If it matters, I just used MS Paint and used the resize option (pixels, not percentage option) and told it to become 1280x720.
MS Paint works if you just need to resize, but if the source image is not the right aspect ratio then you'll end up with an image that appears squished/stretched in one direction, and Paint is terrible for precision cropping. I'll probably install GIMP when I get home to sort this out.
My issue is that I'd rather not crop because my camera isn't great and I want to make full use of the CCD to get decent quality :/
Adding black bars would be better for my case, but I'm unsure if that's alright.
