Curly brace questions

I’ve been using the curly brace trick for about a month and not seeing much difference with matching… and I’m wondering if it’s because I’ve got too much going on with the file names. My format is “title (year) {imdb-curly}.resolution.videoformat.soundformat.source.ext.” Does anyone know if having all that additional data at the end would be causing problems?

Thanks!

Make that
title (year) {imdb-curly}-[resolution.videoformat.soundformat.source].ext

Thanks!
