Wow, that's some limited information there.
Do you need an OS in that budget? Peripherals/Monitor? etc.
Are you located in the US? I just want to make sure. It doesn't really help if you convert a budget to USD if you play to buy in another country/currency.
As far as video editing goes, you want cores/threads and RAM.
A Xeon or i7 would be a great starting point, but it'll depend what you need within that $1,000 budget.
