I don't really like promoting piracy but I make an exception for a few things. Pirate a copy of Sony Vegas, you won't get that level of functionality for less than £600. Due to it being quite possibly the most pirated piece of software ever YouTube is absolutely stuffed with tutorials, it's how I learned to use it back in the day. Adobe Premiere is also quite popular but due to it being unpirateable there are fuck all tutorials on the tube and all the ones on there are far too advanced for noobs like me, they all assume I make a living with it already.
For recording software I found Fraps to be the best. It's an absolute pig for resources and loves chewing through RAM but if you have a decent PC it can't be beat. I tried loads and although most of the others were much less intensive, they sacrificed image quality and / or sound. If you want Fraps let me know as I have a paid up account so can download whenever.
For voice recording you wanna use Audacity, very easy to use, loads of options and this means you'll have separate audio and video files so you can edit to your heart's content. It's also free.
Anyone who says you need to spend big bucks on hardware is talking shit. My old vlogs were all recorded on my Samsung Galaxy S3, sound and video, and the quality was fantastic.
Rendering takes ages so try plan it to let your PC do it overnight. I dunno if GPU rendering is decent nowadays but when I tried it it fucked up every single time, a pain in the arse when you leave it overnight only to find it's failed in the morning.
I'll add more to this as I think of it.
