I think it's important to ask yourself who will buy your product and whether you will you lose customers if you can't give them that editing effect. If you notice that your clientele are requesting this technique then you can always make it an upcharge and buy the equipment you need then. Basically, I don't think that it's worth it to you at this time. Shoulder that burden after you start getting clients and can spread the expense/risk around and can write it off as a business expense on your taxes. I speak from experience. When I first started doing wedding videography I invested in so much extra "stuff" because I was convinced I needed it to attract customers and to create great videos. Much of it turned out to be unnecessary.Would this be a profitable endeavor if you're still learning basic video making?
