There’s another way that video shooting differs from stills shooting – namely, that photo editing is a useful skill to have, but video editing is a necessary one. All that footage, however steady it is, will be worth nothing unless you can cut it together, and for that you’ll need to start getting familiar with dedicated editing software. It’s probably worth looking for some tips online or maybe enrolling in a short course to give yourself a head start, but you should be able to pick up the very basics without too much trouble. Adobe Premiere Elements is a good stripped down programme to grapple with first.
