Film making enthusiast, music dude, insomniac.
I've made music since grade 8. And growing up, there are a decent amount of free DAWs (digital audio workstations) that you can use if you're going on a $0 budget.
Here's a list of free ones I know:
-Ardour (Only for MAC and Linux)
There are also a bunch of free VST plugins (virtual instruments) you can find on the internet. Here's a few:
-DSK Overture (If you go on DSK's website, they have a lot a free orchestral vsts for you to use)
-There's definitely more out there that I didn't mention
If you're looking for straight up film scoring but don't know how to do it. You should check out Filmstro. It's free but they also have more features if you pay for a premium license I believe.
My personal preference for making all music though is Fruity Loops, and has always been Fruity Loops. Buuuut remember, it ain't always about the software, it's mostly about your creativity.
If you really want to get a natural tone in scenes for dialogues. Let your actors improvise more rather than having to memorize lines word for word, especially if they're non-actors it works real well.
Well as a computer systems tech student, I'd recommend the Intel Core i7 over Xeon. The Core i7 is the more stable processor.
In my opinion, I think the quality of films are dependent on how you use your camera, how your scenes are set up (lighting, location, etc.), and how you direct everything overall. I usually just consider the resolution as the icing on top of the cake.
