adding keywords to video files

[limar500]

hi

I use IPTC for managing keywords for my image files (.jpg, .gif etc.)
I would like to add keywords to video files as well like .wmv, .avi, .mp4 etc.

I realize it's not possible to add IPTC information to video files in XnView, is there any other way to manage (add/edit/delete) keywords in video files in XnView? maybe with the help of some kind of plugin?

sorry currently no way
