Hi!
I use Fraps and Adobe premiere pro 5.5 and my pc has 4 Gb of ram.
It takes about an hour to render and about 40 mins to export a 20-30 min long video.
So, with 1 Gb or 512 Mb of ram it will take very long and you won't be able to do anything on your pc while the video is being rendered/exported.
I suggest you buy more ram!

If budget is a issue I recommend using Movie Studio Platinum. Also builds your skills if you want to buy into Sony Vegas Pro.

The best one I use is Sony Vegas Pro 11, and if your smart enough, you can get free or you can buy it ofr like 500 some dollars or whatever!

You'll need a much more powerful computer rig. I personally wonder if you are running this YouTube channel behind your parents back, providing that you are still with your parents.

With the products that you have, creating professional videos seems simple enough. You shouldn't need to upgrade at the moment. Much more powerful computer can cost maybe $400-600, with the computer being at least 4x more powerful than what you should have at the moment, which is much better than buying a full set of Adobe products.

And for practicality, buying a more powerful computer means that you don't have to do something else while the computer is rendering.

Hopefully my advice helps you, while my computer is complete toast at the moment.

I use Bandicam for recording ans vegas pro to edit my videos i only have 2 gb ram and it will take a lot of time if i render a 1 hour video it last about 12 hours !! and if i use someones computer it has an 8gb ram i render 1 hour video in 30 mins. only i suggest that u buy a PC that has a good processor and a lot of rams.

I use and like AVS video editor and AVS audio editor. They fulfill all the needs for uploading videos to youtube so far, and they are not too hard to use for the most part.
