Yep, it extracts the movie title from the filename (removing the extension), searches movie-list.com for that movie (via google!). It then searches for any .mov trailers on the page and downloads the first one it finds. As I said, I've assumed that each movie has it's own folder, and it just saves each trailer as "trailer.mov" in the movies folder.
You can tell it to only download files > Xmb, which is my way of filtering quality. Movie-List generally lists trailers from high quality to low, so if you set a high limit then you'll get the 1080 versions. I default to 60mb as I'm happy to take the low quality versions. You can also tell it to skip files where a "trailer.mov" already exists.
I've rushed this out a bit, so if you have any ideas as to how it could be improved, let me know.
@SimplyC - Nice little app.
If you save trailers.mov in each movie folder, then wont movingpictures scan those files into the database?
I thought it would be better to have option to scrape the movie title from the directory name,
alternatively an even better way would be to scrape the movie name from movingpictures.db3 file
