How to get nicer Youtube video files names?

Hi

Does anyone know if I can download the Youtube videos with nicer names?

See the file name below. It grabs those additional ugly naming from the url.

The_ultimate_gold_shader_in_Cycles-nsem2HjwZQU.mp4

It would be nice if the file name is actually The_ultimate_gold_shader_in_Cycles.mp4

I know I can pass this to youtube-dl -i -o "%(title)s.%(ext)s" to grab real names. I just do not know where and how I can pass this to the OcDownloader app.

thanks
