump list for a single application. To find out the one you need, add or remove an item on the jump list you want to clear. Then sort the files in this folder by modified time to find out which one you just edited. Delete the file to remove the jump list.
In Windows 10, it is not possible to navigate to this path using Windows Explorer, however copying and pasting it to the address bar does work.
The Jump lists for each program are stored in "%AppData%\Microsoft\Windows\Recent\AutomaticDestinations" but they are in a binary format with an obscure name.
e.g. "8fbb9843e86d54f4.automaticDestinations-ms" (which I will refer to as .adms from now on)
It is possible to discover which .adms belongs to which program with a little trial and error.
Open a video.
Put the AutomaticDestinations folder into Detail view and Sort by
Date Modified.
Only one or two .adms should be
showing as modified in the past
minute. One is probably Explorer's list of
recent folders, the other should be
your program.
Delete one of the .adms then try to
open your program's jump list.
(Programs in the Start menu will
still show the jumplist arrow, you
have to click to see if it opens or
does nothing)
Once you have identified the correct .adms, undelete it and set the file properties to Read-only (this completely disables the jumplist)*
Alternatively, make a note of the filename and go in and delete it whenever you need to. Windows will recreate it with the same name.
* I tried changing other permissions, but it wants full write permissions or it won't work at all!?!
Just delete all files in both folders. It's safe because it's just a cache, which will be recreated. Please note, that you have to relogin, to apply the changes.

Jump lists are stored in the user profile. To view them, open the following path:
%APPDATA%\Microsoft\Windows\Recent\AutomaticDestinations
