Does anyone have the names of companies or website links where one can preview and purchase specific media loops for use in theatrical projection? We are doing a rendition of Les Mis and in lue of spending x-thousand on a media server, we opted to use Power Point. However, we need various moving images including muzzle fires, shimmering night sky, shooting star, rushing river, etc. I've already got all of the static images locked down. Any suggestions would be great.
