AllCampaignsRemastered - Updated mod for all Campaigns

Is it possible to link video clips to a campaign? The first one at the beginning, showing the wedding, and the final one with Isabel/Biara.

I tried, and they even played, but they were replaced with the starting logos. I don't know how to make them play at the beginning or end of a mission. I think it's hardcoded in the engine, and anyway, the video files need to be placed in the game's video folder, which isn't ideal.
