This Lambda Films video blog will cover some specific terms you may come across in your
camera settings and the post-production software you use to edit with.
Video production terms
Aspect ratio refers to the shape of the footage, usually referred to as two numbers which you can interpret
in the same way as you would interpret parts in a recipe. For example, 4:3 refers to a
frame size as a ratio of four wide and three high. It doesn't refer to an exact measurement.
Examples of 4:3 would be a classic non-widescreen TV or projector. It's fairly box shaped but
still technically a rectangle. More commonly in HD shooting, you will see 16:9 which is
standard widescreen - noticeably wider than it is tall. You'll notice films in cinema
can be even thinner and wider than this. Frame rate refers to the number of still images
that play per second to create the illusion of movement. Like drawing a flipbook, the
more pictures per second, the smoother the motion because more images are used to recreate
the movement on the screen. Twenty four frame per second is the classic cinema standard,
faster frame rates like twenty five or thirty frame rates are used by TV and Video, whereas
sixty frames per second can be used to create slow motion video. This is because there's
more information in a second of video to slow down. Hopefully this clears up some of these
seemingly odd terms, they're important to understand and once you get your head around
them, they're pretty easy to remember. Thank you for watching and remember to subscribe
