To buy Plug İn for Tv Generic

Hi Guys,
I need to set up a TV program. I'm looking for a plug-in in this video. The duration will be between 30 seconds and 1 minute. This way I want to have the video format ready-made fotmat to change the images later. But I didn't see a site that sold the ready-made plug-in. Would you please recommend the sites I'm going to buy? Thanks
