Hi Katiemcc,
In all honesty, though there are some free options out there like Windows Movie Maker and Lightworks, having come from the world of Premiere and/or After Effects, I think that you'll find yourself limited as to what you can do with these free programs for video editing. I know you may not want to hear it, but if you are currently a student, there is a good discount available by Adobe that may be manageable for you. There are times when I'm crunching the numbers financially, but my Adobe subscription is non-negotiable. There is just so much that you can do with the suite, and in time, can actually help pay your bills. This, of course, is just my opinion and I look forward to seeing any other suggestions. Best of luck to you!
