I absolutely love this thing! I've been creating Halo Reach videos for my clan for the past few months, and there are very few issues that I have with it. When I record on my computer, there are 3 or 4 tiny half-circles at the top of the screen (hardly noticible) and sometimes a small (maybe 1-pixel) line that splits off from the rest of my screen, but all of that can be fixed with the video cropping tool that they have included with the software. I know a few other people who have bought capture cards for cheaper and sometimes it runs a blue line down the right side of the screen if they record in high quality, this does better quality with no blue line.
The basic video editing operations such as trimming, splitting are available from the last menu—Edit—and they also snap into view if you double click a clip in your timeline. The Trim tool simply adds start and end handles to the preview window's scrubber line, but you can do the same thing from the main timeline by tapping "Set start point" or "Set end point."
Free video editing software often comes with legal and technical limitations, however. Some widely used codecs require licensing fees on the part of the software maker, meaning they can't offer free software that can handle these standard file formats. That said, the impressive open-source Shotcut does a lot of the same things that the paid applications in this roundup do, including things like chroma-keying and picture-in-picture. Shotcut is completely open-source and free, while another free option, Lightworks has paid options that remove a 720p output resolution limit. Note also that both Shotcut and Lightworks run on Linux as well as Windows and Mac.
Creating a new video from existing ones becomes really easy by using Windows Movie Maker. It gives me the ability to prepare, edit, and deliver videos to my audience and clients, and they really love the material I deliver. I simply thin that the best thing freelancers can do is to communicate what their service is about with an awesome and engaging video.
