Resources for practicing post-production?
So I'm not sure if this is the right place to post this, and I apologise if it isn't.
I've been doing music tech (Mostly audio recording, mixing and mastering) for a couple of years now but one thing I've been wanting to get my hands on and never done properly is audio production for film, I want to try Foley, Sound design and writing original music.
I was wondering if it was possible to get hold of clips of film that had the original on-site recorded audio but nothing else? I realise that this is quite a niche thing to ask for and that such resources probably aren't readily available on the internet, but I thought it'd be worth asking to see if there was anything I could get hold of to help me so I could give it a go and have a play around without having any obligations to produce a product.
I know I could just cut the audio from a film clip and do it that way, which is what I'm sure I'll end up doing if I can't find anything else, but it would be nice to have dialogue as well as it being from something I've not seen before.
