Now one big question I know is on everyone's minds. APS-C or Full-Frame? Now the obvious answer is that if you're making money with the camera, go full-frame, if not, APS-C. But actually it's not that simple. First, there's no reason someone doing photography as a hobby shouldn't get a full-frame camera, other than the fact that they cost a whole lot more. But if you can afford it and you want the advantages of a full-frame camera (better resolutions, better low-light photography, etc.) and you don't mind the extra bulk, then why not? And on the flip-side, if you're a pro and want a smaller, less bulky camera to take with you on a shoot, then there's also no reason to say an APS-C camera will not be worth buying... But since you're looking at the T7i, let me go over a few actual advantages to an APS-C camera regardless of your status as an amateur or professional.
There are two different licenses you can choose from with Lightworks: "Free" and "Pro." (The latter of which, as you might have guessed, requires that you cough up some cash.) The main difference between the two licenses is that the Pro version offers more features, including stereoscopic output and advanced project sharing. But the free version is still quite powerful, providing 100+ effects and supporting multicam editing.
